json遍历对象
arr= [
{"name":"wyy", "password":"1111"},
{"name":"tay", "password":"2222"}
];
for(var p in arr){//遍历json数组时，这么写p为索引，0,1
alert(arr[p].name + " " + arr[p].password); // wyy 111 //tay 222
}
arr = {"name":"wyy", "xuehao":"4735"};
for(var p in myJson){ //遍历json对象的每个key/value对,p为key
console.log(p + " " + arr[p]); // name wyy
//xuehao 4735
} //aleat()显示带有一条消息和ok按钮的警告框
遍历键和值
arr = {"name":"wyy", "xuehao":"4735"};
for(var p in myJson){ //遍历json对象的每个key/value对,p为key
alert(p + " " + arr[p]); // name wyy
//xuehao 4735
}
