jQuery，JSON，Flickr API

$.ajax({ url: "http://api.flickr.com/services/rest/?method=flickr.photos.getSizes&format=json&api_key=708f179518b2093d23f0aef284b565a4&photo_id=6115633659&jsoncallback=?", type: "GET", cache: true, dataType:'jsonp', success: function (data) { var largeSRC = data.sizes.size.Original; alert(largeSRC); } }); 

所以，是的，基本上，我不知道如何…我甚至不知道如何称呼它。 我想获取原始大小的URL。 http://www.flickr.com/services/api/explore/flickr.photos.getSizes

 jsonFlickrApi({ "sizes": { "canblog": 0, "canprint": 0, "candownload": 1, "size": [ { "label": "Square", "width": 75, "height": 75, "source": "http:\/\/farm7.static.flickr.com\/6068\/6115633659_500f8bbd74_s.jpg", "url": "http:\/\/www.flickr.com\/photos\/b34u_h4r13y_n47h4n_7h0m45\/6115633659\/sizes\/sq\/", "media": "photo" }, { "label": "Thumbnail", "width": 100, "height": 66, "source": "http:\/\/farm7.static.flickr.com\/6068\/6115633659_500f8bbd74_t.jpg", "url": "http:\/\/www.flickr.com\/photos\/b34u_h4r13y_n47h4n_7h0m45\/6115633659\/sizes\/t\/", "media": "photo" }, { "label": "Small", "width": "240", "height": "159", "source": "http:\/\/farm7.static.flickr.com\/6068\/6115633659_500f8bbd74_m.jpg", "url": "http:\/\/www.flickr.com\/photos\/b34u_h4r13y_n47h4n_7h0m45\/6115633659\/sizes\/s\/", "media": "photo" }, { "label": "Medium", "width": "500", "height": "331", "source": "http:\/\/farm7.static.flickr.com\/6068\/6115633659_500f8bbd74.jpg", "url": "http:\/\/www.flickr.com\/photos\/b34u_h4r13y_n47h4n_7h0m45\/6115633659\/sizes\/m\/", "media": "photo" }, { "label": "Medium 640", "width": "640", "height": "424", "source": "http:\/\/farm7.static.flickr.com\/6068\/6115633659_500f8bbd74_z.jpg", "url": "http:\/\/www.flickr.com\/photos\/b34u_h4r13y_n47h4n_7h0m45\/6115633659\/sizes\/z\/", "media": "photo" }, { "label": "Large", "width": "1024", "height": "678", "source": "http:\/\/farm7.static.flickr.com\/6068\/6115633659_500f8bbd74_b.jpg", "url": "http:\/\/www.flickr.com\/photos\/b34u_h4r13y_n47h4n_7h0m45\/6115633659\/sizes\/l\/", "media": "photo" }, { "label": "Original", "width": "1440", "height": "954", "source": "http:\/\/farm7.static.flickr.com\/6068\/6115633659_cdaca906e1_o.jpg", "url": "http:\/\/www.flickr.com\/photos\/b34u_h4r13y_n47h4n_7h0m45\/6115633659\/sizes\/o\/", "media": "photo" } ] }, "stat": "ok" }) 

请帮我摆脱这个可怕的猜谜游戏。

谢谢。

Answer 1

使用

 $.ajax({ url: "http://api.flickr.com/services/rest/?method=flickr.photos.getSizes&format=json&api_key=708f179518b2093d23f0aef284b565a4&photo_id=6115633659&jsoncallback=?", type: "GET", cache: true, dataType: 'jsonp', success: function(data) { var sizelist = data.sizes.size; for (var i = 0; i < sizelist.length; i++) { if (sizelist[i].label == 'Original') largeSRC = sizelist[i].source; } alert(largeSRC); } }); 

演示http://jsfiddle.net/NGr23/

问题是size是一个数组。 因此，您需要迭代其元素以找到label为“原始”的元素。

试试这个http://jsfiddle.net/genesis/TyDHK/5/

  $.ajax({ url: "http://api.flickr.com/services/rest/?method=flickr.photos.getSizes&format=json&api_key=708f179518b2093d23f0aef284b565a4&photo_id=6115633659&jsoncallback=?", type: "GET", cache: true, dataType: 'jsonp', success: function(data) { var largeSRC = data.sizes.size[6].width + ' ' + data.sizes.size[6].height ; alert(largeSRC); } });

试试这个。

 var url = "http://api.flickr.com/services/rest/?method=flickr.photos.getSizes&format=json&api_key=708f179518b2093d23f0aef284b565a4&photo_id=6115633659&jsoncallback=?"; var largeSRC = ""; $.getJSON(url, function(data) { $.each(data.sizes.size, function(i, datum) { $.each(datum, function(key, value) { if (key === "label" && value === "Original") { largeSRC = datum.source; alert(largeSRC); } }); }); });
