Description

Shows the DebugBar for the web viewer on Windows.
With DebugBar you can inspect HTML elements, see scripts and modify elements on the fly.
There is a JavaScript console to quickly edit something if needed.

Please download and install DebugBar extension for Internet Explorer:
https://www.debugbar.com

You may need to buy a license for it to use all features.

Known issues:
  • The toolbar has a gear button, where you can pick locations. Choosing a location there may crash FileMaker.
  • If FileMaker runs on a screen with >100% scaling, the picker may not work correctly unless you pass 1 for Flags parameter, but then icons may be smaller.
  • HTTPs tab shows no data.
  • You may need to click reload in the DebugBar (orange arrow in toolbar) when switching to another page.
  • Running JavaScript works, but doesn't show errors or results.
  • The inspect element in context menu command does not work.

For FileMaker 19.4 or newer in MBS Plugin 11.5 or newer, this will redirect to WebView.ShowDevTools function and show developer tools.

Examples

Show DebugBar:

# Show Debugbar in file WebViewer DebugBar

# Show debug bar if available
Set Variable [ $r ; Value: MBS("WebVIew.ShowDebugBar"; "web") ]
If [ MBS("IsError") ]
    Show Custom Dialog [ "Failed to show debug bar" ; $r ]
End If
