量角器单击如果显示不起作用使用异步等待 [英] Protractor click if displayed is not working using async await

问题描述

如果显示的量角器单击不起作用，则使用异步等待.我尝试过以下方法:

Protractor click if displayed is not working using async await. I have tried with the following method:

public static async clickIfDisplayed(targetElement: ElementFinder) {
    if (await targetElement.isPresent() && await targetElement.isDisplayed()) {
        await PageHelper.click(targetElement);
    }
}

即使元素不存在或显示，有时也会点击上面的内容.请帮助理解我在这里出错的地方.

The above sometime clicks even if element is not present or displayed. Please help to understand where I am going wrong here.

推荐答案

以下内容与 async-await 配合良好:

The following worked well with async-await:

public static async clickIfDisplayed(targetElement: ElementFinder) {
    const isPresent = await targetElement.isPresent();
    if (isPresent) {
        const isDisplayed = await targetElement.isDisplayed();
        if (isDisplayed) {
            await PageHelper.click(targetElement);
        }
    }
}
