如何使用 Java Selenium 单击 AngularJS 链接？

Question

我在 Java 中使用 Selenium WebDriver。我做了大部分事情，但我被困在某一点上，我有以下 HTML 代码：<a ng-href="#/studyenrollments/new" ng-show="canCreate" class="btn btn-primary edit-btn" href="#/studyenrollments/new">New Study Enrollment</a>我试过以下方法：//new study enrollmentdriver.findElement(By.linkText("New Study Enrollment")).click();    driver.findElement(By.xpath("/html/body/div[2]/div[3]/a")).click();((JavascriptExecutor)driver).executeScript("document.querySelector(\"body > div.container.page.ng-scope > div.text-right.ng-scope > a\")");我希望点击“新研究注册”按钮并进入下一页以完成注册过程

Answer 1

检查元素是否在框架内如果是 - 然后 - 首先选择框架 -

Select Frame    name or id of iframe

然后执行以下操作 -

WebDriverWait wait = new WebDriverWait(driver, 10);

wait.until(ExpectedConditions.elementToBeClickable(By.xpath(".//a[@ng-show='canCreate']"))).click();

如果没有框架那么你可以直接与元素交互 -

WebDriverWait wait = new WebDriverWait(driver, 10);

wait.until(ExpectedConditions.elementToBeClickable(By.xpath(".//a[@ng-show='canCreate']"))).click();

Answer 2

您需要添加显式等待条件，尤其是在处理包含 Angular JS 元素的页面时

 WebElement newStudyEnrollment= driver.findElement(By.xpath("//a[contains(text(),'New 

      Study Enrollment')]"));

    WebDriverWait wait = new WebDriverWait(driver, 10);

    wait.until(ExpectedConditions.elementToBeClickable(newStudyEnrollment));

    newStudyEnrollment.click();
