最好的方法是给每个部分一个 ID。如果你想要干净的 URL,你可以使用 Jquery 创建一个函数
这是我在单页网站中使用的一个
var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body', 'document', 'window');
//console.log(scrollElem);
$('a[href*=#]').each(function() {
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {
var $target = $(this.hash), target = this.hash;
if (target) {
//console.log('Target: ' + target + ' offset: ' + targetOffset);
$(this).click(function(event) {
var targetOffset = $target.offset().top;
event.preventDefault();
$(scrollElem).animate({scrollTop: targetOffset}, 1000, function() {
//console.log($(scrollElem).scrollTop());
location.hash = target;
$(scrollElem).animate({scrollTop: targetOffset}, 0);
});
});
}
}
});
// use the first element that is "scrollable"
function scrollableElement(els) {
for (var i = 0, argLength = arguments.length; i <argLength; i++) {
var el = arguments[i],
$scrollElement = $(el);
if ($scrollElement.scrollTop()> 0) {
return el;
} else {
$scrollElement.scrollTop(1);
var isScrollable = $scrollElement.scrollTop()> 0;
//console.log(el + ': ' + $scrollElement.scrollTop());
$scrollElement.scrollTop(0);
if (isScrollable) {
return el;
}
}
}
return 'body';
}
