Post formdata via XMLHttpRequest object in JS ? ( cross browser)

Question

Im trying to post a form data in js :

I have this code :

var formData = new FormData();
  formData.append(\"username\", \"Groucho\");
  formData.ap         


        

Answer 1

You didn't say which version of IE you're using. The formData object is not supported in IE9 or lower. XMLHTTPRequest2 (which contains the formData object) should be supported in IE10 (http://caniuse.com/xhr2)

Cross-browser AJAX file upload is very hard to do right now. You could try building your own form header/boundaries in Javascript (see answer here: XMLHttpRequest POST multipart/form-data) but, personally, I don't believe it is worth the effort.
