JavaScript - New To Ajax, Need Suggestion.
I am very new to web development and I need a push in the right direction here. This is my problem; I am making a web page that will be used privately by two people. I need to find a way to go to an FTP site that can only be accessed by web browser (that is what IT told me) and download a file that has a constant name "prevhour.log" and save this file to a directory so that it can be read (not sure how, my boss is doing that end) and the data will be dumped, and this data will be extrapolated into a gas gauge style dashboard. I need some way of this to be done as automated as possible. Thank you for your time.
Rick Similar TutorialsHi, I have this code to get hints (PHP file): Code: <?php
include("include/session.php");
$GetNames = "SELECT firstname, lastname, username FROM users";
$GetNamesConnect = $database->query($GetNames);
While($row = mysql_fetch_array($GetNamesConnect))
{
$a[$row['username']] = $row['firstname'] . " " . $row['lastname'];
}
//get the q parameter from URL
$q=$_GET["q"];
//lookup all hints from array if length of q>0
if (strlen($q) > 0)
{
$hint="";
for($i=0; $i<count($a); $i++)
{
if (strtolower($q)==strtolower(substr($a[$i],0,strlen($q))))
{
if ($hint=="")
{
$hint=$a[$i];
}
else
{
$hint=$hint.", ".$a[$i];
}
}
}
}
// Set output to "no suggestion" if no hint were found
// or to the correct values
if ($hint == "")
{
$response="no suggestion";
}
else
{
$id = $row['username'];
$response= "<a href='profile.php?user=$row['username']'>$hint</a>";
}
//output the response
echo $response;
?>

Now, the project is still in the stage of planning. But I am quite confuse now which programming language to implement. I am going to design a system where the normal users will update the data with the system while the data required changes will need system administrator to apporve it. I will need a database to keep those records (the data required update) so that the system admin can refer to the database and make changes. Do I have another choice instead of using Microsoft Access 2007 macros or VBA ? I prefer a web-based programming. Any suggestion, please ? Hello, I am creating a little script that allows me to scroll my content sections in and out though Ajax and CSS. I have have successfully made it slide in from the top but I have one problem, sliding out! I wrote a clip for 'aniOut' that works also but I cant seem to make one load before the other in transition. I am not very good with javas cript anyone have any suggestions? So far this only is working for Chrome. My site is live with the working slide in at The Mind Company. Also I am having a load issue with some browsers and computers where the page must be refreshed in order to view proper, any suggestions? CSS: Code: header {

Hello, I have a specific need in javascript. Can I be guided in this context if its possible or not??? I am using virtuemart extension in joomla to make an ecommerce website. I will try to explain my requirement with the example. Following is the sample category tree with number. 1.0 .....1.1 ..........1.1.1 ..........1.1.2 .....1.2 ..........1.2.1 ..........1.2.2 .....1.3 ..........1.3.1 ..........1.3.2 2.0 .....2.1 ..........2.1.1 ..........2.1.2 .....2.2 ..........2.2.1 ..........2.2.2 .....2.3 ..........2.3.1 ..........2.3.2 Now I have a drop down main menu as 1.0 and 2.0. I want that when i click on 1.0 all the nodes of 1.0 should be opened and 2.0 should be closed and similarly when i click on 2.0 all its child nodes should be opened and 1.0 should be closed. What happen with most extensions is that at a time only one child is opened. If i click on 1.0 then only 1.1 or 1.2 or 1.3 will remain open at a time. Does this kind of customization can be done or is available in javascript .... I hope i will be helped... Thanks a lot for the time. I've been using Coffeecup free version for HTML/CSS needs and it works fine as if you forget say one or two values, the prompt feature works fine. Im now getting into Javascript and can see that it is a very useful language, however are there any editors that will provide prompt/suggestion pop ups when editing which are free? If possible, one that combines HTML/CSS/Javascript all together. I've seen this:- http://download.cnet.com/Free-JavaSc...-10907077.html And was going to give it a download. But anyone know of any others or can recommend the above? Thanks Hi, I am hoping I just need to be pointed in the right direction with this. I have Page1. When Page1 body onloads it uses Ajax to call PartA Within PartA I have a message board so members can write messages which will be sent to my database in PartA[1] and immediately posted for view on to PartA[2]. As I want to have my request to the server updating regularly I want to have PartA[2] on a timed loop to refresh - I do not need the content of PartA[1] to refresh. So the order of events would look like this: Page1 | onload call | v PartA / \ V V PartA[1] PartA[2] (loads once) (constantly refreshes) What I am not sure about is that I have <body> and <head> attributes in Page1 only. I have already used my body onload to call PartA (and can't use it to call PartA[2] before PartA has loaded anyway). I do not want the user to have to click a button or do anything to call up PartA[2]. So my question is how would I get PartA[2] to automatically load within PartA? I hope I have made this clear, but if I haven't let me know and I will try again. i have a html wich i am working on .. Code: <html>

now my problem is the password is not sent to the perl script i basicly modified an ajax from another form to do this form. when the "go" is pressed the username is sent and a string is recived and devided into the form inputs.. all i need to do now is send the password along with the username the username variable is "u" i would like the password variable to be "p" any ideas hi; This is my first post and am abit stuck. I used JQuery AJAX to get data from a different page and show it in my div. This all works fine but now i want the page collected by AJAX to execute a Javascript function which is in the page which request the AJAX page. I have this so far but its not working. This is in the AJAX-ed page. Code: <a href="#" onClick="change_postcode(prompt('Please Enter Your Postcode', 'SW10')");
)">SW10</a>
And the page which requested the AJAX page. Code: <script type="text/javascript">
function change_postcode(postcode){
$('#view8').html('<p><img src="http://www.MySite.com/images/loading.gif"/><br />Loading! Please Wait...</p>');
$('#view8').load("http://www.mywebsite.com/include.php?inc=Events&when=&postcode="+postcode);
}</script>
I though about using top but that didn't work. Code: <a href="#" onClick="top.change_postcode(prompt('Please Enter Your Postcode', 'SW10')");
)">SW10</a>
How can i get my AJAX page to execute a Javascript function which is in the page which contains the the AJAX page. Thankyou all for reading my post Paul P.S Am very sorry for my way with words. I was wondering if someone would have the time to talk and help explain some Ajax things to me... slowly. I'm trying to make my web sites more dynamic. Like I just need someone I can bounce ideas off and they can walk me through step by step on how to do them. Thanks Shelby I need some help with some javascript I am trying to put on an IF forum. http://s7.invisionfree.com/AJAXTEST/index.php At the very top, you will see a link called "on this link". It is an ajax code. If you click on it, a blank alert box comes up. However, if you go he http://commx.info/will/test.html and click on the same link, the alert box has the text I am looking for. It uses the exact same code, so I can't figure out why it works on a plain page and not on an IF forum. Does anyone have any ideas? The code is Code: <html><head>
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"><script>
function callback(serverData, serverStatus) {
alert(serverData);
}
function ajaxRequest() {
var AJAX = null;
if (window.XMLHttpRequest) {
AJAX=new XMLHttpRequest();
} else {
AJAX=new ActiveXObject("Microsoft.XMLHTTP");
}
if (AJAX==null) {
alert("Your browser doesn't support AJAX.");
return false
}
AJAX.onreadystatechange = function() {
if (AJAX.readyState==4 || AJAX.readyState=="complete") {
callback(AJAX.responseText, AJAX.status);
}
}
AJAX.open("GET",'http://commx.info/accounts/codes/shout/ipb13/getChatData.php?lastID=0', true);
AJAX.send(null);
}
</script>
</head><body><a href="javascript:ajaxRequest()">on this link</a></body></html>
Hello everyone. I was working on a ajax function and I can't seem to figure out what I'm doing wrong here. I'm kinda new with the prototype method I was wondering if I could get some help figuring out what I'm doing wrong here exactly and how I can fix this. Any help on this would be wonderful. Thanks, Jon W Code: function createAjax() {
if(!this.http && window.ActiveXObject) {
try {
this.http = new ActiveXObject("Msxml2.XMLHTTP" || "Microsoft.XMLHTTP");
}
catch(e1) {
this.http = false;
}
}
if(!this.http && window.XMLHttpRequest) {
try {
this.http = new XMLHttpRequest();
}
catch(e2) {
alert("Sorry we was unable to make a request between your browser.");
}
}
}
createAjax.prototype.request = function(url) {
var rmd = Math.random();
this.http.open('get', url+"&rmd="+rmd, true);
this.http.send(null);
this.http.onreadystatechange = this.responseHandler;
}
createAjax.prototype.responseHandler = function(obj) {
if(this.http.readyState == 4) {
document.getElementById(obj).innerHTML = this.responseText;
}
}
function ajax(url, obj) {
a = new createAjax();
a.request(url);
a.responseHandler(obj);
}
var doAjax = new ajax('ajax.php?name=jon','content');
I have a formula done in PHP. Lets say it's PHP Code: $sum = $_POST['one'] + $_POST['two']; I have 2 textboxes, one named "one", the other named "two". I want the page to also display the answer under the text boxes but it updates in real time when you input a value into the textboxes. How would I do that? Anyone got examples of how to cache an ajax result. Search pulls details from database and an xml feed, and I need to link to results, cant do a post request from browser by a link request, so is there any way to cache whats displayed and link to the cache. thanks Hello, I am looking to created a login system where a user will take his/her photo via webcam in browser and that picture taken should be related to that user; under a specific timestamp, for example, if my user name is username and I logged In, the system will note my time and by taking a photo (either auto or by clicking a button in browser) and will store that picture in a folder under a unique name related to that customer and the time he logged in, I am stuck how to connect web cam to browser (desirable ajax etc not flash) and then photo taken and stored in a folder with unique name etc anybody did something like this before? help appreciated. Right, I've been searching for a few days now and i'm looking for a AJAX/JQuery script where i can load external content in to a div. I've seen a few site's that have it, and im after it so when i click the page link it loads it in the address bar like this http://www.google.co.uk/#content/index.php or what ever. Thanks. I have the following ajax code: Quote: ............. ............. ............. XHR.createXMLHttp(); XHR.open("POST", "/cgi-bin/addpost.cgi", true); XHR.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); XHR.onreadystatechange = function() { if (XHR.readyState == 4) { if (XHR.status == 200) { alert("Operazione effettuata con successo"); } else { alert("Operazione non riuscita"); } } } XHR.send(url); The function send data, but it don't return never alert windows. Where is the problem? i have found a very simple ajaxexample on the internet, when this works i can adept it to my site, but it doesn't work :-( anybody sees why? Code: <div align="center" id="timeval">--:--:--</div>
<button id="stop">Stop</button>
<script src="jquery.js"></script>
<script>
$(document).ready(function()
{
//ajaxTime.php is called every second to get time from server
var refreshId = setInterval(function()
{
$('#timeval').load('ajaxTime.php?randval='+ Math.random());
}, 1000);
//stop the clock when this button is clicked
$("#stop").click(function()
{
clearInterval(refreshId);
});
});
</script>
and the phpscript:
ajaxtime.php
<?php
echo date("g:i:s A");
?>
so i have this "class" defined in a javascript file, "a.cross-link". This enables the ability for users to navigate the webpage in a slider format. it works fine if I directly place the required html code: Code: <a class="cross-link" href="#3" title="Go to Page 2">View Results</a> but if i have php print out that line for me, it doesn't work: PHP Code: echo "<a class= \"cross-link\" href=\"#3\" title=\"Go to Page 3\">$name</a>";( Where $name is some variable) Note: the php code is just your average sql stuff. here is an interesting observation i've made: if i "hardcode" this this into the html: <a class="cross-link" href="#3" title="Go to Page 3">View Results</a> and then i go to generate the sourcecode, this is what appears (this works): <A class=cross-link title="Go to Page 3" href="#3" jQuery1283131847233="30">View Results</A> but if i have the html made by a php echo statement, it just stays the same - i dont get a jQuery1283131847233="30" generated in the sourcecode. i'm sorry i'm having difficulty describing the problem. i'm new to jquery and ajax stuff. to me, it seems like the "cross-link" class i have defined in the javascript isn't being applied to correctly. i have no idea. can you invoke javascript from a php echo statement that is formatted to produce html code? here is another thing i believe is true: when the page loads, the javascript loads. the users, through the use of ajax, submitts a sql querey and navigates, using a jquery slider, to another div (where i want the user to go after selecting a resulting link from the sql query). so the javascript is going to execute before the list of results is produced. do I need to rerun the javascript each time new php produced sql data is populated in a div? if so, how? i dont know what more information you may need, so please ask. Thanks. |
