如何为动态表元素找到正确的等待命令？-解网

问：

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

这是我的代码：

driver.get("https://www.nseindia.com/get-quotes/derivatives?symbol=AARTIIND");
try {
    wait.until(ExpectedConditions.elementToBeClickable(By.id("optionChain")));
} catch (Exception e) {
}
driver.findElement(By.id("optionChain")).click();
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) {
}
Thread.sleep(10000);
List<WebElement> table = driver.findElements(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"));
int optionChainSize = table.size();

我想删除 Thread.sleep（）命令，但它总是以 optionChainSize = 0 结束。

我使用“wait.until（ExpectedConditions...”等待“选项链”元素加载，然后单击它。此后出现一个表，但尽我所能，我无法让程序等待它加载，除了一个粗略的 Thread.sleep 命令。

我试过写着“tot”的底行，右上角写着“Underlying：”，但它们似乎都只是在表格之前加载。我尝试了“numberOfElementsToBeMoreThan”并放置了“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) {

有什么方法可以做到这一点吗？我不明白“陈旧”属性，这有用吗？

java html selenium-webdriver webdriverwait

    **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 the if-else condition to wait for until desired element.

//add loop 
for(i=0;i<=10)
{
    boolean WaitforThisElement=driver.findelement(By.xpath("pass the path of the waiting elememnt").isDisplayed();
    if(WaitforThisElement==true)
    {
    //write the code for the further activities.
    

//if the desired element is found it cannot move to the else block and will end the loop and come out from the loop and move to the next code.

    }
    else
    {
    //wait for the 10 seconds.
    Thread.wait(10000);
//Increase the loop count
i++
    }

}
