Sagar, you can simply use $.getJSON() method in jQuery to perform an AJAX call to your external JSON file and later iterate through it using $.each() method.

Example


$.getJSON("https://www.json-generator.com/api/json/get/cgkYrpeouq?indent=2", function(data) {
  $.each(data, function(i, field) {
    //$("div").append(field + " ");
    console.log(field);
  });
});

Comments
  • What do you mean by external JSON ?
  • That depends on where exactly that external JSON is stored and how.
  • Its store in same location like $.getJSON('menu.json', function (data) { }); or how to cal from ajax..
  • api.jquery.com/jQuery.getJSON
  • Thanks Alex. I modified for loop to each function.
  • Please don't use W3Schools as a reference. Their articles are often outdated and sometimes just plain wrong. MDN is far more comprehensive and accurate: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…
  • oh, I didn't know that. well, I don't use that site usually, but just came up to the top of google result, so.. well, good to know. thanks.
  • No problem. That's the issue with their site really, they appear very highly in Google searches even though they spread inaccurate information.
