I had the following in the <head> of a GSP

<script type="text/javascript>
    $("button.remove-item").click(function() {
        $.ajax({
            url: "${createLink(action: 'remove', controller: 'cart')}",
            type: 'POST'
        });
    });
</script>

Notice that I'm using the Grails createLink tag to construct the URL that the AJAX request will post to. When I moved this code into checkout.js and replaced the block of code above with:

<script type="text/javascript" src="${resource(dir: 'js', file: 'checkout.js')}"></script>

the createLink tag is no longer evaluated by Grails. So it seems that Grails tags within <script> blocks are evaluated, but tags within .js files included by GSPs are not - is there a way to change this?

Check out the GSParse plugin to have css and js parsed as a gsp file:

You are right .js files are not evaluated by grails! but the GSP are! so thats why when u were setting a tag it was working. I would suggest you to have a differente approach of how to grab that link! as u are using jquery I would do like this:

<input type="button" class="remove-item" data-url="${createLink(action: 'remove', controller: 'cart')}" value="GO" />

checkout.js:

$("button.remove-item").click(function() {
    $.ajax({
        url: $(this).data('url'),
        type: 'POST'
    });
});
