<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]);
