mounted() {
this.dragControllerDiv(this.$refs.resize, this.$refs.resizeHandle)
},
methods: {
dragControllerDiv: function(resizeBox, resizeHandle) {
resizeBox.style.width = this.resizeConf.width + 'px'
// 鼠标按下事件
resizeHandle.onmousedown = e => {
const resizeWidth = resizeBox.offsetWidth
const startX = e.clientX // 水平坐标
// 鼠标拖动事件
document.onmousemove = ev => {
const moveX = ev.clientX
const moveLen = resizeWidth + (moveX - startX)
if (this.resizeConf.widthRange[0] <= moveLen && this.resizeConf.widthRange[1] >= moveLen) {
resizeBox.style.width = moveLen + 'px'
