本文介绍了Selenium Webdriver wait预期条件失败:等待By.id定位的元素的可见性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图让Selenium Web驱动程序等待，但总是会出现异常"

I am trying to put selenium web driver wait, but always I am getting an exception "

org.openqa.selenium.TimeoutException:预期条件失败:等待By.id定位的元素的可见性:mobileNo(以100毫秒间隔尝试20秒)".

org.openqa.selenium.TimeoutException: Expected condition failed: waiting for visibility of element located by By.id: mobileNo (tried for 20 second(s) with 100 milliseconds interval)".

我将秒数增加到100，然后又遇到了同样的问题，我的ID是正确的.

I increased seconds to 100, then also getting the same problem, my id is correct.

WebDriver d = new ChromeDriver(); d.get("myurlOne"); WebElement username = d.findElement(By.id("username_id")); username.sendKeys("123"); WebElement password = d.findElement(By.id("password_id")); password.sendKeys("123"); d.findElement(By.id("loginButton")).click(); System.out.println("logged in successfully"); d.get("navigatedurl"); JavascriptExecutor js = (JavascriptExecutor)d; System.out.println("navigated to new page"); WebDriverWait wait__mob = new WebDriverWait(d, 20); try { System.out.println("Start"+new Date()); wait__mob .pollingEvery(100,TimeUnit.MILLISECONDS).until(ExpectedConditions.visibilityOfElementLocated(By.id("mobileNo"))); d.findElement(By.id("mobileNo")).sendKeys("99999999999); } catch (TimeoutException e) { // TODO: handle exception System.out.println(e.toString()); }

div代码:

<div class="form-group"> <label class="col-xs-5 control-label" for="mobileNo">Mobile No.</label> <div class="col-xs-6 leftpadding-none"> <input type="tel" class="form-control k-input" id="mobileNo" name="inputmobileNo" placeholder="" maxlength="10"> <!--required pattern="\d{10}" validationMessage="Mobile No. is Required"--> </div>

推荐答案

根据Java文档/java/org/openqa/selenium/support/ui/WebDriverWait.html"rel =" nofollow noreferrer> WebDriverWait 类，如果您想更改轮询间隔，则需要对其进行更改在 constructor 中作为构造函数如下:

As per the Java Docs of WebDriverWait Class if you want to change the Polling Interval you need to change it in the constructor as the constructor is as follows :

WebDriverWait(WebDriver driver, long timeOutInSeconds, long sleepInMillis) Wait will ignore instances of NotFoundException that are encountered (thrown) by default in the 'until' condition, and immediately propagate all others.

在尝试在元素上调用sendKeys()时继续前进，您需要调用ExpectedConditions方法 elementToBeClickable .

Moving forward as you are trying to invoke sendKeys() on the element you need to invoke the ExpectedConditions method elementToBeClickable.

所以您的代码将是:

WebDriver d = new ChromeDriver(); d.get("myurlOne"); WebElement username = d.findElement(By.id("username_id")); username.sendKeys("123"); WebElement password = d.findElement(By.id("password_id")); password.sendKeys("123"); d.findElement(By.id("loginButton")).click(); System.out.println("logged in successfully"); d.get("navigatedurl"); System.out.println("navigated to new page"); WebDriverWait wait__mob = new WebDriverWait(d, 20); try { System.out.println("Start"+new Date()); wait__mob.until(ExpectedConditions.elementToBeClickable(By.xpath("//div[@class='form-group']//label[contains(.,'Mobile No.')]//following::div[1]/input[@class='form-control k-input' and @id='mobileNo' and @type='tel']"))).sendKeys("9999999999); } catch (TimeoutException e) { System.out.println(e.toString()); }
