Javascript Ajax使用Php加载更多/显示更少onClick按钮
下面是使用Jquery/ajax从mysql数据库获取数据的代码 我有加载更多的按钮在它是没有任何问题的工作。 但我想添加显示较少的按钮也我怎么可以添加？ （假设每次“加载更多”单击时显示12条记录。当我单击“加载更多”时，它将显示24条记录，并且它还应显示“显示更少”按钮 当用户单击“显示较少”按钮时，剩余的记录数将为12，显示较少的按钮应隐藏。如果用户多次单击“显示较多”按钮，显示较少的按钮将相应工作，则仅当仅剩余记录数等于12时，该按钮才会隐藏。） 有人能帮我在我的代码或更好的代码中添加showless按钮吗 PHPJavascript Ajax使用Php加载更多/显示更少onClick按钮,javascript,php,jquery,ajax,Javascript,Php,Jquery,Ajax,下面是使用Jquery/ajax从mysql数据库获取数据的代码 我有加载更多的按钮在它是没有任何问题的工作。 但我想添加显示较少的按钮也我怎么可以添加？ （假设每次“加载更多”单击时显示12条记录。当我单击“加载更多”时，它将显示24条记录，并且它还应显示“显示更少”按钮 当用户单击“显示较少”按钮时，剩余的记录数将为12，显示较少的按钮应隐藏。如果用户多次单击“显示较多”按钮，显示较少的按钮将相应工作，则仅当仅剩余记录数等于12时，该按钮才会隐藏。） 有人能帮我在我的代码或更好的代码中添加s

好的解决方法如下：
我所做的是我制作了两个脚本，一个用于加载更多记录，另一个用于加载更少记录，但是get\u moredata.php
是相同的
在get_moredata.php
中，我做了如下两个查询：
if(isset($_POST['lastids'])) { //this id is for View Less
$lastid_less = mysql_real_escape_string($_POST['lastids']); //this id is for View Less
$query = mysqli_query($dba, "SELECT * FROM mybooklibrary WHERE id <= '".$lastid_less."'-12");
}else if(isset($_POST['lastid'])) { //this id is for View More
$lastid_more = mysql_real_escape_string($_POST['lastid']); //this id is for View More
$query = mysqli_query($dba, "SELECT * FROM mybooklibrary WHERE id > '".$lastid_more."' limit 12");
}
if（isset（$\u POST['lastids']）{//此id用于无视图
$lastid\u less=mysql\u real\u escape\u string（$\u POST['lastids']）；//此id用于无视图
$query=mysqli_query（$dba，“从mybooklibrary中选择*，其中id为“”。$lastid_更多。“'limit 12”）；
}
因此，它会在单击按钮时运行脚本
