下面给大家分享两种方法来介绍Vue 实时监听窗口变化 windowresize，具体内容如下所示：
方法一：
First-step : 定义变量
data(){
return{
formLabelWidth : '123px'
}
},
Second-step: 根据生命周期 在mounted 中绑定 窗口变化
mounted(){
const that = this
window.onresize = () => {
return (() => {
window.screenWidth = document.body.clientWidth
that.screenWidth = window.screenWidth
})()
}
},
Third-step: 绑定监听 watch
watch: {
screenWidth (val) {
if (!this.timer) {
this.screenWidth = val
this.timer = true
let that = this
setTimeout(function () {
// that.screenWidth = that.$store.state.canvasWidth
console.log(that.screenWidth)
// that.init()
that.timer = false
}, 400)
}
}
},
方法二：在vue.2x里面时候，mounted 里面可以直接挂载 window.onresize事件。全局监听
mounted(){
window.onresize = () => {
return (() => {
this.handleLableWidth();
})()
}
this.handleLableWidth();
},
完全可以做到检测窗口变化
