- Note: Internet browsers allow only one action on the page per treatment.
- Choosing a type of button
Choose the action of the button in a page
When defining the action of a button in a page, a button can perform different operations depending on the type of the action selected. The different available choices The operation performed during the action is chosen in the button description window ("General" tab).
The possible operations during the action are: - Send values to the server (submit):
The button validates all the controls in the current page and returns the value of the controls to the server. Then, the server performs the specified action. - Don't send anything to the server:
The button performs the requested action but it does not return the content of the controls found in the current page to the server. - Delete content of the controls in the browser (reset) - for compatibility:
The button clears all page controls (except for the control initialized programmatically).
Note: Internet browsers allow only one action on the page per treatment. Some types of buttons automatically trigger an action on the page ("Send the value of controls to the server (submit)"). If the PageSubmit or EmailOpenMail functions are used in the browser "Click" event of these buttons (or in a procedure called by this event), this function will be ignored: only the button action will be performed. Consequences: Functions PageSubmit or EmailOpenMail cannot be used in a code that (automatically or not) causes an action.. These functions are ignored: - in the click code of a button that performs the action "Send values to the server (submit)".
- in the click code of a button that performs an action different from "Do not send anything to the server".
- if PageSubmit is followed by EmailOpenMail (in the current event, in a procedure called by the current event or in another process called by Execute).
- if EmailOpenMail is followed by PageSubmit (in the current event, in a procedure called by the current event or in another process called by Execute).
To use PageSubmit or EmailOpenMail from a button ("Click" browser event of the button), this button must have the following characteristics ("General" tab in the description window): - Operation on fields: "Execute browser click code only"..
- Action: "Send nothing to the server".
Choosing a type of button Let's see some "standard" examples for using buttons in a page: | | | | Action to perform | Example | Operation available with the action |
|---|
| Send data of the current page to the server to be processed | Registration form
The button checks whether the entered information is correct and displays a confirmation page. | Send value of controls to server (submit) | | Perform a process on the server, without retrieving the data of the current page | Menu page with buttons.
Each button is used to display a page of the site | None | | Perform a process in browser code | Perform a simple calculation, an input check, ... | None | | Display a static page of the site | Display the home page of the site | None | | Display a page external to the site | Start a search engine | None | | Reset the page controls | Clear the controls of the current page | Reset page controls |
