先上个效果图。
以上效果为自己拖拽画布效果，可在每一个任务节点上去配置对应的name,function.
具体代码。
1.js,css引用
2。HTML JS

3.如何将流程图拆散后保存入库。
private void AddFlow(HttpContext context)
{
string data = context.Request.Form["data"];
string moduleid = context.Request.Form["moduleid"];
string Eid = context.Request.Form["Eid"];
DataTable dts=new DataTable();
dts = SDA.GetModuleFunction(moduleid);
string functionNmae = "";
if (dts.Rows.Count>0)
{
functionNmae = dts.Rows[0][0].ToString();
}
//DataTable dt = new DataTable();
string strtempa = "type:'start'";//判断流程图是否选择了开始
string strtempb = "type:'end'";//判断流程图是否选择了结束
string strtempc = "type:'task";//判断流程图是否选择的了任务
int IndexofA = data.IndexOf(strtempa);
int IndexofB = data.IndexOf(strtempb);
int IndexofC = data.IndexOf(strtempc);
int error = 0;
if (IndexofA == -1)
{
error++;
}
if (IndexofB == -1)
{
error++;
}
if (IndexofC == -1)
{
error++;
}
if (error>0)
{
context.Response.Write("error");
}
else
{
List<string> ls = new List<string>();
ls=pb.DoDebug(data);
string strtempD = "temp3:";
string Flowname = "Flowname";
string FlowN = "";
ls.RemoveAt(ls.Count - 1);
ls.RemoveAt(ls.Count - 2);
for (int i = ls.Count - 1; i >= 0; i--)
{
if (ls[i].IndexOf(Flowname) == 0)
{

}
if (ls[i].IndexOf(strtempD) !=0)

foreach (var i in strarr)
{
if (i.ToString() != "")
{
lss.Add(i);
}
}
flow_Flow ff = new flow_Flow();
if (lss.Count==1)
{
ff.FlowName = lss[0];
}
else if (lss.Count > 1)
{
ff.FlowName = lss[0];
ff.FlowDesc = lss[1];
}
ff.ModuleID = moduleid;
ff.CreateEmployeeID = Eid;

flow_FlowText fft = new flow_FlowText();

flow_FlowInfo fi = new flow_FlowInfo();
List<flow_FlowInfo> lfi=new List<flow_FlowInfo>();
for (int i = 0; i < ls.Count; i++)
{
string fitemp = ls[i].Replace("temp3:{value:", "").Replace("},temp2:{value:", ",").Replace("}", "");
string[] temparr = fitemp.Replace("'", "").Split(',');
if (temparr.Length>0)
{
fi = new flow_FlowInfo();
fi.Text = temparr[0];
fi.FunctionID = temparr[1];
if (fi.FunctionID=="")
{
fi.FunctionID = functionNmae;
}
fi.ISJH = 0;
lfi.Add(fi);
}
}
if (da.InsertFlow(ff, lfi, fft))
{
context.Response.Write("OK");
}
else
{
context.Response.Write("waring");
}
}
}
public List<string> DoDebug(string data)
{
List<string> oGet = new List<string>();
string sPut = data;
Stack<StringBuilder> stack = new Stack<StringBuilder>();
stack.Push(new StringBuilder(""));
foreach (var cPut in sPut)
{
switch (cPut)
{
case '{':
stack.Peek().Append(cPut);
stack.Push(new StringBuilder(""));
break;
case '}':
StringBuilder oPop = stack.Pop();
oGet.Add(oPop.ToString());
stack.Peek().Append(oPop.ToString());
stack.Peek().Append(cPut);
break;
default:
stack.Peek().Append(cPut);
break;
}
}
while (stack.Count > 0)
{
StringBuilder oPop = stack.Pop();
oGet.Add(oPop.ToString());
}
return oGet;
}
要点：当我们将要保存的value取去来时，会发现这是一个稍微比较复杂的json串，或者说是一个不是贴别规范的json串比较合适。
我将任务开始节点的名称取关键字段temp3，temp2,保证生成数据时，能够有唯一条件供我筛选。
下面是将保存在数据库的数据，在显示的截图。
在查看页面就是一个很简单的数据输出，并且不显示其他的图列，属性等信息。
有需要的同学，可以私聊我，给你们源码demo。有好多功能正在研究中，希望大家能够衍生出更好，更实际的功能。
