JavaScript - Ajax Call Refreshes Page
I'm poking in the blind with javascript and hope that you can help with this issue.
A javascript function is making a call to an external php file, which checks the compares the current time with a time stored in a mysql database. If a certain time passes, the php will send back instructions to redirect the user to a different page. The issue is that the page refreshes every time the is javascript function is executed. This resets any forms, or videos that the user is watching on the page. Here is the relevant code: Code: function checkTimer()
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
window.location.href = xmlhttp.responseText;
}
}
xmlhttp.open("POST","php/5minforpage10.php",true);
xmlhttp.send();
}
window.setInterval(checkTimer,15000);
Is there a way to achieve the goal of checking the time against the server time (via the php code) without refreshing the page? Thanks kindly! 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. OK, I've just been working with kwyl, trying to intergrate a like/dislike script to her site. There was an original script, and although bugged, it's almost the What works The user clicks the like/dislike icon. Ajax sends a request to PHP: Either the like/dislike gets inserted into the database. OR, if the user has already liked/disliked that post, an alert error gets returned. What doesn't work If you click to like/dislike a post, it won't appear (the current count is in brackets beside the icons) unless the page is refreshed. How would I use this along side Ajax for auto update? $data = mysql_fetch_object(mysql_query('SELECT `like`,`unlike` FROM posts WHERE id="'.$row['id'].'"')); It's used he Code: $data = mysql_fetch_object(mysql_query('SELECT `like`,`unlike` FROM posts WHERE id="'.$row['id'].'"'));
?>
<br />
<div class="vote">
<a href="javascript:;" onclick="doAction('<?php echo $row['id']; ?>','unlike');">
<input type="image" name="submit" src="images/down.gif" /></a>
(<span id=""><?php echo $data->unlike;?></span>)
<a href="javascript:;" onclick="doAction('<?php echo $row['id']; ?>','like');">
<input type="image" name="submit" src="images/up.gif"></a>
(<span id=""><?php echo $data->like;?></span>)
I hate javascript and this is utterly driving me up the wall. Any help would be much appreciated. If you need more informaton/code please ask. You know how google has different ads everytime you go to a page? Well i want to do the same thing. I got two banners and i want one to change to the other banner when someone refreshes the page.
I'm just trying to make a simple interface. On the html form the user enters the time to start, time to end, and frequency of a reminder alert. I pass this to my javascript and then am trying to setup a 1 second loop where it checks against the clock to see if it's time to begin the reminders. I get to the function, but the setTimeout doesn't complete and my page just refreshes. Here's my javascript code for this section.... Code: //-----------Start Countdown---------------------------
function StartCountDown(startTime, endTime, freq){
now=new Date();
intToStart=startTime-now;
intInSec=intToStart/1000;
alert(intInSec + " sec");
if (now > startTime){
StartRepeat(endTime, Freq);
}
else{
var TTS=setTimeout("StartCountDown(startTime, endTime, freq);", 1000);
}
}
function StartRepeat(endTime, freq){alert("Made it to StartRepeat Function");
if (freq != 0){
var task=setInterval("TaskRemind(endTime, freq)", freq);
}
else{
clearTimeout(task);
}
}
function TaskRemind(endTime, freq){
alert("Do Task Now!");
now=new Date();
if (now <= endTime){
StartRepeat(endTime, freq);
}
else{
freq=0;
StartRepeat(endTime, freq);
}
}
Any help is greatly appreciated. Brian Right for day's i've searching for a jQuery/js/ajax script that opens like facebooks box where you can delete things update posts and so on...

I'm not good with js/jQuery/ajax.... Thanks. hihi i am doing a project regarding ajax how am i going to call the title because normally if you call start year is like var detail = eval.... then for loop it inside should be var start year="" startyear += ...[i].startyear something like this but how am i going to call the title inside the note?

i'm doing the following on a select box to load the next select box (in a td with the id) if I look at the html returned by the ajax call I get PHP Code: <select name=optionvalue /><option value='test 1'>test 1</option><option value='test 2'>test 2</option><option value='test 3'>test 3</option></select> but it's showing as the select box and then test 1test 2test 3 my javascript code is PHP Code: function Loadoptionvalueselect() { //alert("here"); urltoajax = "getoptionsvaluesselect.asp?1=1" strarea = document.getElementById('optionid').value; urltoajax = urltoajax + '&optionid=' + strarea urltoajax = urltoajax + '&rnd=' + Math.round(Math.random() * 10000) // alert(urltoajax); $.ajax({ url: urltoajax, cache: false, success: function(html) { $("#troptionvalue").html(html); } }); } any ideas what could be causing this? Hi, I have a form which goes to my insert page which inserts the data into the table. Except I didn't want to do a redirect to another page so I thought I would do an Ajax call. Both pages work until I change it to an ajax call. I am pretty certain that it is because I took out the <form action="insert.php"> because otherwise the page would redirect but if that is the case I don't know my way around it and if it isn't the problem I'm not sure what is. But here is my code: Form: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<html><head>

}
xmlhttp.open("POST",File,true);
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(ID).innerHTML=xmlhttp.responseText;
}
}
xmlhttp.send();
}
</script>
</head>

</form>

And my insert.php is: Code: <?php
$con = mysql_connect("localhost","user","password");
if (!$con){
die('Could not connect: ' . mysql_error());
}
mysql_select_db("mydb", $con);
$sql="INSERT INTO abc (para1, para2, date, time)

('{$_SESSION['para1]}', '{$_POST['para2']}',CURDATE(), CURTIME())";
mysql_query($sql) or die('Error: ' . mysql_error());
mysql_close($con)
?>
Hi there How to send data from a text feild in GET method using an AJAX call... I already have codes working Code: to = "interfaces/add_department.jsp";
parm = "name="+name.value+
"&name2="+name2.value;
alert(parm)
post(to,parm,callBackFunctionForAddDepartment);
Here the variable name may have "me&you" or "me you" like that.... so how do i encode it so that it reaches properly? 0 down vote favorite I have been struggling with this for some time.. I searched around but didnt get a solution yet. This is only an issue on production server. In my development environment, everything works just fine. I am using JQuery/Ajax to update product information based on product's Color attribute. for example, a product has A and B color, the price for color A is different from color B. When user choose different color, the price information is updated as well. What I did is to first add a javascript function: function updateProductVariant() { var myval = jQuery("#<%=colorDropDownList.ClientID%>").val(); jQuery.ajax({ type: "POST", url: "/Products.aspx/GetVariantInfoById", data: "{variantId:'" + myval + "'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (response) { var obj = jQuery.parseJSON(response.d); jQuery("#<%=lblStockAvailablity.ClientID%>").text(obj.StockMessage); jQuery(".price .productPrice").text(obj.CurrentPrice); jQuery(".price .oldProductPrice").text(obj.OldPrice); } }); } Then I can register the dropdown list's 'onclick' event point to function 'updateProductVariant' GetVariantInfoById is a Web method in the codebehind, its also very straightforward： [WebMethod] public static string GetVariantInfoById(string variantId) { int id = Convert.ToInt32(variantId); ProductVariant productVariant = IoC.Resolve<IProductService>().GetProductVariantById(id); string stockMessage = productVariant.FormatStockMessage(); StringBuilder oBuilder = new StringBuilder(); oBuilder.Append("{"); oBuilder.AppendFormat(@"""{0}"":""{1}"",", "StockMessage", stockMessage); oBuilder.AppendFormat(@"""{0}"":""{1}"",", "OldPrice", PriceHelper.FormatPrice(productVariant.OldPrice)); oBuilder.AppendFormat(@"""{0}"":""{1}""", "CurrentPrice", PriceHelper.FormatPrice(productVariant.Price)); oBuilder.Append("}"); return oBuilder.ToString(); } All these works fine on my local box, but if i upload to the production server, catching the traffic using fiddler, /Products.aspx/GetVariantInfoById becomes a 302 Object moved Object moved to here. On my local box, HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 03 Mar 2011 09:00:08 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private, max-age=0 Content-Type: application/json; charset=utf-8 Content-Length: 117 Connection: Close But when deployed on the host, it becomes HTTP/1.1 302 Found Proxy-Connection: Keep-Alive Connection: Keep-Alive Content-Length: 186 Via: 1.1 ADV-TMG-01 Date: Thu, 03 Mar 2011 08:59:12 GMT Location: http://www.pocomaru.com/Products.asp...d/default.aspx Server: Microsoft-IIS/7.0 X-Powered-By: ASP.NET then of course, then it returns 500 error title>Unknown web method GetVariantInfoById/default.aspx. Parameter name: methodName Can someone please take a look? I think its some configuration in the production server which automatically redirects my webservice call to some other URL, but since the product server is out of my control, i am seeking a local fix for this. Thanks for the help! Sorry for the title- i'm doing my best to describe my problem. So this is basically it: I have some javascript onmouseover events that change the content of an iframe. The problem is that within the javascript calls, I have some url's attached to rollover buttons INSIDE the parent div's that are being manipulated by javascript. So the iframe refreshes properly when its supposed to, but it ALSO refreshes as each of the links inside the effected div are rolled over as well. So there is too much extra refreshing and lots of clicking noises because of the Internet Explorer default noise settings. The easiest way to see what im talking about is to go to: http://maybetheworldisending.com/fre...HOMEPAGE_jan4/ An example of the problematic code is as follows: Code: <div class="beachcomberoff" target="mainbox" onmouseover="ShowPage('frame1_slider');this.className='beachcomberon'" onmouseout="this.className='beachcomberoff';">
<div id="turquoise1"><a href="#"></a></div><div id="coral1"><a href="#"></a></div><img src="HOMEPAGE_jan4_web/beachcomber.png" width="453" height="330" border="0"></div>
The prob is that the div's named turquoise1 and coral1 are being effected by the javascript on the containing div. How do i make it unaffected by that js? Is there something like a "onmouseover=do nothing" or something of the sort? HI I have tow page and the first page open a new window with javascript(by using window.open).Now I want to call a javascript function that is in the first page from the second page and for that i use parent.function_name but it doesn't work.How can do so? thanks <frameset rows="30%,70%> <frame src="page1.html" name="name1" frameborder="0"></frame> <frame src="page2.html" name="name2" frameborder="0"></frame> </frameset> in above code I used page1.html & page2.html as frame. Both include same javascript file having two function name fun1() & fun2(). as both are separate frame both have there own copy function page1.html fun1() fun2() page2.html fun1() fun2() I call fun2() from page2.html and inside that function I want to call page1.html's fun1(). fun1() in page1.html and fun1() in page2.html both return different result because of there global variables. Is there any way to call fun1()-page1.html from the fun2()-page2.html? All, I have the following code: Code: $(function() {
$("#check_login").click(function() {
event.preventDefault();
var $email = $("#login_email").val();
var $password = $("#login_password").val();
$.post("check.php", {email: $email, password: $password}, function(result) {
if(result=="Success"){
parent.$.fancybox.close();
window.location.replace("index.php");
}else{
$("#login_check").html(result);
$("#login_email").val('');
$("#login_password").val('');
}
});
});
});
I'm basically checking a user login. If the login is successful I'd like to close the Fancybox. This part works fine. I'm using an iFrame from Fancybox. If I don't have this part: Code: parent.$.fancybox.close(); It will reload the index page in my iFrame. How can I refresh my other page from the iFrame? Thanks in advance. Hi, I'm making a page and I'd like to start an applet (Jmol) and display it near the button of the current page when a button is clicked. However, I get a syntax error: "missing ; before statement" (Note: this javascript is part of a cgi page) The code I have is as follow: Code: <script type="text/javascript" SRC="../jmol-12.0.48/Jmol.js"></script>

print "<a href=javascript:loadJmol(\"SomeString\")>View</a>";
print "<script id=\"viewMol\"></script>";
The syntax error occurs at the single quote in ...").innerHTML = 'jmolInitialize("... I have been able to get this applet to run when not in a function. Has anyone run into this before and can give me a hand? Thanks, Tom hey guys i have been trying for the last week to make a one of a kind login page. but i cannot figure out how to make the Slide bar initiate a Form submition i have made a sample page on jsfiddle shown here http://jsfiddle.net/Cav3maN/ZzwQq/embedded/result/ if your not farmiliar with jsfiddle just remove the embedded/result/ to see the source http://jsfiddle.net/Cav3maN/ZzwQq/ please feel free to modify the source and get it to submit. if your slider disapeers click the "Run" tab at the top. and when you get it successfully working click "Update" tab and send the new url on here for me to see. thanks very much. aslo this is a free source feel free to embed it in your site anywhere. thanks alot and please guy i beleve in you all lol im new to web coding and i wanna be successful so if you wish to show me exactly what you done to make this work i would love you for ever. We have an html page which brings in content dynmically using Ajax. So the page starts out with certain content, and when a particular link is clicked, the content is swapped out with new content. With this approach, the back button on the browser does not work, because the URL didn't actually change. How could a user bookmark the new page with the second set of content? Is this even possible?
Hey, I have 3 bits of code, 2 of which I'm pretty sure are right [i know the php works, and the ajax looks fine], but one i'm having trouble with. Basically what I'm trying to do is use a link to call php function [calls a piece of text from a database]. Which worked fine. But then I tried to incorporate AJAX into the script to make change dynamically on the page, and I'm a little confused with it all. I've got the AJAX and PHP, [and an attempted page with a link on to try and call the function with AJAX] but so far it's not doing as it should. Wondered if anyone could show me where I'm going wrong with the whole 'linking together' thing? So far everything I've tried hasn't worked. [hope this doesn't violate the forums 'don't dump your code' rule. But it's kind of all necessary] The AJAX [AJAX.js]: Code: function loadurl(generate.php) {
var ajax = false;
// Create the object:
// Choose the objecttype, depending on what is supported:
if (window.XMLHttpRequest) {
// IE 7, Mozilla, Safari, Firefox, Opera, most browsers:
ajax = new XMLHttpRequest();
} else if (window.ActiveXObject) { // Old IE-browsers
// Make the type Msxml2.XMLHTTP, if possible:
try {
ajax = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e1) { // Else use the other type:
try {
ajax = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e2) { }
}
}
// Retrieving the data from the page
if (ajax) {
alert("url:generate.php" + url);
ajax.open('GET', url);
// Sends request
ajax.send(null);
// Function that handles response
ajax.onreadystatechange=function(){
// If everything is OK:
if ( (ajax.readyState == 4) && (ajax.status == 200) ) {
// Returns the value to the document
alert(ajax.responseText);
}
}
} else { // AJAX is not useable
alert('It is not possible to connect, please update your browser.');
}
}

I've included the file names with extensions just in case it's something to do with those, but thanks in advance for any help. Greatly appreciated. I have been searching online for hours, but it is possible I'm just not thinking of the correct keywords. I have included a basic illustration of the current setup (which does not work). The issue lies with the page that is the desired output. I have a far deeper issue which I have narrowed down to javascript on the final .asp page not loading at all. On default.asp, I am calling a function contained in 'ajax_call-contentselection.js' Code: <a onclick="func_displaycontents('restaurants'); return false">displayajaxcontent</a>
Honestly, I don't believe the following piece of code (ajax_call-contentselection.js) is relevant, as it is standard ajax code, but just in case: Code: function func_displaycontents(var_type){
var xmlHttp = GetXmlHttpObject();
var url = "../_include/ajax_display-contentselection.asp";
url += "?type="+var_type;
if (!xmlHttp){
alert ("Browser does not support HTTP Request")
return
}
xmlHttp.onreadystatechange=function(){
if(xmlHttp.readyState == 1){
document.getElementById("div_ajaxfillattractions").innerHTML = "<div style='padding-top:50px;color:white;width:930px;text-align:center;'><img src='../_images/ajax-loader.gif'/><br/>Loading...</div>";
};
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
document.getElementById("div_ajaxfillattractions").innerHTML=xmlHttp.responseText;
}
};
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
}
The other contents of "ajax_display-contentselection.asp" are displayed properly in "div_ajaxfillattractions" of "default.asp", but no javascript code on that page loads. If I use "ajax_display-contentselection.asp" as an include file on "default.asp", I get the javascript alert of 'Success', but when I initiate the AJAX it does not work, so I know there isn't a problem with the javascript. Please let me know if I sucked at explaining something, or more detail is needed. Thanks in advance, Matt Hello, I actually use a counter on a webpage (It works) To do it, I use an inline javascript but I would like to unify the entire page and call that counter directly in the external Javascript that manages the whole site. Here's the actual code... Code: HTML
<body onLoad=gen_hits()>
...
<span id='hits'></span><SCRIPT language="JavaScript" SRC="http://www.mycompany.com/cgi-bin/counterdir/gcount.pl?NUMBER=../../otherdir/counter"></SCRIPT>
...
</body>
EXTERNAL JAVASCRIPT (ini.js)
var hits="HITS ";
function gen_hits() {
document.getElementById("hits").innerHTML=hits;
}
and here a "view" of my request... Code: HTML
<body onLoad=gen_hits()>
...
<span id='hits'></span>
...
</body>
EXTERNAL JAVASCRIPT
var hits="HITS " + <SCRIPT language="JavaScript" SRC="http://www.mycompany.com/cgi-bin/counterdir/gcount.pl?NUMBER=../../otherdir/counter"> </SCRIPT> ;
function gen_hits() {
document.getElementById("hits").innerHTML=hits;
}
Any idea how to modify it ? Thank you very much Gino |
