我在 jquery 中尝试了空选择器,但它不起作用。内容仍在显示中。我正在从 SQL 数据库中检索一些行。如果没有数据库,那么我不想显示该 div。
<div id="scrollingText">
<div class="scrollWrapper">
<div class="scrollableArea">
<marquee behavior="scroll" direction="left">
<p>
<?php
$con = mysql_connect("localhost","fraptech_test","");
mysql_select_db("fraptech_test", $con);
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysql_select_db("fraptech_ndsnotice", $con);
$result = mysql_query("SELECT * FROM ndsnotice");
while($row = mysql_fetch_array($result))
{
echo $row['Notice'];
}
?>
</p>
</marquee>
</div>
</div>
</div>
