Empty the contents of a textarea after submit
Solution 1
$('#CommentBox').val('');
Use the val()
method, passing in an empty string.
Documentation: http://api.jquery.com/val
Also, your mark up is wrong. textarea
isn't a self-closing element. You need a </textarea>
tag. And the type="text"
isn't necessary (probably not actually valid either)
As per your edit, you can either set the IDs to be static at the top of your .aspx file (I think it's ClientID="static"
)
Or you can use a different selector:
$('textarea').filter('[id*=CommentBox]').val('');
Solution 2
You can use val
:
$("#CommentBox").val('');
JSFiddle
Edit:
You are not referencing the ASP.NET
generated text area correctly. As you have shown in your question, you need to reference it like:
$('#<%=CommentBox.ClientID%>').val('');
Solution 3
$('textarea#CommentBox').val('');

I have a comment box (textarea) inside a dialog. If the comment is successfully saved I want to clear the contents of the textarea and close the dialog box. ATM the dialog box will close but I need to wipe its contents.
<textarea id="CommentBox" type="text" runat="server" rows="7" maxlength="2000" /> if (CommentSuccessfullyUpdated == "TRUE") { //empty the comment box?? //something like $("#CommentBox").empty(); //closes the dialog box $("#dialog").dialog('close');
Thanks for any replies
Edit: Thanks for the help guys. It is running through the code but its not working. I think it has to do with in order to pick up the correct vales and resolve a biding issue I had to use:
function SubmitButton() { var commentBoxData = $('#<%=CommentBox.ClientID%>').val(); }
When run through with a breakpoint returns:
function SubmitButton() { var commentBoxData = $('#ctl00_ContentPlaceHolder1_CommentBox').val(); }
AND:
<textarea name="ctl00$ContentPlaceHolder1$CommentBox" id="ctl00_ContentPlaceHolder1_CommentBox" type="text" rows="7" maxlength="2000"> </textarea>
So Im guessing im not referencing the same textarea when I try to empty it. Also tried
$("#CommentBox.ClientID").val('');
but no joy....ay ideas?
