Question

I have some radio buttons with different numeric values. How to apply autoselect option on which radio button value is smaller that other radio button values.

Ex:

            <table class="tbl">
                    <tr>
                        <td><input type="radio" name="" value="15" /></td>
                    </tr>
                    <tr>
                        <td><input type="radio" name="" value="45" /></td>
                    </tr>
                    <tr>
                        <td><input type="radio" name="" value="10" /></td>
                    </tr>
                    <tr>
                        <td><input type="radio" name="" value="12" /></td>
                    </tr>
                    <tr>
                        <td><input type="radio" name="" value="25" /></td>
                    </tr>
            </table>

This might be solved without each. Just find index of min value and select this radio button on this index like below.

var radios = $(".tbl input:radio");
var vals = radios.map(function(index, el) { return parseInt($(el).val()); }).get();
var index = $.inArray(Math.min.apply(null, vals), vals);

radios.eq(index).attr("checked", "checked");
