WordPress codex forbulk_edit_custom_box, 还有这个bulk edit example 使用下面的JavaScript创建一个所选帖子ID的数组，以通过更新帖子的AJAX调用发送。

$bulk_row.find( \'#bulk-titles\' ).children().each( function() {
    $post_ids.push( $( this ).attr( \'id\' ).replace( /^(ttle)/i, \'\' ) );
});

我的列表表有元值的输入字段，内联快速编辑工作成功，但批量编辑失败。调试时，我发现$post\\u ids数组为空，因为我的页面上没有ID为的元素#bulk-titles.

那么我的问题是#bulk-titles 元素来自，为什么我的页面没有它们？

$( \'#bulk_edit\' ).live( \'click\', function() {

    // define the bulk edit row
    var $bulk_row = $( \'#bulk-edit\' );

    // get the selected post ids that are being edited
    var $post_ids = new Array();

    $bulk_row.find( \'#bulk-titles\' ).children().each( function() {
        $post_ids.push( $( this ).attr( \'id\' ).replace( /^(ttle)/i, \'\' ) );
    });

    // get the custom fields
    var $item_thickness = $bulk_row.find( \'input[name="item_thickness"]\' ).val();
    var $item_width = $bulk_row.find( \'input[name="item_width"]\' ).val();
    var $item_length = $bulk_row.find( \'input[name="item_length"]\' ).val();

    // save the data
    $.ajax({
        url: ajaxurl, // this is a variable that WordPress has already defined for us
        type: \'POST\',
        async: false,
        cache: false,
        data: {
            action: \'manage_wp_posts_using_bulk_quick_save_bulk_edit\', // this is the name of our WP AJAX function that we\'ll set up next
            post_ids: $post_ids, // and these are the 2 parameters we\'re passing to our function
            item_thickness: $item_thickness,
            item_width: $item_width,
            item_length: $item_length
        }
    });

});
