JS函数的定义与调用方法推荐

var blogInfo={　　blogId:123,　　blogName:"werwr",　　showBlog:function(){alert(this.blogId);}};blogInfo.showBlog();

var myfunc = function(a,b){　　return a+b;}alert(myfunc(3,4));

var myfunc = function(a){　　this.a = a;};myfunc.prototype = {　　show:function(){alert(this.a);}}var newfunc = new myfunc("123123123");newfunc.show();

var myobject={};var sum = function(a,b){　　return a+b;};var sum2 = sum.call(myobject,10,30); //var sum2 = sum.apply(myobject,[10,30]); alert(sum2);
