flask中使用ajax 处理前端请求,每隔一段时间请求不通的接口,结果展示同一页面

 需求:

flask中使用ajax 处理前端请求,每隔一段时间请求不通的接口,结果展示同一页面

用到 setTimeout方法,setTimeout(function(){},1000);setTimeout 中的 function 为第二次请求 就可以了

效果如图:请求了二个接口,间隔5秒,展示在同一页面 

 

html:test.html

<html>
<head></head>
<body>

<div class="header">
<h4>标题XXX</h4>
</div>
<div class="body">
<form class="form" method="post">
<br class="form-a"/>
<div class="form-b">
<label for="aaa">&nbsp;&nbsp;&nbsp;&nbsp;XXX:&nbsp;&nbsp; <input class="form-control1" type="a" id="a"
name="a" maxlength="11"
placeholder="请输入XXX"/> </label>
</div>
<div class="box">
<label>&nbsp;XXXX:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</label>
<label class="radio"> <input type="radio" id="b" name="b" value="0" checked=""/><span>b1</span> </label>
<label class="radio"> <input type="radio" id="b" name="b" value="1"/><span>b2</span> </label>
