<span style="font-size:14px;">		/*var my=["包","包","包","包","包"];
var p=my;//my将地址复制给了p*/

var ym=[];
ym['name']="杨幂";
ym['math']=81;
ym['chs']=53;
ym['eng']=89;
console.log(ym);

var fbb=[];
fbb['name']="范冰冰";
fbb['math']=89;
fbb['chs']=65;
fbb['eng']=95;
console.log(fbb);
for(var key in ym){
console.log(key+":"+ym[key]);
}

var names=['efe','tom','jerry'];
for(var key in names){
console.log(key+":"+names[key]);
