JavaScript escape() 函数定义和用法
escape() 函数可对字符串进行编码，这样就可以在所有的计算机上读取该字符串。
语法：
escape(string)
例子：
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="stylesheet" href="https://cdn.bootcss.com/twitter-bootstrap/4.3.1/css/bootstrap.min.css">
<script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script>
<script src="https://cdn.bootcss.com/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script>
<style>
</style>
</head>
<body>
</body>
<script>
document.write(escape("wang xiaoting!") + "<br />")
document.write(escape("?!=()#%&"))
</script>
</html>
JavaScript unescape() 函数定义和用法
unescape() 函数可对通过 escape() 编码的字符串进行解码。
语法：
unescape(string)
在本例中，我们将使用 escape() 来编码字符串，然后使用 unescape() 对其解码：
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="stylesheet" href="https://cdn.bootcss.com/twitter-bootstrap/4.3.1/css/bootstrap.min.css">
<script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script>
<script src="https://cdn.bootcss.com/twitter-bootstrap/4.3.1/js/bootstrap.min.js"></script>
<style>
</style>
</head>
<body>
</body>
<script type="text/javascript">
var test1="wang xiao ting !"
test1=escape(test1)
document.write (test1 + "<br />")
test1=unescape(test1)
document.write(test1 + "<br />")
</script>
</html>
举个栗子：
实际应用在项目里面
html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Dashboard | Nadhif - Responsive Admin Template</title>

首先使用escape对字符串进行编码，然后使用unescape() 函数对编码的字符串进行解码。
