Hi all.
If In my view I have:
<%= text_field_tag(''name'','''',:onfocus
=> "for (var i=1;i<99999;i++){};"
%>
I''d expect to have this html:
<input name="name" onfocus="for (var
i=1;i<99999;i++){};" />
instead I have:
<input name="name" onfocus="for (var
i=1;i<99999;i++){};" />
And obviously the javascript code does not work...
I also tried this:
<%= text_field_tag(''name'','''',:onfocus
=> "for (var
i=1;i<99999;i++){};".html_safe %>
but the output is the same
Thanks to all.

Hi Only one solution you should use method ''tag'' directly https://github.com/rails/rails/blob/39b9c943b7ec5181c19461d319d8c610ea1bf941/actionpack/lib/action_view/helpers/tag_helper.rb#L65 Because escape = true by default for ''text_field_tag'' https://github.com/rails/rails/blob/c091fae21f32250b19475f124c3b680dbbc163d9/actionpack/lib/action_view/helpers/form_tag_helper.rb#L170 P.S: Do not use inline JS .

These codes are not static but depend on ruby variables values. I can''t figure out how to pass a ruby variable into an external css or js file... So I have to keep all the code in one big (sigh!) rhtml... -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This is accomplished by using HTML5 data attributes. Say you have a Ruby variable x: HTML ------------ <div id="my_div" data-x="my_ruby_value">My content</div> JavaScript ------------ function myFunction() { var x = $(''#my_div'').data("x"); // Do something with x } Ryan Bates did a Railscasts episode on a few techniques to keep your JavaScript unobtrusive and yet still have access to your Ruby data: http://railscasts.com/episodes/324-passing-data-to-javascript -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

But $(''#my_div'').data("x") is not working form me, I had to do this: HTML: <div id="my_div" data-x=''<%= my_ruby_var %>''> JS: var div=document.getElementById(''my_div''); var x = div.getAttribute("data-x"); Btw, I think I could remove all Javascript code by rhtml by using this. But what about css? Could something like that be done with css? I have inline css with the :style attribute where I put my ruby variable: (...) :style => "width:" + my_ruby_var + "px" (...) If i want to do a separate css file, how can I access to this ruby variable from inside the .css ?
