Mastering the art of incorporating live JavaScript search functionality that updates in real-time as the user continues typing on the same

Trying to implement a JavaScript search feature to find a div within the same page. The current code being used for the search query display is:

$('.form-search').on('submit',function(){return false;});
$('.form-search .btn').on('click', function(e){
    var query = $.trim($(this).prevAll('.search-query').val()).toLowerCase();
    $('div.staff-container .bold').each(function(){
         var $this = $(this);
         if($this.text().toLowerCase().indexOf(query) === -1)
             $this.closest('div.staff-container').fadeOut();
        else $this.closest('div.staff-container').fadeIn();
    });
});

A demonstration with HTML and CSS can be found here:

The goal is to display the div while the user is typing. The concept of using a refresh function is known, but struggling with understanding the JavaScript language. Learning as a beginner student.

Answer №1

To enhance the functionality of your Search button and dynamically update search results while typing in the text input, some refactoring is required. The following code snippet demonstrates how this can be achieved:

function updateResults() {
    var query = $.trim($('.search-query').val()).toLowerCase();
    $('div.staff-container .bold').each(function(){
         var $this = $(this);
         if($this.text().toLowerCase().indexOf(query) === -1)
             $this.closest('div.staff-container').fadeOut();
        else $this.closest('div.staff-container').fadeIn();
    });
}

$('.form-search').on('submit',function(){return false;});
$('.form-search .btn').on('click', updateResults);
$('.search-query').on('input', updateResults);

Answer №2

Are you looking for something specific? Instead of relying on a click event, consider using the 'input' event.

$('.form-search .search-query').on('input', function(e){ ... });

Answer №3

Instead of using the click() function, try using the keyup() function on the searchfield to trigger the action.
