第归方法创建树形图
1)TreeGraph.js文件内容如下:
function treeMenu(a){
//列表map形式
this.tree=a||[];
this.groups={};
//存放id与对应的name映射
this.nameMap={}
//得到每个点对应的层次,为了后期进行布局
this.levelMap={}
//样式设计
this.style={"symbolSize":[60,50,40,30,20],"value":[8,6,4,2,1]}
};
treeMenu.prototype={
init:function(pid){
this.group();
this.MapNamebyId();
this.setIdLevel(pid);
return this.rescusive(pid);
},
group:function(){
for(var i=0;i<this.tree.length;i++){
//存在该grops则直接添加
if(this.groups[this.tree[i].pId]){
this.groups[this.tree[i].pId].push(this.tree[i]);
}else{
this.groups[this.tree[i].pId]=[];
this.groups[this.tree[i].pId].push(this.tree[i]);
}
}
},
//得到每个点的层次
setIdLevel:function(pid){
var level=1;
this.levelMap[pid]=level;
var gs=this.groups[pid];
//str=JSON.stringify(gs)
//alert("json:"+str)
var temp=[]
while(gs){
level++;
if(gs==null||gs==undefined||gs.length==0)
break;
temp=[]
for(var i=0;i<gs.length;i++){
var myid=gs[i]["id"];
this.levelMap[myid]=level;
subgs=this.groups[myid];
if(subgs instanceof Array &&subgs!=null){
for(var j=0;j<subgs.length;j++){
temp.push(subgs[j]);
}
}
}
gs=temp;
}
},
//根据所在层次设计不同大小的样式
getStyleById:function(id){
var level=this.levelMap[id]
if(level>=5)
level=5;
var symbolize=0
var value=0
symbolize=this.style['symbolSize'][level-1]
value=this.style['value'][level-1]
var styleValue={}
styleValue['symbolSize']=symbolize
styleValue['value']=value
return styleValue
},
MapNamebyId:function(){
for(var i=0;i<this.tree.length;i++){
map=this.tree[i]
this.nameMap[map["id"]]=map["name"]
}
},
//设置节点属性
setNode:function(node,name,symbolize,value,children){
node['name']=name;
node['symbolSize']=symbolize;
node['value']=value
node['children']=children
return node;
},
rescusive:function (number){//这里是构建数据源的重点
var data=[]
var node={}
var styleValue={}
//某个节点下的子节点
var a=this.groups[number];
var nodeName=this.nameMap[number];
if(a==null||a==undefined){
styleValue=this.getStyleById(number)
//设置节点
this.setNode(node,nodeName,styleValue['symbolSize'],styleValue['value'],[])
return node;
}
for(var i=0;i<a.length;i++){
children=this.rescusive(a[i].id);
data.push(children);
}
styleValue=this.getStyleById(number)
this.setNode(node,nodeName,styleValue['symbolSize'],styleValue['value'],data)
return node;
},
//创建组织结构图
createTreeVisual:function(myChart,title,data){
var option = {
title : {
text: title
},
tooltip : {
trigger: 'item',
formatter: "{b}"
},
toolbox: {
show : true,
feature : {
saveAsImage : {show: true}
}
},
calculable : false,
series : [
{
name:'树图',
type:'tree',
orient: 'horizontal', // vertical horizontal
rootLocation: {x: 100, y: '60%'}, // 根节点位置 {x: 'center',y: 10}
nodePadding: 20,
symbol: 'circle',
data:data
}]//series
}
myChart.setOption(option);
}
}
//得到数据
function getData(zNodes){
var mytree=new treeMenu(zNodes)
treeData=mytree.init(0)
data=[]
data.push(treeData)
return data;
//str=JSON.stringify(menu);
//alert("responsing json:"+str)
}
function createTreeV(mychart,title,znodes){
var mytree=new treeMenu(znodes)
treeData=mytree.init(1)
data=[]
data.push(treeData)
mytree.createTreeVisual(myChart,title,data)
}
