Hi, I used the code below for a function that I have to repeat with the same
code. Samething like the stars in gmail for example that with one click I
sign a message, with the second I sign-off the message.
My code work perfect with Firefox but with Mozilla it work only the first
time that I click the command. I hope my question clear. Sorry for bad
English and thanks for your answers. Stefano.
Ho usato il codiceseguente che sotto mozilla funziona bene, sotto IE mi
funziona solo la prima volta, dalla seconda in poi mi ripete la stessa
cosa...cosa devo cambiare?grazie.
var http_request = false;
function makeRequest(url) {
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
http_request.onreadystatechange = alertContents;
http_request.open('GET', url, true);
http_request.send(null);
}
function alertContents() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
alert(http_request.responseText);
} else {
alert('There was a problem with the request.');
}
}
} 8 1270

open() resets all event listeners. Switch the order of the last two
statements.

Sorry, but your English version was misleading. The googled Italian one
says:
"under IE me works only before the time, from the second one in then me
repeats the same thing"
Now it's clear: you need either disable caching by setting response
header or you need to randomize your URL.
Quick'n'dirty (presuming your URL already contains some search part
like ...?foo=bar):
// this line is added:
url+= '&rnd=' + (new Date()).getTime();
http_request.open('GET', url, true);

I solved my problem changing GET with POST!

Since you did not post how this code is called, one can only make an
educated guess, if that. Maybe you are using some `href="javascript :'
code. See the FAQ about it:

It only works now (if it really works) because POST requests are not cached
in _your_ environment. Using some kind of cache control as suggested (where
the above suggestion is not the best approach to this) is the reasonable
course of action.

I called the code with:
echo "<a href=\"#\"
onclick=\"makeRequest('tick.php?tick=prima&id=$res ult[id]')\"><img
src=\"img/tick.gif\" border=\"0\" alt=\"Add\"></a>";
with php sintax.

When posting to a javascript newsgroup, it's best to post the souce of the
page after it has been delivered to the browser.
Your code above surely results in this:
<a href="#" onclick="makeRequest('tick.php?tick=prima&id=$resu lt[id]')"><img
src="img/tick.gif" border="0" alt="Add"></a>
which would explain the problem. There is no 'return false' in your onClick
handler, so the browser then goes to your href="#".
See http://www.JavascriptToolbox.com/bestpractices/ for information about
correctly triggering javascript actions from anchor tags.
