jquery - React-select-plus 选项组下拉异步问题

Question

我正在使用 React-Select Plus 控件来绑定 React 中的下拉菜单。我在 React 中绑定异步选项组下拉时发现问题。这是我的代码：

  getSearch = (input) => {
    if (!input) {
      return Promise.resolve({ options: [] });
    }
    const newstate = this.state;
    this.setState({ newstate });

    newstate.loadingtext = 'Searching...';
    const searchLocation = Object.assign({}, cookie.load('cLocation'));
    searchLocation.searchText = input;
    searchLocation.isBusiness = true;
    const myInit = {
      method: 'POST',
      headers: {
        'Access-Control-Allow-Origin': '*',
        'Content-Type': 'application/json',
        Accept: 'application/json',
      },
      body: JSON.stringify(searchLocation),
    };
    return fetch(`url/methodname`, myInit)
    .then(response => response.json())
    .then(json => [{ value: json.data, label: json.data }]);
  }
    gotoSearch = (value) => {
    window.open(value.html_url);
  }

<Select.Async
              onChange={this.onChange}
              onValueClick={this.gotoSearch}
              valueKey="placeID"
              labelKey="cityState"
              loadOptions={this.getSearch}
              value={this.state.value}
              loadingPlaceholder={this.state.loadingtext}
              noResultsText="No results found"
              placeholder="Name, City, Zip"
              options={ops}
            />
