JS实现HTML标签转义及反转义解析

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