functionMyObject(name,message){this.name=name.toString();this.message=message.toString();}MyObject.prototype={getName:function(){returnthis.name;},getMessage:function(){returnthis.message;}};和functionMyObject(name,message){this.name=name.toString();this.message=message.toString();}MyObject.prototype.getName=function(){returnthis.name;};MyObject.prototype.getMessage=function(){returnthis.message;};代碼中的下面2段有什么區(qū)別？哪種寫法比較好一些？MyObject.prototype={getName:function(){returnthis.name;},getMessage:function(){returnthis.message;}};和MyObject.prototype.getName=function(){returnthis.name;};MyObject.prototype.getMessage=function(){returnthis.message;};各位麻煩幫我解答下，不是很懂..謝謝
