IE10/11 Ajax XHR error - SCRIPT7002: XMLHttpRequest: Network Error 0x2ef3

Question

I\'ve been working on this problem for a few days and reaching out on this forum since I feel like I\'ve exhausted my options. I have a form hosted on a Drupal 7 website an

Answer 1

In my environment, I first copied/pasted some old codes to take use of. So the "contentType" was "application/json".

When I found out IE11 over windows 8 does NOT work in a very high probability, as long as I clicked submit button using my mouse. But I also found out the if I pressed the enter key in my keyboard, then it works just fine with IE11.

Note that my input elemnts and submit button were nested in a form element.

After struggling for a while, I came to this page, but didn't solve my problem, because I knew nothing about backend technologies. I was just a front-end guy with limited knowledge.

Then I tried a lot of modifications one by one. Suddenly the jQuery official API documents inspired me. I commented out the "contentType" parameter so that the "contentType" takes the default value, which is "application/x-www-form-urlencoded; charset=UTF-8". Then problem is solved.

Hope this will help.
