javascript - 如何将字符串组用单引号引起来

Question

我需要将数组的元素导出为字符串，但在元素周围保留单引号。如您所见，将它们导出到 toString() 方法输出 Banana, Orange, Apple, Mango 但我需要像 'Banana', '橙色”、“苹果”、“芒果”。

var fruits = ["Banana", "Orange", "Apple", "Mango"];
var map = fruits.toString();

console.log(map);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

我该怎么做？

Answer 1

ES6

var fruits = ["Banana", "Orange", "Apple", "Mango"];
// creates a new array containing: ["'Banana'", "'Orange'", "'Apple'", "'Mango'"]
var exportedFruits = fruits.map(fruit => "'" + fruit + "'");
console.log(exportedFruits.toString())

ES5

var fruits = ["Banana", "Orange", "Apple", "Mango"];
// creates a new array containing: ["'Banana'", "'Orange'", "'Apple'", "'Mango'"]
var exportedFruits = fruits.map(function(fruit){
  return "'" + fruit + "'";
});
console.log(exportedFruits.toString())
