TweenMax—ScrambleText插件实现类似电脑破译密…

首先贴一下TweenMax的中文网：https://www.tweenmax.com.cn/

首先先展示一下最后的效果，需要的就继续看下去：

那团乱码是会一直变的

那么如何实现上图的效果呢？？？

其实就是运用了TweenMax的插件ScrambleTextPlugin（在这个页面可以下载：https://www.tweenmax.com.cn/source/）

代码如下：

$(document).ready(function(){
    var tl = new TimelineLite();
    tl.to("#scramble1",3,{delay:2})//这边的delay就是用来做延迟显示的，也可以去掉的。用scrambleText这个插件的意义其实就是：当第一个动画结束之后，第二个动画才会开始，所以应该是去避免使用delay属性的
      .to("#scramble1",8,{scrambleText:{text:"{original}", chars:"upperAndLowerCase", revealDelay:0.5, tweenLength:true, newClass:"class2", oldClass:"class1",speed:10,delimiter:""}, ease:Linear.easeNone})
      .to("#scramble2",3,{delay:2}) 
      .to("#scramble2",8,{scrambleText:{text:"{original}", chars:"upperAndLowerCase", revealDelay:0.5, tweenLength:true, newClass:"class2", oldClass:"class1",speed:10,delimiter:""}, ease:Linear.easeNone})
      .to("#scramble3",3,{delay:2})
      .to("#scramble3",8,{scrambleText:{text:"{original}", chars:"upperAndLowerCase", revealDelay:0.5, tweenLength:true, newClass:"class2", oldClass:"class1",speed:10,delimiter:""}, ease:Linear.easeNone})
      .to("#scramble4",3,{delay:2})
      .to("#scramble4",8,{scrambleText:{text:"{original}", chars:"upperAndLowerCase", revealDelay:0.5, tweenLength:true, newClass:"class2", oldClass:"class1",speed:10,delimiter:""}, ease:Linear.easeNone});
})

相应的参数如下图所示：
