Question

My problem is that i wanna use post data outside it’s function, example:

$(function() {
  var s = 'something ';
  $.post('ajax.php', {option: 'test'}, function(data) {
    s += data; // data: 'hello world';
  });
  alert(s); // output: 'something ';
});

my expected result is ‘something hello world’.
how can i deal with this?
Thanks

Use $.ajax with async:false, I assume the data is coming as content-type:json/application e.g.

var s = 'something ';
$.ajax({
      url: "ajax.php",
      type: "POST",
      data: ({option: 'test'}),
      dataType: "json",
      async:false,
      success: function(msg){
         s += msg.data;//msg={data: "hello world"}
      }
   }
);
alert(s);
