问题描述
有人可以帮助我理解为什么我的代码无法通过ID查找元素.下面的代码:
Can someone help me understand why my code fails to find the element by ID. Code below:
from selenium import webdriver
driver=webdriver.Firefox()
driver.get('https://app.waitwhile.com/checkin/lltest3/user')
element = driver.find_element_by_id("guestPhone")
检查元素清楚地显示了ID.
Inspecting element shows the ID clearly.
<input type="tel" name="guestPhone" id="guestPhone" class="form-control ng-pristine ng-empty ng-invalid ng-invalid-phone-validator ng-invalid-required ng-touched" ng-model="form.model" ng-model-options="{ 'updateOn': 'default blur', 'debounce': { 'default': 350, 'blur': 0 } }" uib-typeahead="guest.phone for guest in form.onChange({value:$viewValue})" typeahead-min-length="6" typeahead-on-select="form.onSelect({guest:$item})" typeahead-select-on-exact="true" uib-tooltip="Please enter valid number. Include country code for non-US numbers" tooltip-trigger="'none'" tooltip-is-open="(form.guestForm.$submitted || form.guestForm.guestPhone.$touched) && form.guestForm.guestPhone.$invalid" tooltip-placement="bottom" ng-required="::form.required" phone-validator="US" placeholder="Mobile phone" title="Please enter a valid phone number" autocomplete="nope" next-on-enter="" aria-autocomplete="list" aria-expanded="false" aria-owns="typeahead-47-2884" required="required" style="">
P.S.我也尝试过XPath和名称.还是没有运气.
P.S. I've also tried XPath and name as well. Still no luck.
推荐答案
您需要等待该元素在页面上可见.您可以说它是动态加载的,因为如果右键单击chrome页面并查看源代码,您将看到没有guestPhone元素.它已使用javascript加载
You need to wait for the element to become visible on the page. You can tell this is loaded in dynamically because if you right-click on the page in chrome and view source you'll see there's no guestPhone element. It gets loaded in with javascript
以下是 http://isaacviel.name/中的示例使网络驱动程序等待元素变得可见/:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
element = WebDriverWait(driver, 10).until(
EC.visibility_of_element_located((By.ID, "myDynamicElement"))
)
finally:
driver.quit()
