JavaScript / jQuery on the page at either:
- $(document).ready
- _spBodyOnLoadFunctionNames
will not return the required result, since the menu elements we need to interrogate have not been rendered yet.
Solution:
- Set a timer to keep running a particular function to wait until the menu is rendered
- Stop the timer
- Interrogate the DOM as required using jQuery
Code Example:
<script type='text/javascript'>
var timerHandle ="";
var currentWindowsAccount="";
_spBodyOnLoadFunctionNames.push("runCustom");
function runCustom() {
timerHandle = setTimeout(getCurrentLoggedInUser, 10;
}
function getCurrentLoggedInUser() {
//Function requires jQuery
/* Retrieve the current logged in user from the My Profile option in **
** the Welcome Menu (id=ID_MySiteLinksMenu) **
** This needs a timeout to wait for the menu to be rendered via AJAX */
//Timers are expensive on client resources, clear at all opportunities
clearTimeout(timerHandle);
var welcomeMenuItems =$('#ID_MySiteLinksMenu'); //ie:menu with id='ID_MySiteLinksMenu'
if(welcomeMenuItems.length>0) {
var onmenuclickValue = welcomeMenuItems.attr("onmenuclick");
var onmenuclicksplit = onmenuclickValue.split("=");
var loggedInUserString = onmenuclicksplit[1];
var loggedInUserStringSplit = loggedInUserString.split("'");
currentWindowsAccount = loggedInUserStringSplit[0];
alert(currentWindowsAccount);
}
else{
//My Profile link has not been rendered yet, try again.
timerHandle = setTimeout(getCurrentLoggedInUser, 10);
}
}
</script>
