I am looking for a way to send data between two different Divs on two different pages, both are on the same domain.
This is more of a learning exercise as I am very new to jQuery and AJAX, I have been searching for a simple way of doing this but most answers or options seem to be complex and involve installing other software , etc.
I would like to have one html page listening for an event, the other html page will send an event when something happens, for example;
Page 1 - Countdown clock, every time it reaches a new hour it sends the data to Page 2
Page 2 - Listening for this data, when received it displays the data in a div
This is not exactly what I want to do in regards to the Countdown clock, it is just an example but the theory is what I need. Is it possible to set this up with just 2 flat html pages and some jQuery/AJAX code? It does not need to be secure or optimized , like I said it is just for learning.
也许您会去看一下nodejs和socket.io。这是个了不起的工具,可以通过javascript进行交互。
The simplest way is, install a server ( wamp for example), and then you can communicate between your pages, by using database or files, and then use something like that:
Page 1:
<a id="sendData">Send Data to Page 2 </a>
var url = http://localhost/yoursite/writeToFile.php
$('a#sendData').click(
$.ajax({ url: url, type: "POST", data:{test:'test'} })
.done(function() {
$(this).append(' sent!');
});
)};
Page 2:
<div>Listening to Page 1 </div>
window.setInterval(function(){
listenToPage1();
}, 5000);
function listenToPage1()
{
var url = http://localhost/yoursite/readFromFile.php
$.get(url, function(data) { $('div').html(data); });
}
writeToFile.php
<?php
$fp = fopen('data.txt', 'a');
fwrite($fp, $_POST);
fclose($fp);
?>
readFromFile.php
<?php
readfile('data.txt');
?>
yoursite folder:
www/
/yousite
readFromFile.php
writeToFile.php
page1.php
page2.php
data.txt
And of course you can use nodejs
to make interactions directly by javascript
, but I think it's better to start by learning the basics and then you can move to nodejs
(it doesn't mean nodejs
is very complicated :p)
