jQuery，JSON，Flickr API

Question

$.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......我甚至不知道如何定義它。我正在嘗試獲取原始大小的網址。 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" },

] }, "stat": "ok" }) 

請幫我脫離這可怕可怕的猜謎遊戲逃脫。

謝謝。

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); 

    } 
}); 

在http://jsfiddle.net/NGr23/

演示的問題是，size是一個數組。所以你需要遍歷它的元素來找到label的'Original'..

試試這個 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); 

    } 
});

試試這個。

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); 
      } 
     }); 
    }); 
});
