python - 可扩展元素通过单击自行关闭

Question

我有一个 div，它有一个 even listener 与之链接。 div 通过单击展开并显示更多按钮。我试图通过单击打开 div，然后单击暴露的按钮。但是当我执行测试时，div 被点击，展开以显示其他按钮，然后自行折叠。但是，如果手动操作，它只会在单击两次后崩溃。因此，当我尝试单击暴露的按钮时，找不到它，我得到:以下错误可互换。

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element

或

Element is not clickable at point . Other element would receive the click

我想附加的事件监听器可能通过加载太快/太慢而在其中发挥作用。看起来其他元素与目标元素重叠。如何单击目标按钮。

我试过在单击 div 和目标按钮之间给它一个 2 秒的休眠时间，但似乎只要单击 div 元素，它就会同时展开和折叠。我可以看到它这样做。我也尝试使用下面的代码: driver.execute_script("arguments[0].click();", element)

这是 html 代码片段:

   <div class="software-package-top" id="package2_toggle">

     <div class="software-package-info">
       <div class="software-package-name">
     name      </div>
       <div class="software-package-version">
         &nbsp;3.0.1      </div>
       <div class="software-package-status">
                 <span class="software-package-enabled">Disabled</span>&nbsp;&nbsp;<span class="software-package-not-running">Not Running</span>              </div>
     </div>
         <div class="software-package-arrow"></div>
       </div>
     <div class="software-package-details software-hidden" id="package2_controls" style="display: none;">
   <div class="software-package-description">
 </div>

 <hr>
 <div class="software-package-controls">
 <input type="button" name="View Release Notes" value="View Release Notes" id="package2_viewReleaseNotes" data-package="releaseNotes">
 <input type="button" name="View Runtime Log" value="View Runtime Log" id="package2_viewLog">
     <script>
 $(document).ready(function() {
       $("#package2_viewLog").click(function() {viewLog("---", "---", "no")});
 });
   </script>


   <script>
 $(document).ready(function() {
   $("#package2_enable").click(function() {appControl("---", "---", "enable",  "no")});
 });
   </script>
     <input type="button" name="Enable" value="Enable" id="package2_enable">



 <input type="button" name="Uninstall" value="Uninstall" id="package2_uninstall">
 <script>
 $(document).ready(function() {
   $("#package2_uninstall").click(function() {appControl("---", "---", "uninstall", "no")});
 });
 </script>

   </div>
 </div>
 </div>

所有这些错误信息...

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element

和

Element is not clickable at point . Other element would receive the click

...意味着您甚至在 JavaScript 之前调用了 click()或 AJAX 调用完全呈现元素和完整的 DOM Tree .

解决方案

您需要为所需的 element_to_be_clickable() 引入 WebDriverWait，如下所示:

WebDriverWait(driver, 20).until( EC.element_to_be_clickable((By.XPATH, element_xpath))).click()
