  • Bootstrap 文件上传插件 FileInput的使用问题

      在使用bootstrap的文件上传插件fileinput http://plugins.krajee.com/file-input的预览功能时,删除预览图片在 bootstrap 模态框中没有用,需要先点击移除,在点删除才有用

      问题对比:

           1.在正常页面中可以使用

      

     <input type="file" id="test" class="form-control inline-form-control"/>
    $(document).ready(function () {
            var url1 = 'http://upload.wikimedia.org/wikipedia/commons/thumb/e/e1/FullMoon2010.jpg/631px-FullMoon2010.jpg';
    
    
            $("#test").fileinput({
                initialPreview: [url1],
                initialPreviewAsData: true,
                initialPreviewConfig: [
                    {caption: "Moon.jpg", downloadUrl: url1, size: 930321,  "120px", key: 1}
                ],
                deleteUrl: "/watch/video/deleteimage",
                overwriteInitial: false,
                maxFileSize: 100,
                initialCaption: "The Moon and the Earth"
            });
         $("#test2").fileinput({
                initialPreview: [url1],
                initialPreviewAsData: true,
                initialPreviewConfig: [
                    {caption: "Moon.jpg", downloadUrl: url1, size: 930321,  "120px", key: 1}
                ],
                deleteUrl: "/watch/video/deleteimage",
                overwriteInitial: false,
                maxFileSize: 100,
                initialCaption: "The Moon and the Earth"
            });
    });

        点击删除,看到了删除请求

      

    2.同样的代码,将 input 放到modal中

      modal代码

      

    <div class="modal fade" id="editVideo" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel"
         aria-hidden="true">
        <div class="modal-dialog modal-lg" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h5 class="modal-title">修改视频评测</h5>
                    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                        <span aria-hidden="true">&times;</span>
                    </button>
                </div>
                <div class="modal-body" style="min-height: 260px;">
                    <div class="row" style="height: auto">
                       
                          <input type="file" class="form-control" name="editfile" id="test2">
                              
                    </div>
                </div>
                <div class="modal-footer">
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">关闭</button>
                    <button type="submit" class="btn btn-primary edit-confirm">确定</button>
                </div>
            </div>
        </div>
    </div>
