对于动态添加的元素(Firefox除外),滚动条不会触发Mouseup:

CSS:

#dBox {
    height: 100px;
    width: 230px;
    overflow - y: auto;
}

HTML:

<input type="text" id="s">

JQuery的:

$(function() {
    $('#s').focus(function() {
        var $dbox = $('<ul id="dBox"></ul>');
        for (i = 0; i < 10; i++) $dbox.append('<li>' + i + '</li>');
        $(this).after($dbox);
        $dbox.bind("mouseup", function() {
            alert('in: ');
            //console.log ('in: ');  
        });
    });
});
// OR LIKE THIS
$('#s').focus(function() {
    var $dbox = $('<ul id="dBox"></ul>');
    for (i = 0; i < 10; i++) $dbox.append('<li>' + i + '</li>');
    $(this).after($dbox);

});
$('#dBox').live("mouseup", function() …

$s = explode (" ", microtime());
$s = $s[0]+$s[1];
$con = mysqli_connect ('localhost', 'test', 'pass', 'db') or die('Err');

for ($i=0; $i<1000; $i++) {

  $stmt = $con -> prepare( " SELECT MAX(id) AS max_id , MIN(id) AS min_id FROM tb ");
  $stmt -> execute();
  $stmt->bind_result($M,$m);
  $stmt->free_result();
  $rand = mt_rand( $m , $M ).'<br/>';

  $res = $con -> prepare( " SELECT * FROM tb WHERE id >= ? LIMIT 0,1 ");
  $res -> bind_param("s", $rand);
  $res -> execute();
  $res->free_result();
}

$e = …

如果可行,我如何获取两个结果集:

$sth=$dbh->prepare("SELECT * FROM tb1 WHERE cond1;
                    SELECT * from tb2 Where cond2");
$sth->execute();
$row=$sth->fetchAll();  print_r ($row);

这是两个完全不同的表(没有共同的fiels).
