Say you have a <textarea>
and you want to retrieve info about the number of:
function wordCount( val ){
var wom = val.match(/\\S+/g);
return {
charactersNoSpaces : val.replace(/\\s+/g, '').length,
characters : val.length,
words : wom ? wom.length : 0,
lines : val.split(/\\r*\\n/).length
};
}
// Use like:
wordCount( someMultilineText ).words; // (Number of words)
