尝试这个：

# will select item with label 9
$dropdown = $ie.Document.getElementById("skuAndSize")
($dropdown | where {$_.innerHTML -eq "9"}).Selected = $true

找到了一个更好的解决方案，它将选择具有精确文本的值

定义一个函数

applicationList 是选择标签的id

测试 abc 是要匹配的确切文本

function Subscription()
{
$x = $IE.document.getElementById("applicationList");
for($i=0;$i -lt $x.length;$i++)
{
If($x.options[$i].text -eq "test abc")
{
return $i;
}}}

调用函数

$index=Subscription;
$IE.Document.getElementById("applicationList").SelectedIndex=$index;
