JavaScript中如何将一个字符串，转换成一个对象类型？？

Question

var resText = xmlHttp.responseText;//能得到一个字符串:
alert(eval(resText.name));

Answer 1

上面错了。
alert(eval(resText).name);

Answer 2

<script>
var a='"address":"","email":"[email protected]","name":"test5","id":"6"';
var Aarray=a.split(",");
var result=new Array();
for(var i=0;i<Aarray.length;i++)
{
temp=Aarray[i].split(":");
eval("result['"+temp[0].replace(/\"/g,'')+"']='"+temp[1].replace(/\"/g,'')+"'");
}
alert(result["name"])
</script>

resText = '{"address":"","email":"[email protected]","name":"test5","id":"6"}';
res_array = resText.split(',');
for(i=0;i<res_array.length;i++){
  if(res_array[i].indexOf('name') != -1){
   res = res_array[i];
   alert(res.substring(res.indexOf(':')+2,res.length-1));
  }
}
