您可以使用 javascript 和 jquery 来设置窗口的滚动位置,并使用 cookie 来存储要滚动到的位置。在带有搜索结果的页面的 javascript 中,您可能会有如下内容:
var COOKIE_NAME = "scrollPosition";
$(document).ready( function() {
// Check to see if the user already has the cookie set to scroll
var scrollPosition = getCookie(COOKIE_NAME);
if (scrollPosition.length > 0) {
// Scroll to the position of the last link clicked
window.scrollTo(0, parseInt(scrollPosition, 10));
}
// Attach an overriding click event for each link that has a class named "resultLink" so the
// saveScrollPosition function can be called before the user is redirected.
$("a.resultLink").each( function() {
$(this).click( function() {
saveScrollPosition($(this));
});
});
});
// Get the offset (height from top of page) of the link element
// and save it in a cookie.
function saveScrollPosition(link) {
var linkTop = link.offset().top;
setCookie(COOKIE_NAME, linkTop, 1);
}
// Boring cookie helper function
function getCookie(name) {
if (document.cookie.length > 0) {
c_start = document.cookie.indexOf(name + "=");
if (c_start != -1) {
c_start = c_start + name.length + 1;
c_end = document.cookie.indexOf(";", c_start);
if (c_end ==- 1) c_end = document.cookie.length;
return unescape(document.cookie.substring(c_start, c_end));
}
}
return "";
}
// Another boring cookie helper function
function setCookie(name, value, expiredays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + expiredays);
document.cookie = name + "=" + escape(value) +
((expiredays==null) ? "" : ";expires=" + exdate.toGMTString());
}
这假设您的搜索结果链接具有class="resultLink"
.
