<script type="text/javascript" src="./js/jquery-2.1.4.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var array=[
{name:'Naver',link:'http://www.naver.com'},
{name:'Daum',link:'http://www.daum.net'},
{name:'google',link:'http://www.google.com'}
];
//for
for(var i=0;i<array.length;i++){
console.log(array[i].name+'/'+array[i].link);
}
for(var i in array){
console.log(array[i].name+'/'+array[i].link);
}
});
</script>
