Sys.Services.AuthenticationService.logout(redirectUrl, logoutCompletedCallback, failedCallback, userContext);
Parameters
Parameter |
Description |
|---|---|
redirectUrl |
The URL to redirect the browser to on successful logout. The default is null. |
logoutCompletedCallback |
The function that is called when the logout has finished. The default is null. |
failedCallback |
The function that is called if the logout has failed. The default is null. |
userContext |
User context information that you are passing to the callback functions. |
Remarks
If redirectUrl is null or is an empty string, the page is redirected to itself after the call to the authentication Web service finishes and the completed callback function is called. This makes sure that any user-related data is cleared from the page.
If redirectUrl is not null or is a non-empty string, the page is redirected to the specified URL after a successful call to the Web service. This URL can be an absolute virtual path, a relative virtual path, or a fully qualified domain name and a path.
If the call to the Web service fails, the page is not redirected or refreshed. Instead, the failed callback function is called.
Example
