PetitQ 其他代码 2019-3-01 2.38K 0 1

这是一款使用 GSAP 的 TweenMax.js 和 CSS3 来制作的效果炫酷的盒子爆炸动画特效。该爆炸动画在用户点击页面中的一个弹跳的盒子的时候，盒子会爆炸为烟雾，然后会出现 SVG Logo，整个效果非常连贯逼真。

HTML 结构

该盒子爆炸效果的 HTML 结构如下：div.-box 是一个立方体盒子，div.explode 用于制作爆炸的烟雾效果。svg.icon 则是最后出现的 SVG Logo。

CSS 样式

在 CSS 样式中，主要是制作盒子的立方体效果，以及使用 CSS3 帧动画来制作盒子的弹性和阴影动画效果。盒子的弹性和阴影动画效果。

盒子的立方体效果：由于 IE 浏览器不支持 transform-style: preserve-3d;属性，所以在 IE 浏览器中看不到盒子的立体效果。

JavaScript

该特性依赖于 GSAP 的 TweenMax.js，使用时需要将其引入。

<script src="js/jquery.min.js"></script>

<script src='http://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/TweenMax.min.js'></script>

该盒子爆炸动画特性的主要 JS 代码如下：

```
function init() {
```

  var emitter = document.getElementById("emitter"),

    container = document.createElement("div"),

```
    emitterSize = 100,
```
```
    dotQuantity = 50,
```
```
    dotSizeMax = 100,
```
```
    dotSizeMin = 10,
```
```
    speed = 1,
```
```
    gravity = 1;
```
```
 
```

  container.setAttribute("id", "emit-wrap");

  //setup the container with the appropriate styles

    container.style.cssText = "position:absolute; left:0; top:0; overflow:visible; z-index:5000; pointer-events:none;";

```
  document.body.appendChild(container);
```
```
 
```
```
  function createExplosion(container) {
```
```
    var tl = new TimelineLite({
```
```
      onComplete: function() {
```
```
        $('#emit-wrap').remove();
```
```
      }
```
```
    }),
```
```
      angle, length, dot, i, size;
```
```
    //create all the dots
```
```
    for (i = 0; i < dotQuantity; i++) {
```

      dot = document.createElement("div");

```
      dot.className = "emitter-dot";
```

      size = getRandom(dotSizeMin, dotSizeMax);

```
      container.appendChild(dot);
```

      angle = Math.random() * Math.PI * 2;

      length = Math.random() * (emitterSize / 2 - size / 2);

```
      TweenLite.set(dot, {
```
```
        x: Math.cos(angle) * length,
```
