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>

我试着改变z-index.modal-backdrop但它会变得一团糟。

背景z指数修正

此解决方案使用setTimeout因为.modal-backdrop事件时未创建show.bs.modal被触发了。

$(document).on('show.bs.modal', '.modal', function () {
    var zIndex = 1040 + (10 * $('.modal:visible').length);
    $(this).css('z-index', zIndex);
    setTimeout(function() {
        $('.modal-backdrop').not('.modal-stack').css('z-index', zIndex - 1).addClass('modal-stack');
    }, 0);
});
  • 这适用于每一个.modal在页面上创建(甚至是动态MODALS)
  • 背景立即覆盖前一个模态。

var zIndex = Math.max.apply(null, Array.prototype.map.call(document.querySelectorAll('*'), function(el) {
  return +el.style.zIndex;
})) + 10;

滚动条修复

如果页面上有超过浏览器高度的模式,则在关闭第二个模式时不能在其中滚动。若要修复此问题,请添加:

$(document).on('hidden.bs.modal', '.modal', function () {
    $('.modal:visible').length && $(document.body).addClass('modal-open');
});

解决方案自动工作在任意深度的堆栈模式,脚本源代码:

$(document).ready(function() {

    $('.modal').on('hidden.bs.modal', function(event) {
        $(this).removeClass( 'fv-modal-stack' );
            $('body').data( 'fv_open_modals', $('body').data( 'fv_open_modals' ) - 1 );
        });

    $('.modal').on('shown.bs.modal', function (event) {
        // keep track of the number of open modals
        if ( typeof( $('body').data( 'fv_open_modals' ) ) == 'undefined' ) {
            $('body').data( 'fv_open_modals', 0 );
        }

        // if the z-index of this modal has been set, ignore.
        if ($(this).hasClass('fv-modal-stack')) {
            return;
        }

        $(this).addClass('fv-modal-stack');
        $('body').data('fv_open_modals', $('body').data('fv_open_modals' ) + 1 );
        $(this).css('z-index', 1040 + (10 * $('body').data('fv_open_modals' )));
        $('.modal-backdrop').not('.fv-modal-stack').css('z-index', 1039 + (10 * $('body').data('fv_open_modals')));
        $('.modal-backdrop').not('fv-modal-stack').addClass('fv-modal-stack'); 

    });        
});
