I would like to create a page that will refresh itself every 30 seconds or so, but I was hoping to be able to show an alert if the page has changed since last refresh. Is this possible?
View 2 Repliesi need to ask the user for details about a car, i will not know how many cars are going to be stored and therefore need an array i think. I need the function for asking the user and will need to repeat the code later in a menu. at this stage i just want to ask the user for input, store it in array and use an alert to check if it works?
<html>
<script>
// Purpose: Gather car information and store it in a datbase
// Ask user for REG info, CAR MAKE, car VIN
var CarDetails = {
RegNum:"",CarMake:"", CarVin:"";
}

I have this code in a function.

Alert 1 is to check if the program enters the function. And it does in all browsers. But when it comes to alert 2, Firefox does not execute the alert. So I assume there is something wrong with firefox executing the onreadystatechange. By the way this is the code for initAjaxObject()

Is it possible for Javascript to check if the visitor's browser has enabled the option to print background images, and if not to popup an alert?
View 1 Replies View RelatedWe've just been introduced to Javascript. I have a document where as it loads it gives an alert box. Upon clicking "OK" it brings up a header and an image and then another alert box stating that the page is now loaded. However, I need to change the background of the document by clicking on the "OK" button in the second alert box but can't figure out how to do that.
<style type="text/css">

How to change the color of the alert box in javascript ?

View 1 Replies View RelatedI'm writing a calculator script that will need user input (how much they pay on internet, phone or cable bill) and then multiply those numbers by a known rate and then show the customer the new number.
I have the math setup (working right now), and the script works to spit out the answers in an alert.
Instead of the alert (which is the only thing I can do correctly at this point), I need the script to give the answers for each bill and then a total answer at the bottom.
The script is here, it's all in the index file. [URL]
heres my code:
Code:
<script language="JavaScript">
var checkobj
function agreesubmit(el){[code]....
i need to make it like if the button is clicked and there the agreement checkbox is not checked.. it should give an alert that the alert is not checked.. i know that would require a if and else statement but i cant figure out how to do it
Okay so I have the code as below. When the page loads both alerts trigger as they should and all the code works. If I take out the first alert, the second one still triggers (so I know the code is reaching the bottom) but for some reason my .change() function stops working. Placing an alert just inside does not trigger so it must be something before the .change(). Firefox's error console shows no errors though.

How do you position an alert or prompt to anywhere on the screen. How do you change the font for the alert or prompt (i.e Hebrew)
View 3 Replies View Relatedanyone knows how to make alert box color change from normal
View 1 Replies View RelatedI hope this is relatively simple. I've looked around for the answer, but I thin think the search terms (update onchange event) are a bit too common...
document.getElementById("tester").innerHTML= "hello";
document.getElementById("tester").onmouseover = "alert('hello')";
You see I'm trying to change an event like I'd change a property. The first will change the text to hello. I'd like the second to change the onmouseover event to display a hello world alert... but it doesn't seem to do anything.

First of all, sorry for my other post, my first post didn't go through, I didn't get the chance to read the message, so posted again I've got this code:

I have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen()
{
var iChars = "`<>";
for (var i = 0; i < document.ipform.password.value.length; i++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..
I have been banging my head against the wall on this one. I have a drop down list menu that when a value is entered I have
"onChange="this.form.copy0002.value=this.value"
which takes the value of the drop down and places it into a text field in a different section. I also need it to check a box on the same line that corresponds with auto populated field. Is it possible to do this. I'm assuming it would be
" onChange="toggleChecked(0001check)" or some variation?
If you've used the Google Gmail spell checker you know that it
'changes' the text area to another type of control that lets them show
hyperlinks for the incorrect words. How does Google change the
textarea? And what do they change it to? I know it should be pretty
simple, I just have no clue because I'm fairly new to DHTML. Any
examples would be greatly appreciated.
In my effort as a javascript newbie i'm trying to create a nothing too special progress bar. I'm this far that the li's (bars) get a different color after another, but in the end it needs to change all bars back to the original class and start over. How do I accomplish this?

I would like to do something that:
Choose option:
To the option dates are assigned:
1 = from
09.10.2010
to 10
.10.2010
2 = from
09.11.2010
to 10
.12.2010
3 = from 24
.05.2010
to 29
.07.2010
And I want after choosing some option dates to change into the inputvalue.
1 2 3
From: do:
<!--
<select id="rate">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
From: <input type="text"id="from"value="03.10.2010" size="12" />
do: <input type="text" id="to"value="09.10.2010"size="11" />
<input type="submit" />
-->
I tried to do it with function ".val();" but value are keeping steady. It can be done any other jQuery function?
I just started using the grate validate plugin today and I can't really find an example of what I'm trying to customize...
Basically, I think it's confusing for a select element to change on focus instead of on change, meaning: the user forgets to select an option, the drop down is highlighted with some CSS, so use selects an option, but CSS error styling doesn't go away until the user clicks somewhere else on the page... A minor gripe, but I'm a big believer of the Steve Krug "don't make me think" school ;)
I'm still not quite clearly on how to implement own customizations of this plugin even after going through the docs...
