改变背景颜色并使用jquery提醒它

Question

我开始学习jquery,我试图改变背景颜色并用回调警告它,它不起作用可能在我的语法中缺少了...

$("#b").click(function(){
  $("body").css("background-color,yellow",function(){
     alert("background-color has changed successfully");
  });
});

在此先感谢您的帮助!:)

Answer 1

 $("#b").click(function(e){
  $("body").css("background-color","yellow");
  alert("background-color has changed successfully");
  e.preventDefault();
 });

你错过了"内部css的'背景颜色'属性.
