Question

My webpage crashes when I run this:

function replace()
{
    var str = document.getElementById('feeds');
    var cont = str.innerHTML;
    curstring = "twitter: ";
    while (cont.indexOf(curstring))
    {
        replaced = cont.replace(curstring,"TWIMG ");
        str.innerHTML = replaced;
    }
}

Answer 1

Yes there is. You never reassign cont. Perhaps try this?

function replace()
{
  var str = document.getElementById('feeds');
  var cont = str.innerHTML;
  curstring = "twitter: ";
  while (cont.indexOf(curstring) != -1)
  {
    replaced = cont.replace(curstring,"TWIMG ");
    str.innerHTML = replaced;
    cont = str.innerHTML;
  }
}
