js 根据td节点获取tr节点,及其他td节点的内容,兼容IE、FF、Chrome

html:

<tr class="bg_light" >
       <td style="height:30px" align="center" class="lockX">TTTTTT</td>
       <td align="center" class="lockX">
  TTTTTTTTTTTTTTTTT
       </td>
       <td style="text-align:left" class="lockX">&nbsp;TTTTTTTT&nbsp;</td>
       <td style="text-align:left" class="lockX">&nbsp;TTTTTTTTTT&nbsp;</td>
       <td style="text-align:left" class="unlock">&nbsp;TTTTTTTTTTT&nbsp;</td>
       <td style="text-align:left" class="unlock">&nbsp;TTTTTTTT&nbsp;</td>
       <td align="center" class="unlock">TTTTTTTTT&nbsp;</td>
       <td align="center" class="unlock">TTTTTTT&nbsp;</td>
       <td align="center" class="unlock">TTTTTTTT</td>
       <td align="center" class="unlock"><%=AVO.getRemark()%>&nbsp;</td>
       <td align="center" class="unlock">
  <a onmouseover="javascript:showTargetSys(this)">查看</a>
       </td>
       <td align="center" class="unlock">
  TTT
       </td>
 </tr>

javascript:

function showTargetSys(obj) {
 var trNodes = obj.parentNode.parentNode;
 var tdNodes = trNodes.childNodes;
 var tdNodesArray = new Array();
 for(var i = 0; i < tdNodes.length; i++) {
  var node = "";
  //IE下tagName能识别
  //FF、Chrome下tagName不能识别
  if(document.all) { //IE
   node = tdNodes[i].tagName;
  } else { //非IE
   node = tdNodes[i].nodeName;
  }
  if(node.toUpperCase() == "TD") {
   tdNodesArray.push(tdNodes[i]);
  }
 }
 var serviceMark = "";
 var methodMark = "";
 //IE下innerText能识别
 //FF、Chrome下innerText不能识别
 if(document.all) {
  serviceMark = tdNodesArray[4].innerText;
  methodMark = tdNodesArray[5].innerText;
 } else {
  serviceMark = tdNodesArray[4].textContent;
  methodMark = tdNodesArray[5].innerText;
 }
 
 var random = Math.random();//随机数,只传参,后台不用接收
 var url = "<%=contextPath%>/servlet/AjaxServlet?flag=getTargetSys&serviceid="+serviceId+"&methodid="+methodId+"&random"+random;
 
 $.get(
   url,
   function(response) {
    /*$('#targetSys').html(response);*/
    alert("response: " + response);
   });
 
 
 /*$('#targetSys').css('display', 'block');*/
}
