我一直在研究如何在Selenium webdriver中处理AJAX。有很多解决方案,但是否存在一个最好且正确的解决方案呢?
目前为止我看到的解决方案有:
1) 使用线程休眠 2) waitFor方法 3) ExpectedCondition 4) FluentWait 5) PresenceOfElementLocated
谢谢!

// poll every 1/3 second for 3 seconds
int timeout = 3; // seconds
int pollFreq = 3; // times per second
WebDriverWait wait = new WebDriverWait(driver, timeout, 1000/pollFreq);
// to be safe, test (driver instanceof JavascriptExecutor) here
JavascriptExecutor executor = ((JavascriptExecutor) driver);
// Check to see if jQuery is available first
Boolean hasJquery = (Boolean) executor.executeScript("return !!window.jQuery");
Boolean hasActive = (Boolean) executor.executeScript("return typeof window.jQuery.active === \"number\"");
if (hasJquery && hasActive) {
// Wait for JS AJAX calls to complete...
wait.until((ExpectedCondition<Boolean>) driver -> (Boolean) executor
.executeScript("return window.jQuery.active === 0"));
// JS AJAX calls completed.
// Good idea to add a timing report here for troubleshooting.
}
// else jQuery/active-prop not available, continue
我已经使用过这个,它本身等待的功能很好。
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
谢谢,试一下。
