Handling Web Forms in Your JADE Code

If your JADE application is HTML-enabled and it is invoked as a Web application, the display of your Web page is determined by the methods of the Form class listed in the following table.

Method	Action
show	Executes the load method, generates the HTML, and returns the HTML to the Web server.
showModal	Not supported, and generates an error at run time or actions the show method. (For details, see "Enabling Your JADE Application for HTML Thin Client Access", later in this chapter.)
unloadForm	Removes the form from the Web session list of open forms.

In addition, you can use the Form class:

webBrowserAutoRefreshInterval property, to specify the number of seconds after which the Web page is automatically refreshed and when that property is set to a non-zero value.

The default value of zero (0) for the automatic refresh interval indicates that the Web page does not refresh automatically. If you specify an automatic refresh interval and you do not specify the URL to invoke when the number of seconds is reached, control is returned to the JADE application.
webBrowserAutoRefreshURL property, to specify the URL to invoke when the automatic refresh interval is reached.
webBrowserDisableBackButton property, to specify whether the currently displayed Web page refreshed instead of displaying the previous page when the user clicks the Web browser Back button. As it is not possible to disable the Back button or the menu item from scripting, set this property to true if you want to prevent the user from going to a previous Web page.
