jQuery-单击时如何将锚点滚动到页面顶部? [英] jQuery - How to scroll an anchor to the top of the page when clicked?

问题描述

我在div元素中有一个链接列表，单击链接时，我正在使用dropcontent.js将内容加载到另一个div中.我现在想添加一些代码，将单击的链接滚动到浏览器窗口的顶部.

I have a list of links in div elements and I am using dropcontent.js to load content into another div when a link is clicked. I would now like to add some code which scrolls the clicked link to the top of the browser window.

列表中的每个项目的HTML都是这样的:

HTML is like this for each item in the list:

<div class="work">
    <h3><a class="scroll" href="project2.html">Project 2</a></h3>
    <div class="projectIntro">
        <p>This is some intro text for project 2</p>
    </div>
    <div class="pictures"></div>
</div>

我发现了一些在单击链接时滚动到ID的教程(通过将href设置为要滚动到的div的ID-不幸的是，我无法执行此操作，因为我的href实际上是一个单独的html页面尽管它使用dropcontent将其加载到当前页面中.

I have found tutorials for scrolling to an ID when a link is clicked (by making the href the ID of the div you want to scroll to - unfortunately I can't do this as my href is actually a separate html page even though it is using dropcontent to load it into the current page.

我还找到了一个用于在页面加载时滚动到特定ID的教程，但是没有一个简单地说明当单击给定类的锚点时，将其滚动到浏览器窗口顶部的情况.

I also found a tutorial for scrolling to a particular ID on page load, but none that simply say when an anchor of a given class is clicked, scroll it to the top of the browser window.

有人可以帮我解决这个问题吗?谢谢.

Can someone help me out with this one please? thanks.

更新:

我使用以下代码使滚动工作正常:

I have got the scroll working using the following code:

$('.work a').click(function() {
         $('html,body').animate({scrollTop: $(this).offset().top}, 500);
         }); 

但是，我的dropcontent.js不再起作用...我想是因为我在同一单击上发生了2个函数...我希望先加载内容，然后滚动.

However, my dropcontent.js is no longer working... I think because I have 2 functions occuring on the same click... I would like the content to load first, then scroll.

这是我的dropcontent.js

here is my dropcontent.js

$('.work a').click(function(event) {
event.preventDefault();

var parent = $(this).parents(".work");
var content_holder = parent.children(".pictures");

if (parent.hasClass("selected_work")) {
  close_other();
  return;
}

close_other();

parent.addClass("selected_work");
content_holder.load(this + " #content .work");

$('.selected_work img').attr("src", "images/arrow_close.gif");

});


function close_other() {

var selected_work = $('.selected_work');

selected_work.children('.pictures').empty();    
$('.selected_work img').attr("src", "images/arrow_open.gif");
selected_work.removeClass("selected_work")
}

});

因此，现在我只需要集成这2位代码即可使它们一起工作...到目前为止，我还没有走运-如果我添加了scroll(动画)函数，则load函数将停止工作. ..

So now I just need to integrate these 2 bits of code to get them working together... so far no I have had no luck doing this - if I add the scroll (animate) function, the load function stops working...

更新2

原来是导致问题的其他原因-我现在可以正常工作了！

Turns out it was something else which was causing the problem - I now have it working!
