How to run all of the JavaScript library in TextPad 6

Question

Sorry if this is a simple or silly question but i have been trying to find the answer for a long time and i have had no luck in my search.

I am using TextPad 6 to learn JavaScript code(requested by tutor) but i have noticed a lot of the functions/methods etc i use are coming up with an error;

"Microsoft JScript runtime error: Object doesn't support this property or method"

Does anyone know how i can get TextPad to recognize any JavaScript code so i am not limited to the code i can use.

An example of the code it does not like is;

 if(selectedIndex.indexOf(index)>-1)

Thank you

I don't know exactly what your JS runtime is (sounds like it's equivalent to IE <= 8)* or how it's configured in TextPad, but I suggest that you'd be better off just running your code in a modern browser, like Chrome. That would also allow you to interactively debug it.

• Array.prototype.indexOf() wasn't supported by IE until version 9.
