如何为动态表元素找到正确的等待命令？

Question

网站是 https://www.nseindia.com/get-quotes/derivatives?symbol=AARTIIND

我使用“wait.until(ExpectedConditions...”等待“选项链”元素加载，然后单击它。此后会出现一个表格，但尽我所能，我无法让程序等待它加载加载，除了粗略的 Thread.sleep 命令。

我尝试过底行写着“tot”，右上角写着“底层：”，但它们似乎都在表格之前加载。我尝试过“numberOfElementsToBeMoreThan”并放置“tr”xpath的定位器，如下所示：

try {
            wait.until(ExpectedConditions.numberOfElementsToBeMoreThan(By.xpath("/html/body/div[10]/div[1]/div/section/div/div/div/div/div[1]/div[2]/div/div/div/div[2]/div[2]/div[2]/div/table[1]/tbody/tr"), 10));
        } catch (Exception e) {
        

有什么办法可以做到这一点吗？我不明白“陈旧”属性，这有什么用吗？

**Solution 1:**  

  Please try the below mechanism, actually, it will be polling every second and it stops the polling once you it get the desired element, it might work for you.
    
    FluentWait<WebDriver> wait = new FluentWait<> (driver)
      .withTimeout (10, TimeUnit.SECONDS)
      .pollingEvery (1, TimeUnit.SECONDS)
      .ignoring (NoSuchElementException.class);
    
    // Define the locator of the element to be clicked
    By locator = By.id("");
    
    // Wait until the element is clickable
    WebElement element = wait.until (ExpectedConditions.elementToBeClickable (locator));
    
    // Click on the element
    element.click();

**Solutions 2:**

here you can use if-else condition to wait for until desired element.

boolean WaitforThisElement=driver.findelement(By.xpath("pass the path of the waiting elememnt").isDisplayed();
if(WaitforThisElement==true)
{
//write the code for the further activities.

}
else
{
//wait for the 10 seconds.
Thread.wait(10000);
}
