使用硒在动态表中搜索字符串

时间：2019-06-22 03:41:08

标签： python selenium xpath css-selectors webdriverwait

我有一个动态表，其中一个列/字段的标题为“引用ID”。该表是动态的，但列不是动态的。我想获取所有参考ID作为字符串。

下面是字符串“参考ID”所在的单元格的摘要。如果单击此单元格，它将以升序或降序对动态表进行排序（取决于单击的次数）。

编辑：在下面包含了整个表头

<th tabindex="0" scope="col" id="NUMBER_headerCell_2" aria-sort="none" class="PagingGridLayout---align_start headCell_2" abbr="Reference ID">
    <div id="NUMBER_column2_header" class="GridHeaderCell---grid_header_text">Reference ID<span class="GridHeaderCell---accessibilityhidden">Sortable column, activate to sort ascending</span></div>
</th>

我检查了代码并复制了Xpath。我试图查看是否可以单击参考ID单元格，以便对列表进行排序。

reports = browser.find_element_by_xpath("//*[@id='NUMBER_headerCell_2']")
reports.click()

但是，我得到一个错误：

  

NoSuchElementException：消息：没有这样的元素：无法找到   元素：

我在这里有点挠头。不知道该怎么办。任何帮助将非常感激。 ：）

4 个答案:

答案 0 :(得分：1)

由于您知道元素的ID，因此最好使用：

reports = browser.find_element_by_id('NUMBER_headerCell_2')
reports.click()

看看是否可行！

答案 1 :(得分：1)

由于我无法发表评论，因此我必须在此处执行此操作。

想法-1选择父节点。例如，您尝试访问的 th 在一个类中。抓住该类元素grab_class= br.find_elements_by_class('class_name') 然后在其中找到grab_elements=grab_class.find_elements_by_(anything you feel like)

之类的元素

Idea-1抓住页面中的所有Thead / Th元素，然后手动访问列表。让我们假设您想要的元素是5th，然后选择lis [4]并对其进行操作。

只是可以做些什么的粗略草图。我希望它会有用。

NOTE查找元素时要小心。 find_element给出单个和第一个对象匹配条件，其中find_elemments返回所有WebElement的列表。

答案 2 :(得分：1)

要处理，请使用WebdriverWait和element_to_be_clickable并遵循xpath来单击元素。

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH,"//div[@id='NUMBER_column2_header'][contains(.,'Reference ID')]"))).click()

您需要使用以下导入来执行以上代码。

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

答案 3 :(得分：1)

要在元素上click()，必须诱使 WebDriverWait 使元素可点击，并且可以使用以下任一解决方案：

  • 使用CSS_SELECTOR：

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "th.PagingGridLayout---align_start[abbr='Reference ID'] > div.GridHeaderCell---grid_header_text"))).click()

  • 使用XPATH：

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//th[contains(@class, 'PagingGridLayout---align_start') and @abbr='Reference ID']/div[@class='GridHeaderCell---grid_header_text']"))).click()

  • 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
