Question

我在WebDriver中从下拉列表中选择一个选项时出现问题，其中选项为type=radio，如下所示：

<input id="ui-multiselect-companyListSelect-option-2" type="radio" title=" Display Deleted " value="deleted" name="multiselect_companyListSelect" aria-selected="true">
<span> Display Deleted </span>

我正在使用以下XPath表达式：

selectDisplayDeleted = //input[@name='multiselect_companyListSelect']/../span[text()=' Display Deleted '] and executing selectDisplayDeleted.click() on this element.

我收到以下异常：

Answer 1

尝试两次点击。首先是下拉列表，然后是选项值。根据您提供的xpath，第一次单击将在元素输入[@ name ='multiselect_companyListSelect']上，然后是选项值。

Answer 2

嗯，你的XPath对我来说有点过于宽松，使用following-sibling或preceding-sibling轴来获取span可能会更好。你的跨度文本中似乎还有一些可能导致问题的空白？

//span[contains(text(), 'Display Deleted'][preceding-sibling::input/@name eq 'multiselect_companyListSelect']

无法使用WebDriver单击每个选项为单选按钮的下拉菜单
