I get the error :
Object doesn't support property or method 'set_formDigestHandlingEnabled'
when I try to get the current SPContext object from javascript code in an Office 365 site.
I am using a script editor web part and getting the context to do further operations
var cntxt;
.
.
.
cntxt = SP.ClientContext.get_current()
Has anyone faced this before?
Based on comments to the original question, the way in which the scripts are loaded on your page must be preventing SharePoint from initializing all of the standard JavaScript items on the page. Add your custom scripts one by one, and remember that you may need to use jQuery.ready, SP.SOD.ExecuteOrDelayUntilScriptLoaded(<yourscript>, "SP.js") // or sp.ui, or sp.core, or something else, but usually SP.js is sufficient, or some other similar technique to make sure SharePoint has initialized its environment before you load your custom script.
I had the same error message in a html without SharePoint Server rendering. For me I mixed up the load sequence of the sp.runtime.js and sp.js. You have to load the sp.runtime.js before the sp.js
<head>
...
<script src="//ajax.aspnetcdn.com/ajax/4.0/1/MicrosoftAjax.js"></script>
<script src="/_layouts/15/sp.runtime.js"></script>
<script src="/_layouts/15/sp.js"></script>
...
</head>
Using 'new' is definitely required, as suggested by wjervis: var context = new SP.ClientContext(currentUrl);
You need to use ExecuteOrDelayUntilScriptLoaded function :
ExecuteOrDelayUntilScriptLoaded(internalOpenDialog, "SP.JS");
function internalOpenDialog(){
......
//code
....
}
cntxt = new SP.ClientContext(currentUrl);?
