未捕获的typeError无法读取未定义可视编写器的属性“attributes”

Question

我有一些视觉作曲家的问题。由于旧版本，无法获得支持。顾客不会付钱。问题是我不能在后端添加元素。chrome调试出错：

我已经尝试用代码修复这个问题:未捕获TypeError:无法读取未定义的属性'attributes‘

<pre>

and alot fo load script errors
</pre>

代码：

html2element: function(html) {
var $template, attributes = {},
    template = html;
$template = $(template(this.model.toJSON()).trim()), _.each($template.get(0).attributes, function(attr) {
    attributes[attr.name] = attr.value
}), this.$el.attr(attributes).html($template.html()), this.setContent(), this.renderContent()
},

我已经检查了所有的网络和堆栈溢出，我不能找到这个问题的问题。

最好的解决方案是替换html2element代码，并将composer视图中的代码呈现为以下代码

html2element: function(html) {
            var attributes = {},
                $template;
            if (_.isString(html)) {
                this.template = _.template(html);
                $template = $(this.template(this.model.toJSON(), vc.templateOptions.default).trim());
            } else {
                this.template = html;
                                $template = $(this.template(this.model.toJSON(), vc.templateOptions.default).trim());
            }

            _.each($template.get(0).attributes, function(attr) {
                attributes[attr.name] = attr.value;
            });
            this.$el.attr(attributes).html($template.html());
            this.setContent();
            this.renderContent();

        },
        render: function() {
            var $shortcode_template_el = $('#vc_shortcode-template-' + this.model.get('shortcode'));
            if ($shortcode_template_el.is('script')) {
                this.html2element(_.template($shortcode_template_el.html()));
            } else {
                var params = this.model.get('params');
                $.ajax({
                    type: 'POST',
                    url: window.ajaxurl,
                    data: {
                        action: 'wpb_get_element_backend_html',
                        data_element: this.model.get('shortcode'),
                        data_width: _.isUndefined(params.width) ? '1/1' : params.width,
                        _vcnonce: window.vcAdminNonce
                    },
                    dataType: 'html',
                    context: this
                }).done(function(html) {
                    this.html2element(html);
                });
            }
            this.model.view = this;
            this.$controls_buttons = this.$el.find('.vc_controls > :first');
            return this;
        },
