JavaScript - Ajax Can't Connect?
I was wondering if there's a quick and simple way to notify a user if an ajax connection is broken, for example you're calling a file, but due to your internet connection, the file cannot be relayed back to you, so the existed javascript code on the initial page you're on, notifys you of the problem.
Any ideas? Similar TutorialsHi, 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. Hello, I am very new to HTML. Yesterday I have started learning HTML.

Basically, we have phone server that is constantly streaming XML data on port 1024 (serverIP:1024). I've ran a packet sniffer and was able to gather the elements and attributes for the XML data that the server is streaming. Now, I have a test XML parser which works with the XML document using the elements and attributes i've gathered from the packet sniffer. Is there a way for me to connect to the TCP port i've mentioned using javascript and incorporate it with the XML parser that I have. Here is the code for my XML Parser. Quote: <html> <body> <script type="text/javascript"> var xmlDoc; if (window.XMLHttpRequest) { xmlDoc=new window.XMLHttpRequest(); xmlDoc.open("GET","acddataentry.xml",false); xmlDoc.send(""); xmlDoc=xmlDoc.responseXML; } // IE 5 and IE 6 else if (ActiveXObject("Microsoft.XMLDOM")) { xmlDoc=new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; xmlDoc.load("acddataentry.xml"); } document.write("<table border='1'>"); var x=xmlDoc.getElementsByTagName("ACD"); for (i=0;i<x.length;i++) { document.write("<tr><td>"); document.write(x[i].getElementsByTagName("Calls_Waiting")[0].childNodes[0].nodeValue); document.write("</td><td>"); document.write(x[i].getElementsByTagName("Crt_Wait_Time")[0].childNodes[0].nodeValue); document.write("</td></tr>"); } document.write("</table>"); </script> </body> </html> Any help on this is highly appreciated. Thank in advance. HI, Is it possible to connect to a sqlite database via javascript. And I do not mean the HTML 5 Web SQL Database, that is no problem. What I mean is a file-based SQLite database, which is in the same folder as the HTML page.Also, I can not use something like Google's API, only the javascript libraries I can then put in this folder. THX Helge I wrote a script that registers scrolling action as a number, and is stored in the variable delta. Now, I only want to use that variable when scrolling over the div section1 on the page. What would that look like ... this? Code: function something()
{
if(section1.delta < 0)
do something here;
}
Hello there everyone, I've been stuck on this for about a day and a half. My code is for a connect four game in Javascript. The problem resides in the minimax recursion AI function. Code: function bestMove(color,depth,maxDepth)
{//Finsd the best move for the side. Returns column and score pair
//depth specifies current level of depth (should be passed as 0)
//maxDepth specifies the maximum depth to search
//holds the best score
var best = new Worth(-100000,0);
if(depth%2==1)best.Score*=-1;
var mv = new Worth(0,0);
for (i=0;i<7;i++)
{ //try putting a piece at each of 7 columns.
mv.Column=i;
if(height[i]==-1){
}else{
//find the row to put this piece.
gameB[height[i]][i]=color;
height[i]--;
alert(""+i+"");
//find if it is a game over, don't search further if it is
//a score of 100 or -100 means a game over
var cur = new Worth(0,0);
cur.Score=checkWin(height[i],i,color);
if(cur.Score==gold){
cur.Score=-100;
}
if(cur.Score==silver){
cur.Score=100;
}
if(cur.Score==100||cur.Score==-100||depth==maxDepth){
mv.Score=cur.Score;
}else{ //search further (this one is the recursive call
if(color==gold) {
color = silver;
}else{
color = gold;
}
mv.Score=bestMove(color,depth+1,maxDepth).Score;
}
//if this move is better, use it instead
if(mv.Score>best.Score&&depth%2==0)
best=mv;
else if(mv.Score<best.Score&&depth%2==1)
best=mv;
//undo the move. Remove the piece you just put
if(getIt(height[i],i)==outside)
{ alert("OH JEEZ");
}
}
}
return best;
}
I cannot figure out what is wrong exactly. There maybe a serious error of logic within the function. I posted the .html file on my website www.softdrawing.com/connect4.html with the whole code. If someone could help me fix that function please that would be amazing. I'm new to the minimax algorithm and I tried writing it for myself.

If someone could please guide me in the right direction I would greatly apprieciate it. Thanking You. What I am trying to do is make a little box that when you hover over it, it will move to a random position. What I am having trouble with is the JavaScript. I have made the code for everything, EXCEPT to move it to a random position. Here is my code so far: Code: <style type='text/css'>
#circle1 {
background:#007fff;
height:20px;
margin:0px;
position:absolute;
width:20px;
left:5px;
top:5px;
-webkit-transition:left 2s linear, top 2s linear;
}
#circle1:hover {
left:25px;
top:25px;
-webkit-transition:left 0s linear, top 0s linear;
}
</style>
<div id='circle1'></div>
I would like the left: and top: in the #circle1:hover to be a random number, to make it go to a random position. I have no clue how to do that though...

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');
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>

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 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 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");
?>
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 What in the world is wrong with this? I have been looking at it for hours. Code: $.ajax({
url: "wifitos.html",
type: "GET",
dataType: "html",
error: function(){ $("#loading").html("Error Loading Site. Try again later.");},
beforeSend: function(){ $("#loading").show("fast");},
complete: function(){ $("#loading").hide("fast");},
success: function(html){
$("#panel_content").show("slow");
$("#panel_content").html(html);
}
});
All the HTML tags are right. It shows the loading properly, but does not return an error and just says loading forever without loading wifitos.html. Help appreciated! FIXED! DON'T REPLY TO THIS THREAD: After hours of trying to figure this out, I find it 10 sec after I post this thread. Go figure. It was because I had a return false before the ajax. Hi, I have an ajax script that I would like to use to retrieve a password hint from a database. Both the ajax script and the php retrieval script are stored on the same domain (we'll call it domain1.com), but the ajax script runs on another domain (domain2.com). All the scripts are working fine, individually, but when I try to integrate them, I'm getting a ready state of 4, but an HTTP status of 0. I've traced the code flow and the retrieval script is being called by the ajax script OK and it's echoing all the right stuff, but it's just not getting back to calling ajax routine. I've read that an ajax routine can only call a script that resides on the same domain that it runs on. Is this correct and, if so, does anyone know of a work around, because I really need to be able to store the ajax script on domain1 and run it on domain2? If not, then can anyone suggest why I'm getting an HTTP status of 0, when all the individual components are working fine? Debbie http://sorgalla.com/projects/jcarousel/ I would like to use this jcarousel. I dont use AJAX, I just want to set it up with script in my head and html on my website. Is this possible or do I have ot use AJAX? I am not familiar with it at all.. I completed the steps it said. I put the folder in my directory. I added the script to my head code, as well as the other one. I then also added the other two scripts in my html where I would like them to be. It's not showing up so I know I am missing steps or not doing it correctly Help anyone? THANK YOU!!! |
