Question

  $("p.author").text(function() {
     return $(this).text().replace(/(By|on)/g, '');
  });

I found this on an earlier post which describes how to remove the word “By” from an element ‘p.author’

what I want to do is remove the a word from a title

something like this?

  v = $('.datarow .location').attr('title').replace(/,/g,'');
  $("span.name").attr('title').(v);

Answer 1

$('.datarow .location').attr('title', function(index, attr){
  return attr.replace(/,/g,'');
});

.attr() accepts a function as a second parameter, and gives us the old value of attr as it’s second argument.
