Implement this interface to handle javascript exceptions globally.
For an example of how to implement handler see cefpython.CreateBrowser(). For a list of all handler interfaces see API > Client handlers. Table of contents:
| Parameter | Type |
|---|---|
| browser | Browser |
| frame | Frame |
| Return | void |
Called shortly after (process message delay) the V8 context for a frame has been created.
If the page does not contain <script> tags then this method won't get called.
| Parameter | Type |
|---|---|
| browser | Browser |
| frame | Frame |
| Return | void |
Called shortly after (process message delay) the V8 context for a frame was released.
Due to multi-process architecture in CEF 3, this function won't get called for the main frame in main browser. To send a message from the renderer process a parent browser is used. If this is the main frame then this would mean that the browser is being destroyed, thus we can't send a process message using this browser. There is no guarantee that this will get called for frames in the main browser, if the browser is destroyed shortly after the frames were released.
