</html>所以，我有一个工作的JavaScript动画（使用GreenSock），你可以在这里看到http://codepen.io/jstafford/pen/VaLgvK。我试图将其插入到AngularJS指令中，但我甚至没有在安装程序（init-modal指令）或Next和Previous（step-modal指令）按钮的指令内进行。 1）按下Setup按钮，将三个圆和光标设置在触发init-modal指令的初始位置。2）然后按下Next按钮或Previoius按钮，触发step-modal指令，使step动画发生。我是AngularJS的新手，我正在尝试使用AngularJS的方式，但真的很挣扎。任何帮助不胜感激。
非常感谢！骆驼案件和限制“A”是我需要它的工作。我很感激。 –
