What is the difference between " and " in JavaScript?



I saw this question and I am wondering about the same thing in JavaScript.





If you use the character ' or the character " when making strings in JavaScript, the application seems to behave the same. So what is the difference between these two characters?





The only advantage I have seen in using ' to build strings is that I can do stuff like:







var toAppend = '<div id="myDiv1"></div>';







Instead of:







var toAppend = "<div id=\"myDiv1\"></div>";







Is there any significant difference between them that I should be aware of?

  1. They are equivalent for all intents and purposes. If you want to use either one inside a string, it is a good idea to use the other one to create the string, as you noted. Other than that, it's all the same.

  2. There's no difference. The reason for its existence is exactly what you mentioned

  3. Your example is the best example to describe the difference between the two....

  4. I think there is another difference. If you do the following

    var str1 = 'The \' character';
    var str2 = 'The " character';
    var str3 = "The ' character";
    var str4 = "The \" character";
    document.write (str1.replace("'","%26");
    document.write (str2.replace('"',"%22");
    document.write (str3.replace("'","%26");
    document.write (str4.replace('"',"%22");


    The document.write will fail for str1 and str4. That is the difference, but I don't know if there is a workaround to make them work.

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). 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

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.
