Disabled button

Hello,

I have a page where, once the user enters it, I want to disable some
buttons. This because the user must select a row for them to be
accessible. To be more specific, they are edit/delete buttons. So,
basically, I want them disabled if there is no row in selected in the
table.

My problem is that I don’t know the proper component to use. This is the
way I’m trying right now:

<%= link_to image_submit_tag(“btn_delete.png”, :id => “btn_delete”,
:title => “Delete report”, :class => “btn_delete”, :disabled => true),
:action => “verify_availability” %>

The verify_availability method is in reports controller, and it verifies
if the user is able to delete that report. This will create an HTML
anchor with an input type=“image” inside. This creates another problem:
:disabled => true doesn’t work on IE (and only on IE). So, is there a
workaround for this issue?

Thanks for your time.

Hi Eduardo,

Maybe it’s just too early here, but I’m not following you. For
starters, why are you using both link_to and image_submit_tag ?

It’s kind of interesting that it’s working at all. I’d see if the HTML
being generated (using Firefox, of course) validates.

Assuming that the buttons you want to disable are, in fact, form submit
buttons, I’d lose the ‘link_to’ as a first step. Let us know what the
behavior is when you do that.

I’m using link_to with image_submit_tag justly to avoid using a form.
People often use link_to with image_tag for image links, and since both
HTML anchors and imgs can’t be disabled, I thought of using that. Note
that I’m a starter too, and if this is not the better approach please
let me know.

I’m not sure if this will help, but here is the url to all the link
rails helpers, one of them is a link_to_if which creates a link if a
condition is met.

http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html

Not sure if this helps at all, but it might be useful to create a link
IF a row is select and do something else if it is not. Also, it looks
like you can have the “disabled” attribute for a link but I was unable
to locate an example of it in use but I would imagine it would an
html_option.
