That question is generic.

I can't understand because when i include a bit of javacript code, only for testing something in magento, the following error returns:

Uncaught TypeError: Cannot read property

Anyone could give me an exemple of how a testing code should be?

This is the code I tested:


Magento use prototype.js framework. So if you want to use jQuery to read an element.

Use jQuery instead of $

Your issue is probably because $ is calling prototype and you are trying to access a property of a jQuery object. You should use a jQuery.noConflict() to prevent this kind of issues in the future. There are several guides to achieve this with different approaches, use the one you are more comfortable with.

  • Thanks a lot I'll find out more about what you said Jul 8 '15 at 19:17
