Number
Number widget is an editor widget that accepts numeric input.
You can:
- Can be used in conjunction with the selected app Locale to display the number in the appropriate format.
- Limit the input by applying maximum character length.
- Apply regular expressions to validate client side number.
note
Number widget applies the number formatting as per the Locale automatically. In case you do not wish to change the app behavior as per the Locale, use the Text widget with Number Type. For more information, see Text Widget with Number Type.
Properties
| Property | Description |
|---|---|
| Name | The name is a unique identifier for Number widget. |
| Placeholder | A placeholder is a text to show in the editor when there is no value. A common use of this is a search box that says in faint gray italicized text "Search..." which disappears as soon as the user starts to edit the text box. This is a useful alternative to a caption if you are constrained in space and asking for something simple of the user. |
| Accessibility | |
| Hint | Any text or an HTML you enter for this property will be shown as a tooltip if the mouse hovers over this widget for 1.5 seconds. |
| Tab index | The tab index attribute specifies the tab order of an element. You can use this property to change the default tabbing order for widget access using the tab key. The value can range from 0 to 32767. The default is 0 and -1 makes the element non-focusable. NOTE: In Safari browsers, by default, Tab highlights only text fields. To enable Tab functionality, in Safari Browser from Preferences -> Advanced -> Accessibility set the option "Press Tab to highlight each item on a webpage". |
| Shortcut key | The shortcut key property specifies a shortcut key to activate/focus an element. (*See below for details) |
| Layout | |
| Width | The width of your widget can be specified in px or % (i.e 50px, 75%). |
| Height | The height of your widget can be specified in px or % (i.e 50px, 75%). |
| Default Value | |
| Value | This is the default value to display value for an editor widget. Note that the display value is just what the user sees initially, and is not always the dataValue returned by the widget. |
| Validation | |
| Required | A required editor in wm.LiveForm may refuse to save without a required field. |
| Regular Expression | Enter any regular expression to be used to validate user input for client-side input validation. |
| Minimum value | Enter minimum value user is allowed to enter. |
| Maximum value | Enter maximum value user is allowed to enter. |
| Step | Use the stepper to increment/decrement the input value by the specified step interval. Example: if step='3', legal numbers could be -3, 0, 3, 6, etc. |
| Behavior | |
| Auto Focus | This property makes the element get focused automatically when the page loads. |
| Read Only | Selecting this checkbox property prevents the user from changing the data value of a widget. |
| Show | Showing determines whether or not a component is visible. It is a bindable property. |
| Load on Demand (visible only when show property is bound to a variable) | When this property is set and show property is bound, the initialization of the widget will be deferred till the widget becomes visible. This behavior improves the load time. Use this feature with caution, as it has a downside (as we will not be able to interact with the widget through script until the widget is initialized). When show property is not bound the widget will be initialized immediately. |
| Disabled | If the disabled property is true (checked) the value of the editor cannot change. The widget becomes display-only. |
| Allow Trailing Zeros | This property specifies whether to keep trailing zeros after decimal point or not. |
| Update value on | If the selected value is blur: data value will be updated on blur event, default: data value will be updated on key up. |
