=======================================================================================
function getDutyCode(select){
var name=select.name;
var re=/lialityNAME/i;
var id;
id=name.replace(re,'lialityID');
alert("责任险代码输入栏name:"+id);
var s=document.getElementsByName(id);
alert("责任险代码输入栏name:"+s.name);
}
在这个函数中我拼装出责任险代码输入栏的name,但是再由该名字却取不到责任险代码输入栏的属性,请指点下
[解决办法]
var s=document.getElementsByName(id);
此时你的s是一个数组,你可以这样
alert("责任险代码输入栏name:"+s[0].name);
