DHTMLX Scheduler如何调用数据方法？

var scheduler = new dhx.Scheduler("scheduler_container", {
    // 配置项
});

scheduler.load("data.php");

scheduler.attachEvent("beforeLoad", function (id, url) {
    url += "?param1=value1&param2=value2";
    return true;
});

var data = {
    data: [
        { id: 1, text: "Event 1", start_date: "2022-01-01 09:00", end_date: "2022-01-01 10:00" },
        { id: 2, text: "Event 2", start_date: "2022-01-02 09:00", end_date: "2022-01-02 10:00" },
        // 其他日程数据...
    ]
};

scheduler.parse(data, "json");
