JavaScript - Help With An Update To Variable
function amort(balance, interestRate, terms)
{ var monthlyRate = interestRate/12; var payment = balance * (monthlyRate/(1-Math.pow( 1+monthlyRate, -terms))); var result = "Loan amount: $" + balance.toFixed(2) + "<br />" + "Interest rate: " + (interestRate*100).toFixed(2) + "%<br />" + "Number of months: " + terms + "<br />" + "Monthly payment: $" + payment.toFixed(2) + "<br />" + "Total paid: $" + (payment * terms).toFixed(2) + "<br /><br />"; result += "<table border='1'><tr><th>Month</th><th>Balance</th>" + "<th>Interest</th><th>Principal</th>"; for (var a = 1; a <= terms; ++a){ result += "<tr><td>"+a +"</td>"; //for (var b = balance; b > 0; (balance-payment)){ var updatedBalance = balance;//updated monthly payment var monthRate = monthlyRate*balance;//amount of int per month var monthlyPrincipal = payment-monthRate;//updated monthly principal result += "<td>" + (updatedBalance.toFixed(2))+ "</td>"+ "<td>" + monthRate.toFixed(2) + "</td>" + "<td>" + (monthlyPrincipal.toFixed(2)) + "</td>"; if (balance > 0) { var updateBalance = balance-monthlyPayment; } //} result += "</tr>"; } result += "</table>"; return result; } This is my JS file and I am trying to create a loan table. The table is working and it puts the data in, but the updatedBalance is not decreasing when it goes thru the loop. I thought that if I put an IF statement in to update the amount after each time thru that would fix it. But instead it broke it. Any thoughts.

Hi, I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it. I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page. Thanks for all the help P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side... Hi! I have a javascript in the head of the document which has a variable named "ref2" ... ref2 is already working as I can see its value working in another function. I need to send this variable as the value of a hidden field in the form which is in the body of the document. This is my JavaScript Code: Code: function WriteContactFormStatement1 () {
var ContactFormValue = ref2;
document.write('<input type="hidden" name="UReferrersName" value="' + ContactFormValue + '" />');
}
var WriteContactFormStatement = WriteContactFormStatement1 ();
And at the end of my form, before the submit button, I have the following code: Code: <!-- START -- Javascript to print the statement for UReferrersName --> <script language="JavaScript" type="text/JavaScript"> //WriteContactFormStatement(); document.write (WriteContactFormStatement); </script> <!-- End -- Javascript to print the statement for UReferrersName --> When I execute the form, it doesn't work the way it should, plus, gives me a word "undefined" next to the "Submit" button ..... Please help !... - Xeirus. Hello I have a php page in which I declared a js variable... right at the top of the page... <script type="text/javascript"> var tester = 0; </script> Later in the page I test this variable... <script type="text/javascript"> if (tester==1){ do some stuff!! } </script> But I keep getting an error variable _tester undefined Am I missing something obvious... I am new to js... but this seems really straightforward I don't know how I should do ? Quote: <html> <head> <script type="text/javascript"> function add(a,b){ y=a+b return y } var aaa = add(one,two) //one needs to get somehow get the value of yil, in this case 10 var one = function reas(){i=10;if(i<10){yil = 15}; else{yil = 10; yil = one;}; var two = 20; document.write(y) </script> </head> </html> also why doesn't this work? Quote: <html> <head> <script type="text/javascript"> function adder(a,b){ var k=a+b; return k } var hes=adder(5,kol); kol=40; alert(hes); </script> </head> </html> you cannot have variables in callback functions? If I manually write out "2/22/2012 4:00 PM" in TargetDate, I get the correct result for what I want to do (a countdown). But I want the countdown to always be the current day at 4pm. So I tried the code below thats commented, but it is not working. New to javascript, still reading the books, just hoping for some guidance on this. Code: Next Update: <script language="JavaScript"> var currentTime = new Date() var month = currentTime.getMonth() + 1 var day = currentTime.getDate() var year = currentTime.getFullYear() TargetDate = "2/22/2012 4:00 PM"; //TargetDate = "document.write(month + "/" + day + "/" + year) + 4:00PM"; BackColor = "white"; ForeColor = "red"; CountActive = true; CountStepper = -1; LeadingZero = true; DisplayFormat = "%%H%% H, %%M%% M, %%S%% S"; FinishMessage = "Forecasts posted"; </script> <script language="JavaScript" src="countdown.js"></script> This might be a stupid question, but is there any memory usage difference between var variable1, variable2; and var variable1; var variable2;? I'm learning how to use faster code hence the question.
Hello everybody I have a problem with Java Script damned I want to add the values of several variables in one variable and then use this variable, which contains the values of variables You can see the following example HTML Code PHP Code: <input type="text" name="txt1" /> <br/>age <input type="text" name="txt2" /> <br/><br/> <input type="button" name="submits" value="send"/> Javascript Code PHP Code: field = document.getElementsByName('txt1')[0]; field2 = document.getElementsByName('txt2')[0]; submit = document.getElementsByName('submits')[0]; data = 'data=' + field.value + '&data2=' + field2.value + '&submits=' + submit.value; document.getElementsByName('submits')[0].onclick = function(){ alert(data); } After executing this code I find that the variables are not displayed values As in the following picture I want to know what the cause of this problem ? Hello I have a piece of javascrip that refreshes the page: ---------- Code: <script type="text/javascript">
<!-- Begin
function reFresh() {
location.reload(true)
}
/* Set the number below to the amount of delay, in milliseconds,
you want between page reloads: 1 minute = 60000 milliseconds.
2 minutes = 120000 milliseconds 5 minutes = 300000 milliseconds*/
window.setInterval("reFresh()",20000);
// End -->
</script>
-------- I am new to javascript and wanted to use an html options menu in order to be able to choose the refresh interval: Code: <SELECT NAME="refreshtime"> <OPTION VALUE="60000">1 min</option> <OPTION VALUE="120000">2 min</option> <OPTION VALUE="180000">3 min</option> <OPTION VALUE="240000">4 min</option> </SELECT> I know that I have to pass a variable to the function. I have tried several variations but none have worked. I have mostly received a "done with errors" warning. Any help would be appreciated. Thanks Zam Can anyone tell me of how to take or assign a javascript variable into php.
Hi, I want to write some javascript code that uses arrays, I have a list of arrays named array1, array2, array3 etc. I want to perform a function on each of these arrays. I wanted to have a variable for the number after array so this is what I have: <code> var array1 = new Array ("1","2","3","4","5"); var array2 = new Array ("5","6","7","8","9"); for (var i=1; i<=2;i++){ document.writeln(("array"+i)[1]); } </code> the problem is it gives me the letters in the string array instead of the array values. How do I get javascript to treat ("array"+i) as array1? Hi All, I have a web camera stream which exports JPG which are over written (ie; 5 jpg's) looping. I'm streaming this feed however, setInterval - refreshImage, 1000 is not lining up with the streaming feed. Is there a way to update the latest jpg image without using setInterval times. I find that depending on the server the timing can be off, and it overlaps or goes too fast. This is my code. Code: <html>

Hello, I'm somewhat new to JavaScript and for my website, I decided to make a clock for the website in this format: Saturday, October 17, 2009 5:56:14 p.m. The only issue is that it won't update every second. Below is the coding: External JavaScript: Code: function dateClock()
{
// Coding
}
setTimeout("dateClock()", 1000);
HTML: Code: ...
<script src="date.js" type="text/javascript">

What can I do to make it update? Thanks. Hi everyone - would anyone be able to assist with a code for updating information on a daily basis? For example, I wish to update a section of our site every day that has the following timing information: Everything is tabulated in excel and/or csv, and it also has on line pages in monthly format, but on the main index page, I just need to have a small area that provides it on a daily basis without having to go to an individual monthly page. Dawn Sunrise Mid Day Sunset Hope this make sense! In the same regard, a code that has QUOTES can also be included with daily (automatic) changes. Any help would be greatly appreciated! Thank you! I know im not supposed to use this for someone to write my codes for me but i need help with something the page AtreusComputers is what im working on at the bottom of the page is a price box which i might move to the side or the top later but right now just trying to get it to work here is my html page code Code: <html>

*PARTS IN RED ARE WHAT IM WORKING ON I've got a simple script that generates a button that sends to the printer when clicked. But a totally new thing to me is finding a way to update a "printed_unprinted" field in the database for that item. Anyone have experience with this? Right now, I just have: Code: <style type="text/css" media="print">
@page { size:8.5in 11in; margin: 1cm }
.printbutton {
visibility: hidden;
display: none;
}
</style>
<script>
document.write("<input type='button' " +
"onClick='window.print()' " +
"class='printbutton' " +
"value='Print This Page'/>");
</script>
I assume I could reference a php file? Just something quick like: PHP Code: <?php include("include/conn.php"); $id = mysql_escape_string($_POST['printed']); $query_update = "UPDATE tbl_registration SET reg_hardcopied = '1' WHERE reg_id = '$id'"; $dberror = ""; $ret = mysql_query($query_update); if(!$ret){} else{ //back to referrer } ?> Hi, I have a BMI calculator that records my height / weight and BMI and I can change it then it updates, I'd like to be able to add one for each day and show all in a loop here is my current JavaScript: Code: /***
