Question

I want to get multiple radio buttons value using Jquery. But now could only get the first one’s value.

<form action="get" method="post">
                    <table width="100%">
                    <tbody id="checklistwrapper">

                    <tr class="checklisttr" id="1">

                    <td align="left" width="40%"><br>
                    <label for="veryiii" style="align:left;">Within your circle of competence?</label>
                    </td>

                    <td align="center">
                    <label for="veryi" width="12%">Worst</label><br><br>
                    <input type="radio" id="veryi" value="5.0" name="circle">
                    </td>

                    <td align="center" width="12%"><br><br>
                    <input type="radio" id="vii" value="4.5" name="circle">

$('#savechecklist').click(function() {
    var the_value;
    //the_value = jQuery('input:radio:checked').val();
    //the_value = jQuery('input[name=macro]:radio:checked').val();
    the_value = getChecklistItems();
    alert(the_value);
});

function getChecklistItems() {
    var result =
        $("tr.checklisttr > td > input:radio:checked").get();

    var columns = $.map(result, function(element) {
        return $(element).attr("id");
    });

    return columns.join("|");
}
