Question

Let’s say I have the string:

"Hello world; some random text; foo; bla bla; "

what regular expresion could I use in order to get a substring until the second ; .

In other words I will like to end up with the substring "Hello world; some random text;"

or maybe I want to get the substring until the 3th ; thus ending up with:

"Hello world; some random text; foo;"

Answer 1

Try this one. Should work just fine.

/([\w\s]+?\;){2}/

Used as follows:

var str = "Hello world; some random text; foo; bla bla; ";
var match = str.match(/([^;]*;){2}/)[0];
alert(match); // Hello world; some random text;
