Format JavaScript code

JavaScript code formatting Tool

JS downloaded onlineCodeCode is often compressed (comments, line breaks, indentation, spaces, tabs, and so on are all deleted). If you are studying and studying the code, you will be dizzy. Some editor's "lattice code" function can solve this problem. I searched the internet and found some such tools. Among them, sourceformatx is good and supports many languages, however, fees apply. Unregistered codes larger than 8 K cannot be formatted. The registration fee is 188 yuan, which is too expensive. Although textrush is free of charge, it seems that it has not been released at all; polystyle seems to be good; vs.net plug-in resharper also has this function, such tools seem to have: trita, Eclipse, etc., but finally found the JavaScript code improver, a free tool. He is very simple. Only this function is used to format Js. It can also be used to format and mix HTML code.
Effect:

<Script language = "JavaScript"> var I = 0, S = "", K = 0; function Foo () {for (j = 0; j <10; j ++) {for (I = 0; I <10; I ++) {S = "string1"; k = math. floor (math. random () * 10) ;}for (I = 20; I> 9; I --) {S = "string2"; k = I ;}}</SCRIPT>

In addition, if you want to compress JavaScript code, you can use this: http://www.brainjar.com/js/crunch/demo.html

To use this tool, make sure that each statement is followed by a semicolon (';'Otherwise, an error similar to "Expected ';'" or "missing; before statement" will be reported. For example
X = 3.141592
Y = 2.718281

Will becomeX = 3.141592 y = 2.718281Is an incorrect statement. But there is also a benefit, you can check which places you have missed a semicolon. It is easier to skip the semicolon:P. onreadystatechange = function (){....};AndRssinfos [I] = {ID: idstr, URL: urlstr };These two types.
