Question

I\'m developing a Classic ASP page that pulls some content from a database and creates a Read more link after the first 100 characters as follows;

Answer 1

Here is a fairly simple approach to getting endings at the word level, and shooting for about your given limit in characters.

var limit        = 100,
    text         = $('div.contentdetail').text().split(/\s+/),
    word,
    letter_count = 0,
    trunc        = '',
    i            = 0;

while (i < text.length && letter_count < limit) {
  word         = text[i++];
  trunc       += word+' ';
  letter_count = trunc.length-1;

}

trunc = $.trim(trunc)+'...';
console.log(trunc);
