How to handle localization in JavaScript files?

Question

I want JavaScript code to be separated from views.
I got the requirement to implement localization for a simple image button generated by JavaScript:

<         


        

Answer 1

If you insist on keeping it separate, you could do something like:

//keep all of your localised vars somewhere
var title = '{title_from_server}';
document.getElementById('someImage').title = title;

Remember, if you use JavaScript code to initialize any text of elements, your site will degrade horribly where JavaScript isn't available.
