单击按钮后如何等待直到页面变暗？

Question

如何在点击按钮后等待页面变暗（加载）？我尝试了以下选项但尚未成功。我必须捕获交易时间。

1）隐含等待

(driver.manage().timeouts().implicitlyWait(20L, TimeUnit.SECONDS);)  

2）明确等待

(wait = new WebDriverWait(driver, 200);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("(//a[@ardbn='z3Btn_TDS_Next']/div/img)[position()<3]")));)

3）我自己的一个功能

public void waitForPageLoaded() { 

ExpectedCondition<Boolean> expectation = new ExpectedCondition<Boolean>() { public Boolean apply(WebDriver driver) { return ((JavascriptExecutor)driver).executeScript("return document.readyState").equals("complete"); } }; 

Wait<WebDriver> wait = new WebDriverWait(driver,30); try { wait.until(expectation); } catch(Throwable error) { fail("Timeout waiting for Page Load Request to complete."); } }

Answer 1

等到加载框不可见。 假设加载框的locator / id / xpath是id = loader，那么

By locator = By.id("loader");
Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)  
                    .withTimeout(timeOutInSeconds, TimeUnit.SECONDS)                    
                    .pollingEvery(pollingIntervalInSeconds, TimeUnit.SECONDS)            
                    .ignoring(NoSuchElementException.class)                     
                    .ignoring(StaleElementReferenceException.class);                    
            wait.until(ExpectedConditions.invisibilityOfElementLocated(locator));
