Menu
I the example below, use can open a modal, type a message and then send it... It would take 2 seconds to send the message... I would like to show a spinner (which is already working) but also I want to background of the modal to be greyed-out while spinner is showing...
$("#sendBtn").click(function() {
$('.sending-message-spinner').show();
setTimeout(function () {
$("#myModal").modal("hide");
}, 2000);
});textarea {
width: 100%;
height: 80px;
}
@keyframes loading {
0% {
transform: rotate(0);
}
100% {
transform: rotate(360deg);
}
}
.sending-message-spinner {
position: fixed;
text-align: center;
z-index: 20;
display: none;
width: 40px;
height: 40px;
border: 8px solid #B0B0B0;
border-radius: 50%;
border-top-color: #000;
animation: loading .75s linear infinite;

You can add a class to CSS and have your JS call it when the button is clicked. I added to CSS .myClass and set the opacity in there, then called it in JS with $("#myModal").addClass('myClass'); to add that class to myModal when the button is clicked. See here:
UPDATE: Here I did it with an overlay div inside myModal This will grey out the modal without making it transparent.
$("#sendBtn").click(function() {
$("#overlay").show();
$('.sending-message-spinner').show();
setTimeout(function () {
$("#myModal").modal("hide");
}, 2000);
});textarea {
width: 100%;
height: 80px;
}
@keyframes loading {
0% {
transform: rotate(0);
}
100% {
transform: rotate(360deg);
}
}
.sending-message-spinner {
position: fixed;
text-align: center;
z-index: 20;
display: none;
width: 64px;
height: 64px;
border: 8px solid #B0B0B0;
border-radius: 50%;
border-top-color: #000;
animation: loading .75s linear infinite;
}
#overlay {
position: fixed;
display: none;
width: 100%;
height: 100%;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-color: rgba(0,0,0,0.5);
z-index: 10;
