JavaScript Show popup on mouseover for each table row show popup mouseover javascript,show popup on mouseover,show popup

When dealing with multiple elements of the same kind (in your case text in multiple rows in the table) always use classes and not IDs in your markup. And then bind the functions accordingly in Javascript.

To help you understand better, IDs are unique identifiers. Like your passport number uniquely identifies you as a person. And only one person in the world has that number. Similarly IDs should be unique for each element. Classes on the other hand are used to identify similar entities. For example, a class of Economics students will share some common properties (like the all study Macroeconomics from 9am-10m). Thus in your case, the elements should have the same class name (because the hover effect on each of them) will be a common property.

So your HTML would change like this to use classes instead of IDs

.....
<td class="pizzaname">
    <%= product.nome_pizza%>
       <div class="popup" style=" height: 50px;">
.....

And your JS would then be

  $('.pizzaname').hover(function() {
    $(this).find('.popup').show();
  }, function() {
    $(this).find('.popup').hide();
  });
