C# Selenium：等到下拉加载/显示值？

Question

I have a program in VS using C# with Selenium that inputs data into a dropdown textbox.

But the program gets an error because it takes a long time to show the value before it clicks Enter.

I'm also using ElementExists, ElementVisible, ElementClickable methods.

Is there a way to wait until the dropdown shows the value before it clicks Enter? (Is there a way to wait until the dropdown loads?)

I also increased the duration of Thread.Sleep but it's too inconsistent.

Appreciate if you could help me out. Thanks in advance.

var dropDown= wDriver.FindElements(By.XPath("//input[contains(@aria, 'false')and not(@class)]"));

dropDown.SendKeys(value);

Thread.Sleep(2000);

dropDown.SendKeys(Keys.Enter);

NOTE: (I'm not using SelectElement because the dropdown element can only be access thru Xpath.)

Answer 1

have you checked for waitForElementPresent command.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//input[contains(@aria, 'false')and not(@class)]")));

or you can use wait untill expected condition.

wait.until(
    ExpectedConditions.presenceOfNestedElementsLocatedBy(By.xpath(<"//input[contains(@aria, 'false')and not(@class)]">), By.tagName("input"))
)
