将数组值与字符串进行比较

Question

var string1 = "Hello, World";
var arr = string1.split(",");
var string2 = "Hello World";

如何比较arr数组的值和变量string2的值？

Answer 1

只需使用join 方法如下：

var string1 = "Hello, World";
var arr = string1.split(",");
var string2 = "Hello World";
var arr_string = arr.join('');
console.log(arr_string == string2);

或者你可以试试replace如下：

var string1 = "Hello, World";
var string2 = "Hello World";
var new_string1 = string1.replace(/,/g, '');
console.log(new_string1 == string2);
