底层步骤
实例对象
创建HTTP请求
发送请求
设置回调函数
- 使用jQuery
$.ajax({
"url":"/AjaxDemoServlet",
"type":"POST",
"data":"name="+name+"&pwd="+pwd,
"dataType":"JSON",
"success":callBack,
"error":function () {
alert("验证时出现错误！");
}
});
function callBack(data) {
...
}
$.post({url,data,callBack,dataType};
function callBack(data) {
...
}
$(selector).load(url[,data][,complete]);//加载HTML内容
- JSON
var person={"name":"Mary","age":25,"spouse":null};
var nation=["中国","美国","俄罗斯"];
var p=[{"name":"Mary","age":25},{"name":"Bob","age":27}];
//将普通对象转换为JSON对象
先导入jar包
String newsJSON=JSON.toJSONString();
