I have a small javascript app that lets the user enter in a name and a mark, then store it in a cookie. This works fine. I need it to now take the numbers from the cookie and calculate the mean and standard deviation.
Code is this

How do I create a cookie for storing a random number in it.
View 1 Replies View RelatedCan I make a list of hyperlinks that users can customize and save as a cookie by clicking a button and automatically retrieve the cookie so it remembers their list next time? This is kind of what I want to do:

I am making a sort of text based game (Just a hobby) I like to do that sort of thing. So, anyway, considering all I can really do is code HTML, and very, very light javascript, I kinda need some help.
I basicly know how to do everything except affect & Use the cookies. So what I need to do with them is to
#1.) Have a code to change the cookie number, say... on the click of a button.
#2.) Have a code where it only displays certain text if the cookie is a certain number.
I cant code JS and have no idea how hard/easy this is.
If it is insanely hard & needs a master coder, just tell me and ill take it off. I dont want to be wasting anyones time.
I need to modify the script showed at: [URL]
Right now it allows entering "numbers only", I need it so that it allows numbers and alphabets only, no special characters or spaces.
And yes, one more question, does the first part of the code need to be added in the <head> of the document or <body> ?
The code at the above URL is as follows:
<script type="text/javascript">
// initialise variable to save cc input string
var cc_number_saved = "";
</script>

I have an embedded system with a web interface. One of the web pages
has a small JavaScript program that, when run on IE6, always displays
the message that cookies need to be enabled:
if (document.cookie.indexOf('asm_session') == -1)
{
document.cookie = 'asm_session=0'
if (document.cookie.indexOf('asm_session') == -1)
{
document.write("Advanced System Management access requires
cookies to be enabled."+'<br><br>');
}
}
This problem only occurs with IE6, not Mozilla. It also only happens
on some of the embedded systems, but this problem exists for everyone
running IE6.
The problem isn't limited to the Javascript code, either. On another
web page from this embedded system, a cookie is set the normal way,
via the HTTP header. This cookie is also rejected.
When I display any page that attempts to set a cookie, IE6 displays
the blocked icon and says that cookies on that URL are blocked.
However, I have set all privacy and cookie options to their most
permissive. I've spent the past hour changing every option I can find
that's even remotely related to cookies and privacy, and nothing
changes. Does anyone have any idea what's going on?
In my web application we are able to store large data in the browser
cookie keeping in mind the limit of 300 cookies per cookie file, 20
keys per cookie per domain and 4KB max size of each cookie. We are
unable to retreive this large amount of data immediately after storing
through document.cookie in IE browser (The same works fine in
Netscape).
Is there any limit on the size of the data that can be retreived using
document.cookie in IE browser? Could you please suggest a solution to
this problem I am facing.
I am trying to set a cookie in my cookie directory but this is not working.
document.cookie = "username=John;
expires=15/02/2015 00:00:00";
I am writing a script and everything works fine, except when I calculate my figure i want to display only 2 decimal points.
ie. 10 = 10.00

I have no idea on how to do this and I cannot use Cold Fusion.
Is there a built in JS Function?
I'm having difficulties arithmetically manipulating form element values.
I've entered data into the form, and I fetch them using a js, as:
p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);
Then I add these as follows:
scoreLeft = Number(scoreLeft + p&Left + ...... +);
This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?

I'm using a forLoop to generate 10 random numbers, how would I go about added them all together? code...
View 3 Replies View RelatedHow can you join two numbers together in javascript, like you would join two strings?For example, if you have two variables, with 1 stored in each, how can I join them together, so I get 11, instead of 2?
View 2 Replies View RelatedAnother quick question. I have the script to add each field up I need, but if the ending 0 after a decimal is present it doesnt show. How do I keep the leading zero and how do I keep just 2 digits after the decimal?
For example:
1 + 1.50 = 2.50
But javascript displays it as 2.5
Now sometimes when I do math I get:
2.3454545
In this case I just want 2.34. So if there is a ending zero I want to keep it, and if there is more than 2 numbers after the decimal I want to cut the rest off and leave the 2 there.
iw ant to have a function so that user can only enter numbers in the text box and + ( only once in the beggininging). if user wants to add + he can only enter + once as the first character like +123 or 123 bt cannot enter 1+2 or 123+ or +123+

My assignment for my programming class is to create a script using JavaScript that asks a user to enter a number in a pop up dialog box on their browser, and then tell them if they entered an odd or an even number. This is what I have come up with so far, whenever I test it on a browser it says that every number is even.
