I'm learning to write SharePoint 2013 applications. I added menu item custom action, and now I'm trying to add some functionality to App.js. Custom action contains the following code:

<UrlAction Url="~appWebUrl/Pages/Default.aspx?{StandardTokens}&amp;SPListItemId={ItemId}&amp;SPListId={ListId}" />

And I'm trying to get parameters like "SPListItemId" and "SPListId" in App.js. I found the following code:

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

I'm calling this function like, but it doesn't work: 

var SPListId = getParameterByName('ListId');

Please tell me where is my mistake.

You need to use

var SPListId = getParameterByName('SPListId');

  • Hey Kai. Thank you for answer. But the problem is still there. Function getParameterByName(name) uses only location.search, maby it should get data from the document? Or how to use getParameterByName('SPListId'); correctly? Commented Nov 11, 2016 at 14:12
  • You're right, it uses location.search, in other words it tries to get parameter value from you query string. For example for following url http://my.app.com/?SPListId=4 the function will return 4. If SPListId is missing from query string, it returns nothing. Commented Nov 11, 2016 at 14:24
  • When application has started, the document is loaded too. I got the applications url through the document, but there is no tag with ListId. From what object I can retrieve any staff to use getParameterByName? Commented Nov 11, 2016 at 15:04
  • Which List Id are you expecting on Pages/Default.aspx? Commented Nov 11, 2016 at 15:05
  • My action begins when the button in list item menu is activated. After that, the application is loaded on Default.aspx. I wanna get ItemId and ListId, where the application was called. I thought that this information can be obtained from a string <UrlAction Url="~appWebUrl/Pages/Default.aspx?{StandardTokens}&amp;SPListItemId={ItemId}&amp;SPListId={ListId}" /> by using JS script in App.js Commented Nov 11, 2016 at 15:15
