Use    textarea   val       The problem with using        textarea   text       or        textarea   html     for that matter is that it will only erase what was in the original DOM sent by the server   If a user clears it and then enters new input  the clear button will no longer work   Using  val     handles the user input case properly

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

I agree with  Jakub Arnold s answer  The problem should be somewhere else  I could not figure out the problem but found a work around   Wrap your concerned element with a parent element and cause its html to create a new element with the id you are concerned with  See below   lt div id  theParent  gt       lt div id  vinanghinguyen images bbocde  gt  lt  div gt   lt  div gt    onSelect       function event ID fileObj         theParent   html   lt div id  vinanghinguyen images bbocde  gt  lt  div gt          vinanghinguyen result   hide         uploadifyQueue   height 315

I just tried using this code and  psynnott s answer was correct though I needed to know it would work repeatedly  seems to work with jquery 1 7 1    I modified the jfiddle to the following http   jsfiddle net Rjj9v 109       mytext   text        This is not a new answer  psynnott is correct I am just providing a more concise example that shows the textarea is still working after the clear because if you use  val     the text area stops working

I believe the problem is simply a spelling error when writing bbcode as bbocde       vinanghinguyen images bbocde   val       should be       vinanghinguyen images bbcode   val

This method removes not only child  and other descendant  elements    but also any text within the set of matched elements  This is because    according to the DOM specification  any string of text within an   element is considered a child node of that element       textarea   empty
