1.1根据勾选的最底层 子节点 ，获取权限树 数据
getPriTreeDataBySelectedPriIdList(treeData, priIdList){
//根据最底层子节点，获取权限树数据
return treeData.filter(item=>{
if(item.childs && item.childs.length > 0 ){
item.childs = this.getPriTreeDataBySelectedPriIdList(item.childs,priIdList);
return item.childs && item.childs.length >0;
}else {
return priIdList.indexOf(item.id) > -1;
}
});
},
1.2重置权限树数据
resetTreeData(priTreeData){
//重置权限树数据
priTreeData.map(item => {
item.isInherit = false;
if(item.childs && item.childs.length>0){
this.resetTreeData(item.childs);
}
})
},
1.3根据任意ID获取item对象
getItemFromPriTreeData(priTreeData, priId){
//根据任意ID获取item对象
let result = null;
for(let priItemIndex in priTreeData){
if(result !== null){
break;//这里是关键
}
let priItem = priTreeData[priItemIndex];
if(priItem.id === priId){
result = priItem;
break;
}else if(priItem.childs && priItem.childs.length > 0){
result = this.getItemFromPriTreeData(priItem.childs, priId);
}
}
return result;
},
1.4父节点勾选了，勾选所有的子节点
setIsInheritValueWithParentPri(priList, isInherit){
// 递归的设置"是否继承属性"
// 父节点勾选是否继承，子节点跟随父节点变化 子节点变化，父节点不跟随变化
priList.map(priItem => {
if(priItem.type !== 3){
priItem.isInherit = isInherit;
}
if(priItem.childs && priItem.childs.length > 0){
this.setIsInheritValueWithParentPri(priItem.childs, isInherit);
}
})
},
1.5设置详情页中---展示树数据中的isInherit
setInheritOfShowPriTreeData(showPriTreeData, priTreeDataPriIdAndHeritObject){
// 设置详情页中---展示树数据中的isInherit
showPriTreeData.map(priItem => {
priItem.isInherit = priTreeDataPriIdAndHeritObject[priItem.id];
if(priItem.childs && priItem.childs.length > 0){
this.setInheritOfShowPriTreeData(priItem.childs, priTreeDataPriIdAndHeritObject )
}
})
},
1.6设置选中的权限树数据相关信息到priTreeDataPriIdAndHeritObject，priIdListIncludeParentPriId中
setPriTreeDataPriIdAndHeritObject(priTreeDataBySelectedPriIdList, priTreeDataPriIdAndHeritObject,priIdListIncludeParentPriId){
// 设置选中的权限树数据相关信息到priTreeDataPriIdAndHeritObject，priIdListIncludeParentPriId中
//priTreeDataPriIdAndHeritObject是对象，key是权限ID，value是isInherit
//priIdListIncludeParentPriId 根据最底层子节点获得的权限树数据，把所有的权限ID都放到列表中
priTreeDataBySelectedPriIdList.map(priItem => {
priIdListIncludeParentPriId.push( priItem.id);
if(priItem.isInherit){
priTreeDataPriIdAndHeritObject[ipriItem.id] = priItem.isInherit;
}else{
priTreeDataPriIdAndHeritObject[priItem.id] = false;
}
if(priItem.childs && priItem.childs.length>0){
this.setPriTreeDataPriIdAndHeritObject(priItem.childs, priTreeDataPriIdAndHeritObject,priIdListIncludeParentPriId)
}
})
}
