如何在数组中的字符串中搜索子字符串，并将相关结果添加到新数组中

function searchSubstringsInArray(array, substring) {
  var results = []; // 创建新数组存储搜索结果

  for (var i = 0; i < array.length; i++) {
    var currentString = array[i];
    if (currentString.indexOf(substring) !== -1) {
      results.push(currentString); // 将包含子字符串的字符串添加到新数组中
    }
  }

  return results; // 返回搜索结果数组
}

// 示例用法
var originalArray = ["apple", "banana", "orange", "grape"];
var substring = "an";
var searchResults = searchSubstringsInArray(originalArray, substring);
console.log(searchResults); // 输出 ["banana", "orange"]
