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。
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
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。
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);
}
});
});
