Question

This jQuery doesnt appear to be working as I would expect it to:

$('#topic li a').filter(function () {
  if ($(this).text() > 410) {
    $(this).parent('li').addClass('wrap');
  }
});

The jQuery should work out if the text within an <a href=>....</a> is over 410 chars, if it is it should add the class .wrap to the parent li.

Anyone have any ideas what im doing wrong?

Answer 1

$('#topic li a').filter(function () {
  if ($(this).text().length > 410) {
    $(this).parent('li').addClass('wrap');
  }
});

When you do $(this).text() > 410 it tries to convert the text to an integer to compare, it most likely is converting the long string to a number like 0. Use .length to get the length of the string returned
