Return focus to field when validation fails.If the

[Jacqui1811]

Hy guys.
I have a few textboxes that need to be numerical.
The on blur event fires an isNumerical javascript function.
If the value is not numerical I show an alert box stating that the value needs to be numerical. Problem is that I want to return focus to that field and at the moment it just moves on to the next one.
Hope you can help. Code is below :

Here is the function.
<script language="javascript" type="text/javascript">
function isNumeric(textBox, boxName)
{
if(isNaN(textBox.value))
{
alert("The input needs to be numerical for field " + boxName);
textBox.focus();
return false();
}
}
</script>

Here is the calling code.
<asp:textbox id="txtNoEpisodes" size="2" maxlength="3" runat="server" onblur="isNumeric(this, 'txtNoEpisodes')"></asp:textbox>

Thanks in advance.

just do this:

onblur="return isNumeric(this);"

you don't need to pass in the textbox's name, you can access it in the function in this manner:

alert("The input needs to be numerical for field " + textBox.name);

and don't forget to change your function declaration to this:

function isNumeric(textBox)
