HTML encoding and decoding

 var htmlutil = {
/*1. Implements HTML transcoding */
 Htmlencode:function (HTML) {
//1 with a browser internal translator. First, dynamically create a container label element, such as D        IV 
 var temp = document.createelement ("div"); 
 2. Then set the string to be converted to this element of innertext (ie support) or textcontent (Firefox, Google support) 
 (temp.textcontent! = undefined)? (temp.textcontent = html): (Temp.innertext = html);        
//3. Finally returns the InnerHTML of this element, which is a string that has been converted by HTML encoding 
 var output = temp.innerhtml; 
 temp = null; 
 return output;         
}, 
/*2. Implement HTML decoding with the browser internal translator */
 Htmldecode:function (text) {
//1. First, dynamically create a container tag element, such as Div 
 var temp = document.createelement ("div");        
//2. Then set the string to be converted to this element's InnerHTML (ie, Firefox, Google support) 
 temp.innerhtml = text; 
 3. Finally return this element of the innertext (ie support) or textcontent (Firefox, Google support), that is, the HTML decoded string. 
 var output = Temp.innertext | | temp.textcontent; 
 temp = null; 
 return output; 
} 
}; 

Summary: encoded by innerHTML Way, by innertext | | Textcontent mode decoding
