vue3 甘特图(二):gantt时间轴切换
1.固定时间轴缩放级别
gantt.config.scale_unit = "month"; //时间轴单位 gantt.config.step = 1;//单位数 gantt.config.date_scale = "%Y年%M";//时间轴展现方式
2.动态改变时间轴缩放
点击不同按钮,切换时间轴状态
2.1 配置时间轴参数
levels里可配置多个级别。
scales展示时间轴对应多少行,下的format可自定展现方式,css属性方法可判断是否为轴,给周末添加上高亮属性。

const zoomConfig = { levels: [ { name: 'day', scale_height: 60, scales: [{ unit: 'day', step: 1, format: '%d %M' }] }, { name: 'week', scale_height: 60, scales: [ { unit: 'week', step: 1, format: function (date) { let dateToStr = gantt.date.date_to_str('%m-%d') let endDate = gantt.date.add(date, -6, 'day') let weekNum = gantt.date.date_to_str('%W')(date) //第几周 return dateToStr(endDate) + ' 至 ' + dateToStr(date) } }, { unit: 'day', step: 1, format: '%d', // + "周%D" css: function (date) { if (date.getDay() == 0 || date.getDay() == 6) { return 'day-item weekend weekend-border-bottom' } else { return 'day-item' } } } ] }, { name: 'month', scale_height: 60, min_column_width: 18, scales: [ { unit: 'month', format: '%Y-%m' }, { unit: 'day', step: 1, format: '%d', css: function (date) { if (date.getDay() == 0 || date.getDay() == 6) { return 'day-item weekend weekend-border-bottom' } else { return 'day-item' } } } ] }, { name: 'quarter', height: 60, min_column_width: 110, scales: [ { unit: 'quarter', step: 1, format: function (date) { let yearStr = new Date(date).getFullYear() + '年' let dateToStr = gantt.date.date_to_str('%M') let endDate = gantt.date.add(gantt.date.add(date, 3, 'month'), -1, 'day') return yearStr + dateToStr(date) + ' - ' + dateToStr(endDate) } }, { unit: 'week', step: 1, format: function (date) { let dateToStr = gantt.date.date_to_str('%m-%d') let endDate = gantt.date.add(date, 6, 'day') let weekNum = gantt.date.date_to_str('%W')(date) return dateToStr(date) + ' 至 ' + dateToStr(endDate) } } ] }, { name: 'year', scale_height: 50, min_column_width: 150, scales: [ { unit: 'year', step: 1, format: '%Y年' }, { unit: 'month', format: '%Y-%m' } ] } ] }
2.2 初始化时间轴配置
gantt.ext.zoom.init(zoomConfig) //配置初始化扩展 gantt.ext.zoom.setLevel('month') //切换到指定的缩放级别
2.3 改变时间轴
const changeTime = () => { gantt.ext.zoom.setLevel(data.timeState) }
2.4 周末或特殊日期高亮
.weekend { background: #ff9e2f; color: #fff; }
