ExecuteOrDelayUntilScriptLoaded not executing after page publish

Question

In SharePoint 2013 I have a page that is using the Script Editor web part.
In the script editor web part I have the following:

ExecuteOrDelayUntilScriptLoaded(startIt, "sp.js");

function startIt() {
alert('Started');
}

How come the alert is called when the page is unpublished, but once I publish the page then ExecuteOrDelayUntilScriptLoaded() is not firing. I'm using IE.

Is this a possible bug?

Answer 1

Here is my fix to the problem.

It seems in SP 2013 calling ExecuteOrDelayUntilScriptLoaded() doesnt work on published pages.

In SP2013 this is the correct way to do it according to MS @ http://msdn.microsoft.com/en-us/library/jj245759.aspx

// Make sure the SharePoint script file 'sp.js' is loaded before your // code runs.

SP.SOD.executeFunc('sp.js', 'SP.ClientContext', startIt);

As a part of the new Minimal Download Strategy (MDS), sp.js is not loaded by default on published pages.

You will have to load your sp.js explicitly from the /_layouts/15 directory. Example (not tested):

$(document).ready(function(){

   var fileUrl = _spPageContextInfo.webAbsoluteUrl + "/_layouts/15/sp.js";

   $.getScript(fileUrl,function(){

        alert('Started');

    });

});

This change from SharePoint 2010 makes sense in a way that you should only load the sp.js file if you want to make use of the JavaScript Client Object Model. If you are going to use the REST API, you will not need the sp.js file.
