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>
</div>
</div>
</div>
</div>
<div class="modal" id="myModal2" data-backdrop="static">
<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">Second Modal title</h4>
</div><div class="container"></div>
<div class="modal-body">
Content for the dialog / modal goes here.
</div>
<div class="modal-footer">
<a href="#" data-dismiss="modal" class="btn">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>
</div>
</div>
</div>
</div>

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。
根据耶莫·拉默斯的建议，这似乎是一个更短的版本。即使是基本的动画，如淡入/淡出，甚至疯狂的蝙蝠侠报纸旋转。http://jsfiddle.net/ketwaroo/mXy3E/
$('.modal').on('show.bs.modal', function(event) {
var idx = $('.modal:visible').length;
$(this).css('z-index', 1040 + (10 * idx));
});
$('.modal').on('shown.bs.modal', function(event) {
var idx = ($('.modal:visible').length) -1; // raise backdrop after animation.
$('.modal-backdrop').not('.stacked').css('z-index', 1039 + (10 * idx));
$('.modal-backdrop').not('.stacked').addClass('stacked');
});
我的解决方案自举4，与无限深度的模态和动态模态工作。
$('.modal').on('show.bs.modal', function () {
var $modal = $(this);
var baseZIndex = 1050;
var modalZIndex = baseZIndex + ($('.modal.show').length * 20);
var backdropZIndex = modalZIndex - 10;
$modal.css('z-index', modalZIndex).css('overflow', 'auto');
$('.modal-backdrop.show:last').css('z-index', backdropZIndex);
});
$('.modal').on('shown.bs.modal', function () {
var baseBackdropZIndex = 1040;
$('.modal-backdrop.show').each(function (i) {
$(this).css('z-index', baseBackdropZIndex + (i * 20));
});
});
$('.modal').on('hide.bs.modal', function () {
var $modal = $(this);
$modal.css('z-index', '');
});
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。
Demo
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);
}
});
});
