Question

I have a table like so:

    <table>
        <tr>
            <td>
                <input type="radio" name="Sample1" id="Sample1" value="1" />
                <input type="radio" name="Sample1" id="Sample2" value="1" />
            </td>
            <td>
                <input type="radio" name="Sample2" id="Sample1" value="1" />
                <input type="radio" name="Sample2" id="Sample2" value="1" />
            </td>
            etc....
        </tr>
    </table>

I want to be able to select a specific radio button by name and id. E.G., select the radio button with the name Sample2 and id Sample1. I tried doing this:

    $('[id="Sample1"][name="Sample2"]').checked = true;

But no luck… How should I be doing this?

Answer 1

 $('#Sample1[name="Sample2"]').attr('checked','checked');

but elements can only have one id so maybe you want class instead of id

  $('.Sample1[name="Sample2"]').attr('checked','checked');

then your html

<table>
    <tr>
        <td>
            <input type="radio" name="Sample1" class="Sample" value="1" />
            <input type="radio" name="Sample1" class="Sample" value="1" />
        </td>
        <td>
            <input type="radio" name="Sample2" class="Sample1" value="1" />
            <input type="radio" name="Sample2" class="Sample2" value="1" />
        </td>
    </tr>
</table>

EDIT

made some changes here is a working demo
