Some form values not getting submitted after using .replaceWith()

Let's say I have this form:







<form action="submit" method="post">

<select name="category" id="categorylist">

<option value="love">Love</option>

<option value="magic">Magic</option>

<option value="custom">Custom</option>

</select>

<textarea name="content">SomeContent</textarea>

<input type="submit">

</form>







I wanted to change the select into an input when I select custom so I came up with this:







$(function(){

  $('#categorylist').change(function(){

    $(this).replaceWith('<input type="text" name="category">');

  });

  if( $('#categorylist').val() == 'custom' )

    $('#categorylist').replaceWith('<input type="text" name="category">');

});







But when the select is changed into an input, $_POST['category'] isn't there when i dumped $_POST on form submission. Why is it so?

    You should replace the <select> with </select> and <input type="submit> to <input type="submit"> in your html. With following javascript there is no problem with .replaceWith() and submitting form.

    $(function(){
    $('#categorylist').change(function(){
    if( $('#categorylist').val() == 'custom' )
    $('#categorylist').replaceWith('<input type="text" name="category">');
    });
    });


    See my test.

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.
