我想实现这样的例子:http://cn.vuejs.org/examples/...
它是用vue实现的,用ko的怎么做到?
我的数据结构类似这样(层级不确定):

var data=[
                {
                    id:1,
                    "text": "111-1",
                    "children": []
                }, 
                {
                    id:2,
                    "text": "111-2",
                    "children": [
                    {
                        id:2-1,
                        "text": "111-2-1",
                        "children": [
                            {
                                id:2-1-1,
                                "text": "111-2-1-1",
                                "children": [
                                    {
                                        id:2-1-1-1,
                                        "text": "111-2-1-1-1",
                                        "children": []
                                    }
                                ]
                            },
                            {
                                id:2-1-2,
                                "text": "111-2-1-2",
                                "children": []
                            }
                        ]
                    }, 
                    {
                        id:2-2,
                        "text": "111-2-2",
                        "children": []
                    },                     
                    {
                        id:2-3,
                        "text": "111-2-3",
                        "children": []
                    }
                    ]
                }
            ]

请大神们指教。

父组件中

<items  :model='model' v-for='model in data'></items>

子组件 记住vue中递归组件给name属性 按照name递归循环

<template>
    <li >
        <p @click='toggle'>
            {{model.id}}<span v-if='isFolder'>[{{open?"-":"+"}}]</span>
        </p>
        <ul v-show="open" v-if='isFolder'>
            <items v-for='cel in model.children' :model='cel' ></items>
        </ul>
    </li>
</template>
<script type="text/javascript">
    export default{
        name:'items',
        props:['model'],
        components: {
        },
        data(){
            return{
                open:false,
                isFolder:true
            }
        },
        computed: {
           isFolder:function(){
                return this.model.children && this.model.children.length
            }
        },
        methods:{
            toggle:function(){
                if(this.isFolder){
                    this.open=!this.open
                }
            },
        }
    }
</script>
