load
<a href="" onclick="load()">使用JQuery执行load方法</a>
//有两次刷新, 先走 onClick的方法,取到数据回来之后,赋值显示。 接着 走 href=""的路径,但是这个属性没有给值,所以会把当前的页面重新再刷新一次。所以导致看不见值。
//找到这个元素, 去执行加载的动作, 加载/day16/DemoServlet02 , 得到的数据,赋值显示
$("#aaa").load("/day16/DemoServlet02" , function(responseText , statusTXT , xhr) {
//找到id为text01的元素, 设置它的value属性值为 responseText 对应的值
$("#aaa").val(responseText);
});
Get
$.get("/day16/DemoServlet02" , function(data ,status) {
$("#div01").text(data);
});
Assignment display
- val ( "aa");

$ ( "# Element id") load (url address).;
