jQuery each not last element

jQuery code snippets to loop through elements but not the last one. Could be useful for doing something with elements but not the last one. Also maybe a selector could be used something like:

.not(":last")

It ads the values of the select boxes on the page to an array and then uses the .concat() function to join the values together as a string.

var  controlitems = $('select');
    controlfilters = [],
    controlitemslength = controlitems.length;
controlitems.each(function (i,v)
{
   var filtervalue = $(this).val();

   if (filtervalue !== "")
   {
      controlfilters.push(filtervalue);
   }
});
console.log([].concat(controlfilters));

Output ids

Frequently Asked Questions (FAQs) about jQuery Element

What is the purpose of the .last() method in jQuery?

The .last() method in jQuery is used to select the last element in a group of selected elements. It is particularly useful when you want to apply a specific action or style to only the last element in a group. For example, you might want to highlight the last item in a list or apply a different style to the last row in a table. The .last() method makes it easy to select and manipulate this element without having to know its exact position in the group.

How does the .last-selector work in jQuery?

The .last-selector in jQuery is used in conjunction with the .last() method to select the last element in a group. It works by filtering out all elements except for the last one. This can be useful when you want to apply a specific action or style to the last element in a group, but you don’t know its exact position. The .last-selector makes it easy to select this element and apply the desired action or style.

For example, you might want to change the color of all paragraphs in a document, or hide all images on a page. The .each() method makes it easy to perform these actions without having to select and manipulate each element individually.
