Jquery radio的name值不一样，只能选中一个

<input id="Is[0]" value="0" name="Is[0]" type="radio">

<input id="Is[1]" value="0" name="Is[1]" type="radio">

<input id="Is[2]]" value="0" name="Is[2]" type="radio">

<script type="text/javascript">
 $(document).ready(function(){
    $("input:radio").click(function(e){
           var tag = e.srcElement || e.target;
            $("input:radio").val('0').removeAttr("checked");
            $(this).val('1').attr("checked", "true");
    })
 });
</script>
