Before my development, I've already used native javascript alert for client side validation message. Some people might complaint why I used native javascript alert instead of jQuery dialogbox, it's because of I don't want to include so many script tags and CSS tags for jQuery mobile.

Today, I've got an idea to replace native javascript alert with cfmessagebox. This function will support to display cfmessagebox instead of javascript alert whenever we have put javascript alert in our coding.

I oddly know how to use iframe location in firefox. Honestly, most of our projects are based on Internet Explorer. It's because of ActiveX controls. Why I know how to use iframe location in firefox is because of my junior asked me how to do like that.

I wrote how to download Facebook video Download Facebook video without installing addons in my old post. At that time, Facebook using "embed" tag as displaying their video and it's easy to get original mp4 video from Facebook. Yesterday, one commenter wrote that he cannot download Facebook video regarding the instruction of my previous post. I was confused and cannot understand why he cannot download at all. That's why I've open Facebook video page and reviewed source code of it. Oddly, Facebook don't use "embed" tag as displaying their video anymore and changed their coding for using javascript as displaying. That's why I need to find out how to download original mp4 file of this movie from Facebook again.

It's odd that I've recently known how to do decimal format in javascript. Because, in the new change requests of our projects, I need to do on-the-fly calculation total amount once users change quantity. It seems so simple to use the built-in function of javascript but value parsing via javascript it a bit touch.

Here is the example.

It's the wrong using of fetching decimal value in JS.

Today, I'm very happy that I can change jQueryMobile select Box active style color in iPad safari. Because, current active style ".ui-btn-active" is 100% working for other inputs like text, radio and checkbox but for select box, it doesn't completely work in iPad safari. My boss told me that I need to change all of active input color to "dark blue" instead of default color. That's why I need to change and already played in existing jQueryMobile stylesheet file. But it doesn't work at all. That's why I think I need to hack jQueryMobile existing javascript. After 30 minutes, I found that there are three places I need to change in jQueryMobile existing stylesheet.

The first part is I need to add new class name for active select box in stylesheet.

Today, I need to test some simple javascript coding to detect image manipulation. As we all know, we cannot detect Image width and height with javascript or jQuery before which isn't completely loaded. Now what I want to do is just put loading text and don't show image while it's not completely loaded. It's quite simple and I feel what I want to do might be useful for my future projects. Because I feel displaying image while loading is annoying and shouldn't be good for our clients. That's why I have an idea to do like that.

Today I've found how to save the information of your data when offline (when your internet connection is disconnect). That's same as when Google email work. It's very useful to use because our submitted data is sometimes lost when our connection is disconnect or offline. Using this feature in HTML5 can prevent these bad situation. The important part is we need to check whether our browser can support "localStorage" or not. If not support, cannot develop anymore. If support, let's go.

First of all, we need to create manifest file for "localStorage". It's the main part to let browser know our application will be using "localStorage". So, we need to add all of files name we will be using into this manifest file as follow. Current my simple application, I've used 2 files called index.html and lc.js. So, I need to add as follow

Now I need to let our clients know he/she is now online or office with following javascript.

After that, I need to create index.html file. As HTML5 standard, I need to follow the rule of HTML5.
