Using a variable for getElementById
<p>I have a checkbox that is being echoed by PHP. So, the id of the checkbox will be dynamic.</p>

<p>So, I would like use a variable for <code>document.getElementById()</code>.</p>

<p>Below is my PHP code:</p>

<pre><code>echo "&lt;td&gt;&lt;input type='checkbox' name='edit$count' value='1' onclick='test($count)'&gt;&lt;/td&gt;";
</code></pre>

<p>Then here is my Javascript code</p>

<pre><code>function test(v)
    {
        var edit = "edit" + v;


        if(document.getElementById(edit).checked==true){
            alert(edit);
        }
    }
</code></pre>

<p>However, when I clicked on the checkbox, there is no alert. </p>

<p>Is there something wrong with my code?</p>
