使用 Selenium 和 Java 無法單擊網站上的按鈕

Question

我使用 selenium java 代碼運行測試用例。

我的網頁有一個名為“Select Assets”的按鈕，xpathfinder 插件顯示為//*[@id="modalButton"]我希望單擊它。 請參閱下面的快照：

我嘗試了一些代碼來讓點擊工作，但他們都沒有點擊按鈕。

driver.findElement(By.xpath("//*[@id=modalButton]")).click();
driver.findElement(By.id("modalButton")).click();

對於上述 Java 代碼，我收到以下錯誤。

Exception in thread "main" org.openqa.selenium.NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//*[@id=modalButton]"}

下面是顯示按鈕代碼的網頁的view source 。

<div class="help-block"></div>
</div>                    </div>
                    
                    
                    <div class="row">
                        <div class="col-lg-6">
                            <h2>List of Server/Devices to be tested</h2>
                        </div>

                        <div class="col-lg-3 col-lg-offset-3">
                            <button type="button" id="modalButton" class="btn btn-primary" value="/synvm/basic/web/index.php?r=security-test-request0.000000map-asset&amp;request_type=ConfigReviewReq&amp;param=CR&amp;series_id=0" style="float:right;">Select Assets</button>                        </div>
                    </div>
                    <br>

你能建議什么可以幫助我點擊按鈕嗎？

Answer 1

嘗試用 JSExecutor 點擊

public void clickWithJS(WebElement element) {
        JavascriptExecutor js = (JavascriptExecutor) driver;
        js.executeScript("arguments[0].click();", element);
    }

在您的情況下，Webelement 應該是：

WebElement element = driver.findElement(By.id("modalButton"));
