jquery ajax error {“readyState”:0,“responseText”:“”,“status”:0,“statusText”:“error”}

Question

I am trying to do an ajax request

$.ajax({
  type: \"post\",
  url: \"download.php\",
  error: function(data, status, err){
           alert(JSON.stringify(d         


        

Answer 1

I was getting the same error:

"readyState: 0"
"responseText: undefined"
"status: 0"
"text status: error"
"error: "

In my case, one Firefox Browser works perfectly and another Firefox Browser with the same version was giving me this error without even making the ajax call.

The solution was to disable an Adblocker Add-On in my browser.
