一些封装方法

handleAllChecked

• 解决el-tree全选后, 新增的节点默认有选中效果的bug

let dataSource = [
    {
        name: "test1",
        id: "test1",
        codes: "test1",
        children: [
            {
                name: "test2",
                id: "test2",
                codes: "test2"
            },
            {
                name: "test3",
                id: "test3",
                codes: "test3"
            },
            {
                name: "test4",
                id: "test4",
                codes: "test4"
            }
        ]
    }
];
