Hi,
I have a textarea on a page, and I want to implement some simply validation, just to check that it’s not empty. If the user presses the submit button and the textarea is empty, I have a popup that I want to be displayed.
Here’s the form code:
HTML Code:
<form name="addData" method="post" action="addData.php">
<textarea name="data" cols="60" rows="10"></textarea>
<br />
<input type="submit" value="Submit">
</form>
Here’s the popup code that I would like to be displayed if the textarea is empty:
HTML Code:
<div id=popup>
<p>Look's like you forgot to leave a message! <a href=# class=hide>Hide</a> </p>
</div>I’ve tried so many tutorials and examples online, but none of them will work at all – whether I use an onClick on the Submit button, or an onSubmit on the form.
Any help to solve this would be greatly appreciated.
