h5获取滚动条位置
methods:{
handleScroll: function () {
//变量scrollTop是滚动条滚动时,距离顶部的距离
var scrollTop = document.documentElement.scrollTop || document.body.scrollTop;
//变量windowHeight是可视区的高度
var windowHeight = document.documentElement.clientHeight || document.body.clientHeight;
//变量scrollHeight是滚动条的总高度
var scrollHeight = document.documentElement.scrollHeight || document.body.scrollHeight;
//滚动条到底部的条件
if (scrollTop + windowHeight == scrollHeight) {
this.page += 1;
this.getData();
//写后台加载数据的函数
console.log("距顶部" + scrollTop + "可视区高度" + windowHeight + "滚动条总高度" + scrollHeight);
}
}
},
mounted(){
window.addEventListener('scroll', this.handleScroll)
},
destroyed() {
window.removeEventListener("scroll", this.handleScroll);
},
或者是
window.onscroll = function () {
//变量scrollTop是滚动条滚动时,距离顶部的距离
var scrollTop = document.documentElement.scrollTop || document.body.scrollTop;
//变量windowHeight是可视区的高度
var windowHeight = document.documentElement.clientHeight || document.body.clientHeight;
//变量scrollHeight是滚动条的总高度
var scrollHeight = document.documentElement.scrollHeight || document.body.scrollHeight;
console.log(scrollTop);
//滚动条到底部的条件
if (scrollTop + windowHeight == scrollHeight) {
this.page += 1;
this.getData();
}
}
