How to put a value in a hidden input when clicking on an element on the page?

Question

AJAX

Now I'll try to explain it more clearly)) For example, there is a tag <p>, when you click on it, you need to put it in the <input>values ​​valye="" tag id <p>. Please tell me how to do this, I'm just starting to learn ajax)

Answer 1

Only selectors for input and p should be more specific via id or class so that extraneous elements are not processed

$('p').click(function(){
    var id = $(this).attr('id');
    $('input').val(id);
})
