好吧，这是一个使用ajax导航加载的页面，页面加载得很好。我正在尝试制作它，这样当页面提交时，它就不会刷新整个页面。我四处寻找了一段时间，仍然找不到解决办法。
<head>
<script>
$(document).on('submit', '#changePassword', function() {
$("#content").load("core.home");
return false;
});
</script>
</head>
<?php if( !preg_match( "/index.php/i", $_SERVER[ 'PHP_SELF'] ) ) { die(); } ?>
<form action="" method="post" id="changePassword">
<div class="box">
<div class="boxhead purple purple">
<strong>Change password</strong>
</div>
<?php if( $_POST[ 'submit'] ) { try { $oldpassword=$ core->clean( $_POST['current_password'] ); $oldpassword_enc = $core->encrypt( $oldpassword ); $newpassword = $core->clean( $_POST['new_password'] ); $newpassword_enc = $core->encrypt( $newpassword ); if( !$oldpassword or !$newpassword) { throw new Exception(
"All fields are required." ); } elseif( $oldpassword_enc != $user->data['password'] ) { throw new Exception( "The password you entered does not match the one we have on record." ); } else { $db->query( "UPDATE users SET password = '{$newpassword_enc}'
WHERE id = '{$user->data['id']}'" ); echo "
<div class=' "square good'">"; echo "<strong>Success</strong>"; echo "
<br />"; echo "Password successfully changed!"; echo "</div>"; $db->query( "INSERT INTO logs VALUES (NULL, 'Changed Password <font color=' "51c833'"><b>Success</b></font>', NULL, '<b>{$user->data['fullUsername']}</b> ({$_SERVER['REMOTE_ADDR']})', '3') "
); } } catch( Exception $e ) { echo "
<div class=' "square bad'">"; echo "<strong>Error</strong>"; echo "
<br />"; echo $e->getMessage(); echo "</div>"; $db->query( "INSERT INTO logs VALUES (NULL, 'Changed Password <font color=' "FF0000'"><b>Fail</b></font> Reason: {$e->getMessage()}', NULL, '<b>{$user->data['fullUsername']}</b> ({$_SERVER['REMOTE_ADDR']})',
'3') " ); } } ?>
<table width="100%" cellpadding="3" cellspacing="0">
<?php echo $core->buildField( "password", "required", "current_password", "Current password" ); echo $core->buildField( "password", "required", "new_password", "New password"); ?>
</table>
</div>
<div class="box" align="right">
<button class="button" type="submit" name="submit" value="Submit" id="button">Submit</button>
</div>
</form>
<?php echo $core->buildFormJS('changePassword'); ?>
您需要使用e.preventDefault来停止提交按钮的默认行为（即在提交时重新加载）
$(document).on('submit', '#changePassword', function(e)
{
e.preventDefault();
});
