How can I alert the id of the <li>
item clicked?
<ul id='myid'>
<li id='1'>First</li>
<li id='2'>Second</li>
<li id='3'>Third</li>
<li id='4'>Fourth</li>
<li id='5'>Fifth</li>
</ul>
(Anything that can replace the id may be value or something else will also work.)
$("#myid li").click(function() {
alert(this.id); // id of clicked li by directly accessing DOMElement property
alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
alert($(this).html()); // gets innerHTML of clicked li
alert($(this).text()); // gets text contents of clicked li
});
If you are talking about replacing the ID with something:
$("#myid li").click(function() {
this.id = 'newId';
// longer method using .attr()
$(this).attr('id', 'newId');
});
Demo here. And to be fair, you should have first tried reading the documentation:
