javascript - 冲压发动机 : How to make element appear and reappear

转载作者：太空宇宙更新时间：2023-11-04 03:07:57

所以我正在尝试遵循冲压喷气发动机的代码 http://www.rich-harris.co.uk/ramjet/ ，但我无法让元素 a 在移动到 b 时消失。我还得到 --Uncaught TypeError: Cannot read property 'add' of undefined--。不过，元素 a 确实会移动。如何让 a 变成 b，如页面所示。

脚本.js

$(document).ready( function() {
// set the stage so ramjet copies the right styles...
b.classList.remove('hidden');

ramjet.transform( a, b, {
  done: function () {
    // this function is called as soon as the transition completes
    b.classList.remove('hidden');
  }
});

// ...then hide the original elements for the duration of the transition
a.classList.add('hidden');
b.classList.add('hidden');
});

index.html

<!DOCTYPE HTML>
<html>
<head>
    <link type="text/css" rel="stylesheet" href="stylesheet.css" />
    <script src="http://code.jquery.com/jquery.min.js"></script>
    <script type="text/javascript" src="./ramjet.js"></script>
    <script type="text/javascript" src="./script.js"></script>

</head>

<body>
    <div class="back">
       <div id="a"></div>
       <div id="b" class="hidden"></div>
    </div>
</body>
</html>

样式表.css

.back {
    float: left;
    width: 790px;
    height: 525px;    
    border-radius: 5px;
    background-color: #BCD2EE
}

#a {
    margin: 200px 10px;
    margin-right: auto;
    width: 175px;
    height: 60px;
    background-color: #666699;
    display: inline-block;
    position: relative;
    border: 2px solid black;
}

#b {
    margin: 200px 10px;
    margin-right: auto;
    width: 175px;
    height: 60px;
    background-color: red;
    display: inline-block;
    position: relative;
    border: 2px solid black;
}

.hidden {
    visibility: hidden;
}

最佳答案

这是我的 head 标签中的脚本:

<script type="text/javascript" src="jquery-1.11.1.js"></script>
<script type="text/javascript" src="ramjet.js"></script>
<script type="text/javascript">
$(document).ready( function() {
// set the stage so ramjet copies the right styles...
b.classList.remove('hidden');

ramjet.transform( a, b, {
  done: function () {
    // this function is called as soon as the transition completes
    b.classList.remove('hidden');
  }
});

// ...then hide the original elements for the duration of the transition
a.classList.add('hidden');
b.classList.add('hidden');
});
</script>
