「实战应用」如何用DHTMLX将上下文菜单集成到JavaScript甘特图中

// 引入DHTMLX Gantt和ContextMenu库
import { gantt, Gantt } from "dhtmlx-gantt";
import "dhtmlx-gantt/codebase/locale/locale_cn";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_marker.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_tooltip.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_grid_selection.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_palette.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_constraints.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_parent_tasks.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_export.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_timeline.js";
import "dhtmlx-gantt/codebase/ext/dhtmlxgantt_contextmenu.js";
 
// 初始化Gantt图表
gantt.init("gantt_here");
 
// 配置Gantt图表
gantt.config.locale = "cn";
gantt.config.open_splitted_panels = true;
gantt.config.dnd = {
    order: true
};
 
// 配置上下文菜单
gantt.config.context_menu = {
    items: [
        { text: "添加任务", action: function(e, task) { gantt.addTask(task); } },
        { text: "删除任务", action: function(e, task) { gantt.deleteTask(task.id); } },
        { text: "更新任务", action: function(e, task) { gantt.updateTask(task); } },
        { text: "取消选择", action: function(e, task) { gantt.clearSelection(); } }
    ]
};
 
// 模拟数据
var tasks = [
    { id: 1, text: "任务1", start_date: "2023-04-01", duration: 5 },
    { id: 2, text: "任务2", start_date: "2023-04-02", duration: 5 }
];
 
// 将数据加载到Gantt图表中
gantt.init(tasks);

这段代码演示了如何在DHTMLX Gantt中集成上下文菜单功能。首先，我们引入了必要的DHTMLX Gantt库和上下文菜单扩展。然后，我们初始化Gantt图表并配置了一些基本设置，包括本地化和开启分割面板。接着，我们配置了上下文菜单选项，定义了菜单项和它们的行为。最后，我们加载了一些模拟数据到Gantt图表中。
