Question

我正在尝试使用Selenium Python自动执行网页导航。我想单击执行JavaScript代码的HTML按钮，该代码将验证按钮是否集中在onclick动作上。

在这种特定情况下，我使用Selenium选择有效对象没有问题，但是简单的element.click()似乎无效。

HTML来源：

<td width="1%">
  <!--Begin /jsp/com/tibco/wfc/ButtonUI.jsp-->
  <script language="javascript">
    var isFocus = "false";
  </script>
  <button class="button_normal" name="OK" style="width:100px" onfocus="isFocus='true'" onblur="isFocus='false'" onmouseover="this.className='button_rollover'" onmouseout="this.className='button_normal'" onmousedown="this.className='button_pressed'" onmouseup="this.className='button_rollover'"
    onclick="javascript:if(isFocus=='false'){ return false}; showProgressMeter();submitCommand(event,'com_tibco_wfc_Button_498466961', 'com_tibco_wfc_DefaultFrame_1501194824', false, false, 'null', 'o', '', false);;return false;">OK</button>
  <!--End /jsp/com/tibco/wfc/ButtonUI.jsp-->
</td>

Python / Selenium属性：

warning_ok_button = driver.find_element_by_xpath("//button[@name='OK']")
attrib = driver.execute_script('var items = {}; for (index = 0; index < arguments[0].attributes.length; ++index) { items[arguments[0].attributes[index].name] = arguments[0].attributes[index].value }; return items;',warning_ok_button)
pprint(attrib)
{'class': 'button_normal',
 'name': 'OK',
 'onblur': "isFocus='false'",
 'onclick': "javascript:if(isFocus=='false'){ return false}; "
            "showProgressMeter();submitCommand(event,'com_tibco_wfc_Button_498466961', "
            "'com_tibco_wfc_DefaultFrame_1501194824', false, false, 'null', "
            "'o', '', false);;return false;",
 'onfocus': "isFocus='true'",
 'onmousedown': "this.className='button_pressed'",
 'onmouseout': "this.className='button_normal'",
 'onmouseover': "this.className='button_rollover'",
 'onmouseup': "this.className='button_rollover'",
 'style': 'width:100px'}

warning_ok_button.click()似乎只是将按钮的类别从button_normal更改为button_rollover

Answer 1

您是否尝试过通过xpath单击<td>？

Answer 2

由于@supputuri，我得以应对这一挑战。这里的技巧是触发onfocus事件，然后触发与我的按钮元素关联的onclick事件。

driver.execute_script("arguments[0].onfocus()",warning_ok_button)
driver.execute_script("arguments[0].click()",warning_ok_button)

Python Selenium：单击带有JavaScript onFocus验证的按钮
