MBS( "WebView.InstallCallback" )
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.
