IJsFunction Interface |
A JavaScript function that can be passed between .NET and JavaScript as a method
argument or a return value. The function lifetime is bound to the lifetime of the frame this
function belongs to. When the owner frame is unloaded, all the JavaScript objects are
automatically disposed. An attempt to access a disposed JavaScript object will result
in ObjectDisposedException

SyntaxC#
public interface IJsFunction : IJsObject, IAutoDisposable
The IJsFunction type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | Frame |
Gets the IFrame instance this JavaScript object is bound to.
(Inherited from IJsObject.) |
| IsDisposed |
Indicates if the object is already disposed.
(Inherited from IAutoDisposable.) |
| Properties |
Gets the object properties as a live collection.
Modifying this collection will lead to updating the object properties.
(Inherited from IJsObject.) |
Methods| Name | Description | |
|---|---|---|
 | Invoke(IJsObject, Object) |
Executes the function on the given jsObject with the args.
This method blocks current thread execution until the function finishes
its execution. If the function raises an exception, then JsException with an error
message that describes the reason of the exception will be thrown. Same error message will be
printed in JavaScript Console.
|
| InvokeT(String, Object) |
Executes the function with the given methodName and the args in the
JavaScript object. This method blocks current thread execution until the function finishes
its execution. If the function raises an exception, then a JsException with an error
message that describes the reason of the exception will be thrown. Same error message will be
printed in JavaScript Console.
(Inherited from IJsObject.) |
| InvokeT(IJsObject, Object) |
Executes the function on the given jsObject with the args.
This method blocks current thread execution until the function finishes
its execution. If the function raises an exception, then a JsException with an error
message that describes the reason of the exception will be thrown. Same error message will be
printed in JavaScript Console.
|
| InvokeAsync(String, Object) |
Asynchronously executes the function with the given methodName and the args
in the JavaScript object without blocking the current thread.
(Inherited from IJsObject.) |
| InvokeAsync(IJsObject, Object) |
Asynchronously executes the function on the given jsObject with the args
without blocking the current thread.
|
| InvokeAsyncT(IJsObject, Object) |
Asynchronously executes the function on the given jsObject with the args
without blocking the current thread.

Events| Name | Description | |
|---|---|---|
 | Disposed |
Occurs when the object has been disposed.
(Inherited from IAutoDisposable.) |
Extension Methods| Name | Description | |
