使用 Selenium 访问输入元素的日期文本

Question

访问网站时，此元素包含日期：20210930

<input placeholder="yyyymmdd" ng-class="{'mark-red': relatedDocument.documentDate == null}" title="yyyyMMdd" data-autoclose="1" bs-datepicker="" data-date-format="yyyyMMdd" data-date-type="number" class="form-control importInputHalf ng-valid ng-valid-date ng-valid-min ng-valid-max ng-touched ng-dirty ng-valid-parse" data-max-date="today" ng-model="relatedDocument.documentDate" ng-disabled="editDisabled || relatedDocument.documentDuplicated || (isDocumentAlreadyUsed(relatedDocument) &amp;&amp; relatedDocument.rex) || relatedDocument.correctionCloneLocked" ng-change="documentChanged(relatedDocument,'documentDate')">

但是当我尝试使用以下代码通过 Selenium 访问此信息时，它 returns 为空：

date = self.driver.find_element(By.XPATH, "// *[@id='out']/table/tbody/tr[3]/td[5]/input").text

有没有办法访问这些数据？

文本 20210930 不是 innerText 而是值内。所以 text 属性将无法检索它。您需要使用 get_attribute("value") 诱导如下：

使用CSS_SELECTOR:

print(WebDriverWait(self.driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "input[placeholder='yyyymmdd'][title='yyyyMMdd'][ata-date-format='yyyyMMdd'][data-max-date='today']"))).get_attribute("value"))

使用XPATH:

print(WebDriverWait(self.driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//input[@placeholder='yyyymmdd' and @title='yyyyMMdd'][@data-date-format='yyyyMMdd' and @data-max-date='today']"))).get_attribute("value"))

注意：您必须添加以下导入：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
