Resolve people picker before presave

Question

I have a function in presave that takes the user name in the people picker available on the form and do some business logic. After completion of script the actual save function is called.

The issue is that if the value entered in people picker is not resolved (even if the value is valid name) then the value is not received correctly in the presave function.

I have tried to call the click of people picker resolution but since its asynchronous function i cannot get the entire value ie. domain/alias before my further code starts executing.

Any idea on how to achieve this.

Answer 1

In order to check (on the client side) if the value entered in people picker is resolved the following function could be used

//Determines If People Picker value is resolved (using jQuery)
function IsPeoplePickerValueResolved() { 
   var eEntityData = $("div[id='divEntityData']");
   if(eEntityData.length > 0 ) {
       var isResolved = eEntityData.attr("isresolved");
       return (isResolved == "True"); 
   }    
   return false;
}

Usage

function PreSaveAction() { 
   var isResolvedUser = IsPeoplePickerValueResolved();
   //...   
   return true;
}

For example,

returns false

---

returns true

Answer 2

You could try using the SPServices library to get a handle on the field and initiate a name resolution through JavaScript. In specific, take a look at the SPFindPeoplePicker function:

$().SPServices.SPFindPeoplePicker

Take a look at the checkNames section:

checkNames

This is a reference to the checkNames img tag in the People Picker. It’s used by the function to initiate resolution of a Person or Group value by firing the click event on it. Once you have this reference, you can do the same.

You could probably also figure out how to do this on your own without the use of SPServices. Just get a handle on the image and initiate a click().

Answer 3

$().SPServices.SPFindPeoplePicker does not work. The method is not supported on a person/group field.
