此代码接着JS流程设计器(一)续写,该代码主要是怎么将设计好的流程图用最基本字符串的方式传到后台,再由后台字符串的方式重新显示在页面上。

 1 //转化成后端的方法
 2     function changebe(firstbegin){
 3         for(var x=0;x<shapeobjjson.shapeobj.length;x++){
 4             if(shapeobjjson.shapeobj[x].id==firstbegin){
 5                 if(firstbegin.indexOf("begin-circle")>-1){
 6                     laststr=laststr+"begin("+$("#"+firstbegin).text()+")";
 7                 }else if(firstbegin.indexOf("tableform")>-1){
 8                     laststr=laststr+"tab("+$("#"+firstbegin).text()+")";
 9                 }else if(firstbegin.indexOf("approval-circle")>-1){
10                     laststr=laststr+"dug("+$("#"+firstbegin).text()+")";
11                 }else if(firstbegin.indexOf("end-circle")>-1){
12                     laststr=laststr+"end("+$("#"+firstbegin).text()+")";
13                 }
14                 for(var y=0;y<lineobjjson.lineobj.length;y++){
15                     if(firstbegin==lineobjjson.lineobj[y].startid){
16                         laststr=laststr+">";
17                         changebe(lineobjjson.lineobj[y].endid);
18                     }
19                 }
20             }
21         }
22     }

显示的主要字符串的样式为:"begin(开始)>tab(表单1)>dug(审批2)>tab(表单2)>dug(审批1)>dug(审批4)>tab(表单3)>dug(审批5)>dug(审批6)>tab(表单4)>dug(审批7)>dug(审批8)>dug(审批9)>end(结束1)";

从后端传入前端并显示在前台的代码如下:

  1 //定义每一行对象的宽度总和是多少
  2     var objsumwidth=0;
  3     //前一个对象的宽度和高度
  4     var beforewidth=0;
  5     var beforeheight=0;
  6     //*******************************将后台传过来的字符串转化为前台图形********************************//
  7     //假设后台传过来的字符串是开始,begin-circle>表单1,tableform>审批2,approval-circle>表单2,tableform>审批1,approval-circle>结束,end-circle
  8     var firststr="begin(开始)>tab(表单1)>dug(审批2)>tab(表单2)>dug(审批1)>dug(审批4)>tab(表单3)>dug(审批5)>dug(审批6)>tab(表单4)>dug(审批7)>dug(审批8)>dug(审批9)>end(结束1)";
  9     changefe(firststr);
 10     //转化成前端的方法
 11     function changefe(firststr){
 12         for(var a=0;a<firststr.split(">").length;a++){
 13             whichobj(firststr.split(">")[a].split("(")[0]);
 14             if(a%5==4){
 15                 var avgwidth=(parseFloat($("#right-area").width())-objsumwidth)/5.0;
 16                 //判断方向是从左往右还是从右往左的方向
 17                 if(a%10==4){//从左往右画对象
 18                     for(var b=a-4;b<=a;b++){
 19                         if(b==a-4){
