How to check a set of radio buttons that all are selected?
<p>I've a list of radio buttons that are generated dynamically. The names of radio buttons are also generated dynamically. The first row of radio buttons has name 1, the second row radio buttons have name 2. Each row has three radio buttons with same name but different values.</p>

<p>How can I check using jquery that one radio button is selected in each row when submitting the form?</p>

<pre><code>&lt;tr&gt;
                            &lt;th&gt;1&lt;/th&gt;
                            &lt;td&gt; Please select one option &lt;/td&gt;
                            &lt;td class='selectable_cell'&gt;
                            &lt;input type="radio" name="2" value="1" /&gt;
                            &lt;/td&gt;
                            &lt;td class='selectable_cell'&gt;
                            &lt;input type="radio" name="2" value="2" /&gt;
                            &lt;/td&gt;
                            &lt;td class='selectable_cell'&gt;
                            &lt;input type="radio" name="2" value="3" /&gt;
                            &lt;/td&gt;
                        &lt;/tr&gt;
&lt;tr&gt;
                            &lt;th&gt;2&lt;/th&gt;
                            &lt;td&gt; Please select another option &lt;/td&gt;
