Jquery 第一次单击任何图像…；我的代码没有'；似乎没有更新

我使用这段代码将默认附件显示设置设为“无”，这是我第一次单击任何图像。它没有更新为“无”

jQuery('body').on('click','.thumbnail',function () {
            if(wp.media.view.Settings.AttachmentDisplay){
                var _AttachmentDisplay = wp.media.view.Settings.AttachmentDisplay;
                wp.media.view.Settings.AttachmentDisplay = _AttachmentDisplay.extend({
                    render: function() {
                        _AttachmentDisplay.prototype.render.apply(this, arguments);
                        this.$el.find('select.link-to').val('none');
                        this.model.set('link', 'none');
                        this.updateLinkTo();
                    }
                });
            }
            if(wp.media.view.Settings.Gallery){
                var GalleryDisplay=wp.media.view.Settings.Gallery;
                wp.media.view.Settings.Gallery = GalleryDisplay.extend({
                    className: "collection-settings gallery-settings",
                    template: wp.media.template("gallery-settings"),
                    render: function() {
                        GalleryDisplay.prototype.render.apply( this, arguments );
                        this.$el.find('select.link-to').val('none');
                        this.model.set('link', 'none');
                    }
                });
            }
        });
