jquery - 遍历复选框并确定是否选中

Question

我想遍历复选框 div 并确定是否选中了 checkbox1、checkbox2、checkbox3

    // iterate over checkboxes
    $('#register_students').click(function() { 
        $("div.checkboxes").each(function() {           
            var student = $(this).attr('data');             
            var checkbox1 = ??? 
            var checkbox2 = ???
            var checkbox3 = ???
        });     
        return false;
    });




<td>
<div class='checkboxes' data=8255>
<INPUT type="checkbox"  value="36" class="checkbox1">
<INPUT type="checkbox"  value="14" class="checkbox2">
</div>
</td>

<td>
<div class='checkboxes' data=8244>
<INPUT type="checkbox"  value="36" class="checkbox1">
<INPUT type="checkbox"  value="14" class="checkbox2">
<INPUT type="checkbox"  value="14" class="checkbox3">
</div>
</td>

用这个。

$(this).is(':checked')

返回true或false。喜欢，

$('#register_students').click(function() {
    $("div.checkboxes").each(function(index1) {
        var student = $(this).attr('data');
        cb = [];           
        $('input[type=checkbox]',this).each(function(index2, Element){
           cb[index2] = $(Element).is(':checked');
        });
        // use 'cb' and 'student' as you want. 3 checkbox value are as cb[0], cb[1], cb[2]
    });     
    return false;
});
