我是 Selenium 的新手,在使用 Chrome WebDriver 和 xpath(以及通过复制完整的 xpath)单击按钮时遇到了一些困难。我已经搜索并阅读了其他帖子,但仍然不确定出了什么问题。我已经尝试使用 By.className 和 By.cssSelector 函数,但仍然无法正常工作。
还尝试让 webdriver 等待...
这是我的代码(通过检查源提取 xpath > 检查元素 > 复制 xpath):
WebDriverWait wait = new WebDriverWait(webDriver, 30);
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//[@id='contentPageWrapper']/div[2]/count-survey-component/div/div[3]/div/button/)")));
webDriver.findElement(By.xpath("//*[@id='contentPageWrapper']/div[2]/count-survey-component/div/div[3]/div/button/)")).click();
这是我得到的错误

我也尝试过使用 javascript 执行器:
JavascriptExecutor executor = (JavascriptExecutor)webDriver;
executor.executeScript("arguments[0].click();","//[@id='contentPageWrapper']/div[2]/count-survey-component/div/div[3]/div/button/");
随后出现此错误:

这是来源
<button class="pull-right mat-blue mat-raised-button ng-star-inserted" mat-raised-button=$0>
<span class="mat-button-wrapper">Add new</span>
<div class="mat-button-ripple mat-ripple" matripple=""></div>
<div class="mat-button-focus-overlay"></div>
</button>
谁能帮帮我?
提前致谢!
最佳答案
首先,确保该元素已经存在并且在您尝试单击时处于正确的状态。最佳做法是等到它可以点击。喜欢
new WebDriverWait(webdriver, 10)
.until(ExpectedConditions.elementToBeClickable(element);
element(click);
关于java - 无法使用 Selenium(Java、Chrome WebDriver)单击按钮,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/58967926/
