检测后退按钮/哈希变化网址 [英] Detecting Back Button/Hash Change in URL
问题描述
我刚刚成立了我的新主页: http://ritter.vg 。我使用jQuery,但非常最低限度。
它加载全部采用AJAX网页 - 我把它设置为允许书签通过在URL中检测的哈希值。
I just set up my new homepage at http://ritter.vg. I'm using jQuery, but very minimally.
It loads all the pages using AJAX - I have it set up to allow bookmarking by detecting the hash in the URL.
//general functions
function getUrl(u) {
return u + '.html';
}
function loadURL(u) {
$.get(getUrl(u), function(r){
$('#main').html(r);
}
);
}
//allows bookmarking
var hash = new String(document.location).indexOf("#");
if(hash > 0)
{
page = new String(document.location).substring(hash + 1);
if(page.length > 1)
loadURL(page);
else
loadURL('news');
}
else
loadURL('news');
但我不能让后退和前进按钮的工作。
But I can't get the back and forward buttons to work.
有没有一种方法来检测时,后退按钮已经pssed $ P $(或检测时,散的变化),而不使用的setInterval循环?当我试图那些0.2 1秒超时,就挂我的CPU。
Is there a way to detect when the back button has been pressed (or detect when the hash changes) without using a setInterval loop? When I tried those with .2 and 1 second timeouts, it pegged my CPU.
推荐答案
使用 jQuery的hashchange事件的插件来代替。关于你提到的全AJAX导航,尝试有搜索引擎友好的AJAX 。否则,什么都不显示在浏览器页面的JavaScript限制。
Use the jQuery hashchange event plugin instead. Regarding your full ajax navigation, try to have SEO friendly ajax. Otherwise your pages shown nothing in browsers with JavaScript limitations.
