我需要覆盖显示以上的第一个模式,而不是在后面。
$('#openBtn').click(function(){
$('#myModal').modal({show:true})
});
<a data-toggle="modal" href="#myModal" class="btn btn-primary">Launch modal</a>
<div class="modal" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div><div class="container"></div>
<div class="modal-body">

我试图改变。modal- background的z索引,但它变得一团糟。
在某些情况下,我在同一页上有两个以上的情态动词。
其他的解决方案在开箱即用时对我不起作用。我想可能是因为我使用的是Bootstrap(3.3.2)的最新版本....覆盖层出现在模态对话框的顶部。
我重构了一些代码,并注释掉了调整模式背景的部分。这解决了问题。
var $body = $('body');
var OPEN_MODALS_COUNT = 'fv_open_modals';
var Z_ADJUSTED = 'fv-modal-stack';
var defaultBootstrapModalZindex = 1040;
// keep track of the number of open modals
if ($body.data(OPEN_MODALS_COUNT) === undefined) {
$body.data(OPEN_MODALS_COUNT, 0);
}
$body.on('show.bs.modal', '.modal', function (event)
{
if (!$(this).hasClass(Z_ADJUSTED)) // only if z-index not already set
{
// Increment count & mark as being adjusted
$body.data(OPEN_MODALS_COUNT, $body.data(OPEN_MODALS_COUNT) + 1);
$(this).addClass(Z_ADJUSTED);
// Set Z-Index
$(this).css('z-index', defaultBootstrapModalZindex + (1 * $body.data(OPEN_MODALS_COUNT)));
//// BackDrop z-index (Doesn't seem to be necessary with Bootstrap 3.3.2 ...)
//$('.modal-backdrop').not( '.' + Z_ADJUSTED )
// .css('z-index', 1039 + (10 * $body.data(OPEN_MODALS_COUNT)))
// .addClass(Z_ADJUSTED);
}
});
$body.on('hidden.bs.modal', '.modal', function (event)
{
// Decrement count & remove adjusted class
$body.data(OPEN_MODALS_COUNT, $body.data(OPEN_MODALS_COUNT) - 1);
$(this).removeClass(Z_ADJUSTED);
// Fix issue with scrollbar being shown when any modal is hidden
if($body.data(OPEN_MODALS_COUNT) > 0)
$body.addClass('modal-open');
});
顺便说一句,如果你想在AngularJs中使用它,只需将代码放在模块的.run()方法中即可。
终于解决了。我对它进行了多种测试,效果很好。
以下是所有遇到同样问题的人的解决方案:
修改Modal.prototype.show函数(在bootstrap.js或modal.js中)
来自:
if (transition) {
that.$element[0].offsetWidth // force reflow
}
that.$element
.addClass('in')
.attr('aria-hidden', false)
that.enforceFocus()
TO:
if (transition) {
that.$element[0].offsetWidth // force reflow
}
that.$backdrop
.css("z-index", (1030 + (10 * $(".modal.fade.in").length)))
that.$element
.css("z-index", (1040 + (10 * $(".modal.fade.in").length)))
.addClass('in')
.attr('aria-hidden', false)
that.enforceFocus()
这是我发现的最好的方法:检查打开了多少个模态,并将模态和背景的z-index更改为更高的值。
A1rPun的答案在一个小的修改后完美地工作(Bootstrap 4.6.0)。我的名声不允许我评论,所以我会在网上回复。
我只是替换了。modal.show的每个。modal:visible。
因此,在打开多个情态动词时修复背景:
$(document).on('show.bs.modal', '.modal', function () {
var zIndex = 1040 + (10 * $('.modal.show').length);
$(this).css('z-index', zIndex);
setTimeout(function() {
$('.modal-backdrop').not('.modal-stack').css('z-index', zIndex - 1).addClass('modal-stack');
}, 0);
});
和,修复滚动条:
$(document).on('hidden.bs.modal', '.modal', function () {
$('.modal.show').length && $(document.body).addClass('modal-open');
});
我也遇到过类似的情况,经过一番研究,我找到了一个解决方案。虽然我不擅长JS,但我还是设法写下了一个小查询。

Bootstrap 5的解决方案(纯JS)。
@A1rPun的答案启发的解决方案。
// On modal open
document.addEventListener('show.bs.modal', function(e) {
// Get count of opened modals
let modalsCount = 1;
document.querySelectorAll('.modal').forEach(function(modalElement) {
if (modalElement.style.display == 'block') {
modalsCount++;
}
});
// Set modal and backdrop z-indexes
const zIndex = 1055 + 10 * modalsCount;
e.target.style.zIndex = zIndex;
setTimeout(() => {
const backdropNotStacked = document.querySelector('.modal-backdrop:not(.modal-stack)');
backdropNotStacked.style.zIndex = ('z-index', zIndex - 5);
backdropNotStacked.classList.add('modal-stack');
});
});
解释
循环所有可见的情态动词(你不能使用pseudoselector:visible,这只在jquery中)
计算新的z指数。Bootstrap 5的默认值是1055,因此:
默认值(1055)+ 10 *打开的模态数
将这个新的计算z-index设置为模态
标识背景(没有指定类的背景——在本例中是.modal-stack)
设置这个新的计算z-index -5为背景
添加类.modal-stack到背景,以防止在打开下一个模式时得到这个背景
