js、jquery让滚动条到底部
jquery
$('body').scrollTop($('body')[0].scrollHeight); //把body换掉即可
//滚动条在Y轴上的滚动距离 function getScrollTop(){ var scrollTop = 0, bodyScrollTop = 0, documentScrollTop = 0; if(document.body){ bodyScrollTop = document.body.scrollTop; } if(document.documentElement){ documentScrollTop = document.documentElement.scrollTop; } scrollTop = (bodyScrollTop - documentScrollTop > 0) ? bodyScrollTop : documentScrollTop; return scrollTop; } //文档的总高度 function getScrollHeight(){ var scrollHeight = 0, bodyScrollHeight = 0, documentScrollHeight = 0; if(document.body){ bodyScrollHeight = document.body.scrollHeight; } if(document.documentElement){ documentScrollHeight = document.documentElement.scrollHeight; } scrollHeight = (bodyScrollHeight - documentScrollHeight > 0) ? bodyScrollHeight : documentScrollHeight; return scrollHeight; } //浏览器视口的高度 function getWindowHeight(){ var windowHeight = 0; if(document.compatMode == "CSS1Compat"){ windowHeight = document.documentElement.clientHeight; }else{ windowHeight = document.body.clientHeight; } return windowHeight; } window.onscroll = function(){ if(getScrollTop() + getWindowHeight() == getScrollHeight()){ alert("已经到最底部了!!"); } };
