split() in javascript

I have code:

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

When I launch it I get only one alert message:

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

Why I don't get the second alert message?

The index [1] is in between the two slashes of http:// which is null and wont be alerted. Index [2] is the localhost:8000 you're probably looking for.

Simple window.location.hostname should be useful too.

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 run on this very page, the output is:

The location object is the cause of this, window.location is an object not a string it is the location.href or location.toString().

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

The value of window.location is not a string, you want the href property of the location object:

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

Because your url is ans object so you need to convert this to string than you apply split function 

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

url.split("/")[1] will equal to null. So, it alert(null) will not display msg.

To understand how many pieces you get from splitting operation you can alert the .lenght of url.split, are you sure that the script doesn't block?

Use firebug to understand that
