abort-current-inline-script
This snippet aborts the execution of an inline script when a property is either read or written.
Name | Description | Mandatory |
---|---|---|
api | The API function or property name to anchor on. It can also be the path to that property. If the property is a direct child of window , this parameter will be the property name. If you want to access a sub property, though, this parameter becomes a chain of properties separated by dots. | Yes |
search | If specified, only scripts containing the given string are prevented from executing. If the string begins and ends with a slash ( / ), the text in between is treated as a regular expression. | No |
The following table lists examples that use the
abort-current-inline-script
filter:Filter | Result |
---|---|
abort-current-inline-script setDefaultTheme
| The code that calls/writes the setDefaultTheme global function throws an exception. |
abort-current-inline-script document.head.appendChild | The code that calls/writes the appendChild function throws an exception.
This function is a property of head , which is a property of the document global object.
Be cautious when using this approach; it blocks any code that appends an element to head . |
abort-current-inline-script Object.prototype.networkListener | The code that reads/writes the networkListener property throws an exception. This example shows that you can attach the filter to prototype properties. |
abort-current-inline-script btoa BOOTLOADER_LOADED | The code that calls/writes the btoa global function throws an exception.
This filter would only work inside inline scripts whose text content contains the BOOTLOADER_LOADED string. |
abort-current-inline-script document.createElement /ru-n4p|ua-n4p|загрузка.../ | The code that calls/writes the createElement function of document throws an exception.
This filter would only work inside inline scripts whose text content matches the /ru-n4p|ua-n4p|загрузка.../{regex} . |
Keep the following tradeoffs in mind when you use the
abort-current-inline-script
filter:- The snippet is executed after all of a page's inline scripts. As a result, you should only attach properties read inside of a callback, which can be executed after the script.
- You can only attach this snippet to global properties, or properties of the
window
object.
