javascript - 转换数组

Question

如何使用Javascript打开此列表：

var array = ["no yes", "maybe certainly"];

进入这一个：

var array2 = ["no", "yes", "maybe", "certainly"]

Answer 1

如果数组元素中有多个空格的可能性，最好在这里使用regex。

1. 按空格加入数组元素
2. 使用正则表达式从字符串中提取非空格字符

var array = ["       no yes     ", "     maybe     certainly  "];

var array2 = array.join('').match(/\S+/g);

document.write(array2);
console.log(array2);

Answer 2

您可以join数组中的所有元素，然后split将其添加到数组中，就像这样

＆＃13;

// var array = ["no yes", "maybe certainly"];
var array = ["no yes     ", "    maybe    certainly"];
var array2 = array.join('').trim().split(/\s+/g);

console.log(array2);

Answer 3

var array = ["no yes", "maybe certainly"]

answer = converfunction(array);

function converfunction(array){
return array.toString().replace(',',' ' ).split(' ')
}
