How to programatically get the content from a JavaScript editor [message #160080]

Hi,

I want to get the content of a JavaScript editor (including dirty part).

Below code works well for ".java" and ".jsp" editor, but doesn't work for
".js" editor:

-------------------------------------------
IEditorPart part =
workbench.getActiveWorkbenchWindow().getActivePage().getActi veEditor();
ITextEditor texteditor = (ITextEditor)part;
IDocument doc =
texteditor.getDocumentProvider().getDocument(workbench.getAc tiveWorkbenchWindow().getActivePage().getActiveEditor().getE ditorInput());

System.out.println("Content in editor: " + doc.get());
-----------------------------------------------

The problem is "part" can not be casted to "ITextEditor", it's an instance
of "JSMultiPageEditorPart" class. Any ideas?

Thanks

Hi, try this:

IEditorPart activeWin= this.window.getActivePage().getActiveEditor();
IDocument doc = ((ITextEditor)
activeWin).getDocumentProvider().getDocument(activeWin.getEd itorInput());
String text = doc.get();

Most of the WTP editors respond to a request for an adapter for
ITextEditor.class--except for the JavaScript editor. Next week's
1.5M5 build will have the fix.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=127340

This should work, then:

IEditorPart part =
workbench.getActiveWorkbenchWindow().getActivePage().getActi veEditor();
ITextEditor texteditor = null;
if(part instanceof ITextEditor) {
texteditor = (ITextEditor) part;
}
else {
texteditor = (ITextEditor) part.getAdapter(ITextEditor.class);
}
// hopefully you'd have a null check here
IDocument doc =
texteditor.getDocumentProvider().getDocument(workbench.getAc tiveWorkbenchWindow().getActivePage().getActiveEditor().getE ditorInput());
System.out.println("Content in editor: " + doc.get());
