Question

I have multiple selects and would like to add or remove a name attribute depending on the option that is chosen in the first select.

Here is a fiddle for an example:

Answer 1

You just had a few things backwards and you forgot the ‘.’ in the class selector: $('.class'). I fixed the fiddle: http://jsfiddle.net/DZFFe/7/

$("#mySelect").change(function() {
    $(".selectorClass").removeAttr("name");
    var x = document.getElementById("mySelect").value;
    if($("#" + x)) {
        $("#" + x).attr("name", "myName");
    }
});
