很久以前我使用JSON并成功获得来自twitter和facebook的哈希标签供稿。但是目前我只能获得提要,但它不会不断更新,这意味着它没有动态更新。我想我需要ajaxify它,但我不能这样做,因为我不知道ajax。这是我用来获取Twitter搜索提要的代码。
$(document).ready(function()
{
$("#Enter").click(function(event){
var searchTerm = $("#search").val() ;
var baseUrl = "http://search.twitter.com/search.json?q=%23";
$.getJSON(baseUrl + searchTerm + "&rpp=1500&callback=?", function(data)
{
$("#tweets").empty();
if(data.results.length < 1)
$('#tweets').html("No results JOINEVENTUS");
$.each(data.results, function()
{
$('<div align="justify"></div>')
.hide()
.append('<hr> <img src="' + this.profile_image_url + '" width="40px" /> ')
.append('<span><a href="http://www.twitter.com/'
+ this.from_user + '">' + this.from_user
+ '</a> ' + makeLink(this.text) + '</span>')
.appendTo('#tweets')
.fadeIn(800);
});
});
});
});
function makeLink(text)
var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
return text.replace(exp,"<a href='$1'>$1</a>");
}

以下代码可以为您提供帮助。我所做的是将获取推文的代码移动到一个函数中。然后每隔X秒调用此函数以更新该框。当用户输入新的搜索词并单击“Enter”时,它将重置计时器。
var fetchSeconds = 30; //Number of seconds between each update
var timeout; //The variable which holds the timeout
$(document).ready(function() {
$("#Enter").click(function(event){
//Clear old timeout
clearTimeout(timeout);
//Fetch initial tweets
fetchTweets();
});
});
function fetchTweets() {
//Setup to fetch every X seconds
timeout = setTimeout('fetchTweets()',(fetchSeconds * 1000));
var searchTerm = $("#search").val();
var baseUrl = "http://search.twitter.com/search.json?q=%23";
$.getJSON(baseUrl + searchTerm + "&rpp=1500&callback=?", function(data) {
$("#tweets").empty();
if (data.results.length < 1) {
$('#tweets').html("No results JOINEVENTUS");
}
$.each(data.results, function() {
$('<div align="justify"></div>').hide()
.append('<hr> <img src="' + this.profile_image_url + '" width="40px" /> ')
.append('<span><a href="http://www.twitter.com/'+ this.from_user + '">' + this.from_user + '</a> ' + makeLink(this.text) + '</span>')
.appendTo('#tweets')
.fadeIn(800);
});
});
}
function makeLink(text) {
var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
return text.replace(exp,"<a href='$1'>$1</a>");
}
希望这有帮助
