Bug 179979 – WebDriver: handle user prompts shown while executing scripts

• Component: WebDriver
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

15.2 Executing Script

The rules to execute a function body are as follows. The algorithm will return success with the JSON representation of the function’s return value, or an error if the evaluation of the function results in a JavaScript exception being thrown or at any point during its execution an unhandled user prompt appears.

If at any point during the algorithm a user prompt appears, the user prompt handler must be invoked. If its return value is an error, it must immediately return with that error and abort all subsequent substeps of this algorithm.
