Open PDF File in New Tab in UI5 Applicaiton on Internet Explorer

Hello Experts,

I have a requirement where i need to display PDF file in a new tab.

I have data in base 64 that i am getting from Backend into the Gateway server.( i can get in xstring format as well)

Now when i try to use-

1.  window.open("data:application/pdf," + escape(a) , "_blank");

     a will have the pdf data

      This works well in Chrome but fails in Internet Explorer.

What i need exactly is like webdynpro Framework where by using below we used to get pdf loaded in New tab which will have native PDF print and download options:-

  cl_wd_runtime_services=>attach_file_to_response(

*                     EXPORTING i_filename      = 'File_pdf

                      EXPORTING i_filename       = lv_file_name

                                i_content                   = lv_content

                                i_mime_type              = 'application/pdf' "

                                i_in_new_window       = abap_true

                                i_inplace                    = abap_true ).

Please let me know Guys how to achieve this functionality.I need solution that works in IE11.

Thanks in advance,

Sujit
