我想遍历一个二维的 json 对象......对于一个一维的 json 对象，我这样做
for (key in data) {
alert(data[key]);
}
what do i do about a two dimensional one??
我该怎么办一个二维的？？

There is no two dimensional data in Javascript, so what you have is nested objects, or a jagged array (array of arrays), or a combination (object with array properties, or array of objects). Just loop through the sub-items:
Javascript 中没有二维数据，因此您拥有的是嵌套对象，或锯齿状数组（数组数组），或组合（具有数组属性的对象，或对象数组）。只需循环遍历子项：
for (var key in data) {
var item = data[key];
for (var key2 in item) {
alert(item[key2]);
}
}

perhaps you want
也许你想要
for(var i in data){
for(var j in data[i]){
alert(data[i][j]);
}
}

Try:
尝试：
for (var key in data) {
for (var key2 in data[key]){
alert(data[key][key2]);
}
}
