JavaScript: window.location.indexOf not working
Question by Guest | Last update on 2021-06-13 | Created on 2016-03-27
I would like to check my current URL with JavaScript in order to see whether a specific string is part of the address.
For this, I am using the function indexOf in the following way:
var s = window.location;
alert(s.indexOf("localhost"));
The problem is that nothing happens with this code. I even do not get any error message, nothing. What am I doing wrong? In my opinion, I am using the function in the right way, or?

The problem with this is that window.location is an object and not a string. And the object window.location does not know the function .indexOf() so that you cannot use it.
Therefore, you have to convert window.location into a string first to make it work. For example like that:
var s = window.location.toString(); alert(s.indexOf("localhost"));With this approach, it should work.
Here you can find further possibilities for converting window.location to a string.
