JavaScript to add a global link next to Welcome menu in SharePoint 2010

Similarly to my post on adding a link next to the Site Actions menu in the Left Ribbon, you can add a link on the right ribbon on SharePoint 2010 pages, next to the Welcome menu.

ExecuteOrDelayUntilScriptLoaded(ExecuteDefaultLoad, "sp.js");

var _rightRibbonContainer = null;

function ExecuteDefaultLoad()
{

 var isWikiEdit = false;
 if ( document.forms[MSOWebPartPageFormName]._wikiPageMode != null )
 {
  if( document.forms[MSOWebPartPageFormName]._wikiPageMode.value == "Edit" )
    {
     isWikiEdit = true;
    }
  }

 var inDesignMode = document.forms[MSOWebPartPageFormName].MSOLayout_InDesignMode.value;
 if (inDesignMode == "1" || isWikiEdit) 
 {  // page is in edit mode 
 } 
 else 
 {  
  LoadRightRibbon(); 
 } 
}

function LoadRightRibbon()
{
 
 var ribbonContainerRowRight = document.getElementById("RibbonContainer-TabRowRight");

 if( ribbonContainerRowRight != null )
 {
  if( ribbonContainerRowRight.children != null && ribbonContainerRowRight.children[2] != null )
  {
   if( ribbonContainerRowRight.children[2].children != null )
   {
    _rightRibbonContainer = document.getElementById("RibbonContainer-TabRowRight").children[2].children[0];

    if( _rightRibbonContainer != null )
    {     
     AddHelloLink();
    }
   }
  }
 }
}


function AddHelloLink()
{
 if( _rightRibbonContainer != null )
 {

  var newSpan = document.createElement("span");
  newSpan.innerHTML = '<a class="ms-menu-a" style="cursor:pointer;white-space:nowrap;"    href="javascript:;" title="Hello!" onclick="window.location=\'/sites/test123\';return false;"><span><font color=\'#8ce352\'><b><i>Hello World!</i></b></font></span></a>';
  newSpan.className = 'ms-SPLink ms-SpLinkButtonInActive ms-welcomeMenu';
  
  newSpan.onmouseover= function() {  this.className = "ms-SPLink ms-SpLinkButtonActive ms-welcomeMenu"}; 
  newSpan.onmouseout= function() {  this.className = "ms-SPLink ms-SpLinkButtonInActive ms-welcomeMenu"}; 
  

  _rightRibbonContainer.insertBefore(newSpan, _rightRibbonContainer.children[0]);
 }
}

How to create a SharePoint Delegate Control that injects JavaScript to all SharePoint pages

Recently, I needed a way to insert some JavaScript files into all pages in all of the SharePoint site collections and sites under an entire web application.

The thought of changing all the master pages in every site collection seemed not only tedious, but unmanageable. Every time a new site collection is created, we would have to remember to modify the master pages. Also, if a site collection owner decided to use their own master pages, we would have no way of maintaining those either.

So, after banging my head trying to come up with a better solution, I stumbled upon the delegate control!

A detailed description of how it works and what it does can be found here:


The beauty of the delegate control is that you can basically overwrite anything in the master page.

I wanted to add a simple JavaScript file to all of the pages in the master page.

So I started by following the example below. I modified this code in step 12 from the hardcoded script to instead read from a JavaScript file that is located in my layouts folder.

  protected override void CreateChildControls()
        {
            base.CreateChildControls();

            string srcScript = "/_layouts/Company/CompanyScript.js";
            this.Controls.Add(new ScriptLink() { Name = srcScript, Language = "javascript", Localizable = false });
        }


The step by step process can also be found here as well: http://msdn.microsoft.com/en-us/library/ms470880.aspx

Step by step process to creating a delegate control:
1.      Start SharePoint development tools in Microsoft Visual Studio 2010.
2.      On the File menu, point to New, and then click Project.
3.      In Project Types, under Visual Basic or C#, select Empty SharePoint Project.
4.      Type EcmaScriptDelegate as the project name. Click OK.
5.      In the SharePoint Customization Wizard, choose Deploy as a farm solution. Click Finish.
6.      In the Solution Explorer, right-click the EcmaScriptDelegate project. Select Add and then New Item.
7.      In the Add New Item dialog box, click the Code group and choose the Class template. Type EcmaScriptDelegateControl as the Name and then click Add.
8.      Next, you must add a reference to System.Web. In the Solution Explorer, right-click the References folder and select Add Reference. In the Add Reference dialog, click the .NET tab and find System.Web in the list. Click OK.
9.      In the EcmaScriptDelegateControl file that is displayed, add the following using statement.
using System.Web.UI.WebControls;
10.  Change the base class of EcmaScriptDelegateControl to WebControl by modifying the following line.
class EcmaScriptDelegateControl : WebControl

11.  Override the OnLoad method by adding the following code.

protected override void OnLoad(EventArgs e)
{
  base.OnLoad(e);
}

12.  Inside the OnLoad method, add the following code to put JavaScript on the page.

string helloAlert = "alert('Hello, world!');";
this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "popup", helloAlert, true);

Now, you have built the delegate control for the project. Next, you will create the Feature to deploy the control.
To create a Feature to deploy the control
1.      In the Solution Explorer, right-click the EcmaScriptDelegate project and select Add and then New Item.
2.      In the Add New Item dialog box, choose the Empty Element template and type EcmaScriptDelegateFeature as the Name. Click Add.
3.      Insert the following XML inside the Elements element. The Id attribute identifies the delegate where the control is rendered. The ControlAssembly and ControlClass attributes are unique to your control. For more information about how to find the full assembly name, see How to: Create a Tool to Get the Full Name of an Assembly.


The most flexible thing about the delegate control is that it can be defined at the 4 scopes:

·         Web
·         Site collection
·         Web application
·         Farm

Thus, I can set the feature of this scope to activate at any level, and have it immediately show up in ALL of my pages.

The best part is, when you deactivate the feature, it is completely gone and has no impact! No messing with the master page!

JavaScript to add a global link near Site Actions menu in SharePoint 2010

The goal is to add a link next to the Site Actions menu that would always lead back to the portal home, similar to below.




Using IE Developer Tools, I was able to determine the location where I wanted to place my link was inside of the RibbonContainer-TabRowLeft element.

You can modify the master page and inject the following javascript to achieve this:

Read my following post to see how to make this work on all site collections across a web application by using a delegate control!




ExecuteOrDelayUntilScriptLoaded(ExecuteDefaultLoad, "sp.js");

function ExecuteDefaultLoad()
{

 var isWikiEdit = false;
 if ( document.forms[MSOWebPartPageFormName]._wikiPageMode != null )
 {
  if( document.forms[MSOWebPartPageFormName]._wikiPageMode.value == "Edit" )
    {
     isWikiEdit = true;
    }
  }

 var inDesignMode = document.forms[MSOWebPartPageFormName].MSOLayout_InDesignMode.value;
 if (inDesignMode == "1" || isWikiEdit) 
 {  
  // this page is currently in edit mode 
 } 
 else 
 {  
  AddHomeLink();
 } 
}


function AddHomeLink()
{
 var ribbonContainerRowLeft = document.getElementById("RibbonContainer-TabRowLeft");
 if( ribbonContainerRowLeft != null )
 {
  if( ribbonContainerRowLeft.children != null && ribbonContainerRowLeft.children[0] != null )
  {  
  var newSpan = document.createElement("span");
  newSpan.innerHTML='<a class="ms-menu-a" style="cursor:pointer;white-space:nowrap;"    href="javascript:;" title="SharePoint Portal Home" onclick="window.location=\'/\';return false;"><img src="/_layouts/images/hhome.png"  border="0px"/></a>';
  newSpan.className = 'ms-SPLink ms-SpLinkButtonInActive ms-welcomeMenu';
  newSpan.onmouseover= function() {  this.className = "ms-SPLink ms-SpLinkButtonActive ms-welcomeMenu"}; 
  newSpan.onmouseout= function() {  this.className = "ms-SPLink ms-SpLinkButtonInActive ms-welcomeMenu"}; 
  ribbonContainerRowLeft.insertBefore(newSpan, ribbonContainerRowLeft.children[0]);
  }
 }
}

Display SharePoint List Item Attachments as Images

Suppose you want a visual display of the images that you attach to a SharePoint list. Clicking on each attachment to open it can be a hassle instead of just having it automatically display the images on load.


By default, the attachments are listed as links:




If you view the properties of a SharePoint list item, you will see that the link to each attachment is calculated by: 

[Site Url]/Attachments/[Item ID]/[Attachment Name]

So, if we can grab the item id of the list item, and then determine the attachment names, we will be able to use those properties to display the image with an img tag.

First thing's first. If you view the source of that default SharePoint item view page, you will see that the attachments are store din the element: idAttachmentsTable. We want to grab all of the attachment names in that element. To do so, we will iterate through the span elements and parse out the attachments:  


 

<script type="text/javascript">
spanTag = document.getElementById("idAttachmentsTable").getElementsByTagName("span");
var attachmentArray = new Array();
for (var i = 0; i < spanTag.length; i++) 
{
  filename = spanTag[i].innerHTML;
  var index  = filename.indexOf('>')+1;
  var lastindex = filename.lastIndexOf('<');

  var name = filename.substring(index, lastindex);

  name = name.replace(/ /g, '%20');
  name = name.replace(/'/g, '%27');

  for( var x = 0; x < imgExtensions.length; x++ )
  {
   if( name.indexOf(imgExtensions[x]) >=0 )
   {
    attachmentArray.push([name]);
    break;
   }
  }
}
</script>

Now that we have the names of the attachments, we want to grab the current item id of our list item, which we can simply grab from the source url.

Call to get the item ID:

var paramID = getParameterByName("ID");

Function to grab the parameter from the source url:
function getParameterByName(name) 
{   
 name = name.replace(/[\[]/, "
\\\[").replace(/[\]]/, "\\\]");  
 var regexS = "[\\?&]" + name + "=([^&#]*)"; 
 var regex = new RegExp(regexS);  
 var results = regex.exec(window.location.href); 
 if(results == null) 
  return "";
 else   
  return decodeURIComponent(results[1].replace(/\+/g, " "));
}

Now, we will use the paramID and the attachment names to create our img tags and append it to the Attachments element:

var ctrl = document.getElementById("idAttachmentsTable");
 var attachmentString = "";
 for( i = 0; i < attachmentArray.length; i++)
 {
  attachmentString += 
  " <img src='" + listAttachmentUrl + paramID + "/"+ attachmentArray[i] + "' width='400px' border='2'>";
 }
 ctrl.parentNode.innerHTML += attachmentString;


After adding our script:





To use this script, you will need to use SharePoint designer to edit the "View" page of the list. Navigate to the end of the PlaceHolderMain content placeholder, and right before the closing "</asp:Content>" tag, place the script below in it's entirety. Make sure to modify the listAttachmentUrl to reflect your site and list names:

<script language="javascript" type="text/javascript"> 
var listAttachmentUrl = '/mysite/Lists/mylist/Attachments/';
var imgExtensions = new Array(".jpg",".jpeg", ".png", ".bmp", ".tif", ".tiff");
LoadAllAttachments();

function LoadAllAttachments()
{
 spanTag = document.getElementById("idAttachmentsTable").getElementsByTagName("span");
 var attachmentArray = new Array();
 for (var i = 0; i < spanTag.length; i++) 
 {
  filename = spanTag[i].innerHTML;
  var index  = filename.indexOf('>')+1;
  var lastindex = filename.lastIndexOf('<');

  var name = filename.substring(index, lastindex);

  name = name.replace(/ /g, '%20');
  name = name.replace(/'/g, '%27');
  for( var x = 0; x < imgExtensions.length; x++ )
  {
   if( name.indexOf(imgExtensions[x]) >=0 )
   {
    attachmentArray.push([name]);
    break;
   }
  }
 }

 var paramID = getParameterByName("ID");
 var ctrl = document.getElementById("idAttachmentsTable");
 var attachmentString = "";
 for( i = 0; i < attachmentArray.length; i++)
 {
  attachmentString += 
  " <img src='" + listAttachmentUrl + paramID + "/"+ attachmentArray[i] + "' width='400px' border='2'>";
 }
 ctrl.parentNode.innerHTML += attachmentString;
}

function getParameterByName(name) 
{   
 name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");   
 var regexS = "[\\?&]" + name + "=([^&#]*)";  
 var regex = new RegExp(regexS);   
 var results = regex.exec(window.location.href);  
 if(results == null)  
  return ""; 
 else    
  return decodeURIComponent(results[1].replace(/\+/g, " "));} 
</script>

SharePoint Color Coded list based on a Field in the Row

SharePoint doesn't provide an out of the box way of color coding lists. But, thank goodness, we can use a little scripting to edit the styling of our lists!

Mike Smith provided a great script that allows you to color the background of the row if the cell's value matches the value it's looking for. But, what if another field in the same row has one of the other values and throws off your color coding?

Case in point: color coding is thrown off because the Description field
can have the same value that is being used to color code on
  

Well, this script below will search only the cell index of the row that you would like to base your color coding on. In our case, we would like to search only on the Status field/column. To get started:

1. Add a content editor web part directly underneath the list
2. Open the source editor and place the script below into it
3. Modify the columnIndexToSearch and the columnSpan variables to match the cell/field index to search for and the number of cells in each row respectively.

Note: In this case, the attachment field counts as a cell. Since we are searching only on the Status, our columnIndexToSearch is 2 (0 = Attachment field and 1 = Title field). The total number of columns we are displaying on our list is 5. If you add or remove columns in the view, the color coding will get thrown off. So, make sure to update these variables if you do make updates to the list view.

Final Result: Color coded based on the Status column only
   







<script type="text/javascript">


var listView = getElementsByClass("ms-listviewtable"); //get the list on the page
var tRows = listView[0].childNodes[0].childNodes;

var columnIndexToSearch = 2; //the index of the column that should be searched
var columnSpan = 5; //number of columns visible on the list

var j = 0;
var i = 0; 
var cellcounter = 0; //used to keep track of the cells searched on the row

for( j = 0; j < tRows.length; j++)
{
 if( tRows[j].className == "" || tRows[j].className == "ms-alternating")
 {
  var x = tRows[j].childNodes; // find all of the TRs
  for (i = 0; i < x.length; i++) 
  { 
   if( cellcounter == columnIndexToSearch) 
   {
    if (x[i].innerHTML.indexOf("In Progress") >= 0)
    { 
     x[i].parentNode.style.backgroundColor='lightgreen'; 
    }

    else if (x[i].innerHTML.indexOf("Completed") >= 0)
    { 
     x[i].parentNode.style.backgroundColor='lightblue'; 
    }

    else if (x[i].innerHTML.indexOf("Deferred") >= 0)
    { 
     x[i].parentNode.style.backgroundColor='lightgrey'; 
    }

    else if (x[i].innerHTML.indexOf("Waiting on someone else") >= 0)
    { 
     x[i].parentNode.style.backgroundColor='orange'; 
    }
  }

   cellcounter++;
   if( cellcounter >= columnSpan)
   {
    cellcounter = 0;
   }
  } 
 }
}

function getElementsByClass(searchClass, node, tag) 
{
 var classElements = new Array();
 if ( node == null )
  node = document;
 if ( tag == null )
  tag = '*';
 var els = node.getElementsByTagName(tag);
 var elsLen = els.length;
 var pattern = new RegExp("(^|\\s)"+searchClass+"(\\s|$)");
 for (i = 0, j = 0; i < elsLen; i++) 
 {
  if ( pattern.test(els[i].className) ) 
  {
   classElements[j] = els[i];
   j++;
  }
 }
 return classElements;
}

SharePoint Calendar Jump to Next or Previous Month

I had a SharePoint calendar and I wanted a way to jump to the Next or Previous month from the left hand navigation/quick launch menu. 

I couldn't hardcode this url into the navigation, because it would change every month. I needed a dynamic way to do this. To address this, I created a new blank SharePoint page in my site, called "MonthRedirector". I added a script that would determine the current month, and then either skip to the next or previous month based on the query string parameters passed in.


1. Create a blank SharePoint page, call it MonthRedirector
2. Add a content editor web part to the page and paste in the script below or (View Code)

Make sure to set the "Chrome Type" to be "none" and modify the site url in the script to reflect your site's url

3. Add 2 new links to the Navigation menu, 1 for the previous month and 1 for the next month:

[siteurl]/Pages/MonthRedirector.aspx?Jump=Prev&Calendar=[Your calendar name]

[siteurl]/Pages/MonthRedirector.aspx?Jump=Next&Calendar=[Your calendar name]


Now, when a user clicks on the links on the left hand navigation, it will automatically direct them to the previous month or the next month on the calendar!


 
<style>
#sidebar,#sidebar-footer {display : none !important;}
</style>

<script type="text/javascript">
var siteURL = "http://mySiteUrl";
//if you do not wish to hardcode the name, use something
//like SPServices to grab the current site url
//var siteURL = $().SPServices.SPGetCurrentSite();

var curDate = new Date();
var paramfilterJump = getParameterByName("Jump");
var paramCalendarName = getParameterByName("Calendar");

if( paramCalendarName != null && paramCalendarName !="" && paramfilterJump != null 
 && paramfilterJump != "" && paramfilterJump == "Next")
{
 var fullDateString =  PadDigits(curDate.getMonth() + 2, 2)  + "%2F" + PadDigits(curDate.getDate(), 2) + "%2F" +  curDate.getFullYear();  
 var redirectURL = siteURL + "/Lists/" + paramCalendarName + "/calendar.aspx?CalendarDate=" + fullDateString; 
 window.location.href = redirectURL;
}
else if( paramCalendarName != null && paramCalendarName != "" && paramfilterJump != null 
 && paramfilterJump != "" && paramfilterJump == "Prev")
{
 var fullDateString =  PadDigits(curDate.getMonth(), 2)  + "%2F" + PadDigits(curDate.getDate(), 2) + "%2F" +  curDate.getFullYear();  
 var redirectURL = siteURL + "/Lists/" + paramCalendarName + "/calendar.aspx?CalendarDate=" + fullDateString; 
 window.location.href = redirectURL;
}

function PadDigits(n, totalDigits) 
{ 
 n = n.toString(); 
 var pd = ''; 
 if (totalDigits > n.length) 
 { 
  for (i=0; i < (totalDigits-n.length); i++) 
  { 
   pd += '0'; 
  } 
 } 
 return pd + n.toString(); 
} 

function getParameterByName(name) {   name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");   var regexS = "[\\?&]" + name + "=([^&#]*)";   var regex = new RegExp(regexS);   var results = regex.exec(window.location.href);   if(results == null)     return "";   else     return decodeURIComponent(results[1].replace(/\+/g, " ")); } 

</script>
