Getting "Uncaught TypeError: Cannot read properties of undefined (reading 'href')" error on SharePoint 2010 form load

Question

When opening a SharePoint 2010 form in modal mode I get the following error:

Uncaught TypeError: Cannot read properties of undefined (reading 'href')

See code below for usage and troubleshooting.

$(document).ready(function () { ExecuteOrDelayUntilScriptLoaded(OnLoad, "sp.js"); function OnLoad() { var id = GetUrlKeyValue("ID", false, location.href); <== Error createCookie("Parent", id); // Create cookie } // End onload }); // End document ready 

I'm not sure what happened yesterday, but this has been working for years in other projects in SP, but for this particular project just popped up this error.

Answer 1

Use window.location.href instead of location.href like:

$(document).ready(function () { ExecuteOrDelayUntilScriptLoaded(OnLoad, "sp.js"); function OnLoad() { var id = GetUrlKeyValue("ID", false, window.location.href); createCookie("Parent", id); // Create cookie } // End onload }); // End document ready
