angular上传文件组件 `ng-file-upload` IE11点击没有反应,如何解决？

把 默认的button标签改成a标签即可

<button class="btn btn-success btn-upload">
    <i class="glyphicon glyphicon-file"></i>
    <span class="ng-scope"> 选择文件</span>
    <input type="file" nv-file-select uploader="uploader" multiple />
</button>

改成:

<a href="javascript:;" class="btn btn-success btn-upload">
    <i class="glyphicon glyphicon-file"></i>
    <span class="ng-scope"> 选择文件</span>
    <input type="file" nv-file-select uploader="uploader" multiple />
</a>
