How to include JSON data in javascript synchronously without parsing?

rated 0 times [ 156] [ 2] / answers: 1 / hits: 61975 / 14 Years ago, sun, november 7, 2010, 12:00:00

I want to load a JSON file from my own server containing an array into a javascript Object variable.

I would like to do it at the beginning of page load in a synchronous way because data is needed during page load.

I managed to use jQuery.getJSON but this is asynch ajax and it seems a little overkill.

Is there a way to load JSON in a synch way without doing your own parsing?
(more or less like using a <script language=JavaScript src=MyArray.json></script>)

Thanks in advance for any help, hope it makes sense since I am a javascript newbie.

getJSON() is simply shorthand for the ajax() function with the dataType:'json' set. The ajax() function will let you customize a lot about the request.

$.ajax({

  url: 'MyArray.json',

  async: false,

  dataType: 'json',

  success: function (response) {

    // do stuff with response.

  }

});

You still use a callback with async:false but it fires before it execution continues on from the ajax call.
