Question

我不是专家程序员。请帮助我任何人。谢谢。我正在尝试从表中加载数据库值。但是当运行程序数据无限滚动时，一次又一次地复制数据。当表数据到达end时我需要停止滚动。不需要复制数据。 `

<?php
include('connect.php');
$page = (int) (!isset($_GET['p'])) ? 1 : $_GET['p'];
# sql query
$sql = "SELECT * FROM job_posting";
# find out query stat point
$start = ($page * $limit) - $limit;
# query for page navigation
if( mysql_num_rows(mysql_query($sql)) > ($page * $limit) ){
  $next = ++$page;
  $hy=mysql_num_rows(mysql_query($sql));
  $limit=$hy;
}
$query = mysql_query( $sql . " LIMIT {$start}, {$limit}");
if (mysql_num_rows($query) < 1) {
  header('HTTP/1.0 404 Not Found');
  echo 'Page not found!';
  exit();
}
?>

您正在设置表格中记录数量的限制。

var str = $('#receiving-box-table tr:last-child td:first-child input').attr("id");
var prev_char = parseInt(str.replace("courier_tracking_no_", ""));

评论上面的代码并将$ limit设置为开头的任何数字，如

  $hy=mysql_num_rows(mysql_query($sql));
  $limit=$hy;

数据库值到达时如何停止无限滚动？
