ajax即“Asynchronous Javascript And XML”（异步JavaScript和XML），是指一种创建交互式网页应用的网页开发技术。

ajax = 异步 JavaScript和XML（标准通用标记语言的子集）。

ajax 是一种用于创建快速动态网页的技术。

通过在后台与服务器进行少量数据交换，ajax 可以使网页实现异步更新。这意味着可以在不重新加载整个网页的情况下，对网页的某部分进行更新。

传统的网页（不使用 ajax）如果需要更新内容，必须重载整个网页页面。异步请求（XMLHttpRequest对象），局部刷新（本质是js dom）

ajax的用途还有填写表单时候自动判断用户名是否重复，比如你写博客写到一半突然电脑重启了，可以恢复你写了一半的内容。

get用于获取数据，有字数限制，请求提包括在url中，post无限制，用于修改服务器的内容。

get是安全的请求，需要保证不修改信息。

1、ajax一般用于当前页面，不实现页面跳转 

2、ajax端：怎样异步得监听服务器端的状态呢？通过onreadystatechange监听readystate属性

request.onreadystatechange = function() {

<span>if (request.readyState===4) {</span>

  • 0：请求未初始化（还没有调用 open()）。
  • 1：请求已经建立，但是还没有发送（还没有调用 send()）。
  • 2：请求已发送，正在处理中（通常现在可以从响应中获取内容头）。
  • 3：请求在处理中；通常响应中已有部分数据可用了，但是服务器还没有完成响应的生成。
  • 4：响应已完成；您可以获取并使用服务器的响应了。

所以一般都是判断等于4之后进行相应的操作。

但注意这个和request的status是不一样的

比如readystate=4但是status=404表示响应完成但是响应的内容是没有找到文件

所以一般做法是==200的时候返回内容，其他就显示发声错误即可。

注意在post请求中要设置url 成encode，及url解码，否则不能正确给出结果

request.setRequestHeader("Content-type","application/x-www-form-urlencoded");

但是url解码会有一个问题，由于进行urlencoded的时候加号会自动解码成空格，&会被解码成变量连接符，所以如果出现这些字符必须要进行转码

（在做canvas上传图片的url的时候遇到了这个问题）

Pic = Pic.replace(/\+/g, "%2B");
Pic = Pic.replace(/\&/g, "%26");

3、服务器通过echo来返回给传递ajax的界面。

（提示：zendstudio内置的浏览器对于ajax的页面总是会显示上一次的页面，所以改成在外置浏览器里运行

　　preference-general-web browser里面设置。）

如果只返回一行简单的，可以不用jason，jason可以更方便返回不同键值的数据。
