Question

Im learning javascript right now, so this might be a really newb question! I googled it, but didnt found what I was looking for, maybe I just didnt googled the right thing, but yeah…Oh im not using any plug-ins for cookies.

I have a cookie named “country”, the value is the user’s country code, like US, CA, UK, AU or FR…
I want to display a block of content only if the country is, let’s say DE, ES, AT, IT or NL.

The logic of what im looking for: if cookie “country” exist and country == one of the country in my array…

Im thinking about something like… But that is obviously too simple and not working 🙂

var countryArray = new Array["DE", "ES", "AT", "IT", "NL"];

if( $.cookie('country') && $.cookie('country') == countryArray ) { alert("working"); }

Answer 1

You could use indexOf for new browsers:

countryArray.indexOf($.cookie('country')) > -1

Also , instead of

 countryArray = new Array["DE", "ES", "AT", "IT", "NL"];

you need to write:

 countryArray = ["DE", "ES", "AT", "IT", "NL"];

UPDATE: For old browsers include this script in your js:

 Array.prototype.indexOf = Array.prototype.indexOf || function( value, startIndex ){
     var i = startIndex || 0;
     for(; i < this.length; ++i){
         if( value === this[i] ){
             return i;
         }          
     }
     return -1;
 }
