Ajax file upload successfully resolves browser compatibility issues _ajax related

Ajaxfileupload control is very useful, but found that the results of uploading files for browser processing, IE will not, Google and Firefox will be processed, and Google and Firefox after the results are not the same, here for the above three browser compatibility adjustment.
