Split () in javascript

Question

I have a code:

  function _filter() {
    var url = window.location;
    alert(url);
    alert(url.split("/")[1]);
  }

When I run it, I get only one warning message:

http: // localhost: 8000 / index / 3/1 .

Why am I not getting a second warning?

Answer 1

Adding .toString()works and avoids this error:

TypeError: url.split is not a function

function _filter() {
    var url = window.location;
    alert(url);
    alert(url.toString().split("/")[2]);
}

When starting on this very page, the output is:

Answer 2

The location object is the reason for this, window.location is an object, not a string , it's location.href or location.toString ().

  function _filter() {
    var url = window.location.href; // or window.location.toString()
    alert(url);
    alert(url.split("/")[1]);
  }

Answer 3

window.location , href :

function _filter() {
  var url = window.location.href;
  alert(url);
  alert(url.split("/")[1]);
}
