用jQuery遍历JSON结果

for(var key in result) {    var value = result[key];    if(typeof value == 'object') {        if(value instanceof Array) { // an array. loop through children for(var i = 0; i < value.length; i++) {     var item = value[i]; }        } else { // complex object, not array. inner for loop on keys?        }    } else {        // regular string/number etc. just print out value?    }}
