未檢查

<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_chk0.gif" title=""> 
</td> 

經過

<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=""> 
</td> 

按鈕（批次標記）

<input type="submit" onclick="DoRowBatch()" style="width:150px; background-color:darkslateblue;" class="formsubfree" value="Tag Selected Applications" id="ANSWER.TTQ.MENSYS.5." name="ANSWER.TTQ.MENSYS.5."> 

點擊他們可以去到下一個步驟（批量標籤）電子複選框，如果他們不那麼警報需要彈出說「至少選擇一個複選框」

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"); 
    } 
}
