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”——– 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>
