将抓取的数据组织到数组中，并从数组中选择1或2个字符串

// 创建一个空数组
var dataArray = [];

// 进行数据抓取并存储到数组中
var data1 = "字符串1";
var data2 = "字符串2";
var data3 = "字符串3";

dataArray.push(data1);
dataArray.push(data2);
dataArray.push(data3);

// 确保数据已经成功存储到数组中
console.log(dataArray);

// 从数组中选择1或2个字符串
var selectedData = [];
var randomIndex1 = Math.floor(Math.random() * dataArray.length);
selectedData.push(dataArray[randomIndex1]);

var randomIndex2 = Math.floor(Math.random() * dataArray.length);
if (randomIndex2 !== randomIndex1) {
  selectedData.push(dataArray[randomIndex2]);
}

// 对选择的字符串进行进一步处理或使用
console.log(selectedData);
