之前写过一个原始的、无封装的页面，没有引入任何外部js，直接实例化Ajax的XmlRequest对象去异步调用接口，参见Ajax异步调用http接口后刷新页面，可对比一下。

现在我们用jquery包装异步调用:

1、在html中导入jquery脚本

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" type="text/css" href="./css/jquery.json-viewer.css">
<link rel="stylesheet" type="text/css" href="./css/wave.css">
<link rel="stylesheet" type="text/css" href="./css/memcacheview.css">
</head>
<body>
<div class="container skin-1">
<div class="main-container">
<div class="main transitions-3">
<div class="json-checker-box no-json">
<div class="json-checker">
<div class="cache-key-box">
<input type="" name="cache_key" id="cache_key" class="cache-key">
<div class="history-box"></div>
</div>
<div class="operation-box">
<button class="check-btn waves-effect ">查询</button>
<button class="update-btn waves-effect ">刷新</button>
<button class="delete-btn waves-effect ">删除</button>
</div> </div>
<div class="category-choosed choosed-hide">缓存块：<span></span></div>
<div class="loading loading-hide"></div>
</div>
<div class="json-renderer-box">
<div class="fullscreen-btn" title="全屏"></div>
<div class="upfold-btn" title="隐藏搜索栏"></div>
<input type="checkbox" name="collapsed" class="checkbox-btn" id="collapsed_btn" title="数据是否折叠">
<input type="checkbox" name="withQuotes" class="checkbox-btn" id="withQuotes_btn" title="键值是否加引号">
<div class="nojson-btn" title="全屏搜索"></div>
<div class="json-renderer-container">
<pre class="json-renderer" id="json_renderer"></pre>
</div>
</div>
<div class="info-notify"></div>
</div>
</div>
<div class="slidebar transitions-3">

<div class="menu"> <div class="fold-btn"><div class="fold-icon"></div></div>
<span class="menu-title">缓存</span>
<input type="radio" name="skin" value="skin-2" class="skin-radio">
<input type="radio" name="skin" value="skin-1" class="skin-radio" checked="checked">
</div> <ul class="category">

</ul>
<div class="water"></div>
</div>
<div class="cache-name-notify"></div> </div> <script src="./js/jquery-3.2.1.min.js"></script>
<script src="./js/jquery.json-viewer.js"></script>
<script src="./js/wave.js"></script>
<script src="./js/memcacheview.js"></script>
</body>
</html>

2、在js脚本中祭出ajax利器，memcacheview.js文件：

$(document).ready(function() {
window.dataCtrl = {
init: function() {
var _this = this;
this.portNum = "9092";

}
this.isSlidebarHide = false;
this.isUpFold = false;
this.isFullSearch = true;
this.operationType = 1;
this.cacheHistory = localStorage.getItem("cacheHistory")?localStorage.getItem("cacheHistory").split(","):[];
this.changeSkin();
this.initHistory();
Array.prototype.removeByValue = function(val) {
for(var i=0; i<this.length; i++) {
if(this[i] == val) {
this.splice(i, 1);
break;
}
}
}; },
addListener: function() {
var _this = this;
$(".category").on("click", ".category-item", function(e) {
