json数组根据id和父id排序

Question

var zNodes =[
{ id:1, pId:1, name:"父节点1", open:true},
{ id:11, pId:1, name:"父节点11"},
{ id:111, pId:11, name:"叶子节点111"},
{ id:112, pId:11, name:"叶子节点112"},
{ id:113, pId:11, name:"叶子节点113"},
{ id:114, pId:11, name:"叶子节点114"},
{ id:12, pId:1, name:"父节点12"},
{ id:121, pId:12, name:"叶子节点121"},
{ id:122, pId:12, name:"叶子节点122"},
{ id:123, pId:12, name:"叶子节点123"},
{ id:124, pId:12, name:"叶子节点124"},
{ id:13, pId:1, name:"父节点13", isParent:true},
{ id:2, pId:0, name:"父节点2"},
{ id:21, pId:2, name:"父节点21", open:true},
{ id:211, pId:21, name:"叶子节点211"},
{ id:212, pId:21, name:"叶子节点212"},
{ id:213, pId:21, name:"叶子节点213"},
{ id:214, pId:21, name:"叶子节点214"},
{ id:22, pId:2, name:"父节点22"},
{ id:221, pId:22, name:"叶子节点221"},
{ id:222, pId:22, name:"叶子节点222"},
{ id:223, pId:22, name:"叶子节点223"},
{ id:224, pId:22, name:"叶子节点224"},
{ id:23, pId:2, name:"父节点23"},
{ id:231, pId:23, name:"叶子节点231"},
{ id:232, pId:23, name:"叶子节点232"},
{ id:233, pId:23, name:"叶子节点233"},
{ id:234, pId:23, name:"叶子节点234"},
{ id:3, pId:0, name:"父节点3", isParent:true}
];

这是需要的效果，子类跟在他的父类后面，但现在json数组顺序不确定，求大神拯救

Answer 1

json数组

rray.sort(getSortFun('desc', 'phone'));
function getSortFun(order, sortBy) {
var ordAlpah = (order == 'asc') ? '>' : '<';
var sortFun = new Function('a', 'b', 'return a.' + sortBy + ordAlpah + 'b.' + sortBy + '?1:-1');
return sortFun;
}

alert(JSON.stringify(array));
数组本身有sort方法，可以指定排序函数，因此可以动态生成一个排序函数来完成对按指定对象属性排序的需求；

注意：sort后原数组序列会发生变化！！
