Question

我们要求使用日历作为模板列的可编辑网格，我使用以下代码，但它在运行时返回错误。我认为错误发生在下面突出显示的行。

错误：未捕获（承诺）：位置2的意外字面

当我尝试在p表中使用p日历时，我的项目中出现了完全相同的错误。我的问题是日历绑定到的ngModel对象来自http请求，因此[（ngModel）] =“ myDate”的运行时类型是字符串。

我如何解决此问题：

this.myObject = get(); if (myObject.myDate) { myObject.myDate = new Date(myObject.myDate); }

之所以使用if语句，是因为new Date（null）返回1969年的某个日期（特别是Date.getTime为0的日期），而不是null。

角度数据表，日历可编辑
