经过

<td valign="middle" align="center" style="vertical-align: middle;" class="" title=""> 
    <img onclick="new eXcell_ch(this.parentNode).changeState(true); (arguments[0]||event).cancelBubble=true; " src="/dhtmlxGrid/codebase/imgs/item_chk1.gif" title="">

点击他们可以去到下一个步骤（批量标签）电子复选框，如果他们不那么警报需要弹出说“至少选择一个复选框”

function DoRowBatch() { 
    var Checkedlist = mygrid.getCheckedRows(15); 
    if (CheckedList.checked){ 
     document.getElementById('ANSWER.TTQ.MENSYS.4.').value = Checkedlist; 
     document.getElementById('ANSWER.TTQ.MENSYS.5.').click(); 
    } 
    else 
    { 
    alert ("You must first select applications, using the checkboxes, before bulk tagging them"); 
    } 
}
