java - Selenium，Java-按类查找表(无 ID)

Question

我有这样的东西:

  <table class="table">
    <thead>
    <tr>
        <th>Role</th>
        <th>Description</th>
        <th>Access</th>
        <th>Grant</th>
    </tr>
    </thead>
    <tbody>
    <tr ng-repeat="role in roles">
        <td>{{role.role_name}}</td>
        <td>{{role.role_description}}</td>
        <td><input type="checkbox" ng-model="role.allow_access" ng-change="updateAllow(role)" ng-disabled="!(role.grantor_allow_grant == 'Y' || haveAllAdminRoles)" ng-true-value="'Y'" ng-false-value="'N'"></td>
        <td><input type="checkbox" ng-model="role.allow_grant" ng-change="updateAllow(role)"  ng-disabled="!(role.grantor_allow_grant == 'Y' || haveAllAdminRoles)" ng-true-value="'Y'" ng-false-value="'N'"></td>
    </tr>
    </tbody>
</table>

如何使用 WebDriver 或 WebConnector 找到此表？我尝试过这样的事情:

WebElement table = driver.findElement(By.className("table"));

它不起作用，我收到错误:

org.openqa.selenium.NoSuchElementException: Unable to locate element:

感谢您的帮助。

这可能是由于时间问题造成的。您可以使用显式等待来等待表加载或可见

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement table = wait.until(ExpectedConditions.presenceOfElementLocated(By.className("table")));
// or
WebElement table = wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("table")));
