vue3 甘特圖（三）：甘特圖右側內容拖動展示內容
解決因多個專案週期跨度不同，在一頁螢幕裡展示不完全，需要透過拖動甘特圖下方的捲軸，去檢視對應時間段內的內容
拖拽滾動檢視，展示對應時間甘特圖
構思，透過監聽內容拖拽的距離，同時使捲軸滑動相同距離，從而達到效果。
//拖拽滾動檢視
const scrollInit = () => {
const nav = document.querySelectorAll('.gantt_task')[0]
const parNav = document.querySelectorAll('.gantt_hor_scroll')[0]
parNav.scrollLeft = 0
let flag
let downX
let scrollLeft
nav.addEventListener('mousedown', function (event) {
flag = true
downX = event.clientX // 獲取到點選的x下標
scrollLeft = this.scrollLeft // 獲取當前元素捲軸的偏移量
})
nav.addEventListener('mousemove', function (event) {
if (flag) {
let moveX = event.clientX
let scrollX = moveX - downX
parNav.scrollLeft = scrollLeft - scrollX
}
})
// 滑鼠抬起停止拖動
nav.addEventListener('mouseup', function () {
flag = false
})
// 滑鼠離開元素停止拖動
nav.addEventListener('mouseleave', function (event) {
flag = false
})
}
