Gets or sets the background color to render the control.
The default value for this property is rgb(255,255,255).
Indicates whether to enable bearer bar (thick black border) around the symbol.
The default value for this property is false.
Gets or sets the forecolor to render the control.
The default value for this property is rgb(0,0,0).
Gets or sets font info for the label text of the control.
Indicates whether to show the check digit in the label text of the control.
The default value for this property is false.
Gets the DOM element that is hosting the control.
Gets or sets a value that determines whether the control is disabled.
Disabled controls cannot get mouse or keyboard events.
Gets a value that indicates whether the control is currently handling a touch event.
Gets a value that indicates whether the control is currently being updated.
Indicates whether the current value property value is valid.
When this property changes its value, the isValidChanged event gets triggered.
Gets or sets where to render the value of the control.
The default value for this property is LabelPosition.Bottom.
Gets or sets the narrow and wide bar ratio of the control.
The possible property values are 1:2 or 1:3. The default value for this property is {@link NarrowWideRatio.OneToThree}.
Gets or sets the size of quiet zone (the blank margin) around the barcode symbol.
Gets or sets the rendering type of the control.
The default value for this property is RenderType.Canvas.
Gets a value indicating whether the control is hosted in an element with right-to-left layout.
Indicates whether the value is rendered under the symbol.
The default value for this property is true.
Gets or sets a value of the tabindex attribute associated with the control.
tabindex attribute value can be defined statically for a Wijmo control by specifying it on the control's host HTML element. But this value can't be changed later during application lifecycle, because Wijmo controls have complex structure, and the control may need to propagate this attribute value to its internal element to work properly.
Because of this, to read or change control's tabindex dynamically, you should do it using this property.
Gets or sets the current code value rendered by the control.
Gets or sets the template used to instantiate Barcode controls.
Adds an event listener to an element owned by this Control.
The control keeps a list of attached listeners and their handlers, making it easier to remove them when the control is disposed (see the dispose and removeEventListener methods).
Failing to remove event listeners may cause memory leaks.
The passive parameter is set to false by default, which means the event handler may call event.preventDefault(). If you are adding passive handlers to touch or wheel events, setting this parameter to true will improve application performance.
For details on passive event listeners, please see Improving scrolling performance with passive listeners.
Target element for the event.
String that specifies the event.
Function to execute when the event occurs.
Whether the listener should be handled by the control before it is handled by the target element.
Indicates that the handler will never call preventDefault().
Applies the template to a new instance of a control, and returns the root element.
This method should be called by constructors of templated controls. Therefore, this method is not available. It is responsible for binding the template parts to the corresponding control members.
For example, the code below applies a template to an instance of an InputNumber control. The template must contain elements with the 'wj-part' attribute set to 'input', 'btn-inc', and 'btn-dec'. The control members '_tbx', '_btnUp', and '_btnDn' will be assigned references to these elements.
this.applyTemplate('wj-control wj-inputnumber', templateString, {
_tbx: 'input',
_btnUp: 'btn-inc',
_btnDn: 'btn-dec'
}, 'input');
@param classNames Names of classes to add to the control's host element. @param template An HTML string that defines the control template. @param parts A dictionary of part variables and their names. @param namePart Name of the part to be named after the host element. This determines how the control submits data when used in forms.
Suspends notifications until the next call to endUpdate.
Checks whether this control contains the focused element.
Executes a function within a beginUpdate/endUpdate block.
The control will not be updated until the function has been executed. This method ensures endUpdate is called even if the function throws an exception.
Function to be executed.
Disposes of the control by removing its association with the host element.
The dispose method automatically removes any event listeners added with the addEventListener method.
Calling the dispose method is important in applications that create and remove controls dynamically. Failing to dispose of the controls may cause memory leaks.
Resumes notifications suspended by calls to beginUpdate.
Sets the focus to this control.
Gets base64 string of the barcode.
Gets the barcode image data info; only supported for canvas rendering.
Gets the size of barcode symbol.
Gets the HTML template used to create instances of the control.
This method traverses up the class hierarchy to find the nearest ancestor that specifies a control template. For example, if you specify a prototype for the ComboBox control, which does not specify a template, it will override the template defined by the DropDown base class (the nearest ancestor that does specify a template).
Determines whether an object has a property with the specified name.
A property name.
Invalidates the control causing an asynchronous refresh.
Whether to update the control layout as well as the content.
Determines whether an object exists in another object's prototype chain.
Another object whose prototype chain is to be checked.
Raises the invalidInput event.
If the event handler cancels the event, the control will keep the invalid input and the focus.
Raises the isValidChanged event.
Raises the refreshing event.
Determines whether a specified property is enumerable.
A property name.
Refreshes the barcode image.
Specifies whether to recalculate the barcode size.
Removes one or more event listeners attached to elements owned by this Control.
Target element for the event. If null, removes listeners attached to all targets.
String that specifies the event. If null, removes listeners attached to all events.
Handler to remove. If null, removes all handlers.
Whether the listener is capturing. If null, removes capturing and non-capturing listeners.
The number of listeners removed.
Returns a date converted to a string using the current locale.
Returns a string representation of an object.
Returns the primitive value of the specified object.
Disposes of all Wijmo controls contained in an HTML element.
Container element.
Gets the control that is hosted in a given DOM element.
The DOM element that hosts the control, or a CSS selector for the host element (e.g. '#theCtrl').
Invalidates all Wijmo controls contained in an HTML element.
Use this method when your application has dynamic panels that change the control's visibility or dimensions. For example, splitters, accordions, and tab controls usually change the visibility of its content elements. In this case, failing to notify the controls contained in the element may cause them to stop working properly.
If this happens, you must handle the appropriate event in the dynamic container and call the Control.invalidateAll method so the contained Wijmo controls will update their layout information properly.
Container element. If set to null, all Wijmo controls on the page will be invalidated.
Refreshes all Wijmo controls contained in an HTML element.
This method is similar to invalidateAll, except the controls are updated immediately rather than after an interval.
Container element. If set to null, all Wijmo controls on the page will be invalidated.
Occurs when the control gets the focus.
Occurs when invalid input is detected.
Invalid input may occur when the user types or pastes a value that cannot be converted to the proper type, or a value that is outside the valid range.
If the event handler cancels the event, the control will retain the invalid content and the focus, so users can correct the error.
If the event is not canceled, the control will ignore the invalid input and will retain the original content.
Occurs when the isValid property value changes.
Occurs when the control loses the focus.
Occurs after the control has refreshed its contents.
Occurs when the control is about to refresh its contents.
Represents a control for drawing ITF-14 barcode type.
