bootstrap弹出层的多种触发方式

bootstrap弹出层有多种触发方式，以下是我用到的几种方式：

1.方法一：button中属性触发

注意：button中的data-target内容应该和要和弹出层中的id保持一致
data-target=”#mymodal-data”——? id=”mymodal-data”

<!--在button上绑定触发弹出层的属性-->
 <button class="btn btn-primary delete" data-toggle="modal"
  data-target="#mymodal-data" data-whatever="@mdo">
  修改
</button>

<!-- 模态弹出窗内容 -->
<div class="modal" id="mymodal-data" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
 <div class="modal-dialog">
 <div class="modal-content">
  <div class="modal-header">
  <button type="button" class="close" data-dismiss="modal">
   <span aria-hidden="true">×</span>
   <span class="sr-only">Close</span>
  </button>
  <h4 class="modal-title">弹出层标题</h4>
  </div>
  <div class="modal-body">
  <p>弹出层主体内容</p>
  </div>
  <div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
  <button type="button" class="btn btn-primary">保存</button>
  </div>
 </div>
 </div>
</div>

结果：

2.方法二：通过js绑定

注意：将button的id和弹出层的id分别赋给 $m_btn和$modal，当$m_btn被点击后$modal弹出。

<button class="btn btn-info" type="button" id="y-modalBtnAdd" > <label >添加</label></button>


<!-- 模态弹出窗内容 -->
<div class="modal" id="y-myModalAdd" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
 <div class="modal-dialog">
 <div class="modal-content">
  <div class="modal-header">
  <button type="button" class="close" data-dismiss="modal">
   <span aria-hidden="true">×</span>
   <span class="sr-only">Close</span>
  </button>
  <h4 class="modal-title">弹出层标题</h4>
  </div>
  <div class="modal-body">
  <p>通过js绑定button和弹出层触发</p>
  </div>
  <div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
  <button type="button" class="btn btn-primary">保存</button>
  </div>
 </div>
 </div>
</div>
<!--js代码-->
<script type="text/javascript">
 $(function(){
 // dom加载完毕
 var $m_btn = $('#y-modalBtnAdd'); //y-modalBtnAdd是button的id
 var $modal = $('#y-myModalAdd'); //y-myModalAdd是弹出的遮罩层的id，通过这两个id进行绑定
 $m_btn.on('click', function(){
  $modal.modal({backdrop: 'static'});
 });
 });
 </script>

结果：

3.方法三：点击表格一行，弹出弹出层

动态给tr标签加弹出的触发属性

<!--表格-->
<table class="table table-bordered " style="width: 400px">
 <thead>
 <tr>
  <th>一</th>
  <th>二</th>
  <th>三</th>
 </tr>
 </thead>
 <tbody class="tableBody">
 <tr>
  <td>one</td>
  <td>two</td>
  <td>three</td>
 </tr>
 <tr>
  <td>four</td>
  <td>five</td>
  <td>six</td>
 </tr>
 </tbody>
</table>

<!-- 模态弹出窗内容 -->
<div class="modal" id="mymodal-data" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel" aria-hidden="true">
 <div class="modal-dialog">
 <div class="modal-content">
  <div class="modal-header">
  <button type="button" class="close" data-dismiss="modal">
   <span aria-hidden="true">×</span>
   <span class="sr-only">Close</span>
  </button>
  <h4 class="modal-title">弹出层标题</h4>
  </div>
  <div class="modal-body">
  <p>点击表格一行内容，弹出弹出层</p>
  </div>
  <div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
  <button type="button" class="btn btn-primary">保存</button>
  </div>
 </div>
 </div>
</div>


<!--js代码-->
<script type="text/javascript">
 $(function () {
 $(".tableBody>tr").each(function () {
  $(this).on("click",function () {
  $(this).attr({"data-toggle":"modal","data-target":"#mymodal-data","data-whatever":"@mdo"});

  })
 });
 });
</script>

结果：

bootstrap的弹出层在整个屏幕的上半部分，可以将它居中显示。（方法二可以让弹出层居中显示）

$(function(){
 // dom加载完毕
 var $m_btn = $('#y-modalBtnAdd'); y-modalBtnAdd是button的id
 var $modal = $('#y-myModalAdd'); y-myModalAdd是弹出的遮罩层的id，通过这两个id进行绑定 
 // 测试 bootstrap 居中 ，bootstrap的弹出层默认是左右居中，上下则是偏上，此代码将弹出层上下也居中了，但是会抖
   动一下
 $modal.on('shown.bs.modal', function(){
  var $this = $(this);
  var $modal_dialog = $this.find('.modal-dialog');
  var m_top = ( $(document).height() - $modal_dialog.height() )/2;
  $modal_dialog.css({'margin': m_top + 'px auto'});
 });
 });
</script>
