[英]Can't push nested JSON Objects into an array
我對jQuery非常陌生,並且正在嘗試弄清楚如何將嵌套的JSON對象放入數組中。 這是JSON數據:
{
"0": {
"country": "US",
"itemId": "391296746967",
"price": "4.99",
"shippingCost": {
"expeditedShipping": "false",
"handlingTime": "1",
"oneDayShippingAvailable": "false",
"shipToLocations": "Worldwide",
"shippingServiceCost": {
"_currencyId": "USD",
"value": "0.0"
},
"shippingType": "Free"
},
"title": "Tea Infuser Ball Mesh Loose Leaf Herb Strainer Stainless Steel Secure Locking 2\"",
"user_args": {
"advanced": null,
"pages": {
"entries_per_page": 4,
"page_number": 4
},
"search_terms": "ball"
}
},
"1": {
"country": "US",
"itemId": "382548457911",
"price": "18.9",
"shippingCost": {
"expeditedShipping": "true",
"handlingTime": "1",
"oneDayShippingAvailable": "false",
"shipToLocations": "Worldwide",
"shippingServiceCost": {
"_currencyId": "USD",
"value": "0.0"
},
"shippingType": "Free"
},
"title": "Baby Kid Outdoor Indoor Princess Play Tent Playhouse Ball Pit Pool Toddler Toys",
"user_args": {
"advanced": null,
"pages": {
"entries_per_page": 4,
"page_number": 4
},
"search_terms": "ball"
}
},
"2": {
"country": "US",
"itemId": "132543955826",
"price": "13.99",
"shippingCost": {
"expeditedShipping": "false",
"handlingTime": "1",
"oneDayShippingAvailable": "false",
"shipToLocations": "Worldwide",
"shippingServiceCost": {
"_currencyId": "USD",
"value": "0.0"
},
"shippingType": "Free"
},
"title": "Yoga Ball w Air Pump Anti Burst Exercise Balance Workout Stability 55 65 75 85cm",
"user_args": {
"advanced": null,
"pages": {
"entries_per_page": 4,
"page_number": 4
},
"search_terms": "ball"
}
},
"3": {
"country": "US",
"itemId": "173659697373",
"price": "155.0",
"shippingCost": {
"expeditedShipping": "false",
"handlingTime": "0",
"oneDayShippingAvailable": "false",
"shipToLocations": "Worldwide",
"shippingServiceCost": {
"_currencyId": "USD",
"value": "0.0"
},
"shippingType": "Free"
},
"title": "DribbleUp Smart Soccer Ball with Training App Size 5 For Adults (***Buy ME***)",
"user_args": {
"advanced": null,
"pages": {
"entries_per_page": 4,
"page_number": 4
},
"search_terms": "ball"
}
}
}
從這個JSON中,我需要price
, shippingCost.value
, shippingType
和title
。 我已經搜索了實現此目標的方法,但是我發現的只是有關$ .getJSON()方法的信息,而且我不知道如何使用該方法來實現我的目標。 如果有人能指出我正確的方向,將不勝感激!
您可以使用$.getJSON
獲取JSON,然后遍歷它們的值並將其推入數組。
試試這個http://jsfiddle.net/j26bkomu/ (打開控制台)
擁有json后,您可以遍歷其鍵值對並將它們保存在數組中:
$.getJSON( "./test.json", function( data ) {
var items = [];
var objJson = {};
$.each( data, function( key, val ) {
objJson.price = val.price;
objJson.value = val.shippingCost.shippingServiceCost.value;
objJson.type = val.shippingCost.shippingType;
objJson.title = val.title;
items.push( objJson );
objJson = {};
});
console.log(items);
});
輸出:
(4) [{…}, {…}, {…}, {…}]
0:
price: "4.99"
title: "Tea Infuser Ball Mesh Loose Leaf Herb Strainer Stainless Steel Secure Locking 2""
type: "Free"
value: "0.0"
__proto__: Object
1:
price: "18.9"
title: "Baby Kid Outdoor Indoor Princess Play Tent Playhouse Ball Pit Pool Toddler Toys"
type: "Free"
value: "0.0"
__proto__: Object
2: {price: "13.99", value: "0.0", type: "Free", title: "Yoga Ball w Air Pump Anti Burst Exercise Balance Workout Stability 55 65 75 85cm"}
3: {price: "155.0", value: "0.0", type: "Free", title: "DribbleUp Smart Soccer Ball with Training App Size 5 For Adults (***Buy ME***)"}
length: 4
__proto__: Array(0)
