public class FeedUpdaterServlet extends HttpServlet {

public void doGet(HttpServletRequest req, HttpServletResponse resp)

        throws IOException {

    PrintWriter out = resp.getWriter();

    req.setCharacterEncoding("utf-8");

    resp.setLocale(Locale.TAIWAN);

    resp.setContentType("text/html; charset=utf-8");

    resp.setCharacterEncoding("utf-8");

    resp.getWriter().println("Hello, world!!@!");

            out.println("我是人");  //some chinese character

    out.println(resp.getCharacterEncoding());

    out.flush();

    out.close();

  }



}

<locale-encoding-mapping-list>

        <locale-encoding-mapping>

            <locale>zh_TW</locale>

            <encoding>utf-8</encoding>

        </locale-encoding-mapping>

    </locale-encoding-mapping-list>







Output: Hello, world!!@! ??? ISO-8859-1

Why is this Javascript much *slower* than its jQuery equivalent?

I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow).

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
