Hi All,
I got RJS error: TypeError: element is null while using ajax.
I used in view
<%=
periodically_call_remote(:url=>{:action=>''get_user_list'',
:id=>''1''},
:frequency => ''5'') %>
in controller
render :update do |page|
page.replace_html ''chat_area'', :partial =>
''chat_area'', :object
=> [@chats, @user] if @js_update
end
in partial chat_area
<% if !@chats.blank? && !show_div(@chats).blank?%>
<% show_div_id=show_div(@chats) %>
<% for chat in @chats %>
<div class="popup" id="chat_area_<%= chat.id
%>"
style="display:<%= (chat.id == show_div_id)? ''block'' :
''none'' %>;">
<% form_remote_for(:chat, :url =>
{:controller=>''chats'',
:action=>''create'', :id=>1}, :html=>{:name =>
"form_#{chat.id}"},
:complete=>"resetContent(''#{chat.id}'');") do |f|
%>
<div style="display:none;">
<%= f.hidden_field :sessionNo, :value=>chat.sessionNo %>
<%= f.text_area :chatContent, :id=>
"chatContent_field_#{chat.id}", :cols=>"100",
:rows=>"6",
:onKeyPress=>"return submitenter(this,event);" %>
</div>
<input type="image"
src="images/chat/send-hover.png"
value="Send" onclick="return submit_button(''<%=
chat.id %>'')"/>
<% end %>
</div>
</div>
<% end %>
<% else %>
<div class="popup" id="chat_area_none"
style="display:''block'';">
<input type="image" disabled ="disabled"
src="images/chat/send.png" style="cursor:default;"
value="Send" />
</div>
<% end %>
Any help is appreciated.
Regards,
Salil Gaikwad

Hi All, I find it out why it happens because I didn''t close div above the "chat_area" properly. the only thing i did isclose the div and it works like a magic, neways thanks to all Reagrds, Salil Gaikwad -- 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 would have shown your missing /div immediately. Alternatively you can paste the html of the page into the w3c html validator for checking but this is much less convenient.
