Loading div in front of bootstrap modal

Question

I'm using bootstrap and modals for partial views, I have a "loading" div to put in front of everything while getting the data. I can't put the loading div in front of the modal, already tried with z-index but still nothing.

This is my css:

.load {
position: absolute;
z-index: 500 !important;
height: 100%;
display: none;
border: 0;
padding: .5em 1em;
overflow: auto;
top: 0%;
left: 0%;
background: white;
width: 100%;
border: none;
opacity: 0.8;
}
.imagen_loading {
position: absolute;
z-index: 500 !important;
top: 35%;
left: 43%;
width: 300px;
height: 300px;
background: url('../../Content/img/gif/loader3.gif')
}

And this is my modal:

 <div class="modal fade" id="modal_aprobar_transferencia" data-target="#modal_aprobar_transferencia">
        <div class="modal-dialog">
            <div class="modal-content" style="overflow:auto; width:90% !important; height:90% !important;">
                <div class="modal-header orange">
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                        <span aria-hidden="true">&times;</span>
                    </button>
                    <h4 class="modal-title"><strong></strong>Transfers</h4>
                </div>
                <div class="modal-body">

                    @{
                        Html.RenderAction("lista_transferencias", "Almacen");
                    }

                </div>
            </div>
        </div>
    </div>

Edit:

<div class="container-fluid" style="padding-left:7em; padding-right:3em;">

<div id="loading" class="load">
    <div id="spinner" class="imagen_loading" style=""></div>
</div>

My partial views are mostly the same, tables and edits.

I'd appreciate any help.

Answer 1

The trick in here is data-backdrop="false" style="background-color: rgba(0, 0, 0, 0.5);" by removing the default backdrop and create a dummy one by setting background color of the dialog itself with some alpha.

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" data-backdrop="false" style="background-color: rgba(0, 0, 0, 0.5);">
<div class="modal-dialog" role="document">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal"
                aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <h4 class="modal-title" id="myModalLabel">Modal title</h4>
        </div>
        <div class="modal-body">...</div>
        <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
        </div>
    </div>
</div>

Notes: clicking on the background does not close the dialogue as is expected. Solution: So to achieve that you have to add some javascript code. Here is some example of how you can accomplish this.

$('.modal').click(function(event){
    $(event.target).modal('hide');
});

HTML: place this within your body tag

<div id="LoaderWindow">
    <div id="Loader"></div>
</div>

/* CSS for loading*/

.loader-window {
    width: 100%;
    height: 100%;
    position: fixed;
    z-index: 1051;
    background: rgba(54, 70, 93, 0.95);
}

.loader {
    position: absolute;
    top:50%;
    left:50%;
    border: 8px solid #f3f3f3;
    border-radius: 50%;
    border-top: 8px solid #5BFEC8;
    width: 60px;
    height: 60px;
    margin-top:-30px;
    margin-left:-30px;
    -webkit-animation: spin 2s linear infinite;
    animation: spin 2s linear infinite;
}

@-webkit-keyframes spin {
    0% { -webkit-transform: rotate(0deg); }
    100% { -webkit-transform: rotate(360deg); }
}

@keyframes spin {
    0% { transform: rotate(0deg); }
    100% { transform: rotate(360deg); }
}

You have to use jquery to add class.

function loader(
    operation
) {
    if (operation == 'add') {
        $('#LoaderWindow').addClass('loader-window');
        $('#Loader').addClass('loader');
    } else {
        $('#LoaderWindow').removeClass('loader-window');
        $('#Loader').removeClass('loader');
    }
}

loader('add') would be used when you request data and after received a response use loader('remove');

Answer 2

Try setting this styles to your loading div:

#loading {
    position: fixed;
    left: 0;
    top: 0;
    width: 100%;
    height: 100%;
    z-index: 9999;
    background: url(img/preloader.gif) center no-repeat #fff;
 }

Be advised, the loading <div> must be out of the modal <div>.

HTML

<div id="loading"></div>

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"></div>

Answer 3

When inspecting the modals within the Bootstrap (3 and 4) documentation, it looks like their default z-index is 1050. Did you try increasing the z-index of your loading div to something greater than 1050?
