Hi,

I have this json data I need to filter/parse out data so it can be fed to the JsTree.
What I need from this json data is the content of the property2.

[
'property1':'abc',
'property2': [

{ 'text': 'john doe', 'age':'29', 'id':'123', 'uri': 'xxxxx'},
{ 'text': 'jane doe', 'age':'22', 'id':'122', 'uri': 'xxxxx'},
{ 'text': 'joe doe', 'age':'12', 'id':'121', 'uri': 'xxxxx'}
]
'property12':'bcc'
]

Open in new window


Need this section:
[

{ 'text': 'john doe', 'age':'29', 'id':'123', 'uri': 'xxxxx'},
{ 'text': 'jane doe', 'age':'22', 'id':'122', 'uri': 'xxxxx'},
{ 'text': 'joe doe', 'age':'12', 'id':'121', 'uri': 'xxxxx'}
]

You do it like this: http://jsbin.com/OfUdElA/2/edit?js,output

var myjson = {
  'property1':'abc',
  'property2': [
  { 'text': 'john doe', 'age':'29', 'id':'123', 'uri': 'xxxxx'},
  { 'text': 'jane doe', 'age':'22', 'id':'122', 'uri': 'xxxxx'},
  { 'text': 'joe doe', 'age':'12', 'id':'121', 'uri': 'xxxxx'}
  ],
    'property12':'bcc'
};

$(document).ready(function () { 
  $('#jstree2').jstree({ 'core' : {
    'data' : myjson.property2
  } });
});

JSON stands for "Javascript Object Notation" and is just a javascript object.  It's a term given to an object that has a particular format.  As for the jsTree they stipulate that "your JSON must look like [this]" to work with our plugin (which is just another javascript object)

In fact everything in javascript inherits from the javascript object.

eg

// an array
var myarray = [];
myarray['first'] = [1,2,3,4,5];
console.log(myarray.first); // can be written in dot notation like an object

So an array is an extension of an object with it's own specific methods and properties eg .length .indexOf() - however you can extend the object (scroll to "Create new methods")if you need to do more with it
