jquery insertAfter or append question
- by user271619
I am playing around with validating form inputs.
For now I'm simply having fun with displaying a message after the input.
I'm using the after() method to display simple text, and when I purposely make a mistake in the box I display the message perfectly.
However, if I purposely make a mistake again, it immediately adds the same message after the first error message.
Is there a method that replaces the original? I didn't want to try to add some more code to look for that original error message, delete it, and then insert the same message again.
I will if I have to, but I thought I'd ask first.
Here's my code:
<script language="javascript" type="text/javascript">
$(document).ready(function(){
$("form#testform").submit(function(){
if($("#fieldname1").val().length < 5){ $("#fieldone").after("<div>not enough characters</div>"); }
});return false;
});
</script>
<form id="testform" method="post">
<table>
<tr>
<td style="width:100px;">Field One:</td>
<td><input type="text" name="fieldname1" id="fieldname1" /></td>
</tr>
<tr>
<td> </td>
<td><input type="submit" name="Submit" value="Submit" /></td>
</tr>
</table>
</form>
