Question

This is an easy bit of coding, but something’s there that i am doing wrong.I just can’t figure it out.

#div {
    display:none;
}

JS:

function show() {
    var class = 1;
    $("#div." + class).show("slow");    
}

HTML:

<div id="div" class="1">John</div>
<div id="div" class="2">Tanner</div>
<input type="button" onclick="show()" />

Here I am trying to ‘show()’ a div of specific class.
The problem is, this code works fine for class="1". But when I change var class to 2, it stops working.

Answer 1

A class can’t be just a number. Rename the class to $("#div." + "name"+class)
