JavaScript url 编码转换

在Web应用中经常会发现碰到被编码的字符串，看起来很费劲，这里提供一个简单的编解码程序，可以方便地查看原码或转码：

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
<title>unescape,decodeURI</title>
</head>

<body>
<textarea id="textarea1" rows="4" cols="79"></textarea>
<br>
<input type="button" value="convert" οnclick="convert()">
<input type="button" value="unescape" οnclick="un_escape()">
<input type="button" value="unconvert" οnclick="unconvert()">
<input type="button" value="escape" οnclick="escape_()">
<br>
<textarea id="textarea2" rows="5" cols="79"></textarea>
<script lang="javascript" rows="4" cols="80" name="S1">

    function convert(){
        document.getElementById('textarea2').value = unescape(decodeURI(document.getElementById('textarea1').value));
    }
    
    function unconvert(){
        document.getElementById('textarea1').value = escape(encodeURI(document.getElementById('textarea1').value));
    }
    
    function un_escape(){
        document.getElementById('textarea2').value = unescape(document.getElementById('textarea1').value);
    }
    
    function escape_(){
        document.getElementById('textarea1').value = escape(document.getElementById('textarea2').value);
    }
</script>
</body>

</html>
