JavaScript implements HTML string encoding code

An HTML string is a string with an HTML special symbol such as ' <div id= ' a ' >aklsdjfklsjdfl</div> ', which we usually have to process and then output to prevent the output from being a true HTML element, which is the < into HTML symbol code such as &lt;.

If the string is very long and there are a lot of special symbols in it, how can we simply and efficiently turn them all around? Cycle? Regular expression? Not at all! and look:

The code is as follows	Copy Code
function Bian (a) {return new Option (a). InnerHTML}

That's all! How to use:

The code is as follows	Copy Code
function Bian (a) {return new Option (a). InnerHTML} var a = ' <div id= ' a ' >aklsdjfklsjdfl</div> '; Alert (Bian (a));

By replacing special characters to implement the

1 HTML Encoding:

The code is as follows	Copy Code
function HTMLEnCode (str) { var s = ""; if (Str.length = = 0) return ""; s = str.replace (/&/g, "&gt;"); s = S.replace (/</g, "&lt;"); s = S.replace (/>/g, "&gt;"); s = s.replace (//g, "&nbsp;"); s = s.replace (/'/g, ' ""); s = s.replace (/"/g", "&quot;"); s = S.replace (/n/g, "<br>"); return s; }

2) HTML decoding:

The code is as follows	Copy Code
function HtmlDecode (str) { var s = ""; if (Str.length = = 0) return ""; s = str.replace (/&gt;/g, "&"); s = S.replace (/&lt;/g, "<"); s = S.replace (/&gt;/g, ">"); s = S.replace (/&nbsp;/g, ""); s = s.replace (/'/g, ' ""); s = S.replace (/&quot;/g, "" "); s = S.replace (/<br>/g, "n"); return s; }
