Question

i need to get the language that the user is using based on the document.location

urls are of the type:

domain.com/en/blabla.html
domain.com/es/blabla.html
domain.com/it/blabla.html

so i was trying like this:

function getLan(){
   var idioma = document.location;
   var idiomaTmp = idioma.split("/");
   return = idiomaTmp[1];
}

but (i don’t understand but) i get this error at firebug

idioma.split is not a function
[Detener en este error] var idiomaTmp = idioma.split("/"); 

any idea why? or maybe a better solution?

Answer 1

document.location is an Object. Although is does have a custom toString method, so that alert(document.location) shows the actual url, it itself is not a String, and String methods don’t work on it. What you want is to convert this Object to a String before using String methods:

document.location.toString().split(...) etc

As for a better solution, try regular expressions:

var m = document.location.toString().match(/\/([a-z][a-z])\//)
language = m ? m[1] : "default";
