import { Icon, Button, Input, AutoComplete } from 'antd';
const Option = AutoComplete.Option;

function onSelect(value) {
  console.log('onSelect', value);
}

function getRandomInt(max, min = 0) {
  return Math.floor(Math.random() * (max - min + 1)) + min; // eslint-disable-line no-mixed-operators
}

function searchResult(query) {
  return (new Array(getRandomInt(5))).join('.').split('.')
    .map((item, idx) => ({
      query,
      category: `${query}${idx}`,
      count: getRandomInt(200, 100),
    }));
}

function renderOption(item) {
  return (
    <Option key={item.category} text={item.category}>
      {item.query} 在
      <a
        href={`https://s.taobao.com/search?q=${item.query}`}
        target="_blank"
        rel="noopener noreferrer"
      >
        {item.category}
      </a>
      区块中
      <span style={{ float: 'right' }}>约 {item.count} 个结果</span>
    </Option>
  );
}
