ChangeTarget (Function)

In french: ChangeDestination

Changes the target of a button action.

By default, the target is defined in the "General" tab of the button run or current page

Caution: ChangeTarget can be directly used in the browser process corresponding to the server action of control:

browser click code for a button, a link or an image.
"Whenever modified" code for the radio buttons, check boxes, list boxes or combo boxes.

ChangeTarget has no effect in the other browser processes or in a local browser procedure even if this procedure is called by one of the above-mentioned processes.

Example

// -- Browser click code of the button
// The target of the button defined in the description window (current frame)
ChangeTarget(CurrentBrowser)

// -- Server click code of the button
IF CheckUserName(EDT_UserName) = False THEN
// Refreshes the PAGE_Identification page
PageRefresh(PAGE_Identification)
ELSE
// Displays the home page
PageDisplay(PAGE_Welcome)
END

Tip: optimize the size of your HTML files

For PageDisplay, SemiDynamicPageDisplay, DynamicSiteDisplay and FileDisplay, we recommend that you change the target in these functions directly. Indeed, the corresponding JavaScript code included in the HTML files is smaller.
