python - 无法使用带有 selenium 的 python3 在表中找到链接

Question

大家好，我正在使用 Python 3.0，我正在尝试点击表格中的链接。

目前找不到链接，所以无法点击。

下面是选中元素的html

这里的道歉是代码的一个更好的例子......

<div id="divMyActivities2" originalheight="125px" style="overflow-y:auto;top:0px;left:0px;width:451px;height:125px;">
        <table id="tblMyActivities" class="podborder" border="0" cellpadding="3" cellspacing="0" style="overflow-y: auto; table-layout: fixed; border: 1px solid #CCCCCC; border-top: none; width: 100%; border-top-left-radius: 0px; border-top-right-radius: 0px">

我正在尝试选择这个元素:

<label onclick="pageNav('serviceRequests');" class="tablelink">Service Tickets</label>

我尝试过的......

尝试过:

driver.find_element_by_partial_link_text('Tickets').click()

异常:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"partial link text","selector":"Tickets"

尝试过:

driver.find_element_by_link_text('Service Tickets').click()

异常:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"link text","selector":"Service Tickets"

尝试过

driver.find_elements_by_css_selector(".tablelink")

结果:

produces an empty list "[]"

尝试过:

driver.find_element_by_tag_name("label")

异常:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"tag name","selector":"label"}

我找到了这个 URL，但我无法更改代码:Find and click an item from 'onclick' partial value

• 疯狂的猜测我厌倦了从链接解码

尝试过:

driver.find_element_by_css_selector("tablelink[onclick*='Service Tickets']")

异常:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":"tablelink[onclick*='Service Tickets']"}

任何帮助都会很棒，在此先感谢。

Answer 1

Apolgos 仍在学习这一切。

我必须切换 Iframe 然后才能通过 XPATH 找到代码。

我不想一次粘贴整个代码，因为要深入研究的页面很长。

driver.switch_to_frame(driver.find_element_by_class_name("gwt-Frame"))
driver.find_element_by_xpath("//label[contains(.,'Service Tickets')]").click()

感谢您的宝贵时间。
