Ruby on Rails latest stable (v5.2.3) - 2 notes - Class: ActionView::Helpers::JavaScriptHelper

Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v4.0.2) is shown here.

link_to_function(name, function, html_options={}) public

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>

error in block code example

I guess there’s an error in this part of the code:

link_to_function("Show me more", nil, :id => "more_link") do |page|
  page[:details].visual_effect  :toggle_blind
  page[:more_link].replace_html "Show me less"

It doesn’t work. It should be:

link_to_function("Show me more", nil, :id => "more_link") do |page|
  page[:details].toggle "Blind"
  page[:more_link].replace_html "Show me less"

Using Rails 2.1.0
