我正在为部分 View 使用 Bootstrap 和模态，我有一个“正在加载”的 div 在获取数据时放在所有内容的前面。我不能将加载 div 放在模式前面，已经尝试使用 z-index 但仍然没有。
这是我的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')
}
这是我的模式:
<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">×</span>
</button>
<h4 class="modal-title"><strong></strong>Transfers</h4>
</div>
<div class="modal-body">
@{
Html.RenderAction("lista_transferencias", "Almacen");
}
</div>
</div>
</div>
</div>

我的部分 View 大部分相同，表格和编辑。
如果有任何帮助，我将不胜感激。
最佳答案
这里的技巧是 data-backdrop="false"style="background-color: rgba(0, 0, 0, 0.5);"通过删除默认背景并通过使用一些 alpha 设置对话框本身的背景颜色来创建虚拟背景。
<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">×</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>
注意:单击背景不会按预期关闭对话。 解决方案:因此，要实现这一点，您必须添加一些 javascript 代码。以下是如何完成此操作的一些示例。
$('.modal').click(function(event){
$(event.target).modal('hide');
});
HTML:将其放在您的正文标签中
<div id="LoaderWindow">
<div id="Loader"></div>
</div>
/* 加载CSS*/
.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); }
}
你必须使用 jquery 来添加类。
function loader(
operation
) {
if (operation == 'add') {
$('#LoaderWindow').addClass('loader-window');
$('#Loader').addClass('loader');
} else {
$('#LoaderWindow').removeClass('loader-window');
$('#Loader').removeClass('loader');
}
}
loader('add') 将在您请求数据时使用，在收到响应后使用 loader('remove');
