How To Detect Min / Max Variable Values
Oct 10, 2011
How to detect the smallest values the user inputs but does not explain how to detect already declared variables that have values in them and how to detect which of these declared variables has the smallest number.
For example:
double aA = 3.7;
double aB = 5.8;
double aC = 1.9;
double aD = 7.2;
double aMin;
// this is the variable I want the program to detect and stick
// the smallest variable into.
I want the code to detect the variable containing the smallest number and it has to be able to detect negative numbers as well.

I've been looking at Eli's object.watch [URL] script and I understand the idea of it and what it does but I'm so confused about how I actually use it in my script! Even if this seems quite obvious to most, I'm just not seeing it I might even be trying the wrong approach to it entirely and object.watch isn't what I actually need to be using!I've got my script here:
Code JavaScript:
<script type="text/javascript">
jQuery.fn.elementlocation = function() {
[code].....
Now as you can tell, the server load will be pretty high with the mouse move constantly calling data from the fetch.php page through AJAX. SO, what I'm trying to do is only call upon the AJAX when the variable "block" changes it's value. So I assume, I have to somewhere store a value, and then when the value changes check it with the stored value, but of course, the stored value will always change to the new value too since it's all determined by constantly changing variables? So how would I get it to only call the AJAX section when the block number changes?

I know this does not work, but hopefully you can see what I am trying to do. Only the first value is tested, but I want all of them to be.
[Code]...
Pretend there are like 10 more cases with more numbers with them. Currently this will only text to see if x is 0 or 42. How do I get it to test for the other numbers?

I've a picture gallery with the images stored as variables in a javascript file like this:
var a100image10 = new mypicture("album1/a100image10.jpg");
var a100image11 = new mypicture("album1/a100image11.jpg");
I've a "next" button to show those images (one by one) in a div with this code:
document.getElementById('image').innerHTML = "<img src=images/gallery/"+eval(album+"image"+next+".getPath()")+"></img>";
where the eval function returns the path of the pictures.This works fine! but in IE I get an error saying a100image12 not defined (and image13, image14, etc), because that image is not in the javascript file.So, how can I test in advance if a variable exists in the file?? Note that I take the name of the next picture based on the current one.I mean,I take the current picture from the div, lets say a100image10, I add one, and I try to look in the file for the variable a100image11.

I have a variable that contains Form Elements. So these elements can be eitther a :text either a :check box See code below:
var currentValue = $(targetedInput).val() ? currentValue = $(targetedInput).val() : currentValue =$(targetedInput).is(':checked')
I was hopping that this line of code would assign a different value to currentValue depending on what kind of object i have. My idea was that If the current Object is a check bot it doesn t have a val attribute..

How I would modify the following function to get it to check if a url variable is present and if so to add it into the string variable for the url.
If my url is index.php?make=Apolo then I need to get this added into the var queryString part of the function so that the ajax returns the correct values.

I am fairly new to coding HTML with Javascript. I am hitting my head onto the table because i cannot figure out how to pull the variable value out in a document.write statement. Basically, I am calling a function to give me a random number between 1-4. I use that randomNumber to attach to different .jpg, descriptions, and URL's. So far, i have only got the image to display, but unable to get the link and description to display. Basically, i am trying to diplsay random ads and links like the one at the top of this page.
p.s. I know I am getting the randomNumber out of my function becasue I can call a simple document.write(randomNumber) and it works. Substitute adDesc and adURL in place of randomNumber and I also get the description and link respectively.

I am having a problem with Netscape 7.01 & 7.02 not updating a
variable value in javascript. I have stepped though my code with a
debugger, and the values and code all look correct. This problem is
not happening in Netscape 7.1, but I really need it work at 7.0x
because many users use these browsers, and it would be a annoyance to
force them to update their browsers.
Is there a way in javascript to force the browser to update the
dynamic variables? I'm pretty sure this is a browser bug, but would
like to find a way around it with my own code.

Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.
Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.
The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.
So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?

I am writing a Javascript to sort and write out some stuff. PHP is not an option so I need to get this script working.
The problem arises when I want to make a link to the next page. (i.e. Like the link in google for the next 10 results)
I have <a href=# onclick=FUNCTION(VALUES)> written dynamically by the script.
It is written onto the document correctly, but the problem is, when the link is clicked, some seemingly random values are passed to the function.
I also have an invalid character error that arises when I pass the "whereVARquoted" variable into my function (code 2) which disappears when the variable is removed (code 1).
My code is below:
Code 1:
<script>
Code 2:

I have a list of products where they have minimum quantities in a hidden input. Some products have multiple colours, though the same minimum quantity and I'm trying to implement a jQuery check that entries made are at least equal to the minimum.
Blank or '0' entries are fine but if it's below the minimum quantity it should set to the minimum.
HTML:
Is there something obviously wrong with this? It isn't performing the minimum check and I'm really not sure why.

In part of my form, I have 3 inputs (one textarea and two text inputs),I am validating their value format using AJAX (each input triggers error message on its label in case format is wrong). Also I have one button, "NOT submit button" (type = button).Now, when clicking on the button it must enter the value of those three inputs in my database in case they are true then all inputs values must be cleared. In case AJAX validation is wrong and in case the user clicked on that button, the value of fields must kept as it is.
Actually I can not use submit button because I have it for the whole form and what I am taking about is a part of the form and it's not possible to make nested forms as I know it violates html rules. It's easy to make it if I am taking about submitting button as I can view session values on fields after submission in case ajax returns error.I can clear inputs from Javascript, but it will be cleared on both cases if AJAX validation true or wrong. Each input field has AJAX Error message that will be triggered when the input format is wrong.

I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?

I built my company's website and the content portion of the site uses
text with styles with relative values and the navigational part of the
site uses text with styles with absolute values. The purpose of this
was so that the end user could increase the size of the text on the
webpage and only the content portion of the page would scale or resize
but the navigation would not. This works as expected on a pc but the
entire page scales on a MAC. Does MAC not support text with styles the
same as pc so that the only scalable text is that with relative values
(ie: small, x-small, medium, large, etc)? Absolute values conist of
point sized text. Code:
