如何使用JavaScript分隔字符串并将值分配给每个字符串？

Question

I have a process that returns 4 different pieces of information, each piece separated by an asterisk(*). For example, the code will return something like:

Boy*15*Winter*New Years

I want to split this string into individual and assign values to each piece.
So something like this:

var gender = Boy
var age = 15
var favoriteSeason = Winter
var favoriteHoliday = New Years

But I do not want those variables hard-coded.

Is there a way to do this using javascript?

Answer 1

In ES6, you can do this trivially with destructuring :

const [gender, age, favoriteSeason, favoriteHoliday] = 'Boy*15*Winter*New Years'.split('*');

In ES5, you need to map it a little bit, but can create objects pretty easily:

var chunks = 'Boy*15*Winter*New Years'.split('*');
return {
  gender: chunks[0],
  age: chunks[1],
  favoriteSeason: chunks[2],
  favoriteHoliday: chunks[3],
};

Either way, the core is String.prototype.split with your separator.

Answer 2

ES2015版本：

const [gender, age, favoriteSeason, favoriteHoliday] = yourVar.split('*');

Answer 3

Use split() to break up the string:

s = 'Boy*15*Winter*New Years';
a = s.split('*');
gender = s[0];
age = int(s[1])
favoriteSeason = s[2];
favoriteHoliday = s[3];

Answer 4

 var str = "Boy*15*Winter*New Years"; var array = str.split("*"); var gender = array[0]; var age = array[1]; var favoriteSeason = array[2]; var favoriteHoliday = array[3]; console.log(gender, age, favoriteSeason, favoriteHoliday)
