My excuse

Because I have the experience in JavaScript not so much, so some of JavaScript example in this blog might be the same you have seen (or might look like you have ever written them). Please let me know if you are not pleasant to publish in my blog and I will delete them immediately as I can. Frankly speaking some example I publish came from the books and some have been searched from the internet which I understand they are free for anyone to use them. I just collect them to my blog for whoever would like to use them for their work or any purpose.
