getjson什么都没发生

Question

Having troubles with the following code. At this point I'd like to see the alert but not even that is happening.

$.getJSON('demo.js',function(result){
        alert(1);
      $.each(result, function(i, field){
        $("div").append(field + " ");
      });
    });

demo.js looks like:

{ 
  "firstName": "John",
  "lastName": "Doe",
  "age": 25
}

That alert isn't even popping up. This is code taken from a web tutorial and it's not working for me. I'm pretty stumped. Any ideas?

Answer 1

For debug purpose, you can do

$.getJSON('demo.js',function(result) {
   console.log(result);
}).fail(function (j, t, e) {
   console.error(e);
});

But I think your problem is either invalid json or header.

Answer 2

In order to $.getJSON, you have to submit a json datatype

Using longhand $.ajax would work i believe if you were to omit datatype, but theres really no reason unless by your own restriction that demo sold be a js instead of a json file
