Conditional BeforeUnload
Oct 28, 2003
Essentially, I would like the user to be prompted that application has not been completed on back, close etc. I however do not want the user to be prompted if they have completed the application.
I have a function on submit where I plan to set the flag to true.
I would expect something like the following but it doesnt work for me?
function unloadMess()
{
mess = "Leaving this page without submitting the application form will clear DOB entries. Do you wish to leave the application form?"
return mess;
}
function setBunload(on)
{
window.onbeforeunload = (on) ? unloadMess : true ;
}
if (flag = "N") // Application form has not been submitted.
{
setBunload(true);
}
else
{
setBunload(false);
}
Any Ideas?

function checkBrowser(){
var IE = document.all?true:false
if(!IE){
window.onbeforeunload = function() { return 'Do you want to quit?' }
}
else{
alert('You're using IE');
}}
The body has onload="checkBrowser();", and on IE it does what I intended, but on a browser other than IE, the window.onbeforeunload does not function as I want it to.

Is there anybody who knows were to find a javascript that does the trick
of conditional pulldowns (3).
Here is what i am looking for:
When you select an item from the first pulldown, the second pulldown
gets populated with the children of the item you choose. Then, when you
select an item from the newly populated second pulldown, the third
puldown gets populated.

i have the following regex:
(s*{s*(<?)s*(>?)s*}s*)
this needs to be able to match a string and make the following replacements:
if the string matches without < or >, replace the match with a space, a replacement string, and another space. if < matches also, do not add the left space. if > matches, do not add the right space. if < and > match, do not add the beginning or ending space
Old {} String => Old Replacement String
Old {<} String => OldReplacement String
Old {>} String => Old ReplacementString
Old {<>} String => OldReplacementString
this will have to be done a LOT of times, so efficiency is very important the answer in php is below. can anyone help me figure out how to do it in javascript? PHP Code:

I just wrote the following script for something I'm working on:
<html>
<head>
<script type="text/javascript">
function KP_growit(subject,widthto,heightto) {
var target = document.getElementById(subject);
var tweenit = setInterval(grower,10);
function grower() {
(parseInt(target.style.width) < widthto)? target.style.width =
(parseInt(target.style.width) + 10) + "px";
(parseInt(target.style.height) < heightto)? target.style.height =
(parseInt(target.style.height) + 10) + "px";
(parseInt(target.style.width) == widthto && parseInt(target.style.height)
== heightto)? clearInterval(tweenit);
}
}
</script>
</head>
<body>
<div id="bluebox" style="position:absolute; left:173px; top:48px;
width:100px; height:80px; z-index:1; background-color:#99CCFF;"></div>
<div><a href="#" onClick="KP_growit('bluebox',400,300); return false;">grow
it</a></div>
</body>
</html>
I noticed that the script does not work because of the conditional
operators; however it DOES work when using the if...else format. Why is
this?

I am making a form where you can either upload images or link images and upload a video. The problem is that I want a or situation. I made javascript function that when you click one of the 3 images it will add in one item this could be a image link or uploaded image or a video. There is only one function that runs and inside that function has if statements to figure out which one image was clicked.
I have 3 images one is for image links one for uploading images and one for uploading video. the problem is that I want the user to append only image links and uploaded image or uploaded video.
I am only allowing 8 images to be uploaded or 1 video. This is a form that submits a message with either of the above but I only want to append only the images or the video but not both.

This is the loop I'm trying to use to check for bullets hitting rocks. the function worked if I used actual numbers instead of the j variable, but I wanted to loop through all the rocks.Can anyone see why the inner function loses the j index and says asteroids[j] is undefined? the hit test is removing the bullets! it's working! the asteroids[j] was used in the hit test!

I'm trying to create a test using Javascript. Actually, I did this in PHP, but we need to put it a server that does nor run it, I think I can convert it to Javascript. I hope it'll be work as in PHP somehow. Test will be composed of 15 questions and each question has either "Yes" or "No" as answer. And, I use radio buttons here for answers. By the way, there will be more than one radio groups. Now, I want to check the value of clicked radio button in each group and use an if-statement to determine if it's correct. And, if it's correct, I want to increment a variable by 1. Finally, by the resulted variable incremented for each question in the test, I want to use another if-statement to show specific result message for and interval of that variable.

I am trying to create a conditional comment scenario that is based on a web address. I am working with an ecommerce site that I want to put a nav menu promotion on all the pages except the home page. The system we are using only allows a post promotion to ALL or one specified URL.
I have tried everything I can think of to create a URL condition based comment but nothing has worked. I tried modifying the code below to change the if output to a variable comment tag and then write the variable further in the script with a document.write.
<SCRIPT LANGUAGE="JavaScript">
<!--
url=location.href
if (url=="http://www.sitename.com") {alert("Welcome To sitename")}
else {alert("welcome")};
// -->

With the exception of the boolean variable, I'm wondering if it's possible to combine the bottom 2 into one statement, so s exists in the current scope
Code:
var boolean = (true or false)
var s;
boolean ? s = 40 : s = 80;

I have a very simple script that generates a prompt window. Instead of using a default text, I have left the text field empty. However, I would like a default message to display in the pop up window if the user does not enter a value in the prompt box before clicking okay. I tried adding a conditional statement but the default text does not write in the pop up window.
Here is the code:
Code:
function promptBox(){
var message = prompt("Who is your favorite Hollywood Star?", "");
newWindow = window.open('','','width=800,height=600');
newWindow.document.write(message);
newWindow.focus();
if ((prompt) == null);
document.write("No Value Entered");
}

I want to create a conditional form using cookies to restore the state of a radio button if wrong data is entered into one of the textfields on my website. A tutorial on Onextrapixel explains something similar and I was trying to modify it according to my needs.
The following code shows the script I am using. I tried to .hide() or .show() the specific content according to which radio button is clicked. Hiding the right content works without any problem if I disable the cookie stuff.

I am building an application where more than one device can change settings on a webserver.Imagine using 2 smartphones. If a button on smartphone#1 is being pressed by a user, then on the webserver the status changes from 0 -> 1. I need both smartphone#1 and smartphone#2 to change from 0->1 and vice-versa so that the user knows the current value of the status.How can I accomplish this? Meaning, if I want to make a toggle switch.I read on the website:The first option will be styled as the "on" state switch and the second will be styled as the "off" state so write your options in the correct order.[code]My first guess is to create a function in the <head> in script, with one for the on and one for the off state.Depending on the current value I either load one of the two codes in the <body> section.The script in the <head> decides.

I have a form with 5 options for destinations. Each destination has several hotel choices. Each of the options has the same variable name that is passed to the booking engine at the other end. The problem is that it's passing 4 blank and 1 populated field for the same variable. How to strip the blank ones from the string and/or pass one populated field?
<select style="display: none;" id="resort_czm" class="c4" size="1" name="selectedHotelId">
<option value="" selected="selected">Please select an Iberostar Resort</option>
<option value="211040">Iberostar Paraiso del Mar</option>
<option value="213046">Iberostar Grand Hotel Paraiso</option>

The red part of the code below doesn't work correctly, but I hope it shows what I want.
Code:
<html><body>
<div id="container" style="float:left;">
my<br> dynamic<br> contents
</div>
<script type=text/javascript>
var container = document.getElementById('container');
var containerHeight = container.clientHeight;
if (containerHeight >= 100) {
dispaly("big sideBanner");
} else if (containerHeight > 50 && containerHeight < 100) {
display("middle sideBanner");
} else {
display("small sideBanner");
}
</script></body></html>
I like to display "big sideBanner" on the webpage if containerHeight is 100 or containerHeight is more than 100 and "middle sideBanner" if containerHeight is more than 50 and containerHeight is less than 100 and "small Banner" if containerHeight is less than 50. How can I make it work?

I'd like to ask if it is possible to use conditional operators
var = condition ? var1 : var 2
To do the same job as the if-else statements I wrote in red below:
<p id="text">change text colour</p>
<br />
<a onclick="allsorting();">sort in both ascending & descending orders</a>
<div></div>
<script>
/* if & else */
function changetext(){
document.getElementById('text').onclick = function (){
swapcolour(this);
}}
function swapcolour(text){
if(text.style.color == 'black'){
text.style.color = 'red';
} else {text.style.color = 'black'}
} window.onload = changetext;
</script>

I am trying to set a link on our Intranet server to another onsite
system.
I want to send people to a page, that performs a check to see if the
website on the other server is ONLINE. If not then display a message
along the lines of SORRY PLEASE TRY LATER.
I have done some searching and it seems that I might be able to use the
onerror part within javascript.

I'm trying to write a modal login script which I borrowed from the SimpleModal site. Unfortunately, I'm running into a very frustrating problem.
When the user types in a valid login/password combo, the PHP function do-login.php echos back "OK". That being said, here's a snippet of my jQuery code:
$.ajax({
type: "POST",
url: "do-login.php",
data: str,
[Code].....
The do-login.php script DOES echo back "OK"- I verified that with Firebug. But even though it echos back "OK", it goes to the 'else' clause.
I tried using return instead of echo but that didn't help either.
