通常出现在chrome驱动程序中的元素不可点击错误也恰好在firefox中显示。显示错误消息：

  Exception in thread "main" org.openqa.selenium.WebDriverException: Element is not clickable at point (141, 299.29998779296875). Other element would receive the click: <div class="showOnTop" id="loadingPanelContainer"></div>

Answer 1

您应该等待元素可点击，您可以使用：

WebDriverWait wait = new WebDriverWait(driver, 30); 
wait.until(ExpectedConditions.elementToBeClickable(By.<your locator>));

或者有时你甚至需要将鼠标悬停在元素上以使其可点击。你可以这样做：

String mouseOverScript = "if(document.createEvent){var evObj = document.createEvent('MouseEvents');evObj.initEvent('mouseover', true, false); arguments[0].dispatchEvent(evObj);} else if(document.createEventObject) { arguments[0].fireEvent('onmouseover');}";
            ((JavascriptExecutor) driver).executeScript(mouseOverScript,
                     driver.findElement(By.<your locator>));

完成此操作后，您可以尝试：

正常点击（）功能：

driver.findElement(By.<your locator>).click();

OR

非原生javascript执行者：

JavascriptExecutor executor = (JavascriptExecutor) driver;
executor.executeScript("arguments[0].click();",  driver.findElement(By.<your locator>));

Prateek的回答是正确的。然而，我在最新版本的Firefox和Selenium 2.50.1中注意到的一点是，它并不总是能够成功地将元素滚动到视图中。

如果您的问题是元素从屏幕滚动（并且因此在标题栏之类的内容下滚动），您可以尝试将其滚动到视图中，如下所示：

private void scrollToElementAndClick(WebElement element) {
    int yScrollPosition = element.getLocation().getY();
    js.executeScript("window.scroll(0, " + yScrollPosition + ");");
    element.click();
}

如果需要，还可以添加静态偏移量（例如，如果页面标题高200像素且始终显示）：

    public static final int HEADER_OFFSET = 200;

    private void scrollToElementAndClick(WebElement element) {
    int yScrollPosition = element.getLocation().getY() - HEADER-OFFSET;
    js.executeScript("window.scroll(0, " + yScrollPosition + ");");
    element.click();
}
