Implementing automatic loading of data when the browser scroll bar reaches the bottom based on javascript_javascript skills
No more nonsense, I will just post the js code for you.
<!DOCTYPE html>
<html>
<head>
<script src="jquery-...js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var range = ; //距下边界长度/单位px
var elemt = ; //插入元素高度/单位px
var maxnum = ; //设置加载最多次数
var num = ;
var totalheight = ;
var main = $("#content"); //主体元素
$(window).scroll(function () {
var srollPos = $(window).scrollTop(); //滚动条距顶部距离(页面超出窗口的高度)
//console.log("滚动条到顶部的垂直高度: "+$(document).scrollTop());
//console.log("页面的文档高度 ："+$(document).height());
//console.log('浏览器的高度：'+$(window).height());
totalheight = parseFloat($(window).height()) + parseFloat(srollPos);//滚动条当前位置距顶部距离+浏览器的高度
if (($(document).height() - totalheight) <= range && num != maxnum) {//页面底部与滚动条底部的距离<range
main.append("<div style='border:px solid tomato;margin-top:px;color:#ac" + (num % ) + (num % ) + ";height:" + elemt + "' >hello world" + srollPos + "---" + num + "</div>");
main.append("<div style='border:px solid tomato;margin-top:px;color:#ac" + (num % ) + (num % ) + ";height:" + elemt + "' >hello world" + srollPos + "---" + num + "</div>");
num++;
}
});
});
</script>
</head>
<body>
<div id="content" style="height:px">
<div id="follow">this is a scroll test;<br /> 页面下拉自动加载内容</div>
<div style='border:px solid tomato;margin-top:px;color:#ac;height:'>hello world test DIV</div>
</div>
</body>
</html>ps: How does native JavaScript trigger scroll bar events?
<script>
window.onscroll = function(){
var scrollT = document.documentElement.scrollTop||document.body.scrollTop;
var scrollH = document.documentElement.scrollHeight||document.body.scrollHeight;
var clientH = document.documentElement.clientHeight||document.body.clientHeight
//console.log(scrollT +"+"+scrollH+"+"+clientH);
if(scrollT == scrollH - clientH){
console.log("到底部了");
}else if(scrollT == 0){
console.log("到顶部了");
}
}
</script>
