基于GOJS绘制流程图

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：

工具库依赖于go.js、jquery以及layer.js

流程设计器操作指南:

1. 在任意位置双击设计器空白处：新建步骤；
2. 选中步骤，单击右键：弹出右键菜单；
3. 鼠标滑过步骤，显示连接点，拖动连接点即可创建新的连接线；
4. 鼠标滑过步骤：显示tooltip。

##流程图数据

{ "class": "go.GraphLinksModel",
  "modelData": {"position":"-5 -5"},
  "nodeDataArray": [
{"key":"", "text":"开始", "figure":"Circle", "fill":"#4fba4f", "stepType":, "loc":"90 110"},
{"key":"", "text":"结束", "figure":"Circle", "fill":"#CE0620", "stepType":, "loc":"770 110"},
{"key":"", "text":"填写请假信息 ",  "loc":"210 110", "remark":""},
{"key":"", "text":"部门经理审核 ",  "loc":"370 110", "remark":""},

 ],
  "linkDataArray": [

1.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

2.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';// 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
