Question

I have a jstree JQuery pluguin that I use with its “checkbox” plugin. I need to select checkbox programmatically and disable checkboxes, also programmatically.

How I can do that?

https://groups.google.com/forum/?fromgroups#!topic/jstree/wLokkEg3eCY%5B1-25%5D this I tried ind got no result.

My Jstree:

 var myTree = $(tree).jstree({
    "json_data": {
        "ajax": {
            type: "POST",
            async: true,
            "url": urlTree,
            // data: '{"longnames":"' + flag + '"}',

            data: function (n) {
                id = n.attr ? n.attr("id") : prefix + '0';
                reply = '{ id: "' + id + '"';
                //  if (dataJSON.length > 0) {
                //      reply = reply + ", " + dataJSON;
                //  }
                reply += ', longnames: "' + flag + '"';
                // reply += ", prefix: ";
                //  reply += (mutateIds != 1) ? '' : '"' + prefix + '"';
                reply += "}";

                return reply
            },
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            cache: false,
            success: function (msg) {

                return msg.d.data;
            },
            error: function () {
                // process error of ajax
                return false;
            }
        },
        //  "xsl": "flat",


    },
    "search": {
        "show_only_matches": true,
        "search_method": "jstree_contains"
    },
    "types": {
        "max_children": -2,
        "max_depth": -2,
        "default": {
            "valid_children": ["default"],
            "select_node": function (e) {
                this.toggle_node(e);
                return false;
            } 
        },
        "disabled" : { 
                  "check_node" : false, 
                  "uncheck_node" : false 
                }  
    },
    "cookies": {
        "save_opened": false
    },
    "checkbox":{
         "override_ui": "true",
        "real_checkboxes": "true"
    },
    "plugins": pluginsToUse
})

To check the node programmaticlly all you need to do is:

$('#tree').jstree('check_node','#id');

Here #id is the id of the node.
