经典JS的HTML转义与反转义字符

//HTML转义
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; 
} 

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