JavaScript, HTML, CSS
What's behind the scenes?
- In this section, we will learn more about the internals of AppStudio.
- AppStudio is built on top of HTML5, css3 and JavaScript.
- We deliberately left those parts accessible.
- Makes it easy to learn more about HTML5, css3 and JavaScript.
- Advanced users can build almost anything.
Translator
- When an AppStudio program is run, all BASIC code is converted to JavaScript.
- JavaScript is fast!
- JavaScript on a iPhone 5S is almost twice as fast as VB.Net on a desktop!
- Latest iPhones are 100x faster than the original.
- Translation happens only to code modules which have changed.
- You can see your BASIC translated to JavaScript by right clicking in the Code Window.
Controls
- The forms and controls in your project generate css and HTML
- The css defines the controls.
- Controls are identified by their ids.
- The ids are declared in the DOM window object.
- While is why we can do TextBox1.value.
- For each control, a string of HTML is also created.
- These strings are put into an array.
- The array is joined together and put into the form's innerHTML.
- Just like what we were doing the HTMLview!
#Button1 {position:absolute; left:43px; right:auto; top:96px; bottom:auto; height:29px; width:100px}
* Generated JavaScript
Form1.innerHTML=[ "Button",
].join();
Generated Index.html
