Firefox: -i cant drag the popup window (in IE i can) IE: - when i drag the popup over a selectlist the list comes through the popup!!?? - i cant make my popups invisible (these are divs) - i cant highlight or refresh a div with ajax for invisible i use this: <td class="window_close"> <span class="close"> <a href="#" onClick="changeSty(''info'',''noshow_link'');">Close</a> </span> </td> function changeSty(id, newClass){ item=document.getElementById(id); item.className=newClass; } .noshow_link { visibility: hidden; display: none; } for highlight i do this <%= form_remote_tag ( :url => { :action => :create, :id => @caller_id }, :update => "div_error" , :loading => ''item_loading()'', :complete => "updated(); changeSty(''info'',''noshow_link''); new Ajax.Updater(''list'', ''/callerids/list/?page=#{@page}&ajax_update=true'', {asynchronous:true, evalScripts:true}); new Effect.Highlight(''callerid#{@caller_id.id}'');" ) %> <%= render_partial ''form'' %> <%= submit_tag("Create", :id => ''form-submit-button'') %> <span id=''busy'' style="display: none">Creating...</span> <%= end_form_tag %> the functions function changeSty(id, newClass){ item=document.getElementById(id); item.className=newClass; } function updated() { $(''form-submit-button'').disabled = false; Element.hide(''busy''); } function item_loading() { $(''form-submit-button'').disabled = true; Element.show(''busy''); } ------------------- when i created this local with firefox everything works as it should, when i put it online i get bugs :s can anyone help me with this? thx
