Check if a radio button is checked jquery
<p>Sorry for being a noob, I am still learning :)</p>

<p>I have this HTML:</p>

<pre><code>&lt;input type="radio" name="test" id="test" value="1"&gt;&lt;br&gt;
&lt;input type="radio" name="test" id="test" value="2"&gt;&lt;br&gt;
&lt;input type="radio" name="test" id="test" value="3"&gt;&lt;br&gt;

&lt;input type="button" onclick="CreateJobDo"&gt;
</code></pre>

<p>When the page loads, none of them will be checked. I want to use Jquery to check if one of the radio buttons is checked when the button is pressed...</p>

<p>I have this:</p>

<pre><code>function CreateJobDo(){
 if ($("input[@name=test]:checked").val() == 'undefined'){
    // go on with script


 }else{

    // NOTHING IS CHECKED
 }


}
</code></pre>

<p>But this does not work. How to get it working?</p>
