Form

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:

attributes	The names of HTML attributes which apply to this form, separated by spaces. Design Time.
backgroundColor	Sets the form's background color. Can be a color name, #RRGGBB, rgb(R,G,B), or transparent.
backgroundImage	Sets the form's background pattern or image. Overrides the backgroundColor property. Works best if image is in the project folder. Do not use absolute paths. To stop image from repeating to fill the screen, put background-repeat:no-repeat; into the form's style property. Gradients like linear-gradient(#55aaee,#003366) can be set at design time or runtime. URLs like url(https://www.nsbasic.com/images/eiffel.gif) can be set at runtime only.
centerScreen	If True, the form will be centered on the screen at runtime. Good for different screen sizes. Scrolling must be false. Design Time.
class	The names of CSS classes which apply to this form separated by spaces. Design Time.
designHeight	Used to calculate height if expressed as a percentage. If 0, then same as height in pixels. Design time only.
designWidth	Used to calculate width if expressed as a percentage. If 0, then same as width in pixels. Design time only.
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. Design time only.
height	The height of the form in pixels or a percent of designHeight.
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
modal	If set to true, the form will be displayed centered on top of any other forms. Other forms will be grayed out and cannot be accessed until the form is hidden. Design time only.
language	The programming language used in the code for the form. Can be BASIC or JavaScript. Design time only.
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. Design time only.
parentForm	The name of the parent form. If blank, the main page (NSBPage) is used. Can be used to make a form a child of another control or form.
position	Determines how a form is positioned. Normally set to 'absolute': the form is positioned according to the left and top properties. If set to 'relative', Responsive Design principles apply.
script	Opens the Code Window for the form.
screenMode	How will the form be displayed? Full - Screen using full width and height. Actual - Size of width, height, left and top. Use for Modal forms. Center - in screen, using width and height. Zoom - width and height to screen size and center horizontally. Max of 2. noStyle - no automatic styling, Just use actual class and style properties.
scroll_options	iScroll options. See iScroll docs at https://github.com/cubiq/iscroll.
scrolling	Allow scrolling? Design time only.
setFocusID	The control to get the focus when the form is shown.
style	The CSS style for the form.
width	The width of the form in pixels or percent of designWidtth. Percents can be set at runtime.
reset()	Clear all fields on the form. Runtime only.
Xpert
HTML	HTML to display on the form. This HTML is displayed on the form before any controls are rendered. It can be used instead of the Drag and Drop method of the Design Screen.
script	Opens the Code Window for the form.

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

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)";

// Change the theme of a Form at runtime. Needs to be done each time you show a Form:
$("#NSBPage").page({theme: "a"})   // jQuery Mobile

'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)"

'Change the theme of a Form at runtime. Needs to be done each time you show a Form:
$("#NSBPage").page({theme: "a"})  ' jQuery Mobile
