js实现的unicode和中文的相互转化
代码示例如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title> Unicode to Chinese </title>
<meta name="Generator" content="EditPlus">
<meta name="Author" content="">
<meta name="Keywords" content="">
<meta name="Description" content="">
<script language="javascript">
function unicode2chinese() {
var obj= document.getElementById("content");
var strContent = obj.value;
//alert(strContent);
if (strContent==null||strContent.length==0) {
alert("please input unicode value");
return;
}
var strTest=unescape(strContent.replace(/\\u/g,'%u'));
//alert(strTest);
//document.writeln(strTest);
obj.value=strTest;
}
function chinese2unicode() {
var objInChinese = document.getElementById("contentInChinese");
var strContent = objInChinese.value;
//alert(strContent);
if (strContent==null||strContent.length==0) {
alert("please input chinese value");
return;
}
var strTest=strContent.replace(/[^\u0000-\u00FF]/g,function($0){return escape($0).replace(/(%u)(\w{4})/gi,"&#x$2;")});
strTest=strTest.replace(/;/g,'');
strTest=strTest.replace(/&#x/g,'\\u');
//alert(strTest);
//document.writeln(strTest);
objInChinese.value=strTest;
}
</script>
</head>
<body>
<textarea name="content" id="content" rows="5" cols="100"></textarea>
<input type="button" name="btTransform" value="Unicode2Chinese" onclick="unicode2chinese();"/>
<p>
<textarea name="contentInChinese" id="contentInChinese" rows="5" cols="100"></textarea>
<input type="button" name="btTransformToUnicode" value="Chinese2Unicode" onclick="chinese2unicode();"/>
