jquery – 在表行中启用“禁用控件”

我想在选中相应的chkView时启用该行的编辑和删除复选框,如果未选中则禁用它们.首先,这段代码根本没有触发.我哪里错了.

HTML

<table id="table_forms">
    <tr>
        <td><input type="checkBox" class="chkView"/>View</td>
        <td><input type="checkBox" class="chkEdit" disabled/>Edit</td>
        <td><input type="checkBox" class="chkdelete" disabled/>delete</td>
    </tr>
   <tr>
        <td><input type="checkBox" class="chkView"/>View</td>
        <td><input type="checkBox" class="chkEdit" disabled/>Edit</td>
        <td><input type="checkBox" class="chkdelete" disabled/>delete</td>
    </tr>
</table>

JS：

$(document).on('change','.chkView',function(){
var row = $(this).closest('tr');
    if($(this).prop("checked",truE))
    {
        $(row).find('.chkEdit').prop("disabled",falsE);
        $(row).find('.chkdelete').prop("disabled",falsE);
    }
    else
        {
        $(row).find('.chkEdit').prop("disabled",truE);
        $(row).find('.chkdelete').prop("disabled",truE);
    }

});

$(document).on('change',function(){
var row = $(this).closest('tr');
    if($(this).is(':checked'))
    {           
      $(row).find('.chkEdit,.chkdelete').prop("disabled",falsE);    
    }
    else
    {
      $(row).find('.chkEdit,truE);     
    }
});
