单击下拉列表时，我需要填充一个表格。 哪个选项表现更好？

Question

I can either:

-Get the information using AJAX, creating a request every time I click on the dropdown.

-Populate the form passing the information to div like this:

@foreach($items as $item)
<div id="name_{{$item->id}}" value="{{$item->name}}"></div>
<div id="date_{{$item->id}}" value="{{$item->date}}"></div>
...
@endforeach

And then setting the value of the form with javascript, making a single request that extracts all the information and passing it to the site.

I have already done both, but I would like to know which one would be the most performant.

Answer 1

The answer is both, but depends on the case.

For instance if you use the ajax method and the dropdown box is never pressed is better than the passing the values.

If the dropdown box is hit once or more than once, the second method will be better. But you will have also a downside: you'll not get the newest version of the dropdown box information from where ever you get it.
