I have some date calculations that add a time span to a date. The problem is, when I add a time span that is a whole number of days to a date, the result can be +/- 1 hour due to daylight savings. Is there anyway to disable this?
View 2 Repliesok im getting tired of looking for an answer and coming up short with
scripts that dont work. i have a application that uses GMT for all its
times and needs the clients timeoffset for showing the correct times
for everything. i use date.getTimezoneOffset() which works fine and
shows the daylight savings time correct value of -4 since im in eastern
standard time and its daylight savings time right now. well eastern
standard time is normally -5 and my dropdown populates with the -4
showing atlanta time. which will confuse the user and then they will
pick -5 eastern time which will make everything an hour off. i have a
disclaimer now, but i just want to know what the easiest way to display
the users time zone name useing the getTimezoneOffset() value. i
really want to be able to detect if the user has the adjust for
daylight savings checked for their machine.
Well I am facing this strange issue with javascript. Specifically on
the 26th October 2003, when I select any roomtype I get the rate 0 if
"In the Operating system, Time Zone is selected with "Automatically
adjust clocks with daylight saving changes". why does this happen,
please have a look at this page: Code:

I am just wondering whether that'sachievablewith jquery, and if so, how I might be able to implement this.

View 4 Replies View RelatedI have a wapper here, and I'm going crossed eyed trying to figure this one out. I have a form with Radio Buttons for my customers to purchase a customizable club program. I have 5 sections each of which cost a certain amount. Then I have another section that lets the user pick what duration they would like, 3, 6, 9 and 12 months. Each option has a certain % taken off the retail price. 5%, 10%, 15%, 20% depending on the duration option. All calculations are done on the fly as customers click the radio buttons. I do have it set up and working, only I have the duration listed as many times as my sections. I would like to have only one duration section. I'm not sure if this is done in java or HTML....

I need to calculate the total either with on_change or with a button

I got the following code running on a seperate page but how could I do it without forms? the page I wish to put it on page is one big form and therefore nested forms are a no no.
<script>
function calc() {
var inp = document.ccForm.inpt.value
var inp2 = document.ccForm.inpt2.value
var outp = 0
outp = inp * inp2
document.ccForm.outpt.value = outp
}
</SCRIPT>
<FORM ACTION="#" NAME="ccForm">
<INPUT TYPE=TEXT NAME="inpt" SIZE=10 VALUE="2.9" ONCHANGE="calc()">
<INPUT TYPE=TEXT NAME="inpt2" SIZE=10 VALUE="2.9" ONCHANGE="calc()">

I have a script with the following:
I need to do the following:
When the amount boc changes value, it must change the $credit amount and effect the $total_crt amount (ex. 10 + 10 in credit value - $total_crt value) So whenever the client chooses a new value from the select box, it must change it emidiately with javascript, but only send to the database once an update button is pressed.
Here is a quick example of my code:
I have a form which is used to calculate residential Floor Area Ratio (FAR). The form is structured into seven parts as follows:
Part A: Maximum FAR and Floor Area:
Part B: Gross Floor Area of the main floors of the main house:
Part C: Gross Floor Area of the basement or cellar:
Part D: Gross Floor Area of the attic:
Part E. Gross Floor Area of all accessory structures except detached garages: (including cabanas, guest houses, caretaker's cottages, pool houses, sheds, barns, or other structures except a detached garage)
Part F. Gross Floor Area of the garage: (not including basement garages)
Part G: Total Floor Area:
The Javascript involved in the calculations is as follows:

The problem is that nothing is happening when I press the calculation button.
What I would like to happen is to display a div element for each value in the array which displays the entered value from VenCost2, the current Margin %, and the result of VenCost2 * margin%. I want this to display on the same page and underneath the calculation button, preferably not having to reload the page.
I want to refresh the calculations on a form without submitting the form. I have tried two different JavaScript button codes, and I'm wondering if there is a reason for using one over the other, and if there is something else better for cross-browser use.
1) [ICODE] _doClick('$Refresh', this, '_self')
2) [ICODE] _doClick('$Refresh', this, null, null)

View 13 Replies View RelatedI'm looking for some help with something I have been developing over the last day or so. Basically, I have a form with some input boxes in it, and I am trying to use some javascript to do a calculation with these input boxes. The problem is that when I go to click on the "calculate" button nothing happens. The fields where the value should go to I have made visible instead of hidden to make sure that something is going there but nothing is appearing.
I've checked various parts of my syntax with online checkers and other javascript examples and I'm stuck as to what has gone wrong. If anyone can shed some light on the problem and possible solutions that would be awesome.

Edit: I have edited the code to remove/change the things that "Philip M" kindly pointed out were not needed and a bit of re-designing the page. I still can't get the javascript to put the answer value in the correct place on the click of the button. I'm under the impression it has something to do with the button rather than the javascript code but I might be wrong.
just wondering can i have a submit button to do some calculations before the whole form submits like this?
Code:
<form>
<options selected></options> <calcTotalSubmitButton>
<SubmitWholeForm>

how do i call the first submit button to submit what the user has entered, before submitting whole form?

I work for a small college and we were recently given permission to use a particular GPA calculator on their website. They sent us a javascript file, that I now have. I am trying to incorporate this into our website, but I don't really know much about javascript and I am having trouble making it work.
You can view the GPA calculator here to help clarify what I mean... If someone could just help point me in the right direction or if anyone know a site with tips that would be helpful to me..

I'm trying to use .load to get a simple web page. In the documentation for the .load function, I see that I can just return parts of page. I pass through the <body> element in order to just get the body, and not the headers of the html document, however in FireFox, it seems to still be returning all the headers. How can I use .load to ignore the headers.
