多模态叠加

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> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.0/css/bootstrap.min.css" /> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.0.0/js/bootstrap.min.js"></script>

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。

当前回答

每次你运行sys。showModal函数增加z-index并将其设置为新的模态。

function system() {

    this.modalIndex = 2000;

    this.showModal = function (selector) {
        this.modalIndex++;

        $(selector).modal({
            backdrop: 'static',
            keyboard: true
        });
        $(selector).modal('show');
        $(selector).css('z-index', this.modalIndex );       
    }

}

var sys = new system();

sys.showModal('#myModal1');
sys.showModal('#myModal2');

Bootstrap 4.5的简单解决方案

.modal.fade {
  background: rgba(0, 0, 0, 0.5);
}

.modal-backdrop.fade {
  opacity: 0;
}

在modal.js中添加全局变量

var modalBGIndex = 1040; // modal backdrop background
var modalConIndex = 1042; // modal container data

//添加变量modal .prototype. background

var e    = $.Event('show.bs.modal', { relatedTarget: _relatedTarget })

modalConIndex = modalConIndex + 2; // add this line inside "Modal.prototype.show"

that.$element
    .show()
    .scrollTop(0)
that.$element.css('z-index',modalConIndex) // add this line after show modal 

if (this.isShown && this.options.backdrop) {
      var doAnimate = $.support.transition && animate

      modalBGIndex = modalBGIndex + 2; // add this line increase modal background index 2+

this.$backdrop.addClass('in')
this.$backdrop.css('z-index',modalBGIndex) // add this line after backdrop addclass

每个模态都应该有一个不同的id，每个链接都应该指向不同的模态id。所以应该是这样的:

<a href="#myModal" data-toggle="modal">
...
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>
...
<a href="#myModal2" data-toggle="modal">
...
<div id="myModal2" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>
...

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);
       }
    });
});

没有脚本解决方案，只使用css给你有两层情态，设置第2个情态为更高的z索引

.second-modal { z-index: 1070 }

div.modal-backdrop + div.modal-backdrop {
   z-index: 1060; 
}
