dhtmlx Gantt知识点1

鼠标放在任务上显示信息框：

<script src="../../codebase/ext/dhtmlxgantt_tooltip.js?v=5.2.0"></script>

//添加竖线：
<script src="../../codebase/ext/dhtmlxgantt_marker.js?v=5.2.0"></script>
var date_to_str = gantt.date.date_to_str(gantt.config.task_date);
//今日竖线    
var today = new Date(2018, 3, 5);
    gantt.addMarker({
        start_date: today,
        css: "today",
        text: "Today",
        title: "Today: " + date_to_str(today)
    });
//开始竖线
    var start = new Date(2018, 2, 28);
    gantt.addMarker({
        start_date: start,
        css: "status_line",
        text: "Start project",
        title: "Start project: " + date_to_str(start)
    });

//日期格式规则
gantt.config.date_scale = "%F, %Y"；

gantt.config.scale_unit = ""；

设置始终：
gantt.config.start_date = new Date(2018, 02, 31); 
gantt.config.end_date = new Date(2018, 03, 09);
