Answer 1

executeScript()

executeScript() executes a JavaScript in the context of the currently selected frame or window. The script fragment provided will be executed as the body of an anonymous function.

If the script has a return value (ie if the script contains a return statement), then the following type of objects are returned:

• For an HTML element, this method returns a WebElement
• For a decimal, a Double is returned
• For a non-decimal number, a Long is returned
• For a boolean, a Boolean is returned
• For all other cases, a String is returned.
• For an array, a List is returned with each object following the rules above. Nested lists are also supported.
• For a map, a Map is returned with values following the rules above.
• If the value is null or there is no return value, null is returned
