Multiplying Large Numbers

Apr 10, 2007

I would like to calculate factorial numbers that produce results of
say 100 digits. What is the best way of doing it in Javascript?
Can I define a variable and somehow have control on each of its digits
individually?

Can I multiply two relatively small numbers and determine that there
was a carry?

Calculating / Multiplying Form Fields (on Exit)?

Jul 16, 2009

This is probably very basic, but I don't think I'm searching the right terms to find what I need, I'm looking for an example code of how to do this.I have 3 columns (form fields below)

PRICE | ITEMS | Total

I want a user to be able to enter in a price and the amount of items so that when they leave one of those two fields, it will autocalculate and populate the "total" field. I also want the option for them to be able to fill out the total field alone, without having to enter "price" or "items". So basically 'total' has to be filled out either way, because I will then be doing calculations with that data.

Multiplying And Addition - Allow Users To Check One Or More Of The Checkboxes And Multiply It By A Quantity

Jan 30, 2009

I am having trouble making a website for a vacation rental I pieced this javascript code and form together with a simple goal in mind: -to have 3 checkboxes each with its unique variable

weeks: 2,000
weekends: 325
weekdays: 275

-to allow users to check one or more of the checkboxes, and multiply it by a quantity they choose (ie "I'd like to stay for two weeks (2 x 2,000=6,000) and one weekday (1 x 275=275)

-finally, to add up the totals at the end (6,000 + 275=6,275)

Calculate Field Values Using Javascript

Feb 26, 2006

Can someone explain how I can use javascript (I am assuming this is the best
way to do it) to add two field values together. I.e. field 1 plus field 2
equals field 3 (this is in a php form)

Also how can I set a field to be a value depending on what the user selects,
i.e. they may have eight items to select from and each one has a different
value.

The above javascript will then use that value to add to another field value
to give a me a total value....

Retrieving Form Values In Javascript

Sep 29, 2006

I am trying to create a form for authorised users to upload photos to
an image gallery. I'm attempting to perform simple validation of the
fields by ensuring the fields aren't empty and that the extensions are
right. However, I can't seem to access the actual values of the fields
to start with.

If I simplify my problem, can anyone tell me why this would work in a
Javascript alert:

alert(document.form.Photo1.value);
//This outputs 'D:/images/x.jpg'

but this won't:

var photonumber = "Photo" + 1;
alert(document.form.photonumber.value);
// I get "undefined"

The reason I'm doing this is because I'm looping through a finite set
of images and need to check each one is valid.

Is it because I'm not initialising the "photonumber" string correctly?

Javascript Variables Not Applying Values

Mar 20, 2007

i have the following snippet of javascript:

liChilds[x].onclick = function(){
toggleSubMenu(sub_menu_id, false);
return false;
}

That code happens within a loop, and sub_menu_id has a different value through each iteration of the loop. For example, if it loops 4 times, then there will be 4 onclick functions and sub_menu_id would change for each one. This should happen in theory, but instead, whichever item you click on, sub_menu_id takes the value of its last value in the loop. (4 in this example)

My question is, how do I make the function toggleSubMenu take the value of sub_menu_id at the time the on click function is created (i.e while looping) rather than taking the value of sub_menu_id when it is actually clicked.

Passing Dynamic Form Values To Javascript

May 26, 2007

I have a form that has been dynamically created from PHP. It is basically a calculator and the number of form elements as well as names of the elements can vary greatly.

I basically want to add a button that will open a new browser window with the form info being passed to it. Basically it will create a quotation for the customer that is suitable for printing.

The only way I know to do the popup window is with javascript (unless php can do it). I know how to access form elements with javascript if the form element exists, but given most of the elements may change, I do not know how to access them.

Creating Javascript Function To Swap Radio Values

Mar 1, 2006

i am having a problem creating a javascript function to swap my radio values based on the first set one.

i have a bunch of radio buttons on the page which are like this:

Code:
<input type="radio" name="add_id[1]" value="yes" CHECKED>Yes <input type="radio" name="add_id[1]" value="no">No
<input type="radio" name="add_id[2]" value="yes" CHECKED>Yes <input type="radio" name="add_id[2]" value="no">No

etc.... and each one is different, related to an input field, and as you can see it is a radio input array, and all radio inputs are named add_id[1], add_id[2], add_id[3] and so on i want a javascript function that will swap all the values of these radio buttons to whatever the first on is set to, either 'yes' or 'no' Code:

Sending Values From Server Side To Client Side Javascript

Jul 20, 2005

I have a Hyperlink within a String like below:

sSql = "SELECT DISTINCT " + "'Action' = '<center><a
href='+char(34)+'ChangeRequest.aspx?ID='+cast(Chan geRequest.ChangeRequest_ID
as nvarchar) +CHAR(34)+'>Open</a></center>',"

I want to invoke a Client side javascript function and pass the value
of the ID. How can I accomplish this such when a user clicks "Open" he
goes to a new window with the same ID.

I tried this but it does not work:
On Server side:
sSql = "SELECT DISTINCT " + "'Action' = '<center><a href= 'javascript:
NewWindow('+cast(ChangeRequest.ChangeRequest_ID as nvarchar)+
CHAR(34)+)'>Open</a></center>',"

On Client side:
function NewWindow(myID)
{
window.open("ChangeRequest.aspx?ID="+myID,"WindowName","width=500,height=600");
}
</script>

JQuery :: Checking Multiple Input Values Against Various Other Hidden Minimum Values

Jul 19, 2011

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.

Ajax ::Submit Inputs Values Using Normal Button / How To Keep And Clear Values

Apr 15, 2010

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.

Stylized Text With Absolute Values Vs. Relative Values And Scalability On A Mac

Sep 19, 2005

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:
