javascript - 如何创建用于二维数组搜索的函数？

Question

请帮帮我，我有一个搜索一维数组的函数，这里是源代码和它们的变量:

var fruits= ["Apple","Banana","Grape","Orange"];

function searchStringInArray (src1,fruits) 
{
  var res=""
  for (var j=0; j<src1.length; j++) {
    if (src1[j].match (searched)) 
    {
    res=res+src1[j]+","
    }
}
    return res;
} 
alert(searchStringInArray (src1,'Grape')); 

但我想修改函数来搜索多维数组，使用以下变量:

var fruits= [
    ["001","Apple","For John"],[["002","Banana","For Stuart"],["003","Grape","For Collins"],["004","Orange","For Ben"]
    ];

函数大概是怎样适合变量的？

Answer 1

您可以使用 Array.prototype.find()结合 Array.prototype.includes() :

const fruits = [
  ["001", "Apple", "For John"],
  ["002", "Banana", "For Stuart"],
  ["003", "Grape", "For Collins"],
  ["004", "Orange", "For Ben"]
]

const searchStringInArray = (src1, searched) => src1.find(arr => arr.includes(searched))
  
console.log(searchStringInArray(fruits, 'Grape'))
