我相信他们可能是更好的方法......是否可以使用加载更多按钮将项目形式复制table1(column)
到25 个数据行块中?table2(column)
我该怎么做?我在哪里可以找到这方面的信息?谢谢你。
我希望这能帮到您。您可以在 php 中实现它以加载更多操作。
每次单击更多按钮后,在mysql查询中更改偏移量和限制
INSERT INTO table2 SELECT * FROM table1 LIMIT 0, 25;
load more...
INSERT INTO table2 SELECT * FROM table1 LIMIT 25, 25;
load more...
INSERT INTO table2 SELECT * FROM table1 LIMIT 50, 25;
……
……
完整的代码。
1.只需将以下代码复制并粘贴到page1.php中
<div id='message'></div>
<a href='#' id='LoadMore' >Load More</a>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"
type="text/javascript"></script>
<script>
$(function() {
var page = 1;
$("#LoadMore").click(function(){
$.ajax({
type:"GET",
url:"page2.php",
data:{page:page},
success: function(response) {
$("#message").append(response);
page++;
}
});
});
});
</script>
2.在page2.php中复制以下代码
并在前两行更改 mysql_server、mysql_user、mysql_password、database_name 参数
<?php
//set argument as your mysql server
$connect = mysql_connect("mysql_server","mysql_user","mysql_password");
mysql_select_db("database_name",$connect);
$page = isset($_GET["page"]) ? $_GET["page"] : 1;
$limit = 25;
$offset = ($page - 1) * $limit;
$sql = "INSERT INTO table2 SELECT * FROM table1 limit $offset, $limit";
mysql_query($sql);
$rows = mysql_affected_rows();
echo "$rows rows added to table2 from table1<br>";
?>
3.在浏览器中运行page1.php...并将数据加载到table2
现在显示来自 table2 的数据,无需根据需要刷新页面(user2714387 在评论中说)
4.将以下代码复制粘贴到page3.php中
<table width="300" border="1" id='data_grid'></table>
<a href='javascript://' id='LoadMore' >Load More</a>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"
type="text/javascript"></script>
<script>
$(function() {
var page = 1;
$("#LoadMore").click(function(){
$.ajax({
type:"GET",
url:"page4.php",
data:{page:page},
success: function(response) {
$("#data_grid").append(response);
page++;
}
});
});
});
</script>
4.在page4.php中复制以下代码
<?php
//set argument as your mysql server
$connect = mysql_connect("mysql_server","mysql_user","mysql_password");
mysql_select_db("database_name",$connect);
$page = isset($_GET["page"]) ? $_GET["page"] : 1;
$limit = 25;
$offset = ($page - 1) * $limit;
$sql = "SELECT * FROM table2 limit $offset, $limit";
$result = mysql_query($sql);
$numRows = mysql_num_rows($result);
if($numRows>0) {
while($row = mysql_fetch_array($result)) {
//get field data and set to the following row
echo "<tr><td>field 1</td><td>field 2</td><td>field 3</td></tr>";
//edit row as you table data
}
} else {
echo "<tr><td colspan='3'> No more data </td></tr>";
}
exit;
?>
6.在浏览器中运行page4.php
