JavaScript - Calculation Coding Assistance Interest
I've been working on this for a few days now and I'm not sure if it could be done or not. I'm trying to do the following complex formula in Adobe Acrobat. I want to be able to calculate tInterest (Total Interest Due) = fDays (# of days) * .0002739726 (interest rate) * PrincipalAmt (principal) but ONLY IF fDays > 90 or if CheckBox1 is checked then fDays > 180, otherwise tInterest = 0.
See, I'm trying to create a form where the interest is only to be calculated if 90 days has elapsed OR 180 days has elapsed if checked off.Either way, interest is to be calculated from StartDate. Is this possible? Similar TutorialsThis is compound. Code: //compound interest
function checkNumber2(input, min, max, msg)
{
msg = msg + " field has invalid data: " + input.value;
var str = input.value;
for (var i = 0; i < str.length; i++)
{
var ch = str.substring(i, i + 1)
if ((ch < "0" || "9" < ch) && ch != '.')
{
alert(msg);
return false;
}
}
var num = parseFloat(str)
if (num < min || max < num)
{
alert(msg + " not in range [" + min + ".." + max + "]");
return false;
}
input.value = str;
return true;
}
function computeField2(input)
{
if (input.value != null && input.value.length != 0)
input.value = "" + eval(input.value);
computeForm(input.form);
}
function computeForm2(form)
{
if ((form.payments.value == null || form.payments.value.length == 0) ||
(form.interest.value == null || form.interest.value.length == 0) ||
(form.principal.value == null || form.principal.value.length == 0))
{
return;
}
if (!checkNumber(form.payments, 1, 480, "# of payments") ||
!checkNumber(form.interest, .001, 99, "Interest") ||
!checkNumber(form.principal, 0, 10000000, "Principal"))
{
form.payment.value = "Invalid";
return;
}
var i = form.interest.value;
if (i > 1.0)
{
i = i / 100.0;
form.interest.value = i;
}
i /=12;
var pow=1;
for (var j=0; j < form.payments.value; j++)
pow=pow * (1 + i);
money="" + .01* Math.round(100*(form.principal.value * pow * i) / (pow - 1));
dec=money.indexOf(".");
dollars = money.substring(0,dec);
cents=money.substring(dec+1,dec+3);
cents=(cents.length < 2) ? cents + "0" : cents;
money=dollars + "." + cents;
form.payment.value = money;
}
function clearForm2(form)
{
form.payments.value = "";
form.interest.value = "";
form.principal.value = "";
}
//STOP compound interest
I'm not a mathmatician (or english major). what do I need to change to make this for fixed interest? Thanks in advance and I didn't know she was your sister in advance. JS beginner here; Ok, I'm trying to manipulate the functions of Codaslider for a layout. What I need is the ability to use an image for slide dynamic slide navigation. I've solved the issue for dynamic hashing, however I'm stuck at modifying the HTML. I've tried a few things but I figure this is the easiest way... This is what I've got so far; function navigate () { var url = document.getElementById('back'); url.href = page_back(); return url; } function page_back(inward) { new Object(inward.location.hash); var rehash = inward.location.hash.match(/[^#]/); if (rehash == 1) { rehash = 5; } else if(rehash == 2) { rehash = 1; } else if(rehash == 3) { rehash = 2; } else if(rehash == 4) { rehash = 3; } else if(rehash == 5) { rehash = 4; } else if(rehash == null) { rehash = 5; } else{rehash = "Invalid URL or REFERRER"} inward.location.hash = rehash; return inward.location.href; }; Implemented here; <a href="#5" id="back" class="cross-link"> <input type="image" class="left_arrow" src= "images/leftarrow.png" onclick="navigate()" /></a> What I expect this to do is change the href value to "#1" so that Codaslider will do it's thing while I provide a stationary dynamic image for slide browsing. Anyone have any idea what i'm doing wrong? page_back works fine but navigate seems to be useless. http://jsfiddle.net/Wsekx/ Populate the following array with string data instead of numeric data, and then test it with these states as data: "Georgia", "Colorado". "Iowa", "Florida", "Kentucky", and "Arizona." How exactly do I do this? So confused after reading this I've been wanting to create a sort of user controlled cms... Something that a user controls no matter if there logged in or not, Something that works on flatfile no PHP no server side scripting. Just browser scripting. I was wondering if this was even possible to do, or if it's been done before. Thanks in advance.
I am needing to use javascript to show a prompt, and when the user enters a number from 1-12 (1 for each month of the year) it adds it to a new array. Then when the user types "stop" it prints the corresponding months. I'm new to javascript so I am not quite sure how to go about doing it. This is what I have currently, but I don't think it is right. Code: <script type="text/javascript">
var month=['', 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
var selmonth= new Array();
var month2=prompt('Which Month', '');
if (month2==1){
selmonth[0] = month[1];
var month2=prompt('Which Month', '');
}
if (month2==2){
selmonth[1] = month[2];
var month2=prompt('Which Month', '');
}
if (month2==3){
selmonth[2] = month[3];
var month2=prompt('Which Month', '');
}
if (month2==4){
selmonth[3] = month[4];
var month2=prompt('Which Month', '');
}
if (month2==5){
selmonth[4] = month[5];
var month2=prompt('Which Month', '');
}
if (month2==6){
selmonth[5] = month[6];
var month2=prompt('Which Month', '');
}
if (month2==7){
selmonth[6] = month[7];
var month2=prompt('Which Month', '');
}
if (month2==8){
selmonth[7] = month[8];
var month2=prompt('Which Month', '');
}
if (month2==9){
selmonth[8] = month[9];
var month2=prompt('Which Month', '');
}
if (month2==10){
selmonth[9] = month[10];
var month2=prompt('Which Month', '');
}
if (month2==11){
selmonth[10] = month[11];
var month2=prompt('Which Month', '');
}
if (month2==12){
selmonth[11] = month[12];
var month2=prompt('Which Month', '');
}
if (month2=='stop'){
document.write(selmonth.join(" <br> "));
}
else{
alert('Please enter a valid value');
}

It'd be great if someone is able to help me. Thanks. i have a selection menu here. what i would like to do is that when i select "not copy" it will not show and not copy the contents of "todo" textfield. but when i select any of the "copy text" it will show and copy the contents of the "todo" text. help plsssssssssssssssssss <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <body> <form id="form" name="form" method="post" action=""> <p>Phone Number: <input type="text" name="Name" /> </p> <p>Location: <select name="selector" > <option>copy text</option> <option>not copy text</option> <option>copy text</option> <option>copy text</option> </select> </p> <p>To Do Today: <input type="text" name="todo" /> </p> <p> <input type="button" value="Copy" /> </p> </form> </body> </html> So I have the jcarousel with pagination working fine. So Im happy with all of the behavior that is going on right now, it is great. My issue is I would liek to have the pagination numbers still change the class on the slide changes, But my one thing is, I want to make the pagination numbers NOT links. So they keep the same hover states and the color changes on slide change, but only the slide carousel arrows can change the slides, and the pagination is only for notification purposes. not links or able to change slides. Can this be done? my code is here http://www.cesariomendoza.com/jcarousel/
I've started studying JavaScript recently. The following simple scenario from the Russian textbook cannot be implemented on my PC. Code: <HTML>

I just typed the script char by char. I use Firefox browser, v.3.5.7. The error console does not display any mistakes. Please, explain me what is wrong in the code. Hi everyone, I am new to Javascript and took a class or 2 in college, but need some help. I need to make a calculation for a webpage that will do the following: Client will insert AWG (wire ) Size, then it will derive the correct Circular Mils that the AWG is equal to from an Access Database ( I assume this is the way to set that up or if I can in Javascript itself, thats fine as well ), then Multiply it by the Number of Strands that the Client will also insert. I had this all set up in Visual Basic and working great, and my boss said he does not want it in a pop up box but prefers it on the website itself hence me reverting to Javascript for this. To visualize it Image 2 boxes with AWG and STRANDS that the client will put in, then another box with TOTAL CMA where the answer will pop up after it has multipled by the AWG individual CMA and number of Strands. I have the general idea to set it up, just do not know how to get the Database in there and Code it properly or whatever. I would appreciate any assistance I can get :-) Thanks everyone. The problem that I am facing is my total amount comes out to $102.46 through my calculations on the page. But when it is moved over to PayPal, the value becomes $102.44. I have many more amount that are also either up .2 cents or down .2 cents. I managed to track this down as a rounding issue. Anytime I do the math, it rounds the amount off and gives the total. But since quantity is involved which is done through PayPal, I had to divide my total by the quantity to bring it back to its original amount thus allowing PayPal to multiply the amount by the quantity. I've pulled my hair out on this one. Ay help would be appreciated. Thank you Code: <html>

Ok I am looking for a simple bmi calculator that calculates body mass index then in a seperate table calculates what a target weight should be based on the goal bmi. no need for making it look fancy, just functionality for now. thanks!
I need help with a javascript calculation. I am a noobie developer as you will probably see by my script but here are my goals: I already have a working bmi calculator for my website where visitor will enter height and current weight to calculate their current bmi. then I want to have a reverse bmi calculator to grab the same height and weight from said bmi calculator to give a calculation with a fillable goal bmi (example: 18-24 "healthy bmi") to read out a goal weight for them to achieve. I have already figured out the first part of the bmi calculation now i just need the second calculation to grab the height and weight from original bmi calculator without needing to be filled in again and compute result in a second table. I will post code that I have come up with so far for the whole page. Thank you in advance for your help!

I have a text field with a numberpad below it, I got the numbers to show up in the text field, but am unsure as to how when I hit the enter button - it would store them in a variable?...I am also wondering as to how it would store current value and then allow me to input another value(maybe on the next page) and either subtract or add to it(the first value that is stored). I am also wondering how to get a decimal point in place(need it for currency). Any help would be greatly appreciated! Here is my code: Code: <html>
<head>
<script type = "text/javascript">
function decPoint(str){
if (str.indexOf('.') == -1) str += ".";
var decNum = str.substring(str.indexOf('.')+1, str.length);
if (decNum.length > 2)
{
alert("Invalid more than 2 digits after decimal")
}
else {
alert("Valid no")
}
}
var ent = document.write(document.getElementById("curamt").value);
</script>
</head>
<body border = "1"; color = "blue";>
<div id = "cur">
<p>amount is: <script>document.getElementById("amount").innerHTML = ent);</script>
</p>

Hi Guys, I would like to add a confirmation to this: PHP Code: echo "<a href=\"delete.php?dir=$dir&file=$file\" onclick='return del(this, \"$id\")'><img src=\"images/delete.gif\" border=\"0\" /></a>"; However I seem to be struggling, severely! Any help would be greatly appreciated, especially if spelt out if alphabetti spaghetti. Kind Regards, Drew Hello, I have a form that calculates a dollar amount based on the percentage entered by the user. Now the client wants the form to also calculate the percentage if the user enters a dollar amount. I am new to this so I am having trouble figuring out how to format the if statement. Here is the code that performs the calculations: Code: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$(".TextBox").hover(function(){
$(this).toggleClass('TextBoxSelected');
},function(){
$(this).toggleClass('TextBoxSelected');
}).change(function(){
calculate();
});
});
function getFldValue(fldValue) {
return isNaN(fldValue) ? 0 : parseFloat(fldValue);
}
function calculate() {
var property_SPrice = getFldValue($('#property_SPrice').val());
var price = getFldValue($('#price').val());
var REO_sale_percentage = getFldValue($('#REO_sale_percentage').val());
var REO_sale_dollars = getFldValue($('#REO_sale_dollars').val());
var REO_sale_bonus_dollars = getFldValue($('#REO_sale_bonus_dollars').val());
var REO_sale_fixed_dollars = getFldValue($('#REO_sale_fixed_dollars').val());
var REO_sale_total_dollars = getFldValue($('#REO_sale_total_dollars').val());
var REO_list_percentage = getFldValue($('#REO_list_percentage').val());
var REO_list_dollars = getFldValue($('#REO_list_dollars').val());
var REO_list_bonus_dollars = getFldValue($('#REO_list_bonus_dollars').val());
var REO_list_fixed_dollars = getFldValue($('#REO_list_fixed_dollars').val());
var REO_list_total_dollars = getFldValue($('#REO_list_total_dollars').val());
var gr_comm_percentage = getFldValue($('#gr_comm_percentage').val());
var gr_comm_dollars = getFldValue($('#gr_comm_dollars').val());
var gr_bonus_dollars = getFldValue($('#gr_bonus_dollars').val());
var gr_fixed_dollars = getFldValue($('#gr_fixed_dollars').val());
var gr_total_dollars = getFldValue($('#gr_total_dollars').val());
$('#price').val(property_SPrice);
$('#gr_comm_percentage').val(REO_list_percentage + REO_sale_percentage);
$('#gr_comm_dollars').val(getFldValue(REO_list_dollars + REO_sale_dollars));
$('#REO_list_dollars').val(getFldValue(REO_list_percentage/100*price));
$('#REO_sale_dollars').val(getFldValue(REO_sale_percentage/100*price));
$('#gr_fixed_dollars').val(getFldValue(REO_list_fixed_dollars + REO_sale_fixed_dollars));
$('#gr_bonus_dollars').val(getFldValue(REO_list_bonus_dollars + REO_sale_bonus_dollars));
$('#gr_total_dollars').val(getFldValue(REO_sale_total_dollars + REO_list_total_dollars));
$('#REO_sale_total_dollars').val(getFldValue(REO_sale_dollars + REO_sale_fixed_dollars + REO_sale_bonus_dollars));
$('#REO_list_total_dollars').val(getFldValue(REO_list_dollars + REO_list_fixed_dollars + REO_list_bonus_dollars));
}
</script>
I now need to add: Code: $('#REO_list_percentage').val(getFldValue(REO_list_dollars/price*100));
$('#REO_sale_percentage').val(getFldValue(REO_sale_dollars/price*100));
So that if the user enters a dollar amount, the form can calculate the percentage along with all of the other calculations above. How would I write that? Thanks. I wish to create an applett, which i am working on, Though I want to know if there is any way to: 1) Take screenshots of entire web page 2) Take screenshots of a certian part of the web page selected by the user with a Rectangle tool 3) Take screenshots of a certian part of the web page selected by the user with a FreeForm tool Im not asking for a full code or anything, But I just wish to know in what way could i go about this? Evening all, I am by no means a JS programmer, but I like to exhaust all avenues when attacking an issue. A signature fired off on a piece of javascript that came across the wire, with an odd "var unescape" inside of it. I am hoping to throw this code out there, to see if anyone has any insight on what this might be. I am assuming this is double encoded, but I am not certain. Here is the snippet of code the signature fired off from: var ibdf=unescape("%u0b0b%u0b0"+"b"); var fdofdopf="xcvb9090"; Thanks in advance for anyone willing to assist with this. Cheers, Anon I am a student trying to complete this assignment. Any assistance you can give me is greatly appreciated. My code is inserted below. This is calculator program that I have gotten stuck on. Here is where I think I am at: The program is now taking the 1st number entered displaying it and storing it in the variable "memory". Operation (+,-,*,/) is added to the memory in function action1() but then when the second number is entered it replaces memory with the second number. How can I get the variable memory to the whole string of 1st number,action, 2nd number? Also once I do get that working correctly: Wouldn't eval(document.calculator.display.value= memory) in my HTML for the "=" give me the calculation. ( if I could figure out how to have memory store the 1st number and action1 and 2nd number all together) Or would eval(document.calculator.display.value) do it for me. //////////////////////////////////////////////////////////////////////////////////// <html> <head> <title> Calculator</title> </head> <script type = "text/javascript" src="calculator2.js"></script> <body> <center>Calculator<br> To use this calculator, CLICK a number, then an ACTION, then another number, then the EQUALS button. <br> Press "C" when ready to start over. <br> The "N" button makes your previous number a negative.<br></center> <form name="calculator"> <table border = "1" align ="center"> <tr> <td ><input type = "text" size = 26 name = "display" id = ""/></td> </tr> <tr ><br /> <!-- first row of calculator --> <td> <input type = "button" value = " 7 " id = "" onclick="newstring('7')"> <input type = "button" value = " 8 " id = "" onclick="newstring('8')"/> <input type = "button" value = " 9 " id = "" onclick="newstring('9')"> <input type = "button" value = " / " id = "" onclick="action1('/')"> </td> </tr> <tr ><br /> <!-- second row of calculator --> <td> <input type = "button" value = " 4 " id = "" onclick="newstring('4')"> <input type = "button" value = " 5 " id = "" onclick="newstring('5')"> <input type = "button" value = " 6 " id = "" onclick="newstring('6')"> <input type = "button" value = " * " id = "" onclick="action1('*')"> </td> </tr> <tr ><br /> <!-- third row of calculator --> <td> <input type = "button" value = " 1 " id = "" onclick="newstring('1')"> <input type = "button" value = " 2 " id = "" onclick="newstring('2')"> <input type = "button" value = " 3 " id = "" onclick="newstring('3')"> <input type = "button" value = " - " id = "" onclick="action1('-')"> </td> </tr> <tr ><br /> <!-- forth row of calculator --> <td> <input type = "button" value = " 0 " id = "" onclick="newstring('0')"> <input type = "button" value = " N " id = "" onclick="newstring('N')"> <input type = "button" value = " = " id = "" onclick="eval(document.calculator.display.value= memory)"> <input type = "button" value = " + " id = "" onclick="action1('+')"> </td> </tr> <tr ><br /> <!-- fifth row of calculator --> <td> <input type = "button" value = "   " id = ""> <input type = "button" value = "   " id = ""> <input type = "button" value = "   " id = ""> <input type = "button" value = " C " id = "" onclick="clearCalc()"> </td> </tr> </table> </body> </form> </html> /////////////////////////////////////////////////////////////////////////////////////// javascript memory = "0"; current = 0; operation =0; function newstring(digit) { current=document.calculator.display.value; if (digit >= 0 && digit <=9) { if(current==0) { current = digit; } else { current = current + digit; } } document.calculator.display.value=current; memory= current; } function action1(newaction) { operation = document.calculator.display.value; if (newaction == '+') { operation = newaction; } else if (newaction == '-') { operation = newaction; } else if (newaction == '*') { operation = newaction; } else if (newaction == '/') { operation = newaction; } memory= memory + operation; document.calculator.display.value=memory ; } function clearCalc() { document.calculator.display.value=null; num1= null; num2 = null; lastaction= null; action = null; } |
