Hi,

I want to validate if the last character of a field is '+' sign or not.

How can I achieve that?

Thanks and Regards,

if(a.charAt(a.length-1) != '+'){

        alert('Message') ;

return false ;

}

This would do it:

     var str = "Hello world!-";
       var res = str.substring(str.length-1, str.length );
if(res == '+')
alert( 'we got a +');
else
alert('no +...');

slice(-1) function returns the last character of a string.

Example:

var sd = g_form.getValue('short_description');

  alert(sd.slice(-1));

You can get the last character of the string and compare it is "+" or not.

Thanks,
