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">
Content for the dialog / modal goes here.
<br>
<br>
<br>
<br>
<br>
<a data-toggle="modal" href="#myModal2" class="btn btn-primary">Launch modal</a>
</div>
<div class="modal-footer">
<a href="#" data-dismiss="modal" class="btn">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>

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。
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。

$('.ingredient-item').on('click', function(e){
e.preventDefault();
var content = $(this).find('p').text();
$('.modal-body').html(content);
});
适用于开启/关闭多种模式
jQuery(function()
{
jQuery(document).on('show.bs.modal', '.modal', function()
{
var maxZ = parseInt(jQuery('.modal-backdrop').css('z-index')) || 1040;
jQuery('.modal:visible').each(function()
{
maxZ = Math.max(parseInt(jQuery(this).css('z-index')), maxZ);
});
jQuery('.modal-backdrop').css('z-index', maxZ);
jQuery(this).css("z-index", maxZ + 1);
jQuery('.modal-dialog', this).css("z-index", maxZ + 2);
});
jQuery(document).on('hidden.bs.modal', '.modal', function ()
{
if (jQuery('.modal:visible').length)
{
jQuery(document.body).addClass('modal-open');
var maxZ = 1040;
jQuery('.modal:visible').each(function()
{
maxZ = Math.max(parseInt(jQuery(this).css('z-index')), maxZ);
});
jQuery('.modal-backdrop').css('z-index', maxZ-1);
}
});
});

解决方案灵感来自@YermoLamers和@Ketwaroo的回答。
背景z指数修正
这个解决方案使用setTimeout,因为当事件show.bs.modal被触发时,.modal- background不会被创建。
$(document).on('show.bs.modal', '.modal', function() {
const zIndex = 1040 + 10 * $('.modal:visible').length;
$(this).css('z-index', zIndex);
setTimeout(() => $('.modal-backdrop').not('.modal-stack').css('z-index', zIndex - 1).addClass('modal-stack'));
});
这适用于页面上创建的每个.modal(即使是动态模态)
背景瞬间覆盖了之前的模式
例子jsfiddle
z - index
如果你不喜欢硬编码的z指数,你可以计算页面上的最高z指数,如下所示:
const zIndex = 10 +
Math.max(...Array.from(document.querySelectorAll('*')).map((el) => +el.style.zIndex));
滚动条修正
如果页面上的某个模态超出了浏览器的高度,那么关闭第二个模态时就不能在其中滚动。要解决这个问题,添加:
$(document).on('hidden.bs.modal', '.modal',
() => $('.modal:visible').length && $(document.body).addClass('modal-open'));
版本
这个解决方案是用3.1.0 - 3.3.5引导程序测试的

我通过jhay优化了解决方案,它还支持关闭和打开相同或不同的对话框,例如,从一个细节数据向前或向后跨步到另一个细节数据。
(function ($, window) {
'use strict';
var MultiModal = function (element) {
this.$element = $(element);
this.modalIndex = 0;
};
MultiModal.BASE_ZINDEX = 1040;
/* Max index number. When reached just collate the zIndexes */
MultiModal.MAX_INDEX = 5;
MultiModal.prototype.show = function (target) {
var that = this;
var $target = $(target);
// Bootstrap triggers the show event at the beginning of the show function and before
// the modal backdrop element has been created. The timeout here allows the modal
// show function to complete, after which the modal backdrop will have been created
// and appended to the DOM.
// we only want one backdrop; hide any extras
setTimeout(function () {
/* Count the number of triggered modal dialogs */
that.modalIndex++;
if (that.modalIndex >= MultiModal.MAX_INDEX) {
/* Collate the zIndexes of every open modal dialog according to its order */
that.collateZIndex();
}
/* Modify the zIndex */
$target.css('z-index', MultiModal.BASE_ZINDEX + (that.modalIndex * 20) + 10);
/* we only want one backdrop; hide any extras */
if (that.modalIndex > 1)
$('.modal-backdrop').not(':first').addClass('hidden');
that.adjustBackdrop();
});
};
MultiModal.prototype.hidden = function (target) {
this.modalIndex--;
this.adjustBackdrop();
if ($('.modal.in').length === 1) {
/* Reset the index to 1 when only one modal dialog is open */
this.modalIndex = 1;
$('.modal.in').css('z-index', MultiModal.BASE_ZINDEX + 10);
var $modalBackdrop = $('.modal-backdrop:first');
$modalBackdrop.removeClass('hidden');
$modalBackdrop.css('z-index', MultiModal.BASE_ZINDEX);
}
};
MultiModal.prototype.adjustBackdrop = function () {
$('.modal-backdrop:first').css('z-index', MultiModal.BASE_ZINDEX + (this.modalIndex * 20));
};
MultiModal.prototype.collateZIndex = function () {
var index = 1;
var $modals = $('.modal.in').toArray();
$modals.sort(function(x, y)
{
return (Number(x.style.zIndex) - Number(y.style.zIndex));
});
for (i = 0; i < $modals.length; i++)
{
$($modals[i]).css('z-index', MultiModal.BASE_ZINDEX + (index * 20) + 10);
index++;
};
this.modalIndex = index;
this.adjustBackdrop();
};
function Plugin(method, target) {
return this.each(function () {
var $this = $(this);
var data = $this.data('multi-modal-plugin');
if (!data)
$this.data('multi-modal-plugin', (data = new MultiModal(this)));
if (method)
data[method](target);
});
}
$.fn.multiModal = Plugin;
$.fn.multiModal.Constructor = MultiModal;
$(document).on('show.bs.modal', function (e) {
$(document).multiModal('show', e.target);
});
$(document).on('hidden.bs.modal', function (e) {
$(document).multiModal('hidden', e.target);
});}(jQuery, window));
尝试在bootply上将以下内容添加到JS中
$('#myModal2').on('show.bs.modal', function () {
$('#myModal').css('z-index', 1030); })
$('#myModal2').on('hidden.bs.modal', function () {
$('#myModal').css('z-index', 1040); })
解释:
在摆弄了属性之后(使用Chrome的开发工具),我意识到任何低于1031的z-index值都会把东西放在背景后面。
所以通过使用bootstrap的模态事件句柄,我将z-index设置为1030。如果显示#myModal2,如果隐藏#myModal2,则将z-index设置为1040。
