Question

我希望驱动程序等到元素可见或存在，但它根本不起作用！以下代码

it('shows events in "Event overview"', function(){
        driver.findElement(By.css('#bs-example-navbar-collapse-1 > ul > li:nth-child(2) > a')).click();
        driver.wait(function () {
            return driver.isElementPresent(By.css('body > div.container > div > div.events-container.ng-scope > div:nth-child(1) > div.row.row-event.detailed-view > div.col-xs-9.col-sm-9.col-md-10'));
        }, 3000);
});

给我以下错误

driver.isElementPresent is not a function

为什么呢？我从这里复制了答案：Selenium WebDriver wait till element is displayed。其他答案也不起作用。我应该展示更多我的代码吗？我在客户端项目上工作，我不想发布客户端的名称。

Answer 1

I have already answered here for this issue

For consistency with the other Selenium language bindings, WebDriver#isElementPresent() and WebElement#isElementPresent() have been deprecated. It has been completely removed from Selenium v3

因此，如果您正在使用Selenium3并希望等到所需元素存在，则应尝试使用webdriver.until，如下所示： -

const until = webdriver.until;

var el = driver.wait(until.elementLocated(By.css('body > div.container > div > div.events-container.ng-scope > div:nth-child(1) > div.row.row-event.detailed-view > div.col-xs-9.col-sm-9.col-md-10')), 3000);

Answer 2

尝试以下方法：

        return driver.findElements(By.css('body > div.container > div > div.events-container.ng-scope > div:nth-child(1) > div.row.row-event.detailed-view > div.col-xs-9.col-sm-9.col-md-10')).size() != 0;

isElementPresent不是函数
