jquery - get url path?

Question

I know I can use window.location.pathname to return a url, but how do I parse the url?

I have a url like this: http://localhost/messages/mine/9889 and I'm trying to check to see if "mine" exists in that url?

So, if "mine" is the second piece in that url, I want to write an if statement based on that...

if(second argument == 'mine') { do something }

Answer 1

if ( location.pathname.split("/")[2] == "mine" ) { do something }

Although it would obviously be better to check whether there are enough items in the array that's returned by split:

var a = location.pathname.split("/");
if ( a.length > 2 && a[2] == "mine" ) { do something }

Note that even though array indexes are zero based, we want to specify 2 as the index to get what you refer to as the 2nd argument as split splits "/messages/mine/9889" into an array of 4 items:

["", "messages", "mine", "9889"]

Answer 2

if (window.location.pathname.split("/")[2] == "mine") {
  // it exists
};

window.location.pathname is a string at the end of the day, so the usual string methods apply.

Answer 3

You could use the string.split('/') function to create an array of items to check otherwise there are several jQuery plugins that parse the url eg

Answer 4

if jquery is an option, you could do the following:

$.inArray("mine", window.location.pathname.split("/"))
