想知道是否有人可以提供帮助;
我有基于twitter post fetcher code的代码;
它逐一显示推文，然而它的效果很好;但是一旦它达到代码中定义的最大推文数，就会显示未定义的;或者如果它到达人们必须点击加载更多的饲料点;
有没有办法让它循环？例如，如果我将max tweets设置为10，如下所示，让它循环遍历10而不是show undefined？
感谢您的帮助

/**
* ### HOW TO CREATE A VALID ID TO USE: ###
* Go to www.twitter.com and sign in as normal, go to your settings page.
* Go to "Widgets" on the left hand side.
* Create a new widget for what you need eg "user time line" or "search" etc.
* Feel free to check "exclude replies" if you don't want replies in results.
* Now go back to settings page, and then go back to widgets page and
* you should see the widget you just created. Click edit.
* Look at the URL in your web browser, you will see a long number like this:
* 345735908357048478
* Use this as your ID below instead!

/**
* How to use TwitterFetcher's fetch function:
*
* @function fetch(object) Fetches the Twitter content according to
* the parameters specified in object.
*
* @param object {Object} An object containing case sensitive key-value pairs
* of properties below.
*
* You may specify at minimum the following two required properties:
*
* @param object.id {string} The ID of the Twitter widget you wish
* to grab data from (see above for how to generate this number).
* @param object.domId {string} The ID of the DOM element you want
* to write results to.
*
* You may also specify one or more of the following optional properties
* if you desire:
*
* @param object.maxTweets [int] The maximum number of tweets you want
* to return. Must be a number between 1 and 20. Default value is 20.
* @param object.enableLinks [boolean] Set false if you don't want
* urls and hashtags to be hyperlinked.
* @param object.showUser [boolean] Set false if you don't want user
* photo / name for tweet to show.
* @param object.showTime [boolean] Set false if you don't want time of tweet
* to show.
* @param object.dateFunction [function] A function you can specify
* to format date/time of tweet however you like. This function takes
* a JavaScript date as a parameter and returns a String representation
* of that date.
* @param object.showRetweet [boolean] Set false if you don't want retweets
* to show.
* @param object.customCallback [function] A function you can specify
* to call when data are ready. It also passes data to this function
* to manipulate them yourself before outputting. If you specify
* this parameter you must output data yourself!
* @param object.showInteraction [boolean] Set false if you don't want links
* for reply, retweet and favourite to show.
* @param object.showImages [boolean] Set true if you want images from tweet
* to show.
* @param object.lang [string] The abbreviation of the language you want to use
* for Twitter phrases like "posted on" or "time ago". Default value
* is "en" (English).

// ##### Advanced example #####
// An advance example to get latest 5 posts using hashtag #API and write to a
// HTML element with id "tweets2" without showing user details and using a
// custom format to display the date/time of the post, and does not show
// retweets.
var config4 = {
"id": '638725381294551040',
"domId": 'twitterfeed',
"showUser": false,
"maxTweets": 10,
"enableLinks": true,
"customCallback": gotTweets
};
twitterFetcher.fetch(config4);
var tweets = [];
var i = 0;
function gotTweets(data){
tweets = data;
};
function showNextTweet() {
document.getElementById("twitterfeed").innerHTML = tweets[i];
i++;
console.log("Showing tweet " + (i+1));
}
setInterval(showNextTweet, 4000);<div id="twitterfeed"><br>loading tweets</div>
答案 0 :(得分：1)
我不确定你在问什么，如果你更具体，那会有所帮助。也许这就是你想要的（无论多么简单）：
function showNextTweet() {
// Reset your counter
if(i >= tweets.length) {
i = 0;
}
document.getElementById("twitterfeed").innerHTML = tweets[i];
i++;
console.log("Showing tweet " + (i+1));
}
