Functions Called Correctly In A Mortgage Calculator
Oct 13, 2009
I've been trying to write a Javascript Mortgage Calculator for the past day and I believe I've got the structure right, although for some reason my functions must not be operating correctly or are not being called correctly. I'm almost afraid to say that it could be an error in the functions usage within the while loop. This Mortgage Calculator uses the principle of "bisection" to guess at the monthly payment necessary to fulfill the standards of the mortgage in question. This means that the loop is used to consistently halve the value of a guess until the correct monthly payment is guessed. Here is the code:
<script type=text/javascript>
function calcMortgage (amountText, yearsText, interestText) {
// constant definitions
// variable declaration
var amount = Number(amountText);
var years = Number(yearsText);
[Code]...
Where could I find a mortgage calculator script I could place on my website? I found a really cool one at www.dave.imarc.net/php free to use but I have a hard time understanding how to install it. I really don't even know what php is.
Could someone maybe guide me out of this programming lingo darkness?
I am trying to create a monthly mortgage calculator, I have been able to make it show prompts for Amount of loan; Interest rate; and Term of loan (in months), but it will not display the results. Below is the code I have utilized to get this far.
<script type="text/javascript"> var num1=prompt('Enter your first number',""); var num2=prompt('Enter your second number',""); var problem=prompt('Enter the operator you wish to use..x,X,+,-,/ are valid..',""); if (problem=="+") { [Code]...
It will open when the page comes up, but how do I put it so that it opens when the user clicks a button?
I am new to Java and my teacher goes way too fast in class and am a day behind on this calculator. Our assignment is to make a Calculator using AppendDigit and Else if functions in the java code. Some of my other code in html may be messed up as well. I am just lost so here is the HTML:
And Here is the pathetic Javascript which I have barely started: Code: // cal Applet- John Falco- 20 October 2010 function clear TB() { document.form.kpd.display.value="0"; } function AppendDigit (x) { if (x==".") { if ((!HasDecimal)) } else { document.forms.kpd.display.value = document.forms.kdp.display.value + X; };
The context: I am trying to fire a Google Analytics Tracking Code, and a Website Optimiser Conversion Script on an Onclick, one after another, before following an external link. It's on an image button. It must work for JS disabled. The Problem: The first one was that the newest browsers were executing the external link before the tags were firing. I added return false; to stop this which it did. This however ignited an old problem I had - being the two scripts just would not fire one after another. The Code:
Ok, so basically what I've got is a button which when clicked, "opens" a section of the page. I also need the button to "jump" to this section of the page, because it's below the current content and won't be visible. What I've got so far is ...
Javascript <script language="javascript"> function toggle() { var ele = document.getElementById("toggleText"); var text = document.getElementById("displayText"); if(ele.style.display == "block") { [Code]....
If I put two separate buttons, both functions will work. Basically I need them to be on the same function, not sure how to do that?
I am building a sliding menu with .hover() and I have a series of three functions within handlerIn() and three within handlerOut(). If you quickly run your mouse over and then off of the hover area, without letting the animate() function complete, the handlerOut() functions don't fire correctly.
Here's the page: [URL]
And here's the code for one of the three (all three are the same): //image sliders $('#build-nav').hover(function() { $('#build-trans').animate({top:'180px'},{queue:false, duration:300, complete:
I can't seem to get the syntax correct to get this to work. I'm sure it is something simple.I want to call multiple functions inside my document.ready function.The first function gets called but not the second.
$(document).ready( function GetSuspectCollection() { $.ajax({[code].....
I'm trying to create a mortgage payment calculator in Javascript and am having problems. My algorithm seems correct but it's not giving the right results. Im using this code:
function do_calc_payment(){var term = document.calc_payment.term.value;var rate = document.calc_payment.rate.value;var amount = document.calc_payment.amount.value;var j = rate / (12*100);var m = term * 12;var payment = amount * ( j / (1 - (1 + j) ^ -m))var result = "$"+Math.round((payment)*1000)/1000;if(isNaN(payment)){document.calc_payment.rate.value="";document.calc_payment.amount.value="";result="Not a Number";}if(payment.length>=15){result="Max Characters";}document.getElementById('new_payment').innerHTML = result;}
Does anybody know of an algorithm to calculate mortgage payments? e.g.
Amount: 100,000 Interest Rate: 4.5% Term: 25 Years
Monthly Payments: x
I've looked at other js scripts to do this but it seems alot more involved then I thought, and because they use non descriptive variable names I can't work any of them out..
I have a mortgage calc that is adding an extra decimal place to my interest rate. To see this in action go to: [URL] Change the interest rate to 7.5 Click Calculate Payment Click Create Amortization Chart On the following screen you'll see a recap of your data and the interest rate will now say 7.55. Same thing happens if you enter 6.2. Next screen shows 6.22/. I've attached the html and js files in a zip.
I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper() { function frequencyWrapperOne() {
I'm trying to make a calculator app; with a few differences. 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).
I have the last assignment that she wants us to do and I had to pull up another assignment that she wanted us to build upon( which is one of those coding without anything advance)
<html> <head> <title>
[code]....
now she wants us to do max <beta and then name the variables with if a<b and I don't know if I put that in the concatenation or what to name my variables!
I am trying to create a price calculator that automatically calculates the price of custom made picture frame. I got an equation that finds the square area of the frame by multiplying the perimeter (2*length*width) by the thickness (which the user can choose from 1.5", 2" or 3"). Then it multiplies it by a decimal number (0.27 if the frame is 1.5" thick, 0.23 if its 2" thick, and 0.18 if its 3" thick). Then it adds a $5 custom made fee to the final answer. But when I save it to an html file and load it in Internet Explorer, it doesn't calculate. Code:
I'm having some problems with a calculator that I'm working on and am stumped on a particular situation regarding adding additional script and how it should be written. I've searched the forum and the web and just cant locate a viable solution. Code:
#display { text-align:right; } </style> <script type="text/javascript"> var find=document.getElementById; var temp=0; var total=0; var which=0; var m=0;
function Mplus() { m=parseFloat(find('display').value) + m; find('memory1').value="M+*"; }
function Mclear() { m=0; find('memory1').value="M+"; }
I'm attempting to create a shopping cart shipping calculator using the total $ provided by the cart itself (%total%). Basically the script needs to take the %total%, compare it to a bunch of arrays in the javascript, and provide the shipping charge as a percentage of the total. For example:
I have a simple calculator written using javascript and html. I would like to make it such that when a link to the calculator is clicked, a pop up window with this calculator appears rather than referring a user to anew page.
