vue 实现项目进度甘特图-编程知识

项目需求：

实现以1天、7天、30天为周期（周期根据筛选条件选择），展示每个项目不同里程碑任务进度。

项目在Vue-Gantt-chart: 使用Vue做数据控制的Gantt图表基础上进行了改造。

有需要的小伙伴也可以直接引入插件，自己修改。

我是直接把甘特图封装成了组件，结构如下图：

首先，安装插件

npm install v-gantt-chart

引入插件（我是全局引入的）

import vGanttChart from 'v-gantt-chart';Vue.use(vGanttChart);

代码如下：

index.js

<template><div class="container"><v-gantt-chart:startTime="times[0]":endTime="times[1]":cellWidth="cellWidth":cellHeight="cellHeight":timeLines="timeLines":titleHeight="titleHeight":scale="Number(1440 * scale)":titleWidth="titleWidth"showCurrentTime:hideHeader="hideHeader":dataKey="dataKey":arrayKeys="arrayKeys":scrollToTime="scrollToTime":scrollToPostion="positionA"@scrollLeft="scrollLeftA"customGenerateBlocks:datas="ganttData"><templatev-slot:block="{data,getPositonOffset,getWidthAbout2Times,isInRenderingTimeRange,startTimeOfRenderArea,endTimeOfRenderArea,isAcrossRenderingTimeRange}"><divclass="gantt-block-item"v-for="(item, index) in data.gtArray"v-if="isInRenderingTimeRange(item.start) ||isInRenderingTimeRange(item.end) ||isAcrossRenderingTimeRange(item.start, item.end)":key="item.id":style="{left: getPositonOffset(item.start) + 'px',width: getWidthAbout2Times(item.start, item.end) + 'px',height: judgeTime(data.gtArray) ?

页面中使用

<div><ganttChart:ganttData="ganttArr":scaleData="scaleData":scrollToTime="scrollToTime"@nodeEventClick="nodeEventClick"@panelDbClick="panelDbClick"></ganttChart>
</div>

import moment from 'moment';
import ganttChart from './components/ganttChart/index.vue';export default {components: { ganttChart },data(){return{ganttArr: [],scaleData: 10080,scrollToTime: moment().subtract(4, 'days').format('YYYY-MM-DD'),}},methods: {// 点击甘特图node节点nodeEventClick(item) {// 执行自己的逻辑},// 双击甘特图左侧标题panelDbClick(item) {//执行自己的逻辑}}}

以上就是实现甘特图的全部过程，欢迎大佬们指教。
