查找字符串数组中是否包含某些特定字符串

主要通过indexOf()和 push()方法实现，具体代码如下：

function search(Arr,str){  var newArr = [];  for(var k in Arr){    if(Arr[k].indexOf(str) != -1){      newArr.push(Arr[k]);    }  }  return newArr.length !=0 ? newArr : "未找到";}var arr = ["abc","acd","bcf"];var str1 = "b"; var result = search(arr,str1);console.log(result);//["abc","bcf"]var str2 = "s";var result1 = search(arr,str2);console.log(result1);//"未找到"
