摘要:本文要实现一个流程图的绘制,最终的目标是实现流程图的自动绘制,并可进行操作,直接点击流程图上对应的方框就可以让后台跑相应的程序。
1、图形绘制raphael
其中图形绘制使用了raphael,下载地址: http://raphaeljs.com,它的功能非常强大。
中文帮助教程: http://html5css3webapp.com/raphaelApi.htm#Paper.text
其中有一些DEMO如下:
2、鼠标右键菜单栏弹出smartMenu
教程及下载地址: 【jQuery】smartMenu右键自定义上下文菜单插件(似web QQ)
3、字体大小变化利器插件jquery.fontFlex
随着页面的放大或者缩小,字体也跟随着放大或者缩小。当然,可以设置一个最大值,一个中间值和一个最小值。此效果多半应用于响应式页面中,或者需要适用多版本终端浏览器的页面中
1、首先,来看看要实现的流程图的样子。
2、代码实现
这里其实就是把上面的插件都引用进来,然后其它的就是用JS不断画椭圆、直线箭头、方框等。
画好之后,添加文字,给方框添加右键点击事件
