ajax 中的哈希更改事件 (javascript)

我实际上正在尝试使用户能够为页面添加书签，为此，我正在使用 javascript 的哈希更改事件。这是我的代码：

<script type="text/javascript">
function hashchk()
{
    hashvalue=window.location.hash;
    newhash="";
    for(var i=1;i<hashvalue.length;i++)
    {
        newhash=newhash+hashvalue[i];
    }
    if(hashvalue!="")
    {
        window.location.replace("viewme.php?ppid="+newhash);
    }
}
hashchk();
</script>

这里的一切都正常，除了当用户想要返回上一页时，他必须按浏览器的后退按钮两次而不是一次。

如果他在 http://www.example.com/abc.php#hello 第一次按后退按钮时，网址单独更改为 http://www.example.com/abc.php 但页面未加载。

但下次按下它时，它就正常了。我希望他们只按一次。提前致谢。

I am actually trying to enable user to bookmark pages and for this, i am using hash change event of javascript. Here is my code:

<script type="text/javascript">
function hashchk()
{
    hashvalue=window.location.hash;
    newhash="";
    for(var i=1;i<hashvalue.length;i++)
    {
        newhash=newhash+hashvalue[i];
    }
    if(hashvalue!="")
    {
        window.location.replace("viewme.php?ppid="+newhash);
    }
}
hashchk();
</script>

Everything here is working except for the fact that, when the user wants to go back to the previous page, he has to press the browser's back button 2 times rather than once.

if he is in http://www.example.com/abc.php#hello
on 1st pressing back button, url alone changes to http://www.example.com/abc.php but the page does not load.

But on pressing it the next time, it comes properly.
I want them to press it only once. Thanx in advance.

我对你的问题不太清楚。如果用户第一次访问带有哈希值的页面（例如#html3），那么您似乎正在尝试触发此功能，以便您可以使用服务器中的适当数据刷新他们的屏幕。这个问题本身似乎与 hashchange 事件没有直接关系。

测试此 HTML 后，我相信它可以按您的预期工作。每当页面加载并带有 #hash 时，它就会在查询字符串上使用它进行重定向。这也适用于页面刷新。

<script>
function hashchk()
{
    hashvalue=window.location.hash; 
     if(hashvalue!="") 
     { 
        window.location.replace("viewme.php?ppid="+hashvalue.substring(1)); 
    } 
}
hashchk();
</script>

I wasn't entirely clear on your question. It seems like you are trying to fire this if a user comes to a page for the first time with a hash on it (like #html3) so you can refresh their screen with the appropriate data from the server. The question itself doesn't seem directly related to the hashchange event.

After testing this HTML, I believe it works as you expect. Whenever the page loads and has a #hash on it it will redirect it with it on the query string. This will also work for page refreshes.

<script>
function hashchk()
{
    hashvalue=window.location.hash; 
     if(hashvalue!="") 
     { 
        window.location.replace("viewme.php?ppid="+hashvalue.substring(1)); 
    } 
}
hashchk();
</script>
