如何循环浏览JSON对象
这个问题在这里已经有了答案：
您可以使用.forEach遍历数组，然后在前一个循环内使用for in循环遍历属性。
var data = {"status":200,"status_message":"Valid Account","AircraftList":[{"ID":"1","FullTXT":"Boeing 777-200ER","TypeCode":"772","Manufacturer":"Boeing","Model":"777","Variant":"200ER","PaxCnt":"305","RangeNM":"5240","MinRwFT":"8000","Cost":"261500000","DeliveryDelay":"18"},{"ID":"2","FullTXT":"Airbus A320-200","TypeCode":"320","Manufacturer":"Airbus","Model":"A320","Variant":"200","PaxCnt":"186","RangeNM":"3300","MinRwFT":"2100","Cost":"98000000","DeliveryDelay":"9"}]}
var MyAircraftList = data.AircraftList;
MyAircraftList.forEach(function(aircraft, i) {
for (var key in aircraft) {
console.log(i, key, aircraft[key]);
}
});我会使用一个简单的递归函数遍历一个对象。 它可以通过嵌套对象进行迭代。
// Your response
var response = {
"status": 200,
"status_message": "Valid Account",
"AircraftList": [{
"ID": "1",
"FullTXT": "Boeing 777-200ER",
"TypeCode": "772",
"Manufacturer": "Boeing",
"Model": "777",
"Variant": "200ER",
"PaxCnt": "305",
"RangeNM": "5240",
"MinRwFT": "8000",
"Cost": "261500000",
"DeliveryDelay": "18"
}, {
"ID": "2",
"FullTXT": "Airbus A320-200",
"TypeCode": "320",
"Manufacturer": "Airbus",
"Model": "A320",
"Variant": "200",
"PaxCnt": "186",
"RangeNM": "3300",
"MinRwFT": "2100",
"Cost": "98000000",
"DeliveryDelay": "9"
}]
};
定义这个函数的某个地方：
function iterateRecursively(object, callbackFunction) {
// Walk through object
for (var keyName in object) {
// If the given parameter is an object, call the function over and
// over again, till you get a string or number
if (typeof object[keyName] === 'object') {
iterateRecursively(object[keyName], callbackFunction);
} else {
// Callback function to do something with results outside of main function
if (typeof callbackFunction === 'function') {
callbackFunction(keyName, object[keyName]);
}
}
}
}
所以，现在你可以通过使用以下代码遍历子元素：
iterateRecursively(response.AircraftList, function (key, value) {
// You could use "status" as condition. For example if you get some other status
// than "200", you could do something else (may be an error message).
// For example:
// if(key == 'status' && value != 200) doSomething();
console.log(key + " = " + value);
});
您也可以将整个“响应”对象传递给函数。 它会有同样的效果。 此外，您还可以访问“status_message”等其他元素
