Question

The code below adds a value into a textbox:

$('#mainTxtWeight').val(textWeight);

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

Below is the radio buttons:

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

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”.

Below is if statement:

if(reply == "Single") {
    //select "Single" radio button
} else if(reply == "Multiple") {
    //select "Multiple" radio button
}

I want the exact same thing to occur with this line of code as well which is again “Single” and “Multiple” radio buttons:

var $btnReply = "<input type='radio' name='reply[" + count + "]' value='single' class='replyBtnRow' /> Single<br /><input type='radio' name='reply[" + count + "]' value='multiple' class='replyBtnRow' /> 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);
}

UPDATE:

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;
}

If you are trying to get the radio button which has a value of what’s in reply, which if I understand your question correctly, you can try this

$('input[value="'+reply.toLowerCase()+'"]')​.attr('checked', true)

assuming reply will always be ‘single’ or ‘multiple’
