根据值选中或取消选中具有相同类名的所有复选框

Question

我在多个div中有以下复选框.

<div class="div1">
    <input type="checkbox" class="chkbox" value="101"> This is 101
    <input type="checkbox" class="chkbox" value="102"> This is 102
    <input type="checkbox" class="chkbox" value="103"> This is 103
</div>
<div class="div2">
    <input type="checkbox" class="chkbox" value="110"> This is 110
    <input type="checkbox" class="chkbox" value="102"> This is 102
    <input type="checkbox" class="chkbox" value="101"> This is 101
</div>

如上所示,一些复选框在多个div上具有相同的值(例如,101).现在,每当选中复选框时,我都需要检查具有相同值的其他复选框.同样,取消选中.

$(".chkbox").change(function() {
    // If checked
    if (this.checked)
           // find other checkboxes with same value and check them
    else
           // find other checkboxes with same value and uncheck them
}

你可以这样做:

$(".chkbox").change(function() {
    var val = $(this).val();
  if( $(this).is(":checked") ) {

    $(":checkbox[value='"+val+"']").attr("checked", true);
  }
    else {
        $(":checkbox[value='"+val+"']").attr("checked", false);
    }
});
