在js中怎么获得动态增加的表格中某列的数据

Question

在js中怎么获得动态增加的表格中某列的数据

Answer 1

什么教动态增加的某列值？
这个动态添加不也是你自己做的吗？自己做的弄一个有规律的id.再用老方法xxxx.getElementById("xxxx").VALUE去拿值不行么

Answer 2

我代码是这样的了，是在dwr中生存的动态表单function getSupplyList(Read){
    var contractId=document.all._10011T_CONTRACT_ID99.value;
    if(Read=='Read'){
    commonBean.getSupplyListByContractId(contractId,function(data){
    DWRUtil.removeAllRows("SUPPLY");
    DWRUtil.addRows("SUPPLY",data,SUPPLYcellRead)
    })
    }else{
    commonBean.getSupplyListByContractId(contractId,function(data){
    DWRUtil.removeAllRows("SUPPLY");
    DWRUtil.addRows("SUPPLY",data,SUPPLYcell)
    })
    }
   
   
}
var SUPPLYcell=[
function(value){return value.SUPPLIER_ID;},
function(value){return value.SUPPLIER_NAME;},
function(value){return value.SUPPLIER_TYPE;},
function(value){return value.SUPPLIER_LINKMAN;},
function(value){return value.SUPPLIER_CONTACT;},
function(value){
return "<a href='javascript:void(0)' onclick='viewSupply("+value.SUPPLIER_ID+")'>查看</a> "+
"<a href='javascript:void(0)' onclick='delSupply(" + value.SUPPLIER_ID + ")'>删除</a> "; 
}
];我要获得第三列的数据，怎么获得
