selenium - 从隐藏的下拉菜单中选择选项

Question

<table id="rusTable" class="groupTable" cellspacing="0" cellpadding="0">
  <tbody class="ui-sortable" style="">
    <tr class="groupTop ruBorder" style="display: table-row;">
    <tr id="ru0" class="siru">
    <tr class="ruOp off">
      <td class="first"></td>
      <td colspan="3">
        <select class="ruOpSelect">
          <option></option>
          <option value="AND">AND</option>
          <option>AND NOT</option>
          <option>OR</option>
        </select>  
      </td>
      <td class="last"></td>
    </tr>
    <tr id="ru1" class="siru">
    <tr class="ruOp off">
      <td class="first"></td>
      <td colspan="3">
      <td class="last"></td>
    </tr>
    <tr id="ru2" class="siru">
    <tr class="groupBtm ruBorder" style="display: table-row;">
  </tbody>
  <tfoot>
</table>

我想选择AND选项

Selenium WebDriver代码

actions.moveToElement(driver.findElement(By.xpath("//*@id='ruTable']/tbody/tr[3]/td[2]"))).build().perform();
waitForElement(By.xpath("(//*[@id='ruTable']//*[contains(@class,'ruOpSelect')])[1]"),30);
new Select(driver.findElement(By.xpath("(//*[@id='ruTable']//*[contains(@class,'ruOpSelect')])[1]"))).selectByVisibleText("AND");

它会进行悬停操作，但不会从下拉菜单中选择任何内容


错误-等待By.xpath定位的元素的可见性在30秒后超时：
（ //*[@id='ruTable']//*[contains(@class,'ruOpSelect')])[1]

Answer 1

尝试使用此xpath，只需单击以下命令即可：

"//select[@class='ruOpSelect']/option[text()='AND']"

通常我在 select中以“ xpath”开头的任何下拉菜单都应该是下一个选项。
