Building a form with JSON and Ajax

in Using jQuery • 5 years ago

Hi,

Looking at this example, I managed to create a drop-down menu which gets its content from a JSON file:

Building a from using JSON

However, I'm sure there is a better way to achieve this.

Could you please show me how would you solve this?

Thank you

How is that a form?

Why do you bother with <select>s? it would be more natural as <a>s. And less clicking.

You are right. It's not a form. I meant building a drop-down menu.

But this is not important. Important is the way I wrote the JavaScript.

I want to know what would be the better code for achieving the same result.

A <select> should use a change event. But your select has nothing to change to. Which is why I suggest you don't use a <select>.

But I'm trying to learn how to create dynamically a drop-down by using JSON data.

I don't want to use anything but a select. :-) Even if it doesn't make sense.

Use more than one option, and use the change event. A FAQ is not a good use of a <select>.

OK, now I'm using <a>.

Thanks for that.

But what about the JavaScript code?

Maybe you are using <a>s in your head. But the plunker is not.

Hahahah....

I just changed <a> to div, as I don't see any difference.

You would have to make more changes than just that.

Without an updated plunk, I can't guess what you have done.

I suggest that you design without using AJAX. When you have something pretty that works, you can create the element dynamically with your JSON data.

Now I'm trying the same thing with another JSON file, but it doesn't work.

What is wrong with my code?
