我在帖子中创建了一个带有新元盒的插件。php。它本身工作得很好，但问题是如果用户选择在WordPress中按“发布/更新/保存”，它将保存其值。
我尝试将JQuery函数添加到#publish 项目
这种方式是可行的，但它会带来一个恼人的问题：“您确定要离开此页面吗？”window.location.reload() 我不能在那里。
$("#publish").click(function(e) {
//e.preventDefault();
// SM Data
var data = prepareData();
if(data.length !== 0) {
for(var i = 0; i < data.length; i++ ) {
$.post( postdataAjax.ajaxurl, data[i] );
}
}
// WP Data
$.ajax({
url: "post.php",
type: "POST",
data: $("form#post").serialize(),
success: function(response,status) {
window.location.reload();
}
});
return true;
});
对于此最终解决方案，我尝试使用
window.onbeforeunload = null 诸如此类，但没有取得任何成功。
这是全部功能：
private function __construct() {
add_action( \'add_meta_boxes\', array( $this, \'add_custom_metabox\' ) );
}
public function add_custom_metabox()
{
$screens = array( \'post\', \'page\', \'landing\' );
foreach ( $screens as $screen ) {
$this->set_plugin_slug();
add_meta_box(
\'_meta\',
__( \'###\', $this->plugin_slug ),
function( $post ) {
global $slug;
$html_code = _HTML_Code::get_instance();
echo $html_code->generate_script_new_publication($post, $slug);
echo $html_code->generate_script_list($post, $slug);
}, $screen
);
}
}
...
public function generate_script_list($post, $slug)
{
global $wpdb;
$mainTable = $wpdb->prefix.\'esm\';
$data = $wpdb->get_results("SELECT * FROM $mainTable WHERE post_id = $post->ID ORDER BY publish_localtime ASC");
$d_ids = array();
foreach( $data as $item ) {
$d_ids[] = $item->id;
}
ob_start();
?>
<script type="text/javascript">

所以我的问题是，我想做的是可以实现的吗？我该怎么做？对现有函数的编辑还是完全重写？
