JavaRanch is a community of people from all over the world, many of who are not native English speakers. While using abbreviations like "u" instead of spelling out "you" is convenient when text messaging your friends on a cell phone or in a chat room, it presents an extra challenge to those that are already struggling with English. Additionally, such shortcuts may confound automated translation tools that patrons of the Ranch may be making use of.

I would like to ask for your help in making the content of JavaRanch a little easier to read for everybody that visits here by not using such abbreviations.

Please read this for more information.

thanks,
bear

document.getElementById("id"+i).value != " "



Why are you checking for a single space character?

when i said



the alert just gave me an empty box, with an OK button. Hence, I was checking for single space character. Can you please advice?

What lead youto believe that an "empty box" meant a single space character?
