以下是脚本：

我正在使用函数loadImages 在下面的脚本中，通过AJAX加载现有的附加图像，然后只需将图像ID传递给函数，它就会打开一个预填充的模式。

var frame,
selection = loadImages(images);

$(\'#stag_images_upload\').on(\'click\', function(e) {
    e.preventDefault();

var options = {
    title: \'<?php _e("Create Featured Gallery", "stag"); ?>\',
    state: \'gallery-edit\',
    frame: \'post\',
    selection: selection
};

frame = wp.media(options).open();

frame.menu.get(\'view\').unset(\'cancel\');
frame.menu.get(\'view\').unset(\'separateCancel\');
frame.menu.get(\'view\').get(\'gallery-edit\').el.innerHTML = \'<?php _e("Edit Featured Gallery", "stag"); ?>\';
frame.content.get(\'view\').sidebar.unset(\'gallery\'); // Hide Gallery Settings in sidebar

// when editing a gallery
overrideGalleryInsert();
frame.on( \'toolbar:render:gallery-edit\', function() {
    overrideGalleryInsert();
});

frame.on( \'content:render:browse\', function( browser ) {
    if ( !browser ) return;
    // Hide Gallery Settings in sidebar
    browser.sidebar.on(\'ready\', function(){
        browser.sidebar.unset(\'gallery\');
    });

    // Hide filter/search as they don\'t work
    browser.toolbar.on(\'ready\', function(){
        if(browser.toolbar.controller._state == \'gallery-library\'){
            browser.toolbar.$el.hide();
        }
    });
});

// All images removed
frame.state().get(\'library\').on( \'remove\', function() {
    var models = frame.state().get(\'library\');
    if(models.length == 0){
        selection = false;
        $.post(ajaxurl, { ids: \'\', action: \'stag_save_images\', post_id: stag_ajax.post_id, nonce: stag_ajax.nonce });
    }
});

function overrideGalleryInsert(){
    frame.toolbar.get(\'view\').set({
        insert: {
            style: \'primary\',
            text: \'<?php _e("Save Featured Gallery", "stag"); ?>\',
            click: function(){
                var models = frame.state().get(\'library\'),
                    ids = \'\';

                models.each( function( attachment ) {
                    ids += attachment.id + \',\'
                });

                this.el.innerHTML = \'<?php _e("Saving...", "stag"); ?>\';

                $.ajax({
