解决：UEditor在模态框中编辑时还是显示上次的内容

 //set content  when UEditor  loading success to avoid error of undefined in first times
                            self.ue.addListener("ready", function () {
                                self.ue.setContent(self.WorkPlan.content);
                            });
                            //set content of UEditor when edit again
                            self.ue.setContent(self.WorkPlan.content);

 说明：
self.ue是实例化的UEditor
注释1：使用监听是避免UEditor还未加载完毕就填充内容，导致‘innerHTML’ of undefined 错误
注释2：每次编辑时替换UEditor中的内容
效果如下：
