How to calculate number of words with given price?

Thanks.

it is a bit unreliable to calculate the price clientside since that could easyly be modified by the user - so to have a solid calculation you would need a serverside calculation too. to give the user a price-preview you might do it with javascript ... a simple approach would be to retrieve the text from the textarea and then the number of the words is roughly:

var textareaNode = document.getElementById('textareaId');
var noOfWords = textareaNode.value.split(' ').length;

this would give you the 'wordcount' depending on whitespace-separated 'character-groups' ... in case you would need more specific rules to count the words like 'she's' should be two words? then you would need a bit more preparing processing of the text.

That solution is too basic. What about surrounding whitespace and double-spaces? Sometimes that double-space might even start looking like a triple-space! :p


You should trim the whitespace off of the edges and condense the internal whitespace, THEN split the string. I'd make it into a function. Hell, I'd add it to the String object. In fact, I shall. :3


Functions:

String.prototype.trim = function() {
  return this.replace(/^\s+/,'').replace(/\s+$/,'');
}
 
String.prototype.condense = function() {
  return this.replace(/\s+/,' ');
}
 
String.prototype.words = function() {
  return (this.trim().condense().split(' ')).length;
}

Test:

alert(("  this is   a test    string    ").words());

Result:

5

of course - i just wanted to show a start - it could even be extended to find out divided words etc.

No doubt. :)
