但是對我的生活我不能建立我的字符串，我想。我正在使用的「理論」是。

while i <= json[count]{ //open loop using json count data 
    tweet = json[items[i]][description]; //get the tweet 
    tweet = tweet.replace(/\/g,""); //remove slashes 
    by = json[items[i]][author]; //get author 
    by = by.split("("); //ignore full name just get short 
    by = by[1]; // shortname 
    by = by.replace(/)/g,""); //remove last) 
    avatar = json[items[i]][media:content][url]; //get avatar url 
    avatar = avatar.replace(/\/g, "") //remove slashes 
    tweet = "<img src=""+avatar+"" width=\"16\" height=\"16\" />"+author+": "+tweet; //format the tweet 
    $("#tweetarea").append(tweet); //print it to #tweetarea 
    i++ //update counter 
} //close loop

但老實說，我不能弄清楚這個json百靈。任何人都願意編寫jquery代碼來解析這個json。並執行我上面描述的行動？

謝謝:)

試圖以精確和整齊的格式來組織你的問題，這將幫助你得到你的答案先生... – abhijit

這是更好嗎？謝謝 – Owen

你可以使用jQuery的each()方法輕鬆具體鳴叫數據遍歷JSON和追加到#tweetarea：

$.each(json.value.items, function(i, tweet) { 
     var author = tweet.author.split('(')[1].replace(')',''); 
     var avatar = tweet['media:content'].url; 
     $('#tweetarea').append('<img src="'+avatar+'" width="16" height="16" />'+author+': '+tweet['y:title']+'<br/>'); 
});

看到一個Working demo

編輯：

您可以通過jQuery的加載JSON 10方法。這是一個updated demo。

啊，這是輝煌的謝謝，但我怎麼去加載到var json飼料然而呢？ – Owen

使用jQuery AJAX API w /設置爲JSONP。類似這樣的：

$.ajax({ 
    url: 'yahoourlhere?callback=?' 
    dataType: 'jsonp', 
}).success(function(response, status, jqxhr) { 

}).error(function(jqxhr, status, error) { 

});

你需要看看是否可以得到纏繞PIPE飼料的回調名稱。這是你將如何包裝JSON的JSONP調用PHP例子：

<?php 
    $callback = $_REQUEST['callback']; 
    echo "$callback\($json\)"; 
?>
