jquery ajax后台向前台传list 前台用jquery $.each遍历list

$.ajax({
type: 'post',
url: xxx.action',
dataType: 'text',
success: function(data){
var dataObj=eval("("+data+")");
for(var i=0;i<dataObj.length;i++){
alert(dataObj[i].id+" "+dataObj[i].name);
}

var jsonObj=eval("("+data+")");
$.each(jsonObj, function (i, item) {
alert(item.id + ","  + item.name);
});
},
error: function(text) {}
});

HttpServletResponse res = ServletActionContext.getResponse();
res.reset();
res.setContentType("text/html;charset=utf-8");
PrintWriter pw = res.getWriter();

xxx.setId(1);
xxx.setName("黑色头发");
list.add(xxx);
xxx.setId(2);
xxx.setName("紫色头发");
list.add(xxx);

String json = JSONArray.fromObject(list).toString();

pw.print(json);
pw.flush();
pw.close();
