plupload似乎没有上传文件在IE 9。它适用于其他浏览器

In our project we are using plupload to upload a single excel file. This is working in all the browsers except IE9. On click of the upload link the file dialog box is displayed but nothing happens when tried to open the excel. Below is the code for reference and any help to solve this will be much appreciated. Thanks in advance!In our project we are using plupload to upload
