如何等待硒中存在元素？

需要等待

ignoring

WebDriver

FluentWait<WebDriver> fluentWait = new FluentWait<>(driver)        .withTimeout(30, TimeUnit.SECONDS)        .pollingEvery(200, TimeUnit.MILLISECONDS)        .ignoring(NoSuchElementException.class);

有关更多信息，请参见FluentWait文档。但是请注意，此条件已经在ExpectedConditions中实现，因此您应该使用

WebElement element = (new WebDriverWait(driver, 10))   .until(ExpectedConditions.elementToBeClickable(By.id("someid")));

*更新为更新版本的Selenium：

withTimeout(long, TimeUnit) has become withTimeout(Duration)pollingEvery(long, TimeUnit) has become pollingEvery(Duration)

因此，代码将如下所示：

FluentWait<WebDriver> fluentWait = new FluentWait<>(driver)        .withTimeout(Duration.ofSeconds(30)        .pollingEvery(Duration.ofMillis(200)        .ignoring(NoSuchElementException.class);
