AJAX提交的一个例子
前端
$(document).ready( function() { $.ajax( { async:false, type : 'GET', data:{}, contentType : 'application/json;charset=UTF-8', url : 'testAjax', dataType : 'json', success : function(data) { if (true) { alert(data); var String_option=""; $('#info').html("共" + data[0].id + "条数据。<br/>"); $.each(data, function(i, item) { String_option=String_option+"<option value="+item.a+">"+item.b+"</option>"; $('#info').append( "A属性:" + item.a + ",B属性:" + item.b+"<br/>"); }); //alert(String_option); $("#selectId").html(String_option); } }, error : function() { alert("error") } }); });
后台
@RequestMapping(value = "testAjax",method = RequestMethod.GET) @ResponseBody public String testAjax(){ List<Test> list=testService.getAllTest(); /* Map<String, Object> modelMap = new HashMap<String, Object>(3); modelMap.put("total", "1"); modelMap.put("data", list); modelMap.put("success", true); */ return JSONUtil.toJSONString(list); }
