JavaScript - Formatting Numbers In Javascript
I am creating a calculator app and I'm a bit stuck with number formatting.
Example of how I would like a number to be formatted: $2,899,799 I currently have the formatting working except for the commas. I'm using the following code to achieve this. My result is currently showing up like this $2899799 Code: function format (expr, decplaces) {
var str = "" + Math.round (eval(expr) * Math.pow(10,decplaces))
while (str.length <= decplaces) {
str = "0" + str
}
var decpoint = str.length - decplaces
return str.substring(0,decpoint) + str.substring(decpoint,str.length);
}
function dollarize (expr) {
return "$" + format(expr,0)
//RESULT FIELDS
form.AnnualScrapSales.value = dollarize(((A - B) * (C2/100)) * G2)
is there a way to add to this "function format" code to also achieve the commas? Similar TutorialsI am using Javascript validation, for all my HTML control that are not run at server... Now i need to allow the user to enter only numbers in a textbox..If any of them apply characters alert should come.. How can i do that in javascript.... I can't figure out how to properly format the code below. I am looking to add breaks after where it says below. Also to change the color if possible. Any help would be much appreciated. function isPPC() { if (navigator.appVersion.indexOf("PPC") != -1) return true; else return false; } if(isPPC()) { document.write('<b>Send <A CLASS="contact" HREF=\"mailto:\?subject\=ADD A BREAK AFTER THIS ' + document.title + '?body= ADD A BREAK AFTER THIS ' + '\" onMouseOver="window.status=\'Send your friends e-mail about this page\'; return true" TITLE="Send your friends e-mail about this page">this page<\/A> to a friend</b>'); } else { document.write('<b>Send <A CLASS="contact" HREF=\"mailto:\?body\=ADD A BREAK AFTER THIS ' + document.title + ' ADD A BREAK AFTER THIS ' + '\" onMouseOver="window.status=\'Send your friends e-mail about this page\'; return true" TITLE="Send your friends e-mail about this page">this page<\/A> to a friend</b>'); } I need to make a --very-- simple version of this game: http://javascript.internet.com/games/magic-squares.html. You need to click on the buttons until they're in order, then you win. I'm having trouble with the function that trades the places of the two buttons. So, can anyone tell me how my "swap" function should be? It needs to test if the value of the button next to the button clicked on is blank, and then if it is, the two values trade places. This way, I will hopefully end up with 9 different functions, depending on which square I'm clicking on, because the "id" of the button stays the same, it just swaps the values. It shouldn't use any arrays or anything. Thanks, I appreciate the help! Here's what I have so far: Code:
<html>
<head>
<title>15 Puzzle</title>
<script type="text/javascript">
function swap(id){
if(document.getElementById(id+1).value="")
{
document.getElementById(id+1).value=document.getElementById(id).value;
document.getElementById(id).value="";
alert('It works!');
}
}
</script>
</head>
<p><h1 align="center">15 Puzzle</h1><p>
<p align="center"><input type="button" id="scramble" value="Scramble"></p>
<br>
<table border="3" bordercolor="black" width="300" bgcolor=""

I've been trying to get random numbers in JS. It works when I assign fixed values, but when I want those values to come from a form, I get all the problems.. any comments on my script? Thanks. M [CODE] <script type="text/javascript"> function random() { var x=document.getElementById("text1").value;// num ingresado por el usuario var y=document.getElementById("text2").value; //var x=1; //var y=6; num=Math.floor(x + Math.random() * y); var r=document.getElementById("demo") r.innerHTML=num; } </script> [CODE] I'm trying to remove a vertical scroll that appeared after I added padding 100% to footer. It was suggested that I use javacript to cause the footer not to expand so I don't have to add padding 100% to footer which will eliminate scroll bar. How do I accomplish this when you remove 100% padding from footer?I don't want to see the grey backgroun under footer. I just want to see footer and that's it. Here's my code Code: <!DOCTYPE HTML>

I have the table sorted properly and my current script (within the table) adds up all three T columns and brings the total to 72.001 as expected, woot! Where I'm stuck is converting the 72.001 to 1 minute 12.001 seconds (1:12.001) and I need to have it include the thousandths since the game gives that information. Once I get the JS going for the top row I can copy down Any advice on converting this is greatly appreciated and I Bolded the JS I'm referring to: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Oh, and any help on centering the result in the cell (72.001) would be excellent too, thank you. Jerome Hi so because the jquery range slider has no date range ability and because the only date range plugin for jquery UI sliders is very bloated and fails to work on modern ipad / new touch event methods... I'm writing my own today.. Can some one better exmplain to me how to do: "theCurrentDate (05/12/2012) - anOlderDate (05/12/1990) = difference of how many days is?" and "theCurrentDate (05/12/2012) - 200 = but resulting in date formatted version, not some 9394829398 number"? Thanks! This has been driving me nuts, let me start off by saying this is what I'm currently working with... I've included a js file in the header of the site which utilizes a function in a php file. Just the standard Code: <script language="javascript" src="http://yourwebsitehere.com/includes/js.js"></script> In the .js file I'm setting the location to a php file as a variable... Code: var url="/file-here.php"; url=document.location.host+url; Obviously the document.location.host isn't working for me but here's what's going on... At first I just had, Code: var ="http://www.domain.com/file-here.php"; in the js file. So if the user is on www.domain.com/some-directory/another/ the script will work, however if the user is on domain.com/some-directory/another the script won't work, because I've included www. in the variable within the js file. However, if I set it to Code: var ="http://domain.com/file-here.php"; , it will work on domain.com/some-directory/ but not on www.domain.com/some-directory. So basically I need to return the host url somehow, depending on if the user is on the page with www. or without www. so it will always work. With php, I could just use Code: $server['HTTP_HOST']/file-here.php and it will always return www.domain.com or domain.com depending on the URL the user is on, but obviously php won't work in a js file so I'm looking for the correct string/command to get this. Anyone have any idea how to return just the www.domain.com or domain.com portion of the current URL with javascript? So no matter where they are on the site, with or without www. the script can still function by having the correct URL to the PHP file at all times? Hello! I have a really simple JavaScript calculator I'm running, and for the life of me can not figure out how to solve this crazy number problem. It's not doing the math properly, and javascript is not my strongest suit. All my script does is take user input of numbers into a form field, subtract that from another form and multiply the answer of those two forms by whatever the user put in. Example: 210 (minus) 120 (multiplied by) .90 = 81 Here is the actual script: Code: // Calculator
function CalculateSum(Atext, Btext, Ctext, form)
{
var A = parseFloat(Atext);
var B = parseFloat(Btext);
var C = parseFloat(Ctext);
form.Answer.value = A - B * C;
}
/* ClearForm: this function has 1 argument: form.
It clears the input and answer fields on the form.
It needs to know the names of the INPUT elements in order
to do this. */
function ClearForm(form)
{
form.input_A.value = "";
form.input_B.value = "";
form.input_C.value = "";
form.Answer.value = "";
}
// end of JavaScript functions -->
And the html I am using: Code: <form name="Calculator" method="post">
<p>Base Average<input type=text name="input_A"></p>
<p>Current Average:<input type=text name="input_B"></p>
<p>Percentage of:<input type=text name="input_C"></p>
<p>Your ball speed is:
(miles per hour)
<input name="Answer" type=text readonly>
</p>
<p>
<input type="button" value="Calculate Handicap" name="AddButton" onClick="CalculateSum(this.form.input_A.value, this.form.input_B.value, this.form.input_C.value, this.form)">
<input type="button" value="Clear" name="ClearButton" onClick="ClearForm(this.form)">
</p>
</form>

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>

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 Hi, Want to add numbers using JS. Have 4 text boxes for user entry. Want either a label (preferred) or fifth text box to automatically sum those entries. Did following but not working. Any suggestions? <script language="javascript"> var addRange = function() { var NoHrsRangeComp = document.getElementById("NoHrsRangeComp"); var NoHrsRangeCred = document.getElementById("NoHrsRangeCred"); var NoHrsRangeOT = document.getElementById("NoHrsRangeOT"); var NoHrsRangeRC = document.getElementById("NoHrsRangeRC"); var RangeSum = document.getElementById("RangeSum"); var sum = 0; if (isNaN(parseFloat(NoHrsRangeComp.value))){ NoHrsRangeComp.value = ""; } if (isNaN(parseFloat(NoHrsRangeCred.value))){ NoHrsRangeCred.value = ""; } if (isNaN(parseFloat(NoHrsRangeOT.value))){ NoHrsRangeOT.value = ""; } if (isNaN(parseFloat(NoHrsRangeRC.value))){ NoHrsRangeRC.value = ""; } sum = parseFloat(NoHrsRangeComp.value) + parseFloat(NoHrsRangeCred.value) + parseFloat(NoHrsRangeOT.value) + parseFloat(NoHrsRangeRC.value); RangeSum.innerHTML = sum; } </script> Input as follows: <input style="width: 50px" type="text" name="NoHrsRangeComp" id="NoHrsRangeComp" onblur="addRange();"/> <input style="width: 50px" type="text" name="NoHrsRangeCred" id="NoHrsRangeCred" onblur="addRange();"/> <input style="width: 50px" type="text" name="NoHrsRangeOT" id="NoHrsRangeOT" onblur="addRange();"/> <input style="width: 50px" type="text" name="NoHrsRangeRC" id="NoHrsRangeRC" onblur="addRange();"/> <input style="width: 50px" type="text" name="RangeSum" id="RangeSum" onblur="addRange();"/> For above entry prefer - label makes it look more like usual addition and does not confuse users to want to make entry. <label id="RangeSum" onblur="addRange();" style="border-bottom:medium"></label> John This textbook is complete garbage, there is nothing in this thing about this topic at all. Here is the question I am trying to do: "Suppose you have a sequence of numbers Where every number is the previous number plus 3 1, 4, 7, 10, 13, 16, 19, 22 Write a program to output the first 10 number s of the sequence. You must calculate the numbers, you cannot just hard-code them into an array." Its a question on a test study guide. Heres what I got so far: Code: <html> <head> <script type="text/javascript"> VarX = 1 i = 3 VarY = VarX + i count++ do varY while count < 10 </script> </head> <body> </body> </html> Hi, I have this bit of java code that puts a random/unique number in a field on my web page: <html> <head> </head> <body> <form> <input type="text" name="MyField" /> </form> <script langueage="javascript" type="text/javascript"> var d = new Date(); var tm = d.getTime(); document.getElementsByName('MyField')[0].value=tm; </script> </body> </html> My problem is that I want to limit the number to just 6 digits. Is this possible? Any help would be much appreciated Thank you Dave |
