無法使用Python和Selenium自動執行點擊

Question

我正在嘗試自動將需求添加到TestLink數據庫。 我在嘗試點擊此錨點/跨度時遇到問題。

<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>

這是我嘗試過的事情的Python代碼部分：

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

我沒有收到任何錯誤，但是仍然沒有得到手動單擊鏈接時出現的頁面。 我驗證了通過轉儲屬性找到正確的錨點/跨度，因此我知道我具有正確的元素。 我還嘗試了長時間的停頓，只是為了確保在嘗試之前可以單擊該元素。 關於我在做什么錯的任何想法嗎？ 謝謝！

更新-這是HTML的較大部分：

<div id="tree_div" style="overflow:auto; height:100%;border:1px solid #c3daf9;" class=" x-panel x-tree">
<div class="x-panel-bwrap" id="ext-gen12"><div class="x-panel-body x-panel-body-noheader" id="ext-gen13" style="overflow: auto;">
<ul class="x-tree-root-ct x-tree-arrows" id="ext-gen14">
<li class="x-tree-node"><div ext:tree-node-id="17472" class="x-tree-node-el x-unselectable x-tree-node-expanded" unselectable="on" id="extdd-1">

Answer 1

首先，嘗試使用隱式硒等待，以確保所有元素都已下載。

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')))

如果工作不正常，請嘗試在href中執行js腳本：

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

要么

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

Answer 2

我發現了問題。 我傳遞給execute_script的某些字符已被我的vnc軟件刪除（ Python Selenium腳本會刪除鍵，但僅在VNC上使用時才刪除 ）。

Answer 3

要在文本為0的元素上click() ：Project-0（0）元素是啟用了JavaScript的元素，因此要在該元素上click() ，必須為element_to_be_clickable()誘導WebDriverWait ，並且可以使用以下任一方法解決方案：

• 使用CSS_SELECTOR ：

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "ax-tree-node-anchor[href*='REQ_SPEC_MGMT']>span[id^='extdd-']"))).click() 

• 使用XPATH ：

   WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[@class='x-tree-node-anchor' and contains(@href, 'REQ_SPEC_MGMT')]/span[starts-with(@id, 'extdd-') and text()='0:Project-0 (0)']"))).click() 

• 注意 ：您必須添加以下導入：

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