You need to render the javascript call as an output. You can’t call it
inside the controller directly. try this in your controller:
render :update do |page|
page << “alert(‘hello world’);”
end

oh god…
render :update do |page|
page.alert(‘hello world’)
end

I have tried but it shows this message in the page:
try {
alert(“hello world”);
} catch (e) { alert(‘RJS error:\n\n’ + e.toString());
alert(‘alert(“hello world”);’); throw e }
