internet explorer 9 - Count number of words in string using JavaScript -

i trying count number of words in given string using following code:

var t = document.getelementbyid('mso_contenttable').textcontent;  if (t == undefined) {   var total = document.getelementbyid('mso_contenttable').innertext;                 } else {   var total = document.getelementbyid('mso_contenttable').textcontent;         } counttotal = cword(total);     function cword(w) {   var count = 0;   var words = w.split(" ");   (i = 0; < words.length; i++) {     // inner loop -- count     if (words[i] != "") {       count += 1;     }   }    return (count); } 

in code getting data div tag , sending cword() function counting. though return value different in ie , firefox. there change required in regular expression? 1 thing show both browser send same string there problem inside cword() function.

you can make clever use of replace() method although not replacing anything.

var str = "the long text have...";  var counter = 0;  // lets loop through string , count words str.replace(/(\b+)/g,function (a) {    // each word found increase counter value 1    counter++; })  alert(counter); 

the regex can improved exclude html tags example
