selenium - 无法使用 Python 和 Selenium 自动点击

问题描述

我正在尝试自动将需求添加到 TestLink 数据库。我在尝试单击此锚点/跨度时遇到问题。 

<a hidefocus="on" class="x-tree-node-anchor" href="javascript:REQ_SPEC_MGMT(17473)" tabindex="1">
<span unselectable="on" id="extdd-6">0:Project-0 (0)</span>
</a>

这是我尝试过的 Python 代码部分：

anchor = browser.find_element_by_xpath('//a[contains(@href, "REQ_SPEC_MGMT")]')
span = anchor.find_element_by_xpath('.//span')

anchor.click()  # Doesn't work
span.click()    # Doesn't work
browser.execute_script("arguments[0].click();", anchor)  # Doesn't work
browser.execute_script("arguments[0].click();", span)    # Doesn't work

我没有收到任何错误，但是当我手动单击链接时仍然没有看到出现的页面。我通过转储属性验证了我找到了正确的锚点/跨度，所以我知道我有正确的元素。我也尝试过长时间的停顿，以确保在我尝试之前该元素是可点击的。关于我做错了什么的任何想法？谢谢！

更新 - 这是 HTML 的较大部分：

<div id="tree_div" style="overflow:auto; height:100%;border:1px solid #c3daf9;" class=" x-panel x-tree">

解决方案

首先，尝试使用隐式硒等待，以确保所有元素都已下载。

anchor = WebDriverWait(browser,30).until(EC.element_to_be_clickable((By.XPATH, '//a[contains(@href, "REQ_SPEC_MGMT")]')))
span = WebDriverWait(anchor,30).until(EC.element_to_be_clickable((By.XPATH, './/span')))

如果它不能正常工作，请尝试在 href 中执行 js 脚本：

browser.execute_script("javascript:REQ_SPEC_MGMT(17473)")

或者

browser.execute_script(anchor.get_attribute("href"))
