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。

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>
...

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; 
}

在我的案例中，这个问题是由一个浏览器扩展引起的，它包括bootstrap.js文件，其中show事件处理了两次，并且添加了两个modal- background div，但是当关闭modal时，只删除了其中一个。

发现通过在chrome的body元素中添加子树修改断点，并跟踪添加了modal- background div。

使用CSS进行Z-index和模态背景校正

.modal.fade {
  z-index: 10000000 !important;
  background: rgba(0, 0, 0, 0.5);
}
.modal-backdrop.fade {
  opacity: 0;
}

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。
