js工作流组件很多，但是要找一款适合自己的却有点难，所以，咬咬牙，决定自己做一款。本着“不重复造轮子”的原则，我打算还是基于gojs封装流程图组件比较现实一点。先给大家看一下俺的成果：

在线Demo http://demo.e5j.net/flowdiagram/site/samples/_demo.html

希望支持FlowDiagram的童鞋能够到Github给我们一个star https://github.com/mengmakies/FlowDiagram

基于GOJS封装的流程图设计（展示）工具类，主要分为两个工具类（FlowDesigner和FlowDisplay）。

"modelData": {"position":"-5 -5"}, "nodeDataArray": [ {"key":"1", "text":"开始", "figure":"Circle", "fill":"#4fba4f", "stepType":1, "loc":"90 110"}, {"key":"2", "text":"结束", "figure":"Circle", "fill":"#CE0620", "stepType":4, "loc":"770 110"}, {"key":"3", "text":"填写请假信息 ", "loc":"210 110", "remark":""}, {"key":"4", "text":"部门经理审核 ", "loc":"370 110", "remark":""}, {"key":"5", "text":"人事审核 ", "loc":"640 110", "remark":""}, {"key":"6", "text":"副总经理审核 ", "loc":"510 40", "remark":""}, {"key":"7", "text":"总经理审核 ", "loc":"500 180", "remark":""} ], "linkDataArray": [ {"from":"1", "to":"3"}, {"from":"3", "to":"4"}, {"from":"4", "to":"5"}, {"from":"5", "to":"2"}, {"from":"4", "to":"6", "key":"1001", "text":"小于5天 ", "remark":"", "condition":"Days<5"}, {"from":"6", "to":"5"}, {"from":"4", "to":"7", "key":"1002", "text":"大于5天 ", "remark":"", "condition":"Days>5"}, {"from":"7", "to":"5"}

1. 引入js库文件

<script src="http://libs.baidu.com/jquery/1.9.1/jquery.min.js"></script>
<script src="js/layer/layer.js"></script><!--弹出框、提示tip-->
<script src="go.js"></script>
<script src="js/flow-desinger.js"></script><!--流程图设计器-->
<script src="js/flow-display.js"></script><!--流程图展示-->
2. 流程图设计 flow-desinger.js
    var areaFlow = document.getElementById('mySavedModel');
    var  myDesigner= new FlowDesigner('myFlowDesignerDiv');// 流程图设计器
    myDesigner.initToolbar('myPaletteDiv');// 初始化控件面板
    myDesigner.displayFlow(areaFlow.value);// 在设计面板中显示流程图
3.流程图展示 flow-display.js
    var areaFlow = document.getElementById('mySavedModel');
    var myDisplay = new FlowDisplay('myDisplayDiv');// 流程图显示器
    var flowPath = '3,4,6,5';// 流程路径。3,4,6,5是步骤的id，最后一个步骤为"待处理"或"已完成"的步骤
    var isCompleted = false;// "待处理"或"已结束"
    myDisplay.loadFlow(areaFlow.value);// 显示流程图
    myDisplay.animateFlowPath(flowPath, isCompleted);// 动画显示流程路径
