我有一个日期选择器，其中包含代码片段中提到的元素。在弹出的对话框中打开此日期选择器。弹出的对话框由element（by.css（'。mat-dialog-container'））标识；

但是，我无法单击“下个月”并从该日历中选择一个日期。任何帮助都会很棒！

Answer 1

使用此：

 const EC = protractor.ExpectedConditions;

        const calendar = element(by.tagName('mat-datepicker-toggle'));
        browser.wait(EC.visibilityOf(calendar), 50000);
        calendar.click();
        const next = element(by.className('mat-calendar-next-button'));
        browser.wait(EC.visibilityOf(next), 50000);
        next.click();

Answer 2

1。首先了解webtable的概念。我希望您先了解一下 mukesh otwani的动态压光机手柄教程，然后在此处应用相同的逻辑 2.单击日历图标 3.点击导航链接 4.点击日期 避免使用.all元素来遍历并选择获取陈旧元素引用错误的日期 5.使用量角器官方网站上的过滤器概念来单击一个元素，然后遍历每个非常元素并单击 6.确保您将日期作为参数传递，而不是对日期进行硬编码。 否则请尝试执行此操作，我将与您分享一些代码来克服这个问题。
