我使用下面的代碼來滾動使用jQuery到錨點:jQuery的滾動錨(像素減去一定金額)
$(document).ready(function() {
function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}
var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body');
$('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) {
var targetOffset = $target.offset().top;
$(this).click(function(event) {
event.preventDefault();
$(scrollElem).animate({scrollTop: targetOffset}, 400, function() {
location.hash = target;
});
});
}
}
});
// 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;
$scrollElement.scrollTop(0);
if (isScrollable) {
return el;
}
}
}
return [];
}
});
反正讓它滾動到錨但減去一組量像素? (在我的情況,我想它去-92px)
感謝您的幫助。

他們如何相似?我要通過jquery滾動到每個錨點,當它們靠近頁面頂部時,鏈接的內容要滾動。代碼是非常不同的。 – John 2012-07-06 15:31:54
唯一的區別是您要滾動到哪個選擇器和偏移量。查看接受的答案,並用所需的選擇器替換'#id',並用所需的偏移量替換'100'。 – robbrit 2012-07-06 15:58:50
