jquery ajax后台向前台传list 前台用jquery $.each遍历list
下边是两种前台接收并遍历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) {}
});

下边是后台接收并遍历list

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();
