I am just started with dhtmlx gantt and I have a problem:
1- I get the dhtmlx.gantt working like a charm. It updates and saves to MySQL database, where I can list and see the new tasks and delete existing tasks.
2- When I want to manipulate a task, say, change the text or date, retrieving the information from the json object, it is empty.
gantt.config.xml_date = "%Y-%m-%d %H:%i";
gantt.init("gantt_here");
gantt.load("data.php");//loads data to Gantt from the database
var dp = new gantt.dataProcessor("data.php");
dp.init(gantt);
retrieved = gantt.serialize().tasks;
console.log(retrieved);
var task = gantt.getTask(2);
console.log(task);
When I load the data.php on the browser, I get the full data:
{ “data”:[{“id”:“1”,“start_date”:“2013-04-01 00:00:00”,“duration”:“11”,“text”:“Um”,“progress”:“0.6”,“sortorder”:“1”,“parent”:“0”},{“id”:“2”,“start_date”:“2013-04-03 00:00:00”,“duration”:“5”,“text”:“Dois”,“progress”:“1”,“sortorder”:“2”,“parent”:“1”},{“id”:“3”,“start_date”:“2013-04-02 00:00:00”,“duration”:“7”,“text”:“Tres”,“progress”:“0.5”,“sortorder”:“0”,“parent”:“1”},{“id”:“4”,“start_date”:“2013-04-03 00:00:00”,“duration”:“2”,“text”:“Quatro”,“progress”:“1”,“sortorder”:“0”,“parent”:“3”},{“id”:“5”,“start_date”:“2013-04-04 00:00:00”,“duration”:“3”,“text”:“Cinco”,“progress”:“0.8”,“sortorder”:“0”,“parent”:“3”},{“id”:“6”,“start_date”:“2013-04-05 00:00:00”,“duration”:“4”,“text”:“Seis”,“progress”:“0.2”,“sortorder”:“0”,“parent”:“3”}], “collections”: {“links”:[{“id”:“1”,“source”:“1”,“target”:“2”,“type”:“1”},{“id”:“2”,“source”:“1”,“target”:“3”,“type”:“1”},{“id”:“3”,“source”:“3”,“target”:“4”,“type”:“1”},{“id”:“4”,“source”:“4”,“target”:“5”,“type”:“0”},{“id”:“5”,“source”:“5”,“target”:“6”,“type”:“0”}]}}
But when I want to see the gantt.getTask(2), it returns undefined.
It puzzles me, for the data.php and rendering of the gantt chart shows it has the data I want to see. Where is it?
Please help.
