自定义点击表格横向滚动指令v-tableDrag
main.js将directices.js引入即可
import Vue from 'vue'
Vue.directive('tableDrag', {
inserted: function(el) {
el = el.getElementsByClassName('el-table__body-wrapper')[0]
el.style.cursor = 'grab'
el.onmousedown = function() {
let gapX = event.clientX
let startX = el.scrollLeft
document.onmousemove = function(e) {
let x = e.clientX - gapX
el.scrollLeft = startX - x
return false
}
document.onmouseup = function() {
document.onmousemove = null
document.onmouseup = null
}
}
}
})
