How to extract specific words from a string with some patterns?

I am trying to extract some strings from a word with some pattern like –

"38384-1-page1-2222", "1-22-page33-02", "99-222-frontpage-111"

how will I extract all word between - separately, means first word before - and then second word between - and - and so on…

string = "38384-1-page1-2222";
string.substr(0, string.indexof("-")); //return 38384

But how will I extract 1, page1 and 2222 all the words separately?

>Solution :

The javascript function str.split(separator) split the string by the given separator and it returns an array of all the splited string. REF Here

Here is an example following your question :

var string = "38384-1-page1-2222";
var separator = "-";

var separated = string.split(separator);

var firstString = separated[0];  // will be '38384'
var secondString = separated[1]; // will be '1'
var thirdString = separated[2];  // will be 'page1'
/* And So on ... */
