原数据

		data:[
			{id: 1, name: '张三', text: '呵呵'},
         	{id: 2, name: '张三', text: '无聊'},
            {id: 3, name: '张三', text: '玩玩'},
            {id: 4, name: '李四', text: '啊啊'},
            {id: 5, name: '王五', text: '偷偷'},
            {id: 6, name: '赵六', text: '试试'}
           ]

我们现在需要根据name这个属性拆分分类，同一类的要放在一个数组里面，代码。

data.forEach(item => {
       const parent = dataarr.find(c => c.name === item.name)
      if (parent) {
            parent.childs.push(item)
      } else {
           const obj = {
                         name: item.name,
                         childs: [item]
                       }
        dataarr.push(obj)
     }
})

分类后结果得到

[
    {
        "name": "张三",
        "childs": [
            {
                "id": 1,
                "name": "张三",
                "text": "呵呵"
            },
            {
                "id": 2,
                "name": "张三",
                "text": "无聊"
            },
            {
                "id": 3,
                "name": "张三",
                "text": "玩玩"
            }
        ]
    },
    {
        "name": "李四",
        "childs": [
            {
                "id": 4,
                "name": "李四",
                "text": "啊啊"
            }
        ]
    },
    {
        "name": "王五",
        "childs": [
            {
                "id": 5,
                "name": "王五",
                "text": "偷偷"
            }
        ]
    },
    {
        "name": "赵六",
        "childs": [
            {
                "id": 6,
                "name": "赵六",
                "text": "试试"
            }
        ]
    }
