Is it possible to have a fuction that will allow one space between words but no more?

For instance, I have a Comments field that I would like for the users to input text into. I already have checks to see whether the field is blank or not, but I was wondering whether there was a function that would allow something like:
“This is a test” but it would not allow
“This

is a test” since there is more than one white space between “This” and “is” rather than just one space?

Any help is appreciated ?

Would I have to hard code the text, or could I use something like:

[CODE]return /s{2,}/[/CODE] as a function?

@RodionGorkMar 09.2012 — Surely you need not hardcode the text being tested (it would be strange solution), but what you have written would not do (you want to return regexp object itself - why?). For function try passing the text as an argument to your function (bit obvious, yeah?):

[CODE]
function haveConsecutiveSpaces(t) {
return /s{2,}/.test(t);
} // haveConsecutiveSpaces

alert(haveConsecutiveSpaces("Here they aren't")); //alerts "false"
alert(haveConsecutiveSpaces("Here they are")); //alerts "true" (I hope)
[/CODE]

Try something like this (and I recommend to read a little from google "javascript regular expressions"). Write if I missed something.

Success!
