jquery - Changing a character in a class -

i amend last character of string in particular class. is, change comma full-stop in list items belonging class last (li.last). example:

<li>one,</li> <li>two,</li> <li>three,</li> <li class="last">four,</li> 

change to:

<li class="last">four.</li> 

is there simple way this?

you can use .text overload takes function, useful if have many such elements:

$('li.last').text(function(i, text){         return text.replace(/,$/, '.'); });

note can use :last-child selector: $('li:last-child').
