Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IJavaScriptExecutor. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).RemarksThe ExecuteScript(String, Object)method executes JavaScript in the context of the currently selected frame or window. This means that "document" will refer to the current document. If the script has a return value, then the following steps will be taken:
- For an HTML element, this method returns a IWebElement
- For a number, a Int64 is returned
- For a boolean, a Boolean is returned
- For all other cases a String is returned.
- For an array,we check the first element, and attempt to return a ListT of that type, following the rules above. Nested lists are not supported.
- If the value is null or there is no return value, is returned.
Arguments must be a number (which will be converted to a Int64), a Boolean, a String or a IWebElement. An exception will be thrown if the arguments do not meet these criteria. The arguments will be made available to the JavaScript via the "arguments" magic variable, as if the function were called via "Function.apply"
