JavaScript - Can I Divide 2 Numbers Then A 3rd Number By The Result
I want to build a web form that will allow users to enter 3 different numbers and get a result. The answer is arrived at by the following. Enter 3 variable A, B, and C. Then A / B = D. Then C / D = the Answer.
Is there a way to set that up as a single click script? Everything I have tried has failed hard. Similar TutorialsHi, I have what I thought was a fairly simple problem that I would be able to solve on my own, but the code I have found is just too complicated for me to understand, so id appreciate any help. I think what i have is similar to the knapsack problem, but I have a really simple version of it. http://www.ms.unimelb.edu.au/~moshe/...psack.html#def Say I have a relatively small array of numbers: 2, 2, 3, 3, 4, 4, 5, 5, 5, 6, 7, 8, 9, 10. I just need to verify true or false if a combination of these numbers will add up to 21. The numbers will obviously be changing, ( and in array size), i guess i could just use if statements but it would be stupid and go on for ages. Could anyone point me in the direction of some simple code, or easy to understand way to go about this problem? Thanks Noob here! I'm doing a little project where i need to take a number (lets say 6), and then I need to find out witch numbers 6 can divided with that equals to a whole number. Any ideas how i can do that? This is what i got in my mind so far: myNum/num === wholeNumber I then need a variable "num" that count all whole numbers from 0 to myNum and a variable "wholeNumber" that works as all whole numbers from 0 to myNum. I really hope you can help me out, thanks Hello, Could someone help me with this problem? I'd like the posted result to be a number with two decimals. I know how to make this normally but not with this kind of script. Thanks very much in advance! Code: <html>

This code works to show divide with id "it" when select option "it" is chosen and it shows divide "de" when option "de" is chosen. Problem: it will not show the nested divides inside the "it" and "de" divides. It only shows the <p></p> tags. Does someone know how I can get it to show the divides inside the main divide as well? Thanks in advance for your help. Head Code: function showstuff(divID)

I have a simple JavaScript stopwatch that displays the time using an html form with start/reset and clear buttons. Basically I'm making a speed calculator that converts seconds into MPH. All I need it to do is divide whatever the amount of seconds are by 40.91. So instead of it displaying the seconds being counted up (i.e. 2 seconds, would displayed as 20.455 MPH). Does that make sense? JavaScript is not my strong suit, and It's got me stumped. JavaScript: Code: var t=[0, 0, 0, 0, 0, 0, 0, 1];
function ss()
{
t[t[2]]=(new Date()).valueOf();
t[2]=1-t[2];
if (0==t[2])
{
clearInterval(t[4]);
t[3]+=t[1]-t[0];
t[4]=t[1]=t[0]=0;
disp();
}
else
{
t[4]=setInterval(disp, 43);
}
}
function r()
{
if (t[2]) ss();
t[4]=t[3]=t[2]=t[1]=t[0]=0;
disp();
t[7]=1;
}
function disp()
{
if (t[2]) t[1]=(new Date()).valueOf();
t[6].value=format(t[3]+t[1]-t[0]);
}
function format(ms)
{
var d=new Date(ms+t[5]).toString()
.replace(/.*([0-9][0-9]:[0-9][0-9]:[0-9][0-9]).*/, '$1');
var x=String(ms%1000);
while (x.length<3) x='0'+x;
d+='.'+x;
return d;
}
function load()
{
t[5]=new Date(1970, 1, 1, 0, 0, 0, 0).valueOf();
t[6]=document.getElementById('disp');
disp();
}
HTML form: Code: <input type='text' id='disp' maxlength=12 readonly /> <button type='button' onclick='ss()' id='butt' data-inline="true">Start/Stop</button> <button type='button' onclick='r()' id='butt2' data-inline="true">Reset</button> Any help is greatly appreciated!!! I have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function: 1: I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100. Does any one know how to code this in my function below in javascript: Code: function insertQuestion(form)
{
var row = document.createElement("tr");
var cell, input;
cell = document.createElement("td");
cell.className = "weight";
input = document.createElement("input");
input.name = "weight_" + qnum;
input.onkeypress = "return isNumberKey(event)";
cell.appendChild(input);
row.appendChild(cell);
}
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689 .toFixed ( 2 ) ==> "15.24" So does it convert the number into string? I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
say cutcost2 is 10 and qty is 25 Code: document.profile_quote.cuttotal.value = eval(document.profile_quote.cutcost2.value + document.profile_quote.qty.value) .toFixed(2) the output i get is 1025 rather than 35. what have i got wrong? thanks Hay! I have a silly question, I have a row of numbers, 1 to 250. The numbers are all in one horizantal line. But I want to use a <br> after every 10 numbers. I tried: if(i % 10) { document.write("<br>"); } This is how I wanted to be: 1, 2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, Does any one know how can I achieve this I'm still a noob. I'm trying to teach myself Javascript to prepare for it next term. I asked earlier how to add together the numbers 1-10 in a loop. Now I'm wondering how can I change the 10 to be a valuable I input. Basically I want to be able to enter a number on the page or in a message box then I want the code to add all the numbers from 1- the number I enter. The code I got from my previous thread is he Code: <html>
<head>
<script type="text/javascript">
var varX = user input;
function sum() {
var varX = user input;
for(varY = 1; varY<=10; varY++) {
varX = varX + varY;
}
return varX;
}
var resultat = sum();
alert(resultat); // show message box with result
</script>
</head>
<body>

This of course is easy in principle - I can just continue the lists like: form.title9.value = ""; form.title10.value = ""; form.title11.value = ""; - and so on. The problem is that, in the "sentence patterns", I cannot use numbers with two digits to refer to the word lists. Then it thinks I mean 1+0 and 1+1 instead of 10 and 11. How can I allow this? I have heard about using regular expressions to "capture the number by its word boundary" - is this a good solution? If yes, can someone please explain to me how to do it? (I have tried special characters like @,#,$ and more as well as Russian and Greek letters. This makes the script unable to generate poems.) Thank you.

Join Date Jun 2002 Location London, England Posts 18,371 Thanks 204 Thanked 2,573 Times in 2,551 Posts Convert the string values which are concatenated by + (e.g. "2" + "5" = 25) into numbers (e.g. 2+5 = 7) by using the Number() method, or another way is to multiply the value by 1. But you are using string values if (chr == '1') { quite unnecessarily. Remove the quote marks to make them into numbers. "1" is a string value. 1 is a number Obviously chr = pattern.charAt(ichr); only captures a single numeric chararcter. You can extract two-digit numbers from a string just by removing all non-digits var x = str.replace(/[^0-9]/g,""); // strip all characters but digits That of course assumes that there is only one number in the string.

I want to see what the function would look like to be able to convert into different currencies by using arrays. I know that this would be a useless way to do it as they are updated every day, but it's for personal education purposes. (Note: The website contained a textbox in which to enter the amount in pounds, a drop-down box allowing the user to select currency, a button to click to convert, and another text box showing amount of money after converting.) Any help is greatly appreciated. helow to all im new here? iwant to ask on how to display the sum of the 20 numbers i allready get the everage but i want to display the sum together of the everage this my code.. <html> <body> <script type = "text/javascript"> var numtotal = parseInt(prompt("How many numbers do you want to sum up?","")); var total = 0; for (var i=0; i<numtotal; i++) { var ans = parseFloat(prompt ("Enter a number", "")); if ((isNaN(ans)) || (ans == "")) { alert ("You must enter a number!!
