spBodyOnLoadFunctionNames not working on Master Page

Question

we are trying to execute some script after the master page loads.

 <script language="javascript">  
        _spBodyOnLoadFunctionNames.push("FunctionName");   
        function FunctionName()   
        {   
           alert('test');
        }   
    </script>  
</head>

We are not getting the alert. Any thing missing here? Tried to debug in IE, the debugger does not get hit. Why is this?

Answer 1

You need init.js loaded before _spBodyOnLoadFunctionNames can work, make sure its loaded before running your script. _spBodyOnLoadFunctionNames is an array, that are execute in the ProcessOnLoadFunctionNames function. The ProcessOnLoadFunctionNames is executed in the ProcessDefaultOnLoad function. The ProcessDefaultOnLoad is execute with: ExecuteOrDelayUntilScriptLoaded(ProcessDefaultOnLoad, "core.js");

You could also use ExecuteOrDelayUntilBodyLoaded(FunctionName()); or ExecuteOrDelayUntilScriptLoaded(FunctionName, "core.js");

Answer 2

Instead of at the top in the head, put it in a script tag at the bottom of the page.
