JSON with languages

Here is the demo of the long and short JSON format for multilanguage trees. You need to set the languages option. In the buttons code, you can see how to get an instance - either by using reference and focused.

$(function () { 
    $("#l_json").tree({
        languages : [ "en", "bg" ],
        data : { 
            type : "json",
            opts : {
                static : [
                    { 
                        // the short format demo
                        data : { "en" : "A node", "bg" : "Нодче" },
                        // here are the children
                        children : [
                            { data : { "en" : "Child node 1", "bg" : "Дете 1" } },
                            { data : { "en" : "Child node 2", "bg" : "Дете 2" } }
                        ]
                    },
                    { 
                        attributes : { "id" : "li.node.id" }, 
                        // this is the long data format
                        data : { 
                            bg : {
                                title : "удри баце", 
                                attributes : { "href" : "http://jstree.com" } 
                            },
                            en : {
                                title : "Long format demo", 
                                attributes : { "href" : "http://jstree.com" } 
                            }
                        } 
                    }
                ]
            }
        }
    });
});
