Question

我试图通过Selenium选择一个下拉框，我被告知以下

元素目前不可见，因此可能无法与
进行交互

在搜索了一下后，我尝试了以下但仍然被给予同样的错误：

        WebElement inputElement = driver.findElement(By
                .id("diningAvailabilityForm-searchTime"));

        ((JavascriptExecutor) driver).executeScript(
                "arguments[0].checked = true;", inputElement);

        ((JavascriptExecutor) driver).executeScript(
                "arguments[0].checked = true;", inputElement);

        ((JavascriptExecutor) driver)
                .executeScript("$(\"#diningAvailabilityForm-searchTime\").show()");

        ((JavascriptExecutor) driver).executeScript(
                "arguments[0].checked = true;", inputElement);

        driver.switchTo().activeElement();
        new Select(inputElement).selectByVisibleText("Dinner");

但是，这会导致相同的错误。当我在浏览器中打开页面时，我可以看到下拉列表，我也可以单击下拉列表。但是，就像我说的那样 - 使用这段代码并没有达到我的需要。

输入元素在值正确时返回。确保通过抛出一些错误来检查它是否正确，并且按预期失败。

这是HTML

Answer 1

你可能会在元素可见之前尝试使用它。

WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.refreshed(ExpectedConditions.visibilityOfElementLocated(by)));
wait.until(ExpectedConditions.refreshed(ExpectedConditions.elementToBeClickable(by)));

适合您情况的有效等待方法

如果它不起作用，你也可以尝试

waitUntil(Waits.elementDisplayed(WebElement));

Answer 2

((JavascriptExecutor) driver)
        .executeScript("document.getElementsByClassName(\"selectBox-nojs\")[1].style.display = ''");

((JavascriptExecutor) driver)
        .executeScript("document.getElementsByClassName(\"selectBox-nojs\")[2].style.display = ''");

无法在Selenium中选择下拉列表 - 元素不可见
