Splitting data-attribute before second hyphen

Question

Hi guys I am trying to look at a string which looks like this:

'sl-test-one-two'

.
I want to split this string into looking like this:

'sl-test'

. I am trying to do this by matching a regex to the data-attribute which i am being returned, but I cant seem to get it right.

My code:

var breadcrumbBrand = $(".breadcrumb-navigation__link").last().attr("data-category-id");



var test = breadcrumbBrand.match(\A[^-]+-[^-]+);



console.log(test);

Answer 1

you can use the regex

^[^-]+\-[^-]+

check the demo here

function matchStr(str){
    console.log(str.match(/^[^-]+\-[^-]+/g));
}

matchStr('sl-test-one-two');
