本文实例讲述了jQuery实现自动滚动到页面顶端的方法。分享给大家供大家参考。具体实现方法如下：

$(".scroll").click(function(event){ //prevent the default action for the click event event.preventDefault(); //get the full url - like mysitecom/index.htm#home var full_url = this.href; //split the url by # and get the anchor target //name - home in mysitecom/index.htm#home var parts = full_url.split("#"); var trgt = parts[1]; //get the top offset of the target anchor var target_offset = $("#"+trgt).offset(); var target_top = target_offset.top; //goto that anchor by setting the body scroll top to anchor top $('html, body').animate({scrollTop:target_top}, 500);});​

希望本文所述对大家的jQuery程序设计有所帮助。
