I am using the following jquery/function to bring the focus back into a text box if the proper number isn't returned. It works fine in IE but in Firefox the &quot;focus&quot; doesn't work. It allows the user to move to the next field after displaying the error. Can someone assist?<br />
<br />

<pre><code id="code-10-28686608-1">function CheckTheNum(ID) {
    var cfcAsAjax = new jsobj();
    x = cfcAsAjax.CheckTheNum(ID);
    if (x == true) {
        //    document.getElementById('labelNum').innerHTML = '&lt;span&gt;Number:&lt;/span&gt;';
        jQuery(&quot;#labelNum&quot;).html(&quot;&lt;span&gt;Number:&lt;/span&gt;&quot;);
    } else {
        jQuery(&quot;#labelNum&quot;).html(&quot;&lt;span&gt;The Number:&lt;/span&gt;&lt;br /&gt;&lt;span class='red'&gt;&lt;strong&gt;Please enter a valid number&lt;/strong&gt;&lt;/span&gt;&quot;);

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
