Assuming that people entering the string leave spaces after punctuation
- commas, full-stops, exclamation marks, etc....
I've often had to tweak routines like this because people didn't.
Depends on how accurate you need it, though; the code below will be
thrown slightly by dashes, em-dashes (debatable as to whether they're
counted as words) and people typing immediately after punctuation:
e.g.
correct : "I went out last night. I had a great time, but I'm tired
today! Can't wait til work ends - but that's 5 hours away" [ only the
dash will skew this ]
incorrect, but regularly types : "I went out last night.I had a great
time,but I'm tired today!Can't wait til work ends-but that's 5 hours
away" [a few words discounted because of the lack of spaces after ".,!"
Makes me wonder how the word-processors handle these, although I suspect
they have "approximately" at the end ?
If you need an approximation, though, [the other] Liam's solution will
do nicely.

or if you really do want it as a plugin
Plugin:
(function($){
$.fn.stringCount = function() {
var string = this.text();
var count = string.split(" ");
var result = count.length;
return result
}
})(jQuery);
Use:
$(function(){
alert( $("span.string").stringCount() );
});

you don't need a plugin, this will do it
var string = $("span.string").text();
var count = string.split(" ");
alert(count.length);

Hi all,
Any jquery plugin can check number of word in a string instead using
of .length?...
Many thanks.
