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
