$(‘a[href*=#],area[href*=#]’).click(function() {
if (location.pathname.replace(/^//, ”) == this.pathname.replace(/^//, ”) && location.hostname == this.hostname) {
var $target = $(this.hash);
$target = $target.length && $target || $(‘[name=’ + this.hash.slice(1) + ‘]’);
if ($target.length) {
var targetOffset = $target.offset().top;
$(‘html,body’).animate({
scrollTop: targetOffset
},
1000);
return false;
}
}
