I'm having an issue determining whether the mouse is increment or decrementing.
Code JavaScript:
_self.mousedown(function(e) {
var initialValue = parseInt($('#value').val());
var initialMouse = e.pageX;
[Code]....
As I move my mouse to the right, this returns true. When I move the mouse to the left, this still returns true; because the currentMouse value is still greater than the initialMouse value.
I've got an embedded system that uses a javascript-enabled browser as a
front end.
The input system consists of an encoder which generates + and - chars, and
a couple of keys that generate Tab and Shift-Tab for navigation.
Each field in the form is numerical, and has certain properties; for
example, one field represents %, and has a min of 0, a max of 100, and
increments of 1.
I need to come up with some javascript code that would take take those +
and - chars, and increment/decrement the field values so that the user can
'dial in' the value they need....
I just need to get a unique number dynamically at the end of the new object name (paItem) name but I get an error when i try to do it this way.

I am making a LOVE IT button using php and jquery and i have most of it working...
The button currently returns the value from the DB of 0 but when i click the button it wont save the incremented value to the DB.
see it here[URL]
my code is this
<?php
mysql_connect("localhost", "web183-loveit", "password") or die ("Error.");
mysql_select_db("web183-loveit") or die ("error");
$increase = "UPDATE results SET value=value+1 WHERE id=1;";

I need to make an HTML button whose value is "Times clicked: 0" and every time the user clicks it the value increments the number so it will say "Times clicked: 1" after clicked and so on. I don't know if a javascript function is the best way to do this, I know how to change the value on click but I don't know how to make it increment only the number
<INPUT NAME="myButton" TYPE="button" VALUE= " (I don't know what to put here) " onclick=increment()>
<script type="text/javascript">
function increment() {
document.myForm.myButton.value= (how do I make it increment?)
</script>
I'm kind of at a lose this is my first foray into using a multi-dimensional
array and I've run into a snag. for some reason the second dimension always
seems to end up being the last value of the second dimension of the array
ie: in the case below the conditionArray[[0][1]] always ends up being 6.0
where it should be 1.0. Code:
Simply put, I need to take a variable (The number '20' in this case) that is displayed by an input box on my web page and plug it into a function so that whenever I click on a button, the number in the input box will decrease by 1.
Seems simple enough, though for hours I've been going at it with no luck. Skipping the rest of my code - I currently have:

The entire code is a slot machine project that's supposed to be extremely simple where you hit the button and it spins 3 wheels, 3 of the same image and you win. Every spin takes $1, every win gives $13.
The majority of the code is already working, however for some reason I appear to be failing badly at getting the read out to show a decrement of $1 every time you push the button.
I've tried so many different ideas that I've found across w3schools, webdevelopersnotes, dave-reed, ect - and so far I haven't been able to get any of them to work correctly.
Last evening I ran across this script which I think will address a need I have; replacing my radio buttons with images. The one difference I have is that I need to use a different button image for each of the 5 buttons in my group.Unfortunately, the script dose not apply unique classnames within the generated mark-up so if I'm to use this I need to apply some sort of counting variable that increments and use this variable to append the classname with.Around line 52/53 of jquery.checkbox.js is

My requirement: Each time a visitor arrives at a specific webpage i want the main image on the page to be different, or more specifically, one of 6 images which will be shown in rotation. Solution: Set a cookie. Each time the visitor access the page read the cookie and display the corresponding image. Then increment the value and rewrite the cookie, so that next time they'll see the next image in sequence. NB: if the cookie does not exist (first timer) or is at 6, then the value is set to zero (and then incremented).
Problem: Can't get my coding to work. Specifically it just doesn't do anything - no error message, no cookie written. I'm a very novice scripter, as in I've cobbled the coding together from bits off the net that i think i've managed to grasp some kind of an understanding of. Very suck it and see - so far lots of sucking and no seeing!

Is there any way to determine the row & collumn number of a certain cell within a table?
I've looked at rowIndex and similar stuff, but I can not get it working. The info I found on this was minimal...
Any one have a way to determine the left pixel position of an element on a page (such as <input ...>, given a fixed value was not supplied originally. This needs to be done dynamically so several elements can be aligned by setting their css left values. Jquery is available if that is of any use.

View 3 Replies View RelatedIs there anyway using Javascript, one can determine whether or not the browser viewing the page supports a particular CSS property or value? For example, I know IE6 doesn't support the value of "fixed" for the "position" property, so is there anyway I can determine this with Javascript, without resorting to browser sniffing?

I was wondering if there was any method for determining the existance (or no existance) of a given DOM element using its Id.
My problem is the following :
I have some ajax stuff that does some crazy things to my original document well... errr... such as simply adding some new layers with a unique Id.
What I wanted to do, from another JS function that is triggered later on, was to check if theses layers were existing or not before populating them.
For example something like :
if (document.getElementById("blah").exists){
//populate the thingie !
}
var someObj = {} Is there something I use to determine that someObj is empty? It's still a typeof object but has no attributes.

After confirming that this statement has been available since FF2 (js engine 1.7) [URL] became curious as one determines their javascript engine in FF. IE has a way to inspect the jscript engine, ala [URL] but I couldn't find anything similar for FF. Feel free to list links for testing engines in other browsers,

I was wondering if the was any way to determine the state of the caps
lock key, on or off. Of course I can capture the key events and see whether the caps lock is pressed, but that does not help.
I have seen some example that looks at the characters entered in an
input field to determine if the caps lock is on, but I was wondering if
something is possible that is a bit more immediate to report the caps
lock state.
