ajax asynchronous upload in jquery
本篇文章给大家介绍jquery中的ajax异步上传，在此需要引入ajaxfileupload.js这个js文件。接下来，有需要的朋友一起学习吧
找了好久终于在网上找到了ajax异步上传文件的方法，不过网上大多数是php的 ，我改为struts2写的 大同小异，希望对学习java的人有一定的帮助。我上传的是音乐文件。
ajaxfileupload.js这个js文件是主要文件，一定要导入。
jsp页面 ，其中我还做了p的隐藏*****************************
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+
":"+request.getServerPort()+path+"/";

// alert(ss);
var mp3Name = ss.split(";");
for(var i=0; i<mp3Name.length;i++) {

$('#songName').val(mp3Name[0]);
$('#songsiger').val(mp3Name[1]);

$('#result').html('添加成功');

if (target.style.display=="block"){
target.style.display="none";

</package>
</struts>后来经过调试，发现火狐和ie不兼容 导致无执行争取结果，所以我上传ajaxfileupload.js 我修改了源码
上面是我整理给大家的，希望今后会对大家有帮助。

PHP vs. Ajax: Solutions for creating dynamically loaded content
Jun 06, 2024 pm 01:12 PM
Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.
