Question

我有两个bootstrap选择菜单。我想要一个div可见，只有当其中一个打开时才显示帮助信息。我的代码可以正常选择菜单但不是引导选择菜单。当你关闭一个div时，而不是当你打开一个div时，会出现div。有人可以帮忙吗？

$(document).ready(function() {
	$(".pickerSelectClass").selectpicker();   

var open = false;
      function isOpen(){
          if(open)
             $('#hidden').show();
          else
             $('#hidden').hide();
      }
      $("button").on("click", function() {
            open = !open;
            isOpen();
      });
      $("button").on("blur", function() {
            if(open){
               open = !open;
               isOpen();
            }
      });
      $(document).keyup(function(e) {
          if (e.keyCode == 27) {
            if(open){
               open = !open;
               console.log(isOpen());
      }}});
      
});
