javascript; JS版HtmlEncode方法，結果與C#中HttpUtility.HtmlEncode方法一樣。

<script type="text/javascript"> 
function HTMLEncode(html) 
{ 
var temp = document.createElement ("div"); 
(temp.textContent != null) ? (temp.textContent = html) : (temp.innerText = html); 
var output = temp.innerHTML; 
temp = null; 
return output; 
} 

function HTMLDecode(text) 
{ 
var temp = document.createElement("div"); 
temp.innerHTML = text; 
var output = temp.innerText || temp.textContent; 
temp = null; 
return output; 
} 

var html = "<br>dffdfqqqqq"; 
var encodeHTML = HTMLEncode(html); 
alert("方法一：" +encodeHTML); 
var decodeHTML = HTMLDecode(encodeHTML); 
alert("方法一：" +decodeHTML); 
</script>
