I have errors in my JS part.

Question

I have errors in my JS part, can someone check my code and tell me what changes must I do ? My project : https://code.sololearn.com/W01KYK017LSt/?ref=app

Answer 1

your problem is: the function change_quantity is inside the function change_product, so you can't call it just by its name

I would suggest you to rewrite your javascript, and make every function separate, it's not a good idea to put functions inside other functions, however if you do the you need to use the word 'new' and every function and/or variable needs to be initialized with 'this'
for example:

this.var = 5;

this.funcName = function (){}

hope this helps

Answer 6

Press a buy button, an overlay will appear, and select a quantity different from 1, an error will appear, and I don't know how to correct it.

Answer 7

At the end I want to display the final price the user has to pay ( product's price * quantity ) but there is an error line 32 in JS, and I would like to correct this error before finishing the rest.
