在JavaScript和Jquery中如何将字符串转换为数组,并将相同的数组转换为字符串,并使用JavaScript中的typeof方法检查它们。
var arr = "abcdef".split(''); // creates an array from a string
var str = arr.join(''); // creates a string from that above array
From String to Array you can Use split()
Method
var str = "How are you doing today?";
var res = str.split(" ");
console.log(res); // How,are,you,doing,today? it will print
From Array to String you can use Join()
method or toString()
Method
If you want do it manually, without any JavaScript methods. Try the below
String to Array
var str = "STRING";
var arr = [];
for(int i=0; i<=str.length; i++)
arr[i] = str.charAt(i);
Array to String
var str = "";
var arr = ["S","T","R","I","G"];
for(int i=0; i<=arr.length; i++)
str +=arr.charAt(i);
