java - Wicket datatable change font or css of cell after onchange -


in application have defaultdatatable, clickable column , search field filter table. filter filters content of datatable after character inserted input field. goal underline (or other css) parts of text in fields apply input of user.

example: characters 'a' , 'b' of string 'abc' should underlined if user enters 'ab'. javascript can add styling, function strange things datatable. deletes inside table tags en puts new html there. other information gone. doing wrong?

<script>     $('.searchfield').keyup(function(){         var page = $('.datatable');         alert(page.text());         var pagetext = page.text().replace("<span>","").replace("</span>");         alert(pagetext);         var searchedtext = $('#searchfield').val();         var theregex = new regexp("("+searchedtext+")", "igm");              var newhtml = pagetext.replace(theregex ,"<b>$1</b>");         alert(newhtml);         page.html(newhtml);    }); </script>

new table:

<table id="id" class="datatable" wicket:id="id"> col1 col2 123 <b>matchedchar</b> text <b>matchedchar</b> text </table>

old table (collapsed body en head):

<table id="id" class="datatable" wicketsource="url.java" wicket:id="id"> <thead wicketsource="org.apache.wicket.extensions.markup.html.repeater.data.table:datatable.java:181" wicket:id="toptoolbars"> <tbody wicketsource="org.apache.wicket.extensions.markup.html.repeater.data.table:datatable.java:207" wicket:id="body"> <tr class="even" wicketsource="org.apache.wicket.extensions.markup.html.repeater.data.table:defaultdatatable.java:71" wicket:id="rows"> </tbody> </table>

i think have handler on searchfield perform table refresh. need subcribe on complete ajax event.

wicket.event.subscribe('/ajax/call/complete', function(jqevent, attributes, jqxhr, errorthrown, textstatus) {   // call code highlight text });

you can put subscription method in page(in script tag). if want link js call specific behavior onchangeajaxbehavior, need call target.appendjavascript:

    new onchangeajaxbehavior(){         @override         protected void onupdate(ajaxrequesttarget target) {             target.appendjavascript("<call highlight function here>");         }     };

try this jquery highlight plugin. more ajax global call listeners here.

i've made simple demo can check it.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
