javascript - 网站上的动画故障

标签 javascript html css animation

我做了一个小规模的实验，我在下面的 jsfiddle 中测试当你反复点击黄色方 block 时会发生的动画:

http://jsfiddle.net/aritro33/v86tE/5/

但是，当您点击撰写/发布圆圈/按钮时，我试图将在该 jsfiddle 中看到的动画移动到此处的 jsfiddle。动画将应用于帖子。这是 jsfiddle:

但是我遇到了问题，在点击撰写和发布按钮 3 次以上后，动画崩溃了。

关于如何将在第一个 jsfiddle 中看到的相同动画放入帖子的第二个 jsfiddle 中有什么想法吗？

非常感谢任何可以提供帮助的人!

第二个实验的 HTML:

<div id="compose"><span id="firstspan">Compose</span>
 <span id="fourthspan">Post</span>

</div>
<span id="noposts">- No Posts Yet -</span>

<div id="composeheader">
    <input type="text" id="secondspan" value="Write Header Here:" />
</div>
<div id="thecolor"></div>
<div class="bubble">
    <input type="text" id="thehex" value="#2AC0A3" />
</div>
<div id="body"><span id="thirdspan" contenteditable="true">Write context text here:</span>

</div>
<ul id="allposts"></ul>

最佳答案

我已经清理了很多，现在代码应该更容易阅读和理解了:

HTML

<script id="empty-message" type="html/template">
    <div class="message new box animated bounceInDown">
        <div class="thecolor"></div>
        <div class="bubble">
            <input type="text" class="hexcolor" value="#2AC0A3" />
        </div>
        <div class="composeheader">
            <input type="text" value="Write Header Here:" />
        </div>
        <div class="body">
            <span contenteditable="true">Write context text here:</span>

jsFiddle Demo

为您的 id 和 css 类使用有意义的名称，它使代码更容易理解和理解正在发生的事情。 “firstspan”等样式没有任何意义，意味着您必须不断回顾标记以找出上下文。

我已经尽我所能清理了它，我不擅长 CSS3 或动画的东西，我会留给你来解决它。我认为这应该是现在完全按照您的预期工作，消息向下滑动并自上而下添加到堆栈中。

编辑 2: 我更改了许多要使用的 ID 选择器，并重构了代码以使其更简单。您还在新创建的元素上设置了相同的 ID，这是错误的，并且会导致您进一步出现问题(每页的 ID 应该是唯一的)。 我清理了 JS，合并了多个语句，这些语句对不同的选择器执行相同的操作。您使用了很多标准的 JavaScript getElementById 类型调用，我更改了这些调用，改为使用 jQuery 创建 DOM 元素。

我使用 html/template 脚本声明来创建新元素，它比使用 jQuery 构建新的 DOM 元素要干净得多。此外，您的 compose 和 post 元素本质上是同一件事。不要重复 CSS 样式，要么组合多个选择器，要么像我一样重复使用相同的结构。希望这些更改有意义。
