我有一个div，其中附加了另外三个div，如下所示。状态值是通过循环componentWillReceiveProps()的API的结果来设置的。但是我遇到了一个错误问题
Uncaught NotFoundError: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node
并且如果API结果为空则获取
Uncaught DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.
我该怎么补救呢？

componentWillReceiveProps(nextProps) {
    var sub1 = [], sub2 = [], sub3 = [];
    if(result) {
        result.sub1.map((item, index) => {
            sub1.push(
                <div>
                    <p>{item.name}</p>
                </div>
            )
        })
        result.sub2.map((item, index) => {
            sub2.push(
                <div>
                    <p>{item.name}</p>
                </div>
            )
        })
        result.sub3.map((item, index) => {
            sub3.push(
                <div>
                    <p>{item.name}</p>
                </div>
            )
        })

        this.setState({ subDiv1:sub1, subDiv2:sub2, subDiv3:sub3 })
    }
}

render() {
    return(
        <div className="row top_bar">
            <div className="search left col-xs-5 col-sm-4 col-md-5 col-lg-6">
                <form>
                    <input type="text" id="search_box" name="search_box" placeholder="Search" onKeyUp={this.keyUpFn} />
                </form>
                <div className="div1">
                    { this.state.subDiv1 }
                    { this.state.subDiv2 }
                    { this.state.subDiv3 }
                </div>
            </div>
            <div className="top_right col-xs-7 col-sm-8 col-md-7 col-lg-6">
                <div className="top_outer">
                </div>
            </div>
        </div>
    )
}
