您可以使用下面的现有方法来设置pageLoadTimeout。在下面的例子中，如果页面加载时间超过20秒，那么它将抛出一个页面重新加载异常:

WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().pageLoadTimeout(20, TimeUnit.SECONDS);

使用这个函数

public void waitForPageLoad(ChromeDriver d){
        String s="";
        while(!s.equals("complete")){
        s=(String) d.executeScript("return document.readyState");
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        }

    }

如果你想等待一个特定的元素加载，你可以在RenderedWebElement上使用isdisplay()方法:

// Sleep until the div we want is visible or 5 seconds is over
long end = System.currentTimeMillis() + 5000;
while (System.currentTimeMillis() < end) {
    // Browsers which render content (such as Firefox and IE) return "RenderedWebElements"
    RenderedWebElement resultsDiv = (RenderedWebElement) driver.findElement(By.className("gac_m"));

    // If results have been returned, the results are displayed in a drop down.
    if (resultsDiv.isDisplayed()) {
      break;
    }
}

我使用node + selenium-webdriver(现在的版本是3.5.0)。我所做的是:

var webdriver = require('selenium-webdriver'),
    driver = new webdriver.Builder().forBrowser('chrome').build();
;
driver.wait(driver.executeScript("return document.readyState").then(state => {
  return state === 'complete';
}))

这段代码将等待页面上的所有元素都加载到DOM中。

WebDriver driver = new WebDriver();
WebDriverWait wait = new WebDriverWait(driver, timeout);

wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*")));

Imran对Java 7的回答是:

    WebDriverWait wait = new WebDriverWait(driver, 30);

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