##### 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" />

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。
