I am trying to write a script that will take a date of birth and another date and, if the person was over 75 years old on the createdDate, return "true" (otherwise return "false").
Unfortunately my code doesn't seem to return either 'true' or 'false'!
The code is:
var dateofBirth="30/10/1982";
var createdDate="01/12/2010";
var sd = dateofBirth.split('/');
var dob = new Date(sd[2],sd[1],sd[0]);

I want to create a link that a user can click which will create a popup
telling the user their ip address. I have:
var ip = new java.net.InetAddress.getLocalHost().toString();
alert("Your IP address is: " + ip.substring(ip.indexOf("/")+1))
but this does not seem to work. It says the ip is 127.0.0.1. Strangely,
this piece of code used to work but all of a sudden it doesn't for some
unknown reason. Can anyone tell me what's wrong with the above code?
I have two date fields (check in, check out) and "number of days"
field.
I want the script to calculate automatically the difference.
For example: I have defaults dates, and I want the script to put the
difference in "number of days" field. And if the user will change the
date, the number of days will change automatically.
I am using date of birth field in my application and i m taking date of birth in yyyy-mm-dd format.
I need to calculate age by using this date of birth and should show alert if age is less than 5 years.
I am having difficulty getting the following assignment to run properly:Many companies charge a shipping and handling charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling charge of $1.50 for any purchase that is less than or equal to $25.00.For any orders over $25.00, add 10% to the total purchase price for shipping and handling,but do not include the $1.50 minmum shipping and handling charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a $50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling charge of $5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box. Save the document as CalcShipping.html.This is what I have after working on it round and round for 4 hours yesterday:

I am writing a form and doing a bunch of calculations one of which is a percentage based on the value selected. I am returning a correct result for two of the values but for the other two I am not.The 'discount' value is what I am looking for. It should return as 0 for values of 1 but it is doing the math as though it is multiplying by 1. And again for the value of 6 it should be 10% but is taking the value as 4.6 or something.Code is below I've included all of it (sorry) for better ease of understanding the math that is happening:

View 3 Replies View RelatedI am writing a DHTML application which uses AJAX to show dialogue windows etc.. (all the bells and whistles).When I display a DHTML dialogue in the foreground, I use JS to create a div which is a "layer" in between the foreground and the background which essentially "darkens" the background and disables all background functionality. Forcing the user to take action in the dialogue.How do I get the total scrollable area of the page so I know how big to make the "dark" div?I have tried all of these:
document.body.scrollWidth

They all work in one browser or another, (I am testing in IE, FF and Opera) but none of them give me the correct values for the exact scrollable area of the page.
I need help in calculating a score from a row of drop-down values.
I need to use the onChange to tally the score as the user moves across
9 categories (with drop-down selection of 1-9 or N/A) multiplied by a
weighted score. The final column for each employee would be the
calculated score. I know how to accomplish this with vbscript but I
need it to process on the screen so the user can see the calculated
score as they make selections. Also the code needs to execute as many
times as there are employee rows.(loop) I don't know how to do this
with Javascript
Here's the VBscript with the variables involved
Var S1 = Category 1 Weighted score
Var S2 = Category 2 Weighted score
Var S3 = Category 3 Weighted score
Var S4 = Category 4 Weighted score
Var S5 = Category 5 Weighted score
Var S6 = Category 6 Weighted score
Var S7 = Category 7 Weighted score
Var S8 = Category 8 Weighted score
Var S9 = Category 9 Weighted score
D5 = 0.92
Var Q11 = Category 1 drop-down Value(1-9) * S1
Var Q22 = Category 2 drop-down Value(1-9) * S2
Var Q33 = Category 3 drop-down Value(1-9) * S3
Var Q44 = Category 4 drop-down Value(1-9) * S4
If (Category 5 Value = "N/A") THEN
Q55 = ' '
Else
Var Q55 = Category 5 drop-down Value(1-9 or N/A) * S5
End If
Var Q66 = Category 6 drop-down Value(1-9) * S6
Var Q77 = Category 7 drop-down Value(1-9) * S7
Var Q88 = Category 8 drop-down Value(1-9) * S8
Var Q99 = Category 9 drop-down Value(1-9) * S9
If (Category 5 = "N/A") THEN
Var FinalScore = round(((Q11 + Q22 + Q33 + Q44 + Q66 + Q77 + Q88 + Q99)
/ D5),2)
else
Var FinalScore = round((Q11 + Q22 + Q33 + Q44 + Q55 + Q66 + Q77 + Q88 +
Q99),2)
end if

I'm a newbie to javascript and I made this script
<script>
var num = parseInt(prompt("Enter the number of integers to follow"));
var sum = 0;
for (i = 0; i < num; i++){
sum += parseInt(prompt("Enter a number"));
}
if (isNaN(num)) {
alert("Invalid");
} else {
if (sum < 0) {
document.writeln("The sum is 0 and the average is 0");
} else {
document.writeln("The sum is " + sum + " and the average is " + sum/num);
}
}
</script>
The scenario : Create in javascript that will read a series of integers at the terminal. The first integer is special, as it indicates how many more integers will follow. Your javascript is to calculate the sum and average of the integers, excluding the first integer, and display these values to the screen. If the total is not greater than 0 then display "The sum is 0 and the average is 0". Did I write the script correctly? am I missing anything that a dumb person might do? for example the person might type in letters instead of numbers.

I am working on outlet pages of an online store.There are 4 products displayed on each row.On that store, products are displayed with images,product name, model no., price and buttons.For some products, the name is longer, for some price is longer.I am using <td> for displaying each information.The problem is - the height of the name's <td> and price's <td> are different for different products.I want a JS code which can detect the biggest height (for each row separately) from both the above td's separately and assign the maximum height to the corresponding 3 td's of that row.This should be done for each row separately.note : I an right now using this code - But it takes the height of both td's for 1st product only and assign it to all the products.
