「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.date_format = "%Y-%m-%d";
gantt.config.open_split_tasks = true;
gantt.config.autosize = true;
gantt.config.scale_height = 600;
gantt.config.min_column_width = 30;
gantt.config.duration_unit = "day";
gantt.config.work_time = true;
gantt.config.correct_work_time = true;
gantt.config.zoom_on_scroll = false;
gantt.config.min_grid_size = 20;
gantt.config.fbar = [{
    text: "导入",
    handler: importData
}, {
    text: "导出",
    handler: exportData
}];
 
// 创建数据
gantt.init("gantt_here");
gantt.parse(getGanttData());
 
// 初始化上下文菜单
gantt.addContextMenu();
 
// 其他函数和数据定义略...

在这个例子中，我们导入了必要的DHTMLX Gantt和ContextMenu库，并初始化了Gantt图表。我们还配置了Gantt的设置，并创建了一些数据。最后，我们调用gantt.addContextMenu()来初始化上下文菜单。这个简化的代码片段展示了如何将上下文菜单集成到Gantt图表中。
