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）
