JavaScript - Simple Javascript Redirects Not Working...please Help...
Do you see anything wrong with this code...
Code: <SCRIPT LANGUAGE="JavaScript">
if(GetCookie('upgrade8') != null) {
location.href="cookie-in.html"
}
</SCRIPT>
Also tried this (didn't work either)... Code: <SCRIPT LANGUAGE="JavaScript">
var readCookie = getCookie("upgrade");
if (readCookie("upgrade") != null){
// if cookie already exists, go to url
document.location = "lesson1";
} else {
// else go someplace else
document.location = "lesson2";
};
</script>
I've tried posting in both the head and body. Still can't get it to redirect. I'm a little new to this. Your help would be appreciated. thanks Similar Tutorialsi am new in programming and learning it from lynda but i am trying to make a program which according to me is good enough but its not working and i am using free javascript editor for compiling and coding <!DOCTYPE html> <html> <body> <script> var a = 5; var b = 10; var c = 30; var d = a + b + c; alert("the value of d is" + d); </body> </html> Please tell me where is it i am making mistake Reply With Quote 01-08-2015, 11:56 PM #2 Old Pedant View Profile View Forum Posts Supreme Master coder! Join Date Feb 2009 Posts 28,311 Thanks 82 Thanked 4,754 Times in 4,716 Posts You forgot the </script> ending tag. I have a simple javascript for validating the radio buttons. But for what ever reason window.location does not redirect. this is my code: <SCRIPT LANGUAGE="JavaScript"> function checkRadio (frmName, rbGroupName) { var radios = document[frmName].elements[rbGroupName]; for (var i=0; i <radios.length; i++) { if (radios[i].checked) { return true; } } return false; } function valFrm() { if ( checkRadio("frm1","radio1")==true && checkRadio("frm1","radio2")==true) window.location="price.jsp"; else alert("You didnt select any price"); } </script> when i replace an alert with the redirect line it works fine. any help would be appreciated. I imagine this would be very simple for someone who knows javascript. I want to have three fields. First field is "posted speed limit", second field is "actual speed" and third field will be the output field. All the script needs to do it subtract the posted speed from the actual speed and add a ZERO to the end; which is the amount of the speeding ticket. The minimum fine is $100, however. So, 5 miles over the speed limit would be $100 (minimum value) 15 miles over the speed limit would be $150 (add a zero) 35 miles over the speed limit would be $350. etc. I know very little Javascript, if anyone could help me out with this, I'd appreciate it. Thanks, Sean I hope I have this post in the right place! Any help would be very much appreciated... I have a feature on my website that allows users to choose the website background (using alternate css sheets) and then uses an externally linked javascript file to store the background choice as a cookie so it is consistent throughout the website. This works perfectly locally (i.e. when previewing my website on my computer) but now it is uploaded to my host it doesn't appear to be working. (with the same browser) My javascript is he http://www. b r p - e n v .com/javascript/backgroundchange.js (with no spaces) The website that the javascript file is linked to is http://www. b r p - e n v .com (with no spaces) In the head I have: <script type="text/javascript" src="../javascript/backgroundchange.js"></script> ...then I have: <body onload="set_style_from_cookie()"> ...and for users to choose which background: <form> <input type="image" src="../images/white-background-thumb.jpg" onclick="switch_style('bg1');return false;" name="theme" value="White" id="bg1"> etc... </form> My problem is: The background reverts back to the default when moving to a different page. This would indicate that the background choice is not being saved in cookies. But this works locally! I have tried putting the javascript directly onto each page but I still had the same problem. I hope someone can help, I will be so grateful if I can get this to work. Many thanks indeed! Edit: Please move me, I think it's the wrong forum! PHP Code: Adding this counts twice which proves that the page redirects twice, how to fix? <?php session_start(); if(isset($_SESSION['views'])) $_SESSION['views'] = $_SESSION['views']+ 1; else $_SESSION['views'] = 1; echo "views = ". $_SESSION['views']; ?> For some reason this form redirects twice to the same page Adding the form action to users.php doesn't help 'cause the checkboxes don't retrieve the updated data. PHP Code: <script type="text/javascript"> <!-- function un_check(){ for (var i = 0; i < document.frmactive.elements.length; i++) { var e = document.frmactive.elements[i]; if ((e.name != 'allbox') && (e.type == 'checkbox')) { e.checked = document.frmactive.allbox.checked; }}} //--> </script> </head> <body> <form action="" method="post" name="frmactive" id="frmactive"> <div align="right"> <input name="activate" type="submit" id="activate" value="Activate" class="adduser" /> <input name="deactivate" type="submit" id="deactivate" value="Deactivate" class="positive" /> </div> <?php // Check variable... if(isset($activate)){ for($i=0;$i<$count;$i++){ $user_id = $checkbox[$i]; // update accordingly... $sql = "UPDATE users SET status = 'Y' WHERE id = '$user_id'"; $result = mysql_query($sql) or die(mysql_error()); } /*** *** No clue why this is needed but if you don't refresh the page - you don't see the updated data? *** ***/ // if successful redirect if($result){ echo '<meta http-equiv="refresh" content="0;URL=users.php">'; } // *** } if(isset($deactivate)){ for($i=0;$i<$count;$i++){ $user_id = $checkbox[$i]; // update accordingly... $sql = "UPDATE users SET status = 'N' WHERE id = '$user_id'"; $result = mysql_query($sql) or die(mysql_error()); } /*** *** No clue why this is needed but if you don't refresh the page - you don't see the updated data? *** ***/ // if successful redirect if($result){ echo '<meta http-equiv="refresh" content="0;URL=users.php">'; } // *** } mysql_close(); ?> ... HTML data ... </form> Is there a better way to update MySQL via checkboxes? Hi, I'm trying to make a form that when you click "submit", the original page goes somewhere, and it also creates a popup for the action URL. Currently, I can get the popup portion, but the can't get the original window to redirect somewhere else. this is what I have in the head. Code: <SCRIPT TYPE="text/javascript">
<!--
function popupform(myform, windowname)
{
if (! window.focus) return true;
window.open('', windowname, 'height=200,width=400,scrollbars=no');
myform.target=windowname;
return true;
}
//-->
</SCRIPT>
And this is what I have in the body Code: <form id="update" action="update.php" method="POST" name="update" onSubmit="popupform(this, 'join')"> Hi I am new to teaching JavaScript I need to show how to create a form with validation and feedback.

This script is a search engine, when you look for something say the word "titanic" , he shows you a list of results with numbers, being the first link with the higher number (kinda like a score), and then after u click the link you want he goes to the respective page. Now i want him to skip the results page, and directly open the first link that he founds on the page.

Hi. Just started fooling around with Ajax a bit back. So far, it's been fine. Today, though, I'm hitting some error I can't figure out. It *should* work, but it doesn't, and I have no idea why. Simple HTML form page with a bit of css. No big deal. Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<script type="text/javascript" src="livesearch.js"></script>
<style type="text/css">
#livesearch
{
margin:0px;
width:194px;
}
#txt1
{
margin:0px;
}
</style>
</head>
<body>
<form>
<input type="text" id="txt1" size="30" onkeyup="showResult(this.value)" />
<div id="livesearch"></div>
</form>type
</body>
</html>
Problem area below in bold. Code: function showResult(str){
if (str.length == 0)
{
document.getElementById("livesearch").innerHTML = "";
document.getElementById("livesearch").style.border = "0px";
}
var xmlhttp = getXMLHttpObject();
if (xmlhttp == null){
alert("Your browser does not support XML HTTP requests!");
return;
}
var url = "livesearch.php";
url = url + "?q=" + str;
url = url + "&sid="+Math.random();
xmlhttp.onreadystatechange=stateChanged ;
xmlhttp.open("GET", url, true);
xmlhttp.send(null);
}
function stateChanged(){
if (xmlhttp.readyState == 4){
alert("Never seems to hit a readystate==4");
document.getElementById("livesearch").innerhtml = xmlhttp.responseText;
document.getElementById("livesearch").style.border="1px solid #A5ACB2";
}
}
function getXMLHttpObject(){
//Current browsers
if (window.XMLHttpRequest){
return new XMLHttpRequest();
}
//For IE 5/6
if(window.ActiveXObject){
return new ActiveXObject("Microsoft.XMLHTTP");
}
else
{
return null;
}
}
My PHP file is just a simple echo statement to see that it works to that point. It doesn't. For whatever reason, it never seems to hit readyState ==4. It enters the function (I've checked with alerts), but the if statement never comes out to be true. I have no idea why. I've combed over the code for errors for a while now and I can't find anything. Any ideas? Would be much obliged. I have used this formula before, for some reason it isnt working properly. If the value is equal to 0 it will give an alert and return false. Then if you change the value of the drop down it won't let you submit. Does anyone see anything wrong? Code: <script type="text/javascript">
<!--
function validate_form ( )
{
valid = true;
if ( document.week_picks.blowout.value == "0" )
{
alert ( "Please Select a Blowout" );
}
return false;
}
//-->
</script>
Code: <form name="week_picks" method="post" action="confirm.php" onsubmit="return validate_form()"> <select id="blowout" name="blowout"> <option value="0">..</option> .... </select> Thanks for any help. I'm looking for code which does the following: When a visitor visits my website and clicks anywhere on the page, (regardless of where the mouse clicks) it will automatically redirect him to another site. I think an event listener might be a solution, but I'm not sure. Thanks a lot for any help on this If possible, I would like there to be a 2 second time delay before it does the redirection. I'm new to JavaScript, I just finished some basic things, like getAttribute, setAttribute, getElementByID etc. I understand that inline javascript isn't the best way to go, and all the JavaScript should go on an external JS file. I also know that you should be able to downgrade gracefully, allowing people whose browser do not/blocked javascript to still use the site. So I just want to do a simple go back function in an external javascript, however it's not exactly working. This is my JS code: Code: window.load = preparePage();
function preparePage(){
if (!document.getElementById()) return false;
if (!document.getElementByTagName()) return false;
var backDiv = document.getElementByID("back");
links.onclick = function(){
history.go(-1);
return false;
}
}
Here is my HTML code Code: <div class="back"> <a href="http://forum.thekks.net">Back</a> </div> Hi, I'm new to Javascript, so bear with me. I'm trying to use a script that replaces the contents of a div, based on div id's. I've gotten it to work how I want he http://www.sixnations.be/home1.html But can't get it to work here, and I'm not sure why: http://www.sixnations.be/menu.html Relevent code, Javascript: Code: function changeMenu(obj) {
if (obj == 'food') {
//alert('food');
var fd = document.getElementById('food');
fd.style.display = 'inline';
var fdi = document.getElementById('foodImages');
fdi.style.display = 'inline';
var dr = document.getElementById('drink');
dr.style.display = 'none';
var dri = document.getElementById('drinkImages');
dri.style.display = 'none';
}
else if (obj == 'drink') {
//alert('drink');
var fd = document.getElementById('food');
fd.style.display = 'none';
var fdi = document.getElementById('foodImages');
fdi.style.display = 'none';
var dr = document.getElementById('drink');
dr.style.display = 'inline';
var dri = document.getElementById('drinkImages');
dri.style.display = 'inline';
}

If this process fails, there is no child window, no redirection. the script below works fine in FireFox but in Chrome, if the process fails, the redirection still happens. I'm new to JS would appreciate your help many thanks Code: <script type="text/javascript">
function openwindow(){
testWindow = window.open("popup.php","interaction");
setTimeout(function() { testWindow.close(); },1000);
setTimeout(function() { window.location = "http://www.google.com"; },1000);
}
