Vue实时获取页面宽高
export default {
name: 'page-index',
data(){
return{
windowWidth: document.documentElement.clientWidth, //实时屏幕宽度
windowHeight: document.documentElement.clientHeight, //实时屏幕高度
}
},
methods: {
},
// <!--在watch中监听实时宽高-->
watch: {
windowHeight (val) {
let that = this;
console.log("实时屏幕高度：",val, that.windowHeight );
},
windowWidth (val) {
let that = this;
console.log("实时屏幕宽度：",val, that.windowHeight );
}
},
mounted() {
var that = this;
// <!--把window.onresize事件挂在到mounted函数上-->
window.onresize = () => {
return (() => {
window.fullHeight = document.documentElement.clientHeight;
window.fullWidth = document.documentElement.clientWidth;
that.windowHeight = window.fullHeight; // 高
that.windowWidth = window.fullWidth; // 宽
})()
};
},
}
