html标签的class属性里面怎么嵌入变量

Question

        var id = snapshot.val().id;

        var content = snapshot.val().content;

        var textObj = '<div class="task-item">\

                        <input type="checkbox" />\

                        <span class="ui-icon ui-icon-clock"></span>\

                        <span class="task-content">'+content+'</span>\

                        <span class="task-detail">&nbspdetail</span>\

                        </div>';

我想把第一行的id变量（是一个数字）加到第三行div标签的class属性里面，可以直接嵌进去吗？
