How to select radio buttons in jquery
<p>The code below adds a value into a textbox:</p>

<pre><code>$('#mainTxtWeight').val(textWeight);
</code></pre>

<p>But what I want know is how can I select a radio button depending on what a value is using jquery?</p>

<p>Below is the radio buttons:</p>

<pre><code>&lt;table id="replies"&gt;
    &lt;tr&gt;
        &lt;th colspan="2"&gt;Replies&lt;/th&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
        &lt;td&gt;Number of Replies:&lt;/td&gt;
        &lt;td align="left"&gt;
            &lt;div class="replytd"&gt;
                &lt;label&gt;
                    &lt;input type="radio" name="reply" id="singlebtn " value="single" class="replyBtn"
                    /&gt;Single&lt;/label&gt;
            &lt;/div&gt;
            &lt;div class="replytd"&gt;
                &lt;label&gt;
                    &lt;input type="radio" name="reply" id="multiplebtn" value="multiple" class="replyBtn"
                    /&gt;Multiple&lt;/label&gt;
            &lt;/div&gt;
        &lt;/td&gt;
    &lt;/tr&gt;
&lt;/table&gt;
</code></pre>

<p>I have created an if statement below, I just need help being able to select "Single" radio button if Reply Type equals "Single", or select "Multiple" radio button if reply Type equals "Multiple".</p>

<p>Below is if statement:</p>

<pre><code>if(reply == "Single") {
    //select "Single" radio button
} else if(reply == "Multiple") {
    //select "Multiple" radio button
}
</code></pre>

<p>I want the exact same thing to occur with this line of code as well which is again "Single" and "Multiple" radio buttons:</p>

<pre><code>var $btnReply = "&lt;input type='radio' name='reply[" + count + "]' value='single' class='replyBtnRow' /&gt; Single&lt;br /&gt;&lt;input type='radio' name='reply[" + count + "]' value='multiple' class='replyBtnRow' /&gt; Multiple";

$replies.children().append($btnReply);

if($("input[name=reply]:checked").length) {
    $replies.find('input[name="reply[' + count + ']"]').eq($("input[name=reply]:checked").val() == "single" ? 0 : 1).prop("checked", true);
}
</code></pre>

<p>UPDATE:</p>

<pre><code>function addwindow(reply) { 


    if($(plusbutton_clicked).attr('id')=='mainPlusbutton') { 

        $('input[value="'+reply.toLowerCase()+'"]').attr('checked', true);
        } else { 
            $(plusbutton_clicked).closest('tr').find('input[value="'+reply.toLowerCase()+'"]').attr('checked', true);
            }

    $.modal.close(); 
    return false;
} 
</code></pre>
