I have simple issue -- I would like to check a field to see if it's numeric if it is not blank. I'm not using any additional plugins, just jQuery. My code is as follows:
if($('#Field').val() != "")
{
if($('#Field').val().match('^(0|[1-9][0-9]*)$'))
{
errors+= "Field must be numeric.<br/>";
success = false;
}
}
...It doesn't seem to work. Where am I going wrong?
Thanks, George
