WebView.InstallCallback

Installs JavaScript callback into web viewer.

Component Version macOS Windows Linux Server FileMaker iOS SDK
WebView 1.3 Yes Yes No No No

Parameters

none

Description

Installs JavaScript callback into web viewer.
This function needs to be called one time to enable JavaScript to reach out from the web viewer to run a FileMaker Script.
One strategy is to call this function on start-up before any WebViewers have been displayed.

To call back from Javascript to FileMaker, you assign a string to the window.status property:

window.status="Filename:Scriptname"
or
window.status="Filename:Scriptname:Parameter"

The Parameter part can contain ":". Filename must include file extensions so FileMaker finds the database file.

You can also call it within a link with "javascript:window.status='Filename:Scriptname:Parameter'". Like this: href="javascript:window.status='callbacks.fp7:Another Script:Hello World'".
Does not work currently with Internet Explorer 10 on Windows.

Not supported for WebKit 2.x (FileMaker 16 Mac), but works in FileMaker 16, when using a Web Viewer created using WebView.Create.

For FileMaker 16, please check WebView.AddScriptMessageHandler function as a replacement.
