I am working with Javascript StopWatch in C# web Aplication. But I don't get output from javascript. Below is my code.







<html xmlns="http://www.w3.org/1999/xhtml">

    <head runat="server">

        <script type="text/javascript" language="JavaScript">

            var state = 0;

            function startstop() {

                if (state == 0) {

                    state = 1;

                    then = new Date();

                    then.setTime(then.getTime() - ms);

                } else {

                    state = 0;

                    now = new Date();

                    ms = now.getTime() - then.getTime();

                    document.stpw.time.value = ms;

                }

            }

            function swreset() {

                state = 0;

                ms = 0;

                document.stpw.time.value = ms;

            }

            function display() {

                setTimeout("display();", 50);

                if (state == 1)  {now = new Date();

                ms = now.getTime() - then.getTime();

                document.stpw.time.value = ms;

            }

        }

        </script>

    </head>

    <body onload="display()">

        <form id="form1" runat="server">

            <div>

                Time:

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

By User
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). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

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.
