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;
}
