ajax使用 ajax+json

首先将ajax写于js方法中,定义事件,让元素触发,触发之后就会有数据产生给服务端

  $.ajax({
               type: "POST",
               url: "test.php",
               data: "name=garfield&age=18",
               success: function(data){
                        $("#myDiv").html('
'+data+'
');
                  }
            });

{
	"msg": "login success",
	"status_code": "200",
	"userlist": [{
		"uname": "zhangsan",
		"age": "12"
	}, {
		"uname": "Lisi",
		"age": "22"
	}]
}

json格式

function loginMethod(){
		var uname=$("#uname").val();
		 $.ajax({
             type: "POST",
             dataType:"json",
             url: "login.do",
             data: {"uname":uname,"oper":"ajaxlogin"},
             success: function(data){
            	 //回调成功函数
            	 var msg=data.msg;
            	 var list=data.userlist;
                 $("#msg_span").html(''+msg+'');
                 var info="";
                 //展示列表信息
                 for(var i=0;i";
                 }
                 $("#user_list").html(info);
              },
              error:function(){
            	  $("#msg_span").html('network connect error');
              }
          });
	}

text文本

$.ajax({
		type : 'POST',
		url : "/plugin/apop/check.do",
		data : {
			"instID" : instID,
			"instCode" : instCode
		},// {instID:LBUI.checkGistJSON.InstID,instCode:LBUI.checkGistJSON.FInstCode},
		async : false,
		dataType : 'text',
		success : function(data) {
			var json = JSON.parse(data.trim());
			var mgs = json.message;
			var success = json.success;
			var JSONdata = json.datas;
			var count=0;
			if (JSONdata.length > 0 && JSONdata != null) {
				for ( var i = 0; i < JSONdata.length; i++) {
					//alert(JSONdata[i].checkDetails);
					count++;
					var html = " 
" +count+"." +JSONdata[i].checkPoint
							+ "
"
							+ JSONdata[i].checkDetails + "
";
					
						$("#firstUL").append(html);
						$('.layui-colla-content p').last().remove();

				}
				if(count>3){
					$("#moreInfo").css("display","block");
				}
			}
		},
		error : function(data) {
			alert(data);
		}
	});
});
