我正在使用 Twitter APIv1.1，目前我正在尝试实现一个显示我最新推文的框。这可以在这里看到：
http://www.jdiadt.com/twitterv1_1feed/testindex.html
但是，我想这样做，以便当我发推文时，该框会自动更新。我对 JQuery 和 Javascript 还是很陌生，所以如果我能提供任何关于如何做到这一点的建议，我将不胜感激。我听说 AJAX 可以用于这样的事情。目前我必须刷新整个页面才能显示任何新推文。我只想刷新盒子。
这是我的脚本：twitterfeed.js
$(document).ready(function () {
var displaylimit = 10;
var twitterprofile = "jackcoldrick";
var screenname = "Jack Coldrick";
var showdirecttweets = false;
var showretweets = true;
var showtweetlinks = true;
var showprofilepic = true;
var headerHTML = '';
var loadingHTML = '';
headerHTML += '<a href="https://twitter.com/" ><img src="http://www.jdiadt.com/twitterv1_1feed/twitteroauth/images/birdlight.png" width="34" style="float:left;padding:3px 12px 0px 6px" alt="twitter bird" /></a>';
headerHTML += '<h1>'+screenname+' <span style="font-size:13px"><a href="https://twitter.com/'+twitterprofile+'" >@'+twitterprofile+'</a></span></h1>';
loadingHTML += '<div id="loading-container"><img src="http://www.jdiadt.com/twitterv1_1feed/twitteroauth/images/ajax-loader.gif" width="32" height="32" alt="tweet loader" /></div>';
$('#twitter-feed').html(headerHTML + loadingHTML);
$.getJSON('http://www.jdiadt.com/twitterv1_1feed/get_tweets.php',
function(feeds) {
//alert(feeds);
var feedHTML = '';
var displayCounter = 1;
for (var i=0; i<feeds.length; i++) {
var tweetscreenname = feeds[i].user.name;
var tweetusername = feeds[i].user.screen_name;
var profileimage = feeds[i].user.profile_image_url_https;
var status = feeds[i].text;
var isaretweet = false;
var isdirect = false;

//If the tweet has been retweeted, get the profile pic of the tweeter

isaretweet = true;

这是get_tweets.php我将结果编码为 JSON 格式的脚本。
<?php
session_start();
require_once('twitteroauth/twitteroauth/twitteroauth.php');
$twitteruser = "jackcoldrick";
$notweets = 30;
$consumerkey="xxxxxxxxxxxxxx";
$consumersecret="xxxxxxxxxxxxxxx";
$accesstoken="xxxxxxxxx";
$accesstokensecret="xxxxxxxxxxxxxx";
function getConnectionWithAccessToken($cons_key, $cons_secret, $oauth_token, $oauth_token_secret){
$connection = new TwitterOAuth($cons_key, $cons_secret, $oauth_token, $oauth_token_secret);
return $connection;
}
$connection = getConnectionWithAccessToken($consumerkey, $consumersecret, $accesstoken, $accesstokensecret);
$tweets = $connection->get("https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=".$twitteruser."&count=".$notweets);
echo json_encode($tweets);
?>
