无需页面滚动即可修改location.hash [英] Modifying location.hash without page scrolling

问题描述

我们有一些页面使用ajax来加载内容，在某些情况下，我们需要深度链接到页面.与其链接到用户"并告诉人们单击设置"，不如将其链接到 user.aspx#settings

We've got a few pages using ajax to load in content and there's a few occasions where we need to deep link into a page. Instead of having a link to "Users" and telling people to click "settings" it's helpful to be able to link people to user.aspx#settings

为了使人们能够为我们提供指向各节的正确链接(用于技术支持等)，我将其设置为在单击按钮时自动修改URL中的哈希.当然，唯一的问题是，发生这种情况时，它还会将页面滚动到该元素.

To allow people to provide us with correct links to sections (for tech support, etc.) I've got it set up to automatically modify the hash in the URL whenever a button is clicked. The only issue of course is that when this happens, it also scrolls the page to this element.

是否可以禁用此功能?到目前为止，这是我目前的操作方式.

Is there a way to disable this? Below is how I'm doing this so far.

$(function(){
    //This emulates a click on the correct button on page load
    if(document.location.hash){
     $("#buttons li a").removeClass('selected');
     s=$(document.location.hash).addClass('selected').attr("href").replace("javascript:","");
     eval(s);
    }

    //Click a button to change the hash
    $("#buttons li a").click(function(){
            $("#buttons li a").removeClass('selected');
            $(this).addClass('selected');
            document.location.hash=$(this).attr("id")
            //return false;
    });
});

我曾希望return false;可以阻止页面滚动-但这只会使链接根本不起作用.因此，现在暂时将其注释掉，以便我进行导航.

I had hoped the return false; would stop the page from scrolling - but it just makes the link not work at all. So that's just commented out for now so I can navigate.

有什么想法吗?

推荐答案

我想我可能已经找到了一个相当简单的解决方案.问题在于URL中的哈希也是滚动到页面上的元素.如果我只是在哈希前面添加一些文本，那么现在它不再引用现有元素！

I think I may have found a fairly simple solution. The problem is that the hash in the URL is also an element on the page that you get scrolled to. if I just prepend some text to the hash, now it no longer references an existing element!

$(function(){
    //This emulates a click on the correct button on page load
    if(document.location.hash){
     $("#buttons li a").removeClass('selected');
     s=$(document.location.hash.replace("btn_","")).addClass('selected').attr("href").replace("javascript:","");
     eval(s);
    }

    //Click a button to change the hash
    $("#buttons li a").click(function(){
            $("#buttons li a").removeClass('selected');
            $(this).addClass('selected');
            document.location.hash="btn_"+$(this).attr("id")
            //return false;
    });
});

现在，URL显示为page.aspx#btn_elementID，它不是页面上的真实ID.我只是删除"btn_"并获取实际的元素ID

Now the URL appears as page.aspx#btn_elementID which is not a real ID on the page. I just remove "btn_" and get the actual element ID
