observer-dep-watch's Issues

watch b.c不生效

watch

class Watch {
    constructor (exp, fn) {
        this.exp = exp
        this.fn = fn
        pushTarget(this)
        data[exp]
    }
}

当访问多嵌套的对象是data[exp]有问题，比如new Watch('b.c', () => {})
下面可行？

class Watch {
    constructor (exp, fn) {
        this.exp = exp
        this.fn = fn
        pushTarget(this)
        var arr = exp.split('.')
        var obj = data
        for (var e of arr) {
            obj = obj[e]
        }
    }
}
