Question

I’m making a jsonp request with jquery.ajax() like this:

var cep = 99999999;
$.ajax({
    url: "http://cep.paicon.com.br/jsonp/"+ cep +"?callback=addressFunction",
    dataType: 'jsonp',
    crossDomain: true,
    jsonp: false
})

When there alright, the requested page call my callback function normally.

But, in some situations, the requested page don’t return anything.

How can i handle this error, since it won’t call any callback function?

Thanks!

(Sorry for my poor English)

Answer 1

You can set a timeout on your $.ajax() call, and handle the lack of response via that mechanism.

$.ajax({
  url: "http://cep.paicon.com.br/jsonp/"+ cep +"?callback=addressFunction",
  type: "GET",
  dataType: "jsonp",
  timeout: 2000,
  success: function(response) { alert(response); },
  error: function(x, t, m) {
      if(t==="timeout") {
          alert("got timeout");
      } else {
          alert(t);
      }
  }
});​
