String | UTF-8 |
原始碼:
<table border="1" cellpadding="5" rules="all"> <tr><td>String</td><td>UTF-8</td></tr> <tr><td><input id="str2utf8InputBoxy" size="30" value="123abcABC許功蓋" /></td><td><input id="str2utf8OutputBoxy" size="30" value="" /></td></tr> <tr><td><button id="str2utf8ConvertBoxy">String to UTF-8</button></td><td><button id="utf8ToStrConvertBoxy">UTF-8 to String</button></td></tr> </table> <script type="text/javascript"> function $(id) {return document.getElementById(id.substr(1));} var str2utf8 = function(word) { var output = ""; for(key in word) { var dec = word[key].charCodeAt(0); if((dec>47 && dec<58) || (dec>64 && dec<91) || (dec>96 && dec<123)) { output += '%' + dec.toString(16); } else { output += encodeURIComponent(word[key]); } } return output; }; $('#str2utf8InputBoxy').onclick = function() { $('#str2utf8InputBoxy').select(); }; $('#str2utf8OutputBoxy').onclick = function() { $('#str2utf8OutputBoxy').select(); }; $("#str2utf8ConvertBoxy").onclick = function() { $("#str2utf8OutputBoxy").value = str2utf8($("#str2utf8InputBoxy").value); }; $("#utf8ToStrConvertBoxy").onclick = function() { $("#str2utf8InputBoxy").value = decodeURIComponent($("#str2utf8OutputBoxy").value); }; </script>
後記:
此程式乃用來補足encodeURIComponent語法未包含數字與英文的UTF-8轉換問題。
