将Char数组转换为String

Question

如何在JavaScript中将字符数组转换为字符串？

var s = ['H', 'e', 'l', 'l', 'o'];
// How to convert s to a string?

Answer 1

用途join:

string = s.join("");

Answer 2

你这样做:

var str = s.join();

Answer 3

或者使用String.

var string = String([1,2,3]);

Answer 4

join命令使您可以在数组中的项目之间设置令牌。

示例1：

function print(str) {
  $("#result").append("<p>" + str + "</p>");  
}

print(["A", "B", "C"].join()); // "A,B,C"
print(["A", "B", "C"].join("-")); // "A-B-C"
print(["A", "B", "C"].join("||")); // "A||B||C"
print(["A", "B", "C"].join("")); // "ABC"
