如何遍历下拉列表中的选项？

Question

我试图遍历下拉菜单中的选项或项目，但我不知道项目的数量，因为每次都会更改。

这是sList3的html部分

<select name="ctl00$ContentPlaceHolder1$Dschool" onchange="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$Dschool\',\'\')', 0)" id="ContentPlaceHolder1_Dschool" style="font-size:12pt;font-weight:bold;width:500px;">
	<option selected="selected" value="0"> Select From Menu </option>
	<option value="311223">first option</option>
	<option value="311625">some option</option>
</select>

这是我已经开始的代码

For i = 1 To 4
    Set sList1 = .FindElementById("ContentPlaceHolder1_Dedara").AsSelect
    sList1.SelectByIndex i
    .Wait 2000
    Set sList2 = .FindElementById("ContentPlaceHolder1_Drel").AsSelect
    sList2.SelectByIndex 1
    .Wait 2000
    Set sList3 = .FindElementById("ContentPlaceHolder1_Dschool").AsSelect

    'How can I loop through the options (unknown in length)
Next i

我想循环每个选项并进行调试。打印选项的值。

解决方案

在JeffC的帮助下，这是最终的解决方案

            For j = 1 To sList3.Options.Count
            Debug.Print sList3.Options(j).Text
        Next j

Answer 1

我认为您可以为每个循环使用

WebElement selectElement = driver.findElement(By.xpath("//select[@id='ContentPlaceHolder1_Dschool']"));
Select select = new Select(selectElement);
List<WebElement> options = select.getOptions();
for (WebElement we : options) 
{
  System.out.println("Element="+we.getText());
}

Answer 2

您可以使用CSS选择器来获取父ID下的选项集合

Dim elements As Object, element As Object
Set elements = driver.FindElementsByCss("#ContentPlaceHolder1_Dschool option")

然后循环

For Each element In elements:
    Debug.Print element.text
Next

CSS：

如果id为动态，则将CSS切换为

[id^=ContentPlaceHolder1] option
