constructor(element: any, options?): MultiAutoComplete
Initializes a new instance of the MultiAutoComplete class.
The DOM element that hosts the control, or a selector for the host element (e.g. '#theCtrl').
The JavaScript object containing initialization data for the control.
Gets or sets a value that indicates whether the control should automatically expand the selection to whole words/numbers when the control is clicked.
Gets the ICollectionView object used as the item source.
Gets or sets the template used to instantiate DropDown controls.
Gets or sets the name of the CSS class used to highlight any parts of the content that match the search terms.
Gets or sets the delay, in milliseconds, between when a keystroke occurs and when the search is performed.
Gets or sets the name of the property to use as the visual representation of the items.
Gets the drop down element shown when the isDroppedDown property is set to true.
Gets or sets a CSS class name to add to the control's drop-down element.
This property is useful when styling the drop-down element, because it is shown as a child of the document body rather than as a child of the control itself, which prevents using CSS selectors based on the parent control.
Event that fires when items in the drop-down list are created.
You can use this event to modify the HTML in the list items. For details, see the formatItem event.
Gets or sets the name of a property to use for getting the value displayed in the control's input element.
The default value for this property is null, which causes the control to display the same content in the input element as in the selected item of the drop-down list.
Use this property if you want to de-couple the value shown in the input element from the values shown in the drop-down list. For example, the input element could show an item's name and the drop-down list could show additional detail.
Gets the DOM element that is hosting the control.
Gets the HTML input element hosted by the control.
Use this property in situations where you want to customize the attributes of the input element.
Gets or sets a value that indicates whether the control should use a fade-in animation when displaying the drop-down.
Gets or sets a value indicating whether the drop-down list displays items as plain text or as HTML.
Gets or sets a value that determines whether the control is disabled.
Disabled controls cannot get mouse or keyboard events.
Gets or sets a value that indicates whether the drop down is currently visible.
Gets or sets a value that enables or disables editing of the text in the input element of the ComboBox (defaults to false).
Gets or sets a value that indicates whether the user can modify the control value using the mouse and keyboard.
Gets or sets a value that determines whether the control value must be set to a non-null value or whether it can be set to null (by deleting the content of the control).
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.
Gets or sets a function used to customize the values shown in the drop-down list. The function takes two arguments, the item index and the default text or html, and returns the new text or html to display.
If the formatting function needs a scope (i.e. a meaningful 'this' value), then remember to set the filter using the 'bind' function to specify the 'this' object. For example:
comboBox.itemFormatter = customItemFormatter.bind(this);
function customItemFormatter(index, content) {
if (this.makeItemBold(index)) {
content = '<b>' + content + '</b>';
}
return content;
}
Gets or sets the array or ICollectionView object that contains the items to select from.
Gets or sets a function that provides list items dynamically as the user types.
The function takes three parameters:
For example:
autoComplete.itemsSourceFunction = function (query, max, callback) {
// get results from the server
var params = { query: query, max: max };
$.getJSON('companycatalog.ashx', params, function (response) {
// return results to the control
callback(response);
});
};
Gets or sets the maximum height of the drop-down list.
Gets or sets the maximum width of the drop-down list.
The width of the drop-down list is also limited by the width of the control itself (that value represents the drop-down's minimum width).
Gets or sets the maximum number of items to display in the drop-down list.
Gets or sets the maximum number of items that can be selected.
Setting this property to null (the default value) allows users to pick any number of items.
Gets or sets the minimum input length to trigger auto-complete suggestions.
Gets or sets the string shown as a hint when the control is empty.
Gets a value indicating whether the control is hosted in an element with right-to-left layout.
Gets or sets a string containing a comma-separated list of properties to use when searching for items.
By default, the AutoComplete control searches for matches against the property specified by the displayMemberPath property. The searchMemberPath property allows you to search using additional properties.
For example, the code below would cause the control to display the company name and search by company name, symbol, and country:
var ac = new wijmo.input.AutoComplete('#autoComplete', {
itemsSource: companies,
displayMemberPath: 'name',
searchMemberPath: 'symbol,country'
});
Gets or sets the index of the currently selected item in the drop-down list.
Gets or sets the item that is currently selected in the drop-down list.
Gets or sets an array containing the items that are currently selected.
Gets or sets the name of the property used to control which item will be selected.
Gets or sets the value of the selectedItem, obtained using the selectedValuePath.
Gets or sets the name of the property used to get the selectedValue from the selectedItem.
Override the value for indicating control should not display a drop-down button.
addEventListener(target: EventTarget, type: string, fn: any, capture?: boolean): void
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 method).
Failing to remove event listeners may cause memory leaks.
Target element for the event.
String that specifies the event.
Function to execute when the event occurs.
Whether the listener is capturing.
applyTemplate(classNames: string, template: string, parts: Object, namePart?: string): HTMLElement
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. 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', template, {
_tbx: 'input',
_btnUp: 'btn-inc',
_btnDn: 'btn-dec'
}, 'input');
Names of classes to add to the control's host element.
An HTML string that defines the control template.
A dictionary of part variables and their names.
Name of the part to be named after the host element. This determines how the control submits data when used in forms.
beginUpdate(): void
Suspends notifications until the next call to endUpdate.
deferUpdate(fn: Function): void
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.
dispose(): void
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.
disposeAll(e?: HTMLElement): void
Disposes of all Wijmo controls contained in an HTML element.
Container element.
endUpdate(): void
Resumes notifications suspended by calls to beginUpdate.
getControl(element: any): Control
Gets the control that is hosted in a given DOM element.
The DOM element that is hosting the control, or a selector for the host element (e.g. '#theCtrl').
getDisplayText(index?: number): string
Gets the string displayed in the input element for the item at a given index (always plain text).
The index of the item to retrieve the text for.
getTemplate(): string
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, it will override the template defined by the DropDown base class.
indexOf(text: string, fullMatch: boolean): number
Gets the index of the first item that matches a given string.
initialize(options: any): void
Initializes the control by copying the properties from a given object.
This method allows you to initialize controls using plain data objects instead of setting the value of each property in code.
For example:
grid.initialize({
itemsSource: myList,
autoGenerateColumns: false,
columns: [
{ binding: 'id', header: 'Code', width: 130 },
{ binding: 'name', header: 'Name', width: 60 }
]
});
// is equivalent to
grid.itemsSource = myList;
grid.autoGenerateColumns = false;
// etc.
The initialization data is type-checked as it is applied. If the initialization object contains unknown property names or invalid data types, this method will throw.
Object that contains the initialization data.
invalidate(fullUpdate?: boolean): void
Invalidates the control causing an asynchronous refresh.
Whether to update the control layout as well as the content.
invalidateAll(e?: HTMLElement): void
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 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.
onGotFocus(e?: EventArgs): void
Raises the gotFocus event.
onIsDroppedDownChanged(e?: EventArgs): void
Raises the isDroppedDownChanged event.
onIsDroppedDownChanging(e: CancelEventArgs): boolean
Raises the isDroppedDownChanging event.
onLostFocus(e?: EventArgs): void
Raises the lostFocus event.
onSelectedIndexChanged(e?: EventArgs): void
Raises the selectedIndexChanged event.
onSelectedItemsChanged(e?: EventArgs): void
Raises the selectedItemsChanged event.
onTextChanged(e?: EventArgs): void
Raises the textChanged event.
refresh(fullUpdate?: boolean): void
Refreshes the control.
Whether to update the control layout as well as the content.
refreshAll(e?: HTMLElement): void
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.
removeEventListener(target?: EventTarget, type?: string, fn?: any, capture?: boolean): number
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.
selectAll(): void
Sets the focus to the control and selects all its content.
Occurs after the drop down is shown or hidden.
Occurs before the drop down is shown or hidden.
Occurs when the value of the selectedIndex property changes.
Occurs when the value of the selectedItems property changes.
The MultiAutoComplete control allows users to pick items from lists that contain custom objects or simple strings.
