【问题描述】：

我正在使用 Selenium 进行网络自动化，但无法选择具有 onClick 属性且没有 href 和类名称的锚标记。下面是表单的源代码，我想点击第一个和第三个锚标签

<td colspan="4" class="leftTopFormLabel">
    12. Details of Nominee :<span class="mandatoryField">*</span>
</td>
<td colspan="2" class="lastFormValue">
    <a onclick="openWin('NomineeDetails.aspx','','dialogWidth:1000px; dialogHeight:800px; center:yes')"
        style="text-decoration: Dynamic; color: Blue; cursor: pointer">Enter Details Here</a>
</td>
</tr>
<tr class="lastData_Section" id="Tr12">
<td colspan="4" class="leftTopFormLabel">
    13. Family Particulars of Insured Person:
</td>
<td colspan="2" class="lastFormValue">
    <a onclick="openWin('FamilyDetails_New.aspx','','dialogWidth:1000px; dialogHeight:800px; center:yes');"
        target="_blank" style="text-decoration: Dynamic; color: Blue; cursor: pointer">Enter
        Details Here</a>
</td>
</tr>
<tr class="lastData_Section" id="Tr18">
<td colspan="4" class="leftTopFormLabel">
    14. Details of Bank Accounts of Insured Person:<span class="mandatoryField">*</span>
</td>
<td colspan="2" class="lastFormValue">
    <a onclick="openWin('EmployeeBankDetails.aspx','','dialogWidth:1000px; dialogHeight:800px; center:yes');"
        style="text-decoration: Dynamic; color: Blue; cursor: pointer">Enter Details Here</a>
</td>
</tr>

谁能推荐我？

【解决方案1】：

这应该可行。使用 contains 方法解析 onclick 属性：

//a[contains(@onclick,'NomineeDetails.aspx')]

【解决方案2】：

您的所有<a>...</a> 元素都没有href 属性。它们都没有class 属性。

这是选择具有onclick 属性但没有target 属性的对象的一种方法。

data = '''\

    print(a.attrs.keys(), a.text)
