You can make a clever use of the replace() method although you are not replacing anything.

var str = "the very long text you have...";

var counter = 0;

// lets loop through the string and count the words
str.replace(/(\b+)/g,function (a) {
   // for each word found increase the counter value by 1
   counter++;
})

alert(counter);

the regex can be improved to exclude html tags for example
