Render pdf using JQuery from a HttpHandler

Render pdf using JQuery from a HttpHandler

hi,

I have an application in which i have implemented an HTTP handler. I m calling this handler with jquery from my aspx button click. I have written code for the handler to return a PDF file. I want the browser to prompt for open or save option when i click the button. My code is rendering something like this 

%PDF-1.3 3 0 obj <> endobj 4 0 obj <> stream ...
this is my code for calling the HTTP handler where i have the method  for creating a PDF 
function pdf_report() {
        $
.ajax({
            type
:"POST",
            url
: "Handlers/pdf_Handler.ashx",
            contentType
: "application/json; charset=utf-8",
            success
: OnComplete,
            error
: OnFail
        
});
    
}
help me for opening this pdf file in client side in my browser when i click html control button in my asp page.
