JQuery breadcrumbs from single string

I have a string separated by "/" which I need to make into breadcrumbs.

I have tried this, but the x is not working.

var path = "sub1/sub2/sub3";
var breadcrumbs = path.split('/');
for(var i = 0, l = breadcrumbs.length; i < l; i++) {
    var x = path.substring(0, breadcrumbs[i].length);
    
    console.log( x );
}

x needs to be the full path from the beginning, right to the last one selected.

for example, if you were to click on "sub2" in the breadcrumbs, the value should be sub1/sub2

>Solution :

One possibility is breadcrumbs.slice(0, i + 1).join('/'):

var path = "sub1/sub2/sub3";
var breadcrumbs = path.split('/');
for (var i = 0, l = breadcrumbs.length; i < l; i++) {
  var x = breadcrumbs.slice(0, i + 1).join('/');

  console.log(x);
}
