制作svg动画
要实现一步一步画出来一个图片，css3做不到吧。除非一张张的图片定时显示。想不到别的招了。如今用的是一个插件，做了一个svg动画。
插件地址：http://lazylinepainter.info/
先用AI做好路径，保存为svg格式的文件。
使用插件。先引入须要的文件：
<script src=http://www.mamicode.com/"http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script>window.jQuery || document.write(‘<script src=http://www.mamicode.com/"jquery-1.9.1.min.js"></script>‘)</script>
<script src=http://www.mamicode.com/"jquery.lazylinepainter-1.5.1.js"></script>
demo例如以下：
