Concurrent Ajax Calls?

I need to call a particular PHP script on my server several times. As each call will take some time (e.g. about .5 seconds) and each call is independent of each other, I want to call the scripts concurrently. Right now, I have something like this:

$(document).ready(function() {

    $.ajax({
      url: 'main.php',
      method: 'POST',
      data: { foo: 'foo' },
      success: function(result) {
        console.log(result);
      }
    });

    $.ajax({
      url: 'main.php',
      method: 'POST',
      data: { bar: 'bar' },
      success: function(result) {
        console.log(result);
      }
    });

});

Instead of making these calls sequentially, I want to do them concurrently. How do I do that?

Not sure what issue you are experiencing but you are making concurrent AJAX calls because jQuery defaults to async: true. If it defaulted to false then it would be called SJAX lol

One issue which you might be experiencing would be a session handling lockup.

If main.php is using session_start() then it will simply queue the bar request until foo finishes. Or you can manually call session_write_close() to avoid the lockup.

Ajax requests are asynchronous by nature. Based on your example, each of the calls will be dispatched without waiting for the server's response

Set your async = true on your AJAX calls to make them asynchronous.

$.ajax({
    async: "true",
      url: 'main.php',
      method: 'POST',
      data: { foo: 'foo' },
      success: function(result) {
        console.log(result);
      }
    });

    $.ajax({
    async: "true",
      url: 'main.php',
      method: 'POST',
      data: { bar: 'bar' },
      success: function(result) {
        console.log(result);
      }
    });
