I know this topic is discussed many a times in past but i m stuck and not getting any solution though i feel i m making some silly mistake here... Here is the snippet of code.... When i click on checkbox named "all" it gives javascript error as "object expected".... Can anybody tell me where i m going wrong ? seems like its not calling function on onclick event.Basically what i want is, when user click first check box rest of the checkboxes should be clicked automatically. CGI_info(tag_table_options => "border=1" ,error_label_bgcolor => "#EEEEEE" ,valid_bgcolor => "#EEEEEE" ,submit_label => "Search" ,title => 'Workflow for searching some text ',pre_tagtable_html => $javascript,);my $javascript = <<" JAVASCRIPT";// here i m calling select_all function but devnet is not allowing me to do so.... JAVASCRIPTTAG_info(all =>[ html => "",is_required => "false",],content =>[ html => "",is_required => "false",],url =>[ html => "",is_required => "false",],);
