使用javascript计算网页中的单词数

Question

Lets suppose i opened a page http://vedabase.net/cc/adi/9/3/en . I am using firefox and have firebug installed in it. How can i find the number of word in this web page using javascript running in the console of firebug.

Answer 1

try this

document.body.innerText.split(' ').length

for Firefox you can use (Firefox uses the W3C-compliant textContent property.)

document.body.textContent.split(' ').length

Answer 2

If you want to get rid of the blank spaces and newlines

document.body.innerText.split(/\s/).filter(function (txt) {return /\S/.test(txt)}).length;

You can see the words using

document.body.innerText.split(/\s/).filter(function (txt) {return /\S/.test(txt)});

On firefox, instead of document.body.innerText use document.body.textContent
