我有一个基于 PHP 的分页系统,它工作正常,我使用 GET 参数来传递页码:
<?php
$db = mysql_select_db($database,$connection) or trigger_error("SQL", E_USER_ERROR);
$sql1 = "SELECT COUNT(*) FROM $table";
$result1 = mysql_query($sql1, $connection) or trigger_error("SQL", E_USER_ERROR);
$row = mysql_fetch_row($result1);
$numrows = $row[0];
$rowsperpage = 2;
$totalpages = ceil($numrows / $rowsperpage);
if (isset($_GET['page']) && is_numeric($_GET['page'])) {
$currentpage = (int) $_GET['page'];
} else {
$currentpage = 1;
}
if ($currentpage > $totalpages) {
$currentpage = $totalpages;
}
if ($currentpage < 1) {
$currentpage = 1;
}
$offset = ($currentpage - 1) * $rowsperpage;
$sql2 = "SELECT * FROM internet_security ORDER BY id DESC LIMIT $offset, $rowsperpage";
$result2 = mysql_query($sql2, $connection) or trigger_error("SQL", E_USER_ERROR);
$list = mysql_fetch_assoc($result2);
$startrow = ($currentpage-1) * $rowsperpage;
?>
我显示链接的方式是这样的:
h3>Results <?php echo ($startrow+1) ?> - <?php echo min($startrow + $rowsperpage, $row) ?> of <?php echo ($totalpages *$rowsperpage) ?></h3>
<ul><?php
if ($currentpage!=$totalpages) {
echo " <li><a href='{$_SERVER['PHP_SELF']}?page=$totalpages'>$totalpages</a></li> ";
$nextpage = $currentpage + 1;
echo " <li><a href='{$_SERVER['PHP_SELF']}?page=$nextpage'>Next»»</a></li> ";
}?></ul>
<ul><?php
if($currentpage<$totalpages){
for ($x = ($currentpage - 3); $x < (($currentpage + 3) + 1); $x++) {
if (($x > 0) && ($x <= $totalpages)) {
if ($x == $currentpage) {
echo " <li id='pcurrent'><a href='{$_SERVER['PHP_SELF']}?page=$x'>$x</a></li>";
} else {
echo " <li><a href='{$_SERVER['PHP_SELF']}?page=$x'>$x</a></li> ";
}}}
}
?> </ul>
<ul><?php
if ($currentpage > 1){
$prevpage = $currentpage - 1;
echo " <li><a href='{$_SERVER['PHP_SELF']}?page=$prevpage'>««Prev</a></li> ";
echo "<li><a href='{$_SERVER['PHP_SELF']}?page=1'>1</a></li> ";
}?></ul>
这个分页工作正常。
我的问题是我现在想向它添加 AJAX 功能,以便我应该在分页中同时拥有这两种功能,即如果 JavaScript 被关闭,分页将在 PHP 中工作。
我试过这个:
$(function() {
$('#pagination ul li a, .temp').click(function(ev) {
ev.preventDefault();
$('#temporary').load($(this).attr('href')).modal();
});
});
但是现在,分页不起作用,单击分页链接时什么也没有发生。怎么了?
