Compare with:

link_to_function(name, function, html_options={})

Returns a link whose onclick handler triggers the passed JavaScript.

The helper receives a name, JavaScript code, and an optional hash of HTML options. The name is used as the link text and the JavaScript code goes into the onclick attribute. If html_options has an :onclick, that one is put before function. Once all the JavaScript is set, the helper appends “; return false;”.

The href attribute of the tag is set to “#” unless html_options has one.

link_to_function "Greeting", "alert('Hello world!')", class: "nav_link"
# => <a class="nav_link" href="#" onclick="alert('Hello world!'); return false;">Greeting</a>

Parameters

name req
function req
html_options opt = {}
