I am new to ROR. I am trying to show a "Others"
text field only if the selected value is "others". I am trying to make hide/show function to be as general as possible, since I will need it in many controller. If anyone can help enlightening me, I will really appreciate it. BTW, I am using Rails 2.1.1 ruby 1.8.7
general_info.html.erb
<div>
<%= f.label :location_id, "Location:" %>
<%= f.collection_select(:location_id, Event.locations, :id, :name, {:prompt => true},
{:onchange => remote_function(
:url => {:action => "showHideDOMOther"},
:with => "'selectedText='+this.options[this.selectedIndex].
text + '&other_div='+'loc_other'")}) %>
</div>
<div id="loc_other" style="display:none">
<%= f.label :location_others, "Others:" %>
<%= f.text_field :location_others %>
</div>
info_controller.rb
def showHideDomOther
render :update do |page|
page.showHideDOM("Others", params[:selectedText], params[:other_div])
end
end
...
application_helper.rb
def showHideDOM(targetString, selectedText, targetDiv)
if selectedText.casecmp targetString
page.hide targetDiv
else
page.show targetDiv
end
end
Seem to get the correct parameters value, but nothing seems to happen. This is what I see from the console when I changed the value of selection to "Others".
Parameters: {"action"=>"showHideDOMOther", "authenticity_token"=>"e7da7ce4631480b482e29da9c0fde4c026a7a70d", "other_div"=>"loc_other", "controller"=>"events", "selectedText"=>"Others"}
