是否有一个jQuery函数来"快捷"if/else开关？

$(document).ready(function(){
  $("#toggle-button").click(function(){
    $("#hidden-div").toggle();
  });
});

$(document).ready(function(){
  var currentState = "hidden";

  $("#toggle-button").click(function(){
    if (currentState == "hidden") {
      $("#hidden-div").show();
      currentState = "shown";
    } else {
      $("#hidden-div").hide();
      currentState = "hidden";
    }
  });

  $("#state-label").click(function(){
    $("#toggle-button").text($(this).text());
    currentState = $(this).text();
  });
});
