The example in this article describes how JavaScript uses encodeURI() and decodeURI() to obtain string values. Share it with everyone for your reference. The details are as follows:

JavaScript uses encodeURI() and decodeURI() to obtain the string value. It cannot be the string displayed in the address bar. I often saw people asking this question online before. I accidentally found it online. I wonder if it is what you want. Let’s see the effect first.

Let’s take a look at the running effect first:

The specific code is as follows: 

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>使用系统函数</title>
<script language="JavaScript">
<!--
 function showMsg()
 {
  var strURL= url.value;
  var encodeStr = encodeURI(strURL);
  var temp = encodeStr+"\n";
  temp += decodeURI(encodeStr);
  alert(temp);
 }
-->
</script> 
</head>
<body>
<div>
  请输入一个URL：<input name="url" type="text" id="url" value="/search.php&#63;keyword=搜索关键字" size="60" />
  <input type="submit" name="button" id="button" value="我要提交" onclick="showMsg();" /></div>
 <dIV class="vc" style="margin: 20px auto" >
<h2>使用encodeURI()和decodeURI()函数：</h2>
</dIV>
</body>
</html>

I hope this article will be helpful to everyone’s JavaScript programming design.
