    vinanghinguyen_final_bbcode = '';
    vinanghinguyen_link = '';
    vinanghinguyen_final_derect_link = '';

      'auto'      : false,
      'multi'     : true,
      'buttonText': '',

      'onComplete': function(event, ID, fileObj, response, data) {
        vinanghinguyen_bbcode = '[IMG]' + 'http://cnttvnn.com' + response + '[/IMG]' + '\n';
        vinanghinguyen_final_bbcode = vinanghinguyen_final_bbcode + vinanghinguyen_bbcode;
        vinanghinguyen_derect_link = 'http://cnttvnn.com' + response + '\n';
        vinanghinguyen_final_derect_link = vinanghinguyen_final_derect_link + vinanghinguyen_derect_link;

        $("#vinanghinguyen_images_bbocde").val('').val(vinanghinguyen_final_bbcode);
      //$("#vinanghinguyen_images_derect_link").val(vinanghinguyen_final_derect_link);
        $("#vinanghinguyen_result").show();
        $(".uploadifyQueue").height(5);
      },

      'onSelect': function(event, ID, fileObj) {
        $("#vinanghinguyen_images_bbocde").val('');
        $("#vinanghinguyen_result").hide();
        $(".uploadifyQueue").height(315);
      },
    });
  });
</script>

When you do $("#vinanghinguyen_images_bbocde").val('');, it removes all the content of the textarea, so if that's not what is happening, the problem is probably somewhere else.

It might help if you post a little bit larger portion of your code, since the example you provided works.

  • Which version are you using? It works fine for me. jsfiddle.net/MD33Z
  • Hi,select an answer from the 9 answers you have so far, or post an answer if you found the solution so we can benefit from your question. Thank you.
  • Technically, this clears the textarea and adds a space back into it.
  • Thanks for negging my answer even though its the only one with a working fiddle and it is indeed still correct. Perhaps you should try going to the fiddle and swapping text to val and watch it break after the first change before incorrectly negging answers
  • I didn't neg it. I don't know who did. I was just giving an explanation as to why someone might have.
  • Fair enough, did you try the fiddle yet? since it does break my answer is still correct
  • That's interesting. Using .val('') seems to break your fiddle, but it doesn't make the text area "stop working". If you type in the text area, it works, and you can get the value from it for a form. Apparently you just can't append to it.
  • Maybe you can explain it? Don't just answer, learn to explain everything.
  • Actually it's document.getElementById("id_goes_here").innerHTML = ""; # is a jQuery selector. But good job on posting the native JS version.
