BootStrap的两种模态框方式

bootstrap的弹出层

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”――C 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>
