[]
Gets or sets the full path to the document on the server.
The path starts with the key of a provider which is registered at server for locating specified document.
Gets or sets a value indicating whether the viewer is under full screen mode.
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.
Gets or sets a value indicating the mouse behavior.
The default is SelectTool which means clicking and dragging the mouse will select the text.
Gets the index of the page which is currently displayed in the view panel.
Gets or sets an object containing request headers to be used when sending or requesting data.
The most typical use for this property is in scenarios where authentication is required. For example:
viewer.requestHeaders = { Authorization: 'Bearer ' + appAuthService.getToken(); };
Gets a value indicating whether the control is hosted in an element with right-to-left layout.
Gets or sets the address of C1 Web API service.
For example, http://demos.componentone.com/ASPNET/c1webapi/4.0.20172.105/api/report
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 threshold to switch between mobile and PC template.
Default value is 767px. If width of control is smaller than thresholdWidth, mobile template will be applied. If width of control is equal or greater than thresholdWidth, PC template will be applied. If thresholdWidth is set to 0, then only PC template is applied and if it's set to a large number e.g. 9999, then only mobile template is applied.
Gets or sets a value indicating how to show the document pages.
Gets or sets a value indicating the current zoom factor to show the document pages.
Gets or sets a value indicating the current zoom mode to show the document pages.
Gets or sets the template used to instantiate the viewer 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.
should invalidate the control. Default value for this parameter is true.
Sets the focus to this control.
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.
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.
Determines whether an object exists in another object's prototype chain.
Another object whose prototype chain is to be checked.
Moves to the page at the specified index.
Index (0-base) of the page to move to.
An wijmo.viewer.IPromise object with current page index.
Raises the beforeSendRequest event.
The RequestEventArgs object.
Raises the fullScreenChanged event.
Raises the invalidInput event.
If the event handler cancels the event, the control will keep the invalid input and the focus.
Raises the mouseModeChanged event.
Raises the pageIndexChanged event.
Raises the pageLoaded event.
The PageLoadedEventArgs object.
Raises the queryLoadingData event.
The QueryLoadingDataEventArgs object that contains the loading data.
Raises the refreshing event.
Raises the viewModeChanged event.
Raises the zoomFactorChanged event.
Raises the zoomModeChanged event.
Determines whether a specified property is enumerable.
A property name.
Refreshes the control.
Whether to update the control layout as well as the content.
Reloads the document.
This is useful for force reloading and rerendering the document.
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.
Shows the page setup dialog.
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.
Scales the current page to show the whole page in view panel.
Scales the current page to fit the width of the view panel.
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 before every request sent to the server.
The event allows you to modify request options like URL, headers, data and even the request method, before sending them to the server. The event passes an argument of the RequestEventArgs type, whose properties have the same meaning and structure as the parameters of the wijmo.httpRequest method, and can be modified to update the request attributes.
For example, you can put an authentication token to the 'Authorization' header:
viewer.beforeSendRequest.addHandler((s, e) => { e.settings.requestHeaders.Authorization = 'Bearer ' + appAuthService.getToken(); });
If the URL is used to induce an HTTP request that is executed by the browser automatically (for example, if the URL is used as a parameter to the window.open() function, or as a HTML link), then the e.settings argument will be null.
Occurs after the full screen mode is changed.
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 control loses the focus.
Occurs after the mouse mode is changed.
Occurs after the page index is changed.
Occurs when the next page has been loaded from the server, and its SVG has been rendered.
Occurs when querying the request data sent to the service before loading the document.
Occurs after the control has refreshed its contents.
Occurs when the control is about to refresh its contents.
Occurs after the view mode is changed.
Occurs after the zoom factor is changed.
Occurs after the zoom mode is changed.
Defines the PDFViewer control for displaying the PDF document.
The serviceUrl property indicates the url of C1 Web API which provides PDF services. The PDF services use C1PdfDocumentSource to process PDF document.
Here is the sample to show a PDF document:
import { PdfViewer } from '@mescius/wijmo.viewer'; var pdfViewer = new PdfViewer('#pdfViewer'); pdfViewer.serviceUrl= 'http://demos.componentone.com/ASPNET/c1webapi/4.0.20172.105/api/report'; pdfViewer.filePath= 'PdfRoot/DefaultDocument.pdf';
