了解data-dismiss属性在Bootstrap中的工作原理 [英] Understanding how data-dismiss attribute works in Bootstrap
问题描述
我是Bootstrap的新手,我遇到了这个例子的问题:
I'm new to Bootstrap and i'm facing problem with this example:
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
根据我的理解 data-dismiss =modal
属性应该关闭模式,如果你点击它,但我不明白它在幕后的工作原理。我查看了官方文档: http://getbootstrap.com/javascript/#modals-examples但是没有解释。
As per my understanding data-dismiss="modal"
attribute should close the modal if you click on it, but i don't understand how it works behind the scene. I checked the official documentation at: http://getbootstrap.com/javascript/#modals-examples but there's no explaination.
推荐答案
隐藏功能在 modal.js $中实现c $ c>以这种方式。
The hiding functionality is implemented in the modal.js
in this way.
this.$element.on('click.dismiss.bs.modal', '[data-dismiss="modal"]', $.proxy(this.hide, this))
基本上它只是找到具有 data-dismiss
属性的元素以及 modal
的值。点击它会隐藏这些元素。
Basically it's just finding the elements that have the attribute of data-dismiss
and the value of modal
. Upon click it will hide these elements.
