Is it possible to set async:false to $.getJSON call

You need to make the call using $.ajax() to it synchronously, like this:

$.ajax({
  url: myUrl,
  dataType: 'json',
  async: false,
  data: myData,
  success: function(data) {
    //stuff
    //...
  }
});

This would match currently using $.getJSON() like this:

$.getJSON(myUrl, myData, function(data) { 
  //stuff
  //...
});

Both answers are wrong. You can. You need to call

$.ajaxSetup({
async: false
});

before your json ajax call. And you can set it to true after call retuns ( if there are other usages of ajax on page if you want them async )


I think you both are right. The later answer works fine but its like setting a global option so you have to do the following:

    $.ajaxSetup({
        async: false
    });

    //ajax call here

    $.ajaxSetup({
        async: true
    });
