Download files using Ajax

Jquery Ajax functions only return the XML, text, JSON, HTML, and other types, and do not have the "stream" type. Therefore, we need to implement Ajax download, the corresponding Ajax function cannot be used for file download. However, you can use js to generate a form, use this form to submit parameters, and return "stream" type data. The page is not refreshed during implementation.

VaR Form = $ ("<form> "); // Define a form
Form. ATTR ("style", "display: none ");
Form. ATTR ("target ","");
Form. ATTR ("method", "Post ");
Form. ATTR ("action", "exportdata ");
VaR Input1 = $ ("<input> ");
Input1.attr ("type", "hidden ");
Input1.attr ("name", "exportdata ");
Input1.attr ("value ",( New Date (). getmilliseconds ());
$ ("Body"). append (form ); // Place forms in the Web
Form. append (input1 );

Form. Submit ();//Form submission
