Description

Forms act as containers for controls. To go to a new form, use the ChangeForm() function.

To add a Form to your app, choose Add Form from the Project menu at the top of the screen. Forms can be deleted in the Project Explorer.

Scrolling forms are allowed, with a couple of notes. Footerbars won't work (since the bottom needs to scroll up), nor will scrolling controls (which confuse the scroller).

The information on a form can be submitted to a URL by using the Ajax function.

Properties

Standard properties are supported, plus:

backgroundColor backgroundColor. Can be name or RGB value.
backgroundImage Will override the background with a pattern or an image.
linear-gradient(#55aaee, #003366);

If you are using jQuery Mobile, the best way to control the background color is to use themes. It will work better on PhoneGap Build.

fullscreen True/False. If True, the form will automatically fill the entire device screen. The IDE will still use height and width at design time.
height The height of the form in pixels. Default is 460.
left The left position of the form. Use this for forms that are not full screen.
locked If set to true, the controls on the Design Screen cannot be moved
language The programming language used in the code for the form. Can be BASIC or JavaScript.
openMode Should the form be open at startup? Use this for forms which are to remain open. There is no need to set this for the first form of the project: that is set in Project Properties.
script Opens the Code Window for the form.
scroll_options iScroll options. See iScroll docs at http://iscrolljs.com.
scrolling Allow scrolling?
script Opens the Code Window for the form.
style The CSS style for the form.
setFocusID The control to get the focus when the form is shown.
width The width of the form in pixels. Default is 320. Percents can be set at runtime.
reset() Clear all fields on the form. Runtime only.

Events

Standard events are supported, plus:

onhide() Called when form hidden as a result of ChangeForm()
onkeypress(event) Called when a key is tapped on a form.
onshow() Called by firstform and when form is shown as a result of ChangeForm()
onsubmit() Called when a form is submitted.

Example (Basic)

Change color at runtime

  Form1.style.backgroundColor="red"
  Form1.style.width="100%"  

To prevent the image from repeating to fill the full window:

  NSBPage.style.backgroundRepeat = "no-repeat"

Set gradient background at runtime:

Form1.style.backgroundImage="linear-gradient(#55aaee, #003366)"

Example (JavaScript)

  Form1.style.backgroundColor="red";
  Form1.style.width="100%";

To prevent the image from repeating to fill the full window:

  NSBPage.style.backgroundRepeat = "no-repeat";
Form1.style.backgroundImage="linear-gradient(#55aaee, #003366)";
