JavaScript - New Coder: This Script Doesn't Work Consistently
Hi,
I am a new poster here and new to javascript as well. I made a script in which if a user enters the correct coupon code, he will be directed to a confirmation page. If not an alert box will say the coupon code was wrong. It sounded simple enough and it worked for sometime. Here is what the code looks like: Code: //in the head section
function isGood(elem, helperMsg){
var pass = "x1y2";
if(elem.value==pass){
location.href="./couponbuy.html";
return true;}
else{
alert(helperMsg);
elem.focus();
return false;}
}
//in the body section
<form>
Please Enter Coupon Code: <input type='text' id='code'/>
<input type='button' onclick="isGood(document.getElementById('code'), 'Please enter a valid coupon code')" value='Enter' />
</form>
As I mentioned, it was working originally, but now it only works when I change the variable 'pass' to something different. I want to be able to keep the variable the same. I don't understand what exactly is going on here. I appreciate any and all help. Thanks. Similar Tutorialshello... script doesn't work.. it does work in IE but not in another browser like mozilla,opera & safari? what should I do?.. Code: //Current HTML of page

Can someone see my error? I'm a bit rusty at my javascript. Hi all, firstly i'm not a coder but i am capable of doing as instructed. I have some script that when used in conjunction with a button highlights all the text between 2 tags to make it easier for copying, it works great in IE but doesn't work in firefox, could someone help please? Here's the script and the button is below. Code: <script type="text/javascript">
function selectCode(a)
{
// Get ID of code block
var e = a.parentNode.parentNode.getElementsByTagName('CODE')[0];
// Not IE
if (window.getSelection)
{
var s = window.getSelection();
// Safari
if (s.setBaseAndExtent)
{
s.setBaseAndExtent(e, 0, e, e.innerText.length - 1);
}
// Firefox and Opera
else
{
var r = document.createRange();
r.selectNodeContents(e);
s.removeAllRanges();
s.addRange(r);
}
}
// Some older browsers
else if (document.getSelection)
{
var s = document.getSelection();
var r = document.createRange();
r.selectNodeContents(e);

To sum up, the code detects an image on a server and checks its size. If it's size is less than zero, then "Off" appears in a form input field. Otherwise, "On" appears in the field. This code is being used in a smartphone to test for Internet connection. Code: <form id="formConnection">

I have a few tabs on my website. They're each set to the corresponding id in the JS file. It's supposed to add #tab-1 to the end of the URL in the users browser when it's clicked. For example, when a user is at mypage.com and they click on the tab, it ads mypage.com/#tab-1 to the end. How come it doesn't do what I want when I click it though? Here's an example of how it's setup. HTML: <a href="#tab-1" id="tab1">Text</a> JavaScript: document.getElementById("tab1").onclick = function(){ this.href += "#tab-1"; } This is a script which has a window slide down on the page and a user can choose yes/no to continue. It works in all browsers other than IE...any help please? If you need more info, please let me know.

It should make the first blue, second red, and third yellow yes? Hi! I'm new to JavaScript and I've done some small adjustments to my clients site, but it won't show properly in IE (the shadowbox js at least.). I thought js was accepted in all newer browsers. Do you have a quick fix or idea on why it doesn't work? You can view source on my site, I use mootools, and shadowbox/corners and rightclick blocker. Is it generally a 'bad thing' to use js in webpages I want everyone to view in the same way? I tried the same effects with CSS but it's not supported in the same way corss-browser, unfortunately. The 'no selection' CSS class I have on the site is also not accepted in IE. It's very annoying! http://santinacrolla.ihaarr.com/p thank you in advance! I've got a form textarea on my site, which after being submitted is stripped by my php file. Then my javascript kicks in and does some analysis of the entered text. However everytime the user entered a hard return within the textarea my javascript gives me an error 'tekenreeks niet afgesloten' which means something like 'string is not closed'. Therefore I decided to replace all occurences of chr(10) and chr(13) with ok2 (just some random characters), I did this with php which worked fine, and I didn't get the javascript error. However I need to reshow the entered text (original) to the user, so I need to restore the old values. I tried Code: result.waarde.replace('ok2', 'chr(13)');
but it doesn't work, as it still displays ok2. I'm no expert in javascript, but how can I replace those characters by the hard returns? Oh yeah I'll show some more coding, perhaps the error can be found the Code: result.waarde.replace('mdw', 'chr(13)');container.innerHTML = result.waarde;
and in my html: Code: <div id='waarde' style="width:500px;"></div> Below is code using the onmouseover event, but it doesn't work. The only thing that appears in the status bar is the URL. What am I doing wrong? Code: <a href="http://codingforums.com" onmouseover="window.status='This is an OnMouseOver event'; return true" onmouseout="window.status=' '; return true">Put your mouse here to see status info change at bottom.</a> Heya, I wrote the following page in a day or two (please don't mind the layout). Everything seems to work excellent, apart from in Firefox (FF) in which it doesn't seem to work at all. None of the other browsers have any trouble with it. I'm pretty new to Javascript (everything you see in the source code is pretty much all I know) and I have absolutely no idea why it doesn't work in Firefox. The page in question could be found [link has been removed]. It's all there is to it. So yeah, how to actually make this work in FF? Thanks a whole bunch in advance! Much appreciated. It can be found right he http://arkdesigns.ca/AttilaKomaromiJavaCalculator.htm I have javascript enabled on my browsers but it still doesn't work.

Ive searched on this board but cant find out why this doesn't work. Code: <script type="text/javascript">
function showSelected(val)
if (val == "Nil")
{
document.getElementById('JustText').innerHTML='hi'
}
else
{
document.getElementById('selectedResult').innerHTML="<a href='mailto:" + val + "'>" + val + "</a><p>"
}
</script>
Hi, I'm trying to mirror two textboxes with the following: Code: <form>
<input type="text" id="0" name="tb1[]" onkeyup="document.getElementsByName('tb2[]')[this.id].setAttribute('value',this.value)">
<input type="text" id="0" name="tb2[]" onkeyup="document.getElementsByName('tb1[]')[this.id].setAttribute('value',this.value)">
</form>
If I start by picking the first box and typing it appears automatically in the second textbox. It works the same if if i start by picking the second box. However after entering text into one of the textboxes and having it mirrored, if I select the other textbox and make a change it isn't mirrored. Any suggestions? Thanks! I'm having one of those moments right now. Can someone explain why the following alerts "undefined" instead of "George"? Code: function test(){
this.worker='George'
}
test.sayname=function(){
alert(this.worker)
}
test.sayname() //alerts "undefined"
I know I can get it to alert "George" by instantiating test(), but I thought the above should work even without doing that. Please see URL: http://caspca.org/indexticker.htm The ticker below the navbar works fine in FF and Safari, does not work in IE8 (and mostly likely other IE version as well). In IE, the live page will not even load; will load locally but the ticker doesn't work (remains static). Here is the .js: Code: TICKER_CONTENT = document.getElementById("TICKER").innerHTML;
TICKER_RIGHTTOLEFT = false;
TICKER_SPEED = 1;
TICKER_STYLE = "font-family:Arial; font-size:12px; color:#444444";
TICKER_PAUSED = false;
ticker_start();
function ticker_start() {
var tickerSupported = false;
TICKER_WIDTH = document.getElementById("TICKER").style.width;
var img = "<img src=ticker_space.gif width="+TICKER_WIDTH+" height=0>";
// Firefox
if (navigator.userAgent.indexOf("Firefox")!=-1 || navigator.userAgent.indexOf("Safari")!=-1) {
document.getElementById("TICKER").innerHTML = "<TABLE cellspacing='0' cellpadding='0' width='100%'><TR><TD nowrap='nowrap'>"+img+"<SPAN style='"+TICKER_STYLE+"' ID='TICKER_BODY' width='100%'> </SPAN>"+img+"</TD></TR></TABLE>";
tickerSupported = true;
}
// IE
if (navigator.userAgent.indexOf("MSIE")!=-1 && navigator.userAgent.indexOf("Opera")==-1) {
document.getElementById("TICKER").innerHTML = "<DIV nowrap='nowrap' style='width:100%;'>"+img+"<SPAN style='"+TICKER_STYLE+"' ID='TICKER_BODY' width='100%'></SPAN>"+img+"</DIV>";
tickerSupported = true;
}
if(!tickerSupported) document.getElementById("TICKER").outerHTML = ""; else {
document.getElementById("TICKER").scrollLeft = TICKER_RIGHTTOLEFT ? document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth : 0;
document.getElementById("TICKER_BODY").innerHTML = TICKER_CONTENT;
document.getElementById("TICKER").style.display="block";
TICKER_tick();
}
}
function TICKER_tick() {
if(!TICKER_PAUSED) document.getElementById("TICKER").scrollLeft += TICKER_SPEED * (TICKER_RIGHTTOLEFT ? -1 : 1);
if(TICKER_RIGHTTOLEFT && document.getElementById("TICKER").scrollLeft <= 0) document.getElementById("TICKER").scrollLeft = document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth;
if(!TICKER_RIGHTTOLEFT && document.getElementById("TICKER").scrollLeft >= document.getElementById("TICKER").scrollWidth - document.getElementById("TICKER").offsetWidth) document.getElementById("TICKER").scrollLeft = 0;
window.setTimeout("TICKER_tick()", 30);
Any help to fix is greatly appreciated. Thank you. John Hello, I'm new to javascript and html5. I've been having problems with some simple(?) lines of code. Code: var ctex;
var totalX = 400;
var totalY = 300;
var racpad = new Image();
racpad.src = 'Imgs/paddle.gif';
var brixadow = new Image();
brixadow.src = 'Imgs/brickLight.gif';
function initCnv()
{
canvas = document.getElementById('canvas01');
ctex = canvas.getContext('2d');
AppStep();
}
function clearcv(x)
{
ctex.clearRect(0, 0, totalX, totalY);
ctex.fillStyle = x;
ctex.beginPath();
ctex.rect(0, 0, totalX, totalY);
ctex.closePath();
ctex.fill();
}
function AppStep()
{
clearcv('black');
ctex.drawImage(racpad, totalX/2, totalY-50);
}
What I'm trying to do is to simply turn the canvas black and show a small gif on it. Upon executing initCnv(), the canvas turns black as it should, while the sprite image doesn't show up at all. I can't figure out what's going on, I scoured the code for syntax errors, even tried other image formats but to no avail. Image paths are also correct. Maybe the problem's an extremely noobish one, but I still couldn't get a clue, so I thought I'd ask for help around here. Thanks for your time! Hi, doing form validation at college just now.
