Bootstrap3 模态框使用实例

时间：2021-07-09 08:28:31|栏目：JavaScript代码|点击：次

不支持同时打开多个模态框

务必尽量将HTML代码放置在模态框的body位置以避免其他组件影响模态框

*autofocus 对于模态框无效, 需要自己调用 $('#myModal').on('shown.bs.modal', function () {
 $('#myInput').focus()
})*

实例

静态

<div class="modal fade" tabindex="-1" role="dialog">
 <div class="modal-dialog" role="document">
 <div class="modal-content">
  <div class="modal-header">
  <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <h4 class="modal-title">Modal title</h4>
  </div>
  <div class="modal-body">
  <p>One fine body&hellip;</p>
  </div>
  <div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
  <button type="button" class="btn btn-primary">Save changes</button>
  </div>
 </div><!-- /.modal-content -->
 </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

动态

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
 Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
 <div class="modal-dialog" role="document">
 <div class="modal-content">
  <div class="modal-header">
  <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <h4 class="modal-title" id="myModalLabel">Modal title</h4>
  </div>
  <div class="modal-body">
  ...
  </div>
  <div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
  <button type="button" class="btn btn-primary">Save changes</button>
  </div>
 </div>
 </div>
</div>

可选尺寸

<!-- Large modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-lg">Large modal</button>
<div class="modal fade bs-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel">
 <div class="modal-dialog modal-lg" role="document">
 <div class="modal-content">
  ...
 </div>
 </div>
</div>
<!-- Small modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">Small modal</button>
<div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
 <div class="modal-dialog modal-sm" role="document">
 <div class="modal-content">
  ...
 </div>
 </div>
</div>

禁用fade

<div class="modal" tabindex="-1" role="dialog" aria-labelledby="...">
 ...
</div>

使用栅格系统

仅需在body中使用 .rows

<div class="modal fade" tabindex="-1" role="dialog" aria-labelledby="gridSystemModalLabel">
 <div class="modal-dialog" role="document">
 <div class="modal-content">
  <div class="modal-header">
  <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <h4 class="modal-title" id="gridSystemModalLabel">Modal title</h4>
  </div>
  <div class="modal-body">
  <div class="row">
   <div class="col-md-4">.col-md-4</div>
   <div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
  </div>
  <div class="row">
   <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
   <div class="col-md-2 col-md-offset-4">.col-md-2 .col-md-offset-4</div>
  </div>
  <div class="row">
   <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
  </div>
  <div class="row">
   <div class="col-sm-9">
   Level 1: .col-sm-9
   <div class="row">
    <div class="col-xs-8 col-sm-6">
    Level 2: .col-xs-8 .col-sm-6
    </div>
    <div class="col-xs-4 col-sm-6">
    Level 2: .col-xs-4 .col-sm-6
    </div>
   </div>
   </div>
  </div>
  </div>
  <div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
  <button type="button" class="btn btn-primary">Save changes</button>
  </div>
 </div><!-- /.modal-content -->
 </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

使用方法

通过data属性

<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

通过JavaScript调用

$('#myModal').modal(options)

参数

名称	类型	默认值	描述
backdrop	boolean 或字符串 ‘static'	true	设置为 static 时, 在点击屏幕时不会关闭
keyboard	boolean	true	键盘上的 esc 键被按下时关闭模态框
show	boolean	true	模态框初始化之后就立即显示出来

方法

模态框激活

.modal(options)

$('#myModal').modal({
 keyboard: false
})

模态框触发手动打开或者关闭

触发在 shown.bs.modal 以及 hidden.bs.modal 事件之前

.modal('toggle')

手动打开模态框

触发在 shown.bs.modal 之前

$('#myModal').modal('show')

手动隐藏模态框

触发在 hidden.bs.modal 之前

$('#myModal').modal('hide')

事件

按照时间先后顺序分别为 show.bs.modal shown.bs.modal hide.bs.modal hidden.bs.modal

调用方式

$('#myModal').on('hidden.bs.modal', function (e) {
 // do something...
})
