<ul>
  <li>foo</li>
  <li>bar</li>
</ul>

<script>
$('li').each(function(index) {
    var qq=$(this).text();
    alert(index + ': ' + qq);
  });


alert(qq);// Asking this one.
</script>

Answer 1

You’ve declared qq inside the scope of the function. Once that function exits, qq doesn’t exist anymore.

If you want to have an alert for qq, you need to declare it outside of the function. Keep in mind that it will only contain the last value that was assigned to it.

var qq;

$('li').each(function(index) {
    qq=$(this).text();
    alert(index + ': ' + qq);
  });

alert(qq); // Will alert 'bar'
