 引入 <script src="../javaScript/ajaxfileupload.js"></script> 

<button class="btn btn-success" id="upload">上传文件</button>
 <input type="file" id="btnUpload" name="file" accept=".xls,.xlsx" style="display: none;" />
 <input type="hidden" id="filepath" />
<input type="hidden" id="filename" />
<span id="uploadfilename">未选择任何文件</span></li>

        $("#upload").bind("click", function () {
            //选择上传文件
            $("#btnUpload").click();
        });
