I'm new to magento and I'm creating an eshop now. I want to add some jquery code to prepopulate some fields I want. For example I want when adding a new Product Category to auto choose "isAnchor" = true and active = true. Also I want when adding a new product to auto choose a certain tax selection and prepopulate some other fields with some values I want as default.
Can some one suggest on where should I put my code in each case to achieve my goal?
Thanks in advance.
