Multiple comparisons in an if statement using the logical OR operator

Question

I want to do he following, but it does not work:

if(pathname == '/ik/services/' || '/ik/recruitment/'){
   //run function
}

It is completely ignoring my if statement and executes the code for all pages...

You would have to do something like this:

if(pathname == '/ik/services/' || pathname == '/ik/recruitment/'){
   //run function
}

Your || '/ik/recruitment/' would always be truthy, and therfor the code within your if-statement will always run.

Upvote for being the only answer out of five that actually explains why the OP's code doesn't work. – JJJ Apr 09 '13 at 12:01
@rrikesh Weird, I swear it worked just a minute ago. I'll try to track down another good resource on truthy/falsy and update my answer. Thanks for the heads up! – Christofer Eliasson Apr 09 '13 at 12:07

The Google Cache says it was available in March. But I find it strange that is not found right now – RRikesh Apr 09 '13 at 12:09
@DavidVanStaden My pleasure! Updated my answer with another read on truthy/falsy values, that hopefully works better. – Christofer Eliasson Apr 09 '13 at 12:15

Try

if(pathname == '/ik/services/' || pathname == '/ik/recruitment/'){

OR

jQuery inArray

Example

var arr = ['/ik/services/','/ik/recruitment/'];

if($.inArray(pathname , arr) !== -1)

This has nothing to do with jQuery, it's just a normal JS "error". You need to compare both strings with the variable:

if (pathname == 'foo'  || pathname == 'bar')

Try this:

if((pathname == '/ik/services/') || (pathname == '/ik/recruitment/')){
   //run function
}
