JS获取循环表格中input的值

[my0563]

请问我该如何获取到鼠标点击的tr行input的值呢？
现在获取到的是始终是第一条记录。。。。。。。

function popUserDetail(x){
	var popUp = document.getElementById("popUserDetail");
  var h = (x.rowIndex)*20;
	    popUp.style.top= 25 + h + "px";
	    popUp.style.left="142px";
	    popUp.style.width="200px";
	    popUp.style.height="100px";
	    popUp.style.visibility="visible";	  
	  var customerId = document.getElementsByTagName("input")[0].value;
    alert (customerId);
	}

    	   while ($records = mysql_fetch_array($rows)) 
 	         { 
 	         	$arr = ct($records['uniqueid']);
 	         	$fileLastUploadTime  = $arr[1];
 	        
       print       '
                    <tr id="rIndex" onclick="popUserDetail(this)" onmousemove="hidePopUserDetail()">
                    <input type="hidden" name="customerId" value="'.$records["uniqueid"].'"> 
                    <input type="hidden" name="firstLogin" value="'.$records["firstLogin"].'"> 
                    <input type="hidden" name="address" value="'.$records["address"].'">                                    
  	         	      <td width="40px">'.st($records['lastT'],$fileLastUploadTime).'</td>
 	         	        <td width="100px">'.$records['barName'].'</td>
 	         	        <td width="160px">'.$records['lastLogin'].'</td>
 	         	        <td width="160px">'.date("Y-m-d H:i:s",$arr[1]).'</td>
 	         	        <td width="150px">'.$records['endTM'].'</td>
 	         	        <td width="40px">'.$arr[0].'</td>
 	         	        <td width="40px" style="border-right:0;">'.$records['version'].'</td>
 	         	        </tr>';
 	         	} 
 print	         	 '</table>
                    <div class="popUserDetail" id="popUserDetail">
                          <table>
                          <tr><td id="">客户编号:</td><td id="cId"></td></tr>                                          
                          <tr><td>客户地址:</td><td></td></tr>
                          <tr><td>初次登陆:</td><td>备份周期:</td></td></tr>
                          <tr><td>联系QQ:</td><td>联系电话:</td></td></tr>
                          </table>
                    </div>

看看你这句是什么？

var customerId = document.getElementsByTagName("input")[0].value;

索引是0当然永远是第一个。

改为：
var customerId = document.getElementsByTagName("input")[x.rowIndex].value;

Try It Again!

[码无边]

var customerId = document.getElementsByTagName("input")[0].value;写错了

[Quote=引用楼主 的回复:]
<input type="hidden" name="customerId" value="'.$records["uniqueid"].'">
<input type="hidden" name="firstLogin" value="'.$records["firstLogin"].'">
<input type="hidden" name="address" value="'.$records["address"].'">

jQuery不好用吗？
获取上面三行的对象：
$("input[type='hidden']");

非要用js的话：
针对楼主当前代码，input对象依次为0,1,2

var btns = document.getElementsByTagName("input");
	for(var i=0; i < btns.length; i++){
		if(btns[i].value == ""){
			alert(btns[i].value);
		}
	}
