Try Something like this --- 尝试这样的事情-
jQuery.ajax({
type: "GET",
url: deleteData.php,
data:{'id':id},
success:function(results)
{
.....
}
});

You should use Ajax . 您应该使用Ajax 。 Try maybe with jQuery : 尝试使用jQuery ：
http://api.jquery.com/jQuery.ajax/ http://api.jquery.com/jQuery.ajax/
Then onSuccess method delete row using jQuery too. 然后onSuccess方法也使用jQuery删除行。

$link= mysql_connect("localhost","root","")or die("Local Host Error".mysql_error());
mysql_select_db("test");
}
function viewData()
{
$query = "SELECT * FROM test_mysql";
$resultset = mysql_query($query);
return $resultset;
}
function DeleteData($userID)
{
$query = "DELETE FROM test_mysql WHERE id=".$userID;
$resultset=mysql_query($query) ;
}
}
Step2:
delete.php
include_once'DBConnect.php';
if(isset($_REQUEST['userid']) && $_REQUEST['userid'])
{
$delObj= new DBConnect();
$delObj->DeleteData($_REQUEST['userid']);
}

使用redirect（'my_original_page.php'）它将重定向到您的主页，但应将其放置在执行删除查询之后
