Hi everyone, I’m a programming student and I need help with an exercise, can someone help me? I have to create a form with a budget, (already created, I leave the code below), which depending on what I put later has to increase or decrease the price, the problem comes in the javascript part, which I am not capable of, and it was If someone can help me to generate it, I would be very grateful. It must have the following characteristics.

  • In the product field: it is a select with four options: select category / web page design / app development / seo/sem positioning each product will have a different price

  • In the term field: it is a numerical field, depending on the number of months in which you wish to receive the product, a discount will be applied to the final budget.

  • Extras: I put three checks: online store / graphic design / social networks. that each option selected will increase the budget.

  • in the budget field: in this field it must be updated with any change made in the product choices, months and extras, without using buttons or refreshing the page.

I am missing the js code that I am not able to do it, can someone help me please? Thank you very much in advance, I leave you the html code of the entire form:

Not to be rude, but you are asking us to do your homework for you.

We can help to explain some concepts for you, or if you provide the scripting code that you have done up to this time, we can give some pointers from there.

But if we do the programming for you, it is then us that are passing the test, not you.
We will not support sabotaging your education by doing the work that you need to do yourself.

The bullet points look like the assignment is copy & pasted as the question …

If you can’t do “the javascript part”, and the assignment includes javascript, either:

  1. You haven’t paid attention to your lessons. Go back and review your instruction in the class.
  2. Your instructor has failed to give you the knowledge necessary to complete the assignment. Contact the instructor and ask if they meant to put it into the assignment. (It’s not common, but sometimes an instructor might make this mistake!)
