Using AJAX to dynamically change data from dropdown












0














I am trying to change the opacity of my graph bars dynamically. I have them currently telling the user to refresh the page which I don't want. How could I use AJAX to achieve something like this?



const opacitySlider = document.getElementById('opacity');

$('#opacity').on('input', function () {
$('.bars').css('opacity', $(this).val());
localStorage.setItem('opacity', opacitySlider.value);
checkAlert.innerHTML = 'Please click the refresh button or reload the page to make new changes.';
});

I don't quite understand what you want, as $('.bars').css('opacity', $(this).val()); should change the opacity if $(this).val() has a value between 0 and 1.



but if you want to make the change from ajax you just have to use the jQuery ajax function like



$('#opacity').on('input', function () {
$('.bars').css('opacity', $(this).val());
localStorage.setItem('opacity', opacitySlider.value);
});
$.ajax({
url : '/your/url',
method: 'GET',
success: function(response) {
//assuming you're retrieving the opacity from server
$('.bars').css('opacity', response.opacity);
}
})
