Answer 1

您可以使用此功能，适用于所有浏览器

＆＃13;

＆＃13;

var nString = 'ABC1:ABC2:ABC3:ABC4';
var result = nString.split(/:(.+)/).slice(0,-1);
console.log(result);

＆＃13;

＆＃13;

＆＃13;

Answer 2

let a = 'ABC1:ABC2:ABC3:ABC4'
const head = a.split(':', 1);
const tail = a.split(':').splice(1);

const result = head.concat(tail.join(':'));
console.log(result); // ==> ["ABC1", "ABC2:ABC3:ABC4"]

Answer 3

您可以使用indexOf和slice：

＆＃13;

＆＃13;

var a = 'ABC1:ABC2:ABC3:ABC4';

var indexToSplit = a.indexOf(':');
var first = a.slice(0, indexToSplit);
var second = a.slice(indexToSplit + 1);

console.log(first);
console.log(second);

＆＃13;
