Passing a string to javascript function

Question

Simple question. How do I pass a string to a javascript function and make a popup box alert containing the contents of that string? Here's what I have:

The test.html.erb file.

<%= link_to 'Test','#', onclick: 'test(helloworld)', class: "btn btn-xs btn-primary" %>

Here's the test.js file:

function test(name){
     alert(name);
}

However, when I click on the "Test" link that gets generated, "helloworld" doesn't pop up. Nothing happens.

onclick: 'test(helloworld)'

would pass the variable named helloworld to the function. Instead, you want to pass a string literal, like:

onclick: 'test("helloworld")'

Wrap helloworld in quotes when you pass it in:

onclick: 'test("helloworld")'

I imagine there is some kind of error in the console as well.
