从下拉列表中选择文本（选择框）

Question

这是我的选择代码。我想提醒标签的价值：＆＃39; subalertTypeDesc＆＃39;。 我怎么能用jquery / js做到这一点？

＆＃13;

＆＃13;

UIStoryboard  *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"RoloBusinessCard"];
[self.navigationController pushViewController:vc animated:YES];

＆＃13;

＆＃13;

＆＃13;

将以下代码添加到您的页面

<script> 
    $("#portfolioSubTypes").change(function(){
       var txt =  $("#portfolioSubTypes option:selected").text();
       alert(txt);
    });

</script>
