Why is SP.js not loading?

Question

I have researched this pretty thoroughly and everyone says that the code I have below should load SP.js, but I cannot get it to load.

Debugging I get:

NewForm.aspx, line 1667 character 5
SCRIPT5009: 'PeoplePicker' is undefined 

and do not see SP.JS under view sources.

<SharePoint:ScriptLink Name="SP.js" runat="server" OnDemand="true" 
    Localizable="false" /> 
<script type="text/javascript">

ExecuteOrDelayUntilScriptLoaded(SetWebUserData(), "SP.js");

function SetWebUserData() {
    var pplPicker = new PeoplePicker();
    // Set the parent tag id of the people the picker.
    pplPicker.SetParentTagId('Main_x0020_Contact');
    pplPicker.SetLoggedInUser();
    };
</script>

Any assistance greatly appreciated.

Answer 1

I was able to resolve the issue and have people picker populated with the current user by using code found here: http://vbcity.com/blogs/skullcrusher/archive/2008/11/04/set-sharepoint-peoplepicker-field-mark-2.aspx

This code does not require SP.js

I was never able to get sp.js to load properly, but this solution fixes my problem.

You are using ExecuteOrDelayUntilScriptLoaded wrong. You should only pass the function name, it should look like this:

ExecuteOrDelayUntilScriptLoaded(SetWebUserData, "sp.js");

Without the ()

Answer 3

The first parameter of ExecuteOrDelayUntilScriptLoaded has to be a function. This function is called after the requested script file has been loaded.

<SharePoint:ScriptLink Name="SP.js" runat="server" OnDemand="true" 
    Localizable="false" /> 
<script type="text/javascript">

ExecuteOrDelayUntilScriptLoaded(SetWebUserData, "SP.js");

function SetWebUserData() {
    var pplPicker = new PeoplePicker();
    // Set the parent tag id of the people the picker.
    pplPicker.SetParentTagId('Main_x0020_Contact');
    pplPicker.SetLoggedInUser();
    };
</script>

With (), you call a function. This means, your error was to pass the result of your function as parameter, not the function itself.

Example for better understanding:

function helloFunction() {
    return 42;
}

var myHelloFunction = helloFunction; // Function is passed
var myHelloFunctionResult = helloFunction(); // Result of your function (42) is passed

Answer 4

I know that it is a little late, but I think this is the answer you are looking for.

SP.SOD.executeFunc('sp.js', 'SP.ClientContext',function(){
  var pplPicker = new PeoplePicker();
  // Set the parent tag id of the people the picker.
  pplPicker.SetParentTagId('Main_x0020_Contact');
  pplPicker.SetLoggedInUser();
};
