Copy code The code is as follows: - From : http://www.iecn.net/bbs/view/105499.html - IECN.NET 2006-09-22 -->

type="text/javascript"&gt ; //Remove all comments String.prototype.DeleteComment = function () { var str = this.replace(/(['"])(. ?)([' "])/g,function(s,s1,s2,s3){return s1 s2.replace(/[/*]/g,"\$&") s3}); str = str.replace( ///[^r] |/*[sS] ?*//g,""); str = str.replace(/(['"])(. ?)(['"])/ g,function(s,s1,s2,s3){return s1 s2.replace(/\([^\])/g,"$1") s3}); return str; } //Format Code String.prototype.FormatCode = function () { return this.replace(/\$/mg,"").replace(/[^s>;]$/ mg,"$&;"); } //Delete extra spaces before and after the string String.prototype.Trim = function (m) { return this.replace( m ? /^s*|s*$/mg : /^s*|s*$/g, ""); } //Run code function RunCode(obj) { window.open('','_blank').document.write(obj.value); }

Test code: &lt ;br/> /* Test Code */ var x=5; document.write("x = // " x); document.write("bh/* " x); document. write("x =jjhj */hhhhhh " x); document.write("x = // " x);

alert(22)

var a="/fwe/////wefawef"; alert(/^/*[^/]*$/.test(a)); //Comment

Step 1: Delete comment

Step 2: Format code

Step 3: Remove spaces on both sides

Step 4: Run code
