问题标签 [slidedown]

有人知道为什么<div>选择 bin 之一时它会跳到顶部吗？我已经尝试了所有方法，但它不起作用（至少在 Chrome 中）。

这是我的脚本：

这是HTML：

Some of the pages of my site are extremely sluggish in IE8. The pages with lots of content load slowish in all browsers but slower in IE8. I assume they load slow to begin with because there is a lot of procedural PHP and database queries.

But my main concern is how lumberingly slow these pages are after they load in ie8. There are some jQuery slidedown effects and I'm wondering if ie8 just sucks at rendering them.

Here is a page with very little content: http://searchfornutrition.com/?pageid=topic&topicid=acai

The slidedown from the buttons work fine and the jQuery is fast/normal.

Now here is a page with lots of content: http://searchfornutrition.com/?pageid=topic&topicid=vitamin_d

The slidedown from the buttons is sluggish.

I've checked another computer with IE8 and it's the same. I did all the unique programming for this site and I'm no expert. Doing this site was how I learned everything I know about web development so if it's not IE8 then it's probably me.

thanks for any help you can give.

Edit:

I just tried out the network tab on Chrome dev tools and it was very helpful as far as why my pages load so slowly in the first place. Some of the unnecessary .css links take seconds to load but mostly it's the document itself. Sometimes it can take up to 30 seconds alone, which means my code isn't efficient. I knew my code wasn't efficient since I did most of the site before learning about functions and OOP, so it's procedural and very redundant. I will have to start updating it.

As for the IE issues, I'm still not exactly sure. I'll try some of your suggestions and then maybe make a virus that installs FF or chrome in place of IE whenever IE requests a page :P

Edit 2:

If anyone is wondering how this turned out - I've managed to decrease the loading time significantly by loading only what is initially visible and having ajax (via jQuery) load the data associated with each button slidedown on the event that each button is pressed. It's much faster now, and I still haven't omitted the several unneeded CSS files. It's still sluggish after load in IE8 but I'll tackle that another time and take your suggestions on that into consideration. Thanks for all your help!

我的网站上有一个框，当单击按钮时，框会向上滑动，将一些新文本加载到其中，然后向下滑动以显示新文本。这是我在 jQuery 中为它编写的代码：

问题是框​​一旦滑上去就会改变高度，因为新文本可能更短或更长。这意味着当盒子向下滑动时，一旦它到达盒子的“旧”高度，它就会猛拉到盒子的新高度。

这是 html 的示例，“lyric”中的所有内容都由“lyric.php”文件吐出：

和CSS：

我尝试过使用自定义动画，但我无法模仿 slideUp/Down 并解决盒子高度问题。任何帮助是极大的赞赏。

我在 wordpress 中做一个单页网站，我想在索引页面上只显示一篇文章以及文章的摘要。为此，我知道我可以在 loop.php 中将 the_content 更改为 the_excerpt。但是当我点击“继续阅读”时，我来到了一个新页面，这不是我想要的。我希望 div 向下滑动并在页面上显示整个新闻。

有没有办法做到这一点？

提前致谢

我有一个链接，当用户单击它时，一些数据会加载到div. 我想向用户显示等待消息，直到数据完全从服务器获取，然后将其显示给用户。

我还想调用数据url仅在结果框向下（向下滑动）时才发生，而不是在向下滑动和向上滑动事件中以减少服务器上的负载。

我的代码在这里，但我不知道如何实现第二部分：

你能帮我吗？？

我在切换下一个 div 时遇到问题。继承人的代码：

我的代码的jsfiddle

我需要做的是：单击下一步按钮后，它将关闭当前的box_content并按顺序打开下一个。简单，但我做不到......请帮忙。

我创建了一个站点，但是在 IE7 中出现了问题，我有一个导航，当我单击一个 li 元素时，所有 li 的上滑和匹配的 div 下滑。

这适用于除 IE7 以外的所有浏览器

有谁知道我需要做什么来解决这个问题？导致 min-width: 0 不起作用，我必须使用 position: relative

上滑有效，但下滑无效。

这就是我所拥有的...

为什么这个 jQuery 代码不起作用？

有人有什么想法吗？我不。

是否产生相同slideUp('slow')的hide('slow')动画效果？

示例代码：

我用 jQuery 编写了这段代码，以便有一个简单的悬停下拉菜单。它可以工作，但有时会非常跳动。当您将鼠标滑到某个位置或稍微快一点时，它会跳开/关闭并闪烁……不知道如何补救？

这是我当前的代码：
