原生js遍历json对象
遍历json对象：
无规律：
<script>
var json = [
{dd:'SB',AA:'东东',re1:123},
{cccc:'dd',lk:'1qw'}
];
for(var i=0,l=json.length;i<l;i++){
for(var key in json[i]){
alert(key+':'+json[i][key]);
}
}
</script>
有规律：
1 2 3 4 5 6 7 8 9 10 11 12 13 | packJson = [{"name":"nikita", "password":"1111"},{"name":"tony", "password":"2222"}];for(var p in packJson){//遍历json数组时，这么写p为索引，0,1 alert(packJson[p].name + " " + packJson[p].password);} |
也可以用这个：
1 2 3 4 5 | for(var i = 0; i < packJson.length; i++){ alert(packJson[i].name + " " + packJson[i].password);} |
遍历json对象
1 2 3 4 5 6 7 | myJson = {"name":"caibaojian", "password":"1111"};for(var p in myJson){//遍历json对象的每个key/value对,p为key alert(p + " " + myJson[p]);} |
有如下 json对象：
var obj ={"name":"冯娟","password":"123456","department":"技术部","sex":"女","old":30};
遍历方法：
1 2 3 4 | for(var p in obj){str = str+obj[p]+',';return str;} |
