近期做项目用的是JQuery easyUI 控件， 尽管非常强大，可是高级控件对于数据的格式要求比較严格遇到 例如以下问题
1.使用comboTree 控件 绑定树形的组织结构 可是 数据库查到的数据格式是 列表形式，并不符合 combotree的数据结构 以下是我的数据和 combotree 数据个对照
通用的数据结构 命名A

以下是将A转化为B的javascript 代码
//rootParentIdValue 表示根节点的父类id 值是多少 如门店组织结构为-99
//parentIdName 表示父类id的节点名称是什么 如门店组织结构的名称 ParentUnitID
//nodeIdName 表示列表对象主键的名称 如门店是UnitID
// listData 为二维的树形结构列表
function listToTree(rootParentIdValue,parentIdName,nodeIdName,ListData){
if(ListData instanceof Array&&ListData.length>0&&ListData[i][parentIdName]){
//rootList 根节点集合 nodeList 子节点集合
var rootList=[], nodeList=[],allChildren=[];
// 分离出 根节点和子节点集合
$.each(ListData,function(index,node){
node.id=node[nodeIdName];node.text=node.UnitName;//id 和text为 必须设置由于我遇到的问题是combotree绑定数据显示乱码
if(node[parentIdName]==rootParentIdValue){
rootList.push(node);
}else{
nodeList.push(node);
}
});
//递归添加子节点 rootNodeList根节点集合。 //子节点集合 闭包结构
function childrenNodeAdd(rootNodeList,childrenList){
//debugger;
if(childrenList.length>0){ // 假设没有子节点了结束递归
//遍历根节点集合在 子节点中查找其自身的子节点并加入根节点相应的子节点
$.each(rootNodeList,function(index,rootNode){ //遍历全部子节点
rootNodeList[index]["children"]=[];
$.each(childrenList,function(childrenIndex,childrenNode){
if(parentIdName in childrenNode&&rootNode[nodeIdName]==childrenNode[parentIdName]){ //跟节点的id 等于子节点的父类id
rootNodeList[index]["children"].push(childrenNode); //加入相应节点归为子节点
allChildren.push(node);// 缓存全部已经加入过的对象
}
});
var childrenNodeList=[] //一级节点加入完以后看是否还有剩余的子节点
//筛选器剩余的子节点
$.each(childrenList,function(childrenIndex,childrenNode) {
var isAdd=true
$.each(allChildren,function(index,node) {
if(node==childrenNode){
isAdd=false
}
});
if(isAdd){
childrenNodeList.push(childrenNode);
}
});
childrenNodeAdd(rootNodeList[index]["children"],childrenNodeList);//剩余子节点继续递归运行 每次递归一次就表示节点添加一级。
})
}
}
debugger;
if(nodeList.length>0&&rootList.length>0){
childrenNodeAdd(rootList,nodeList);
return {isTree:false,Data:rootList,message:"转化完毕"}
}else if(rootList.length>0){
return {isTree:false,Data:ListData,message:"没有相应的子节点集合"}

树形转化为列表的代码有兴趣的人能够开发一下。

注意combotree 绑定数据中文easy产生undefined 解决方式就是将 我们查询出来的id字段名称 用id 取代。显示的文字用text 我的代码就是 id取代了UnitID text取代了UnitName 详细原因限制未知。 英文无此类问题。
