Javascript fails to access a JSF component by calling through its id

It does not work when I try to retrieve an element using jQuery(idOfElement) when I use a variable but works fine if I use something like this: jQuery('#e') . How can I make it work correctly by passing a variable parameter ?

I am trying out the following piece of code:

function calculatePosition(idOfElement){
        var $element = jQuery(idOfElement);
        var offset = $element.offset();
        var x = offset.left;
        var y = offset.top;
        ....
        ....
    }

Assuming you’re passing in the id as a string like this:

calculatePosition("randomID");

Then you need to add the # at the start of the jQuery selector:

var $element = jQuery("#" + idOfElement);
