Question

    var x = document.getElementById("testingAjax");
    if (x != null) {
        var left = x.position().left;
        alert(left);
    }

why is the above code breaking? It is breaking on var left = x.position().left with the error Object doesn’t support this property or method;

Answer 1

If you are using jQuery, you need to wrap any non jQuery object in $(..). So your code becomes:

var x = document.getElementById("testingAjax");
if (x != null) {
    var left = $(x).position().left; // x by itself is not a jQuery object. Need to pass it to $(..)
    alert(left);
}
