使用jQuery訪問json值

-1

我想從twitter api中檢索的json數組中檢索趨勢值。我需要前5名的趨勢名稱。使用jQuery訪問json值

JSON響應

    "locations": [ 
     { 
      "name": "Worldwide", 
      "woeid": 1 
     } 
    ] 
}]

jQuery代碼

$.getJSON("url",function(data){ 
    console.log(data); 
});

我怎樣才能從成功函數的對象檢索值？

看來你甚至沒有嘗試使用谷歌搜索如何訪問任何類型的JSON數據。 – Jimbo

twitter API發送一個包含趨勢數據的對象。

因此，要獲得每個趨勢名字它會像下面：

for(var i = 0; i < data[0].trends.length; i++) { 
    console.log(data[0].trends[i].name); 
}

這將記錄所有趨勢的名字了。希望這有助於

謝謝你！正是我在找什麼。 –

很高興我能幫到你 –

var topTrends = []; 
foreach(var i in data[0].trends) { 
    var dat = data[0].trends[i].name; 
    topTrends.push(dat); 
    if(topTrends.length == 5) { 
     return topTrends; 
    } 
}

這將有助於你的原因

var names ='';

爲（VAR I = 0;我<數據[0] .trends.length;我++）{

if(i < 5){ 

     alert(data[0].trends[i].name); 

     names += "| +"data[0].trends[i].name""; 
}

}

names = names.substr（1）;
