Good evening! I'm teaching myself to code. Right now, I'm making a JavaScript loan calculator, but I hit a snag. If I put 0% interest, it displays nothing in my output textboxes. Everything else is working perfectly though. Any help would be appreciated. Thanks!

When you put 0 you are getting
var x = Math.pow(1 + interest, payments); // 1
var monthval = principal * x * interest / (x - 1); //NaN because 1-1 in fraction is 0 so it returns 0/0 and it's NaN
you can change you code to be like this:
if (interest===0){
var monthval = (principal)/(months_in_year);
} else {
var monthval = (principal*x*interest)/(x-1);
}
Working Version: http://codepen.io/mhadaily/pen/ZpypdA
feel free to change it to be like what you want.
It's because of this section of code.
else if (interest == 0) {
document.loaninfo.payment.value = "";
document.loaninfo.total.value = "";
document.loaninfo.totalinterest.value = "";
}
When the interest is 0, you are setting the values of all your output boxes to an empty string.
You should replace the RHS of the assignment.

I am in the process of writing a webpage. I have everything done that is needed, however, when you enter any quantity over 30 it will make the id = "shipping" color red. It does this but it does it for anything less than 30 as well. Also I am having trouble with my submit button sending off to a server/url. Any help is appreciated! I will attach my code!

Problem with your values qty1,qty2,qty3. these values are reading as string. so instead of addding these values , its concatinating the strings. replace
var qty1 = document.getElementById("Quantity1").value;
var qty2 = document.getElementById("Quantity2").value;
var qty3 = document.getElementById("Quantity3").value;
with
var qty1 = parseInt(document.getElementById("Quantity1").value);
var qty2 = parseInt(document.getElementById("Quantity2").value);
var qty3 = parseInt(document.getElementById("Quantity3").value);
It will Solve your problem with 'Red'.
For the submit button, function total() is not returning anything. so change something like
function total() {
var p1 = document.getElementById("Price1").value; //Value is referenced to the input tag
var p2 = document.getElementById("Price2").value;
var p3 = document.getElementById("Price3").value;
var qty1 = parseInt(document.getElementById("Quantity1").value);
var qty2 = parseInt(document.getElementById("Quantity2").value);
var qty3 = parseInt(document.getElementById("Quantity3").value);
var over = qty1 + qty2 + qty3;
if (realNumber()) {
var totals = (p1 * qty1) + (p2 * qty2) + (p3 * qty3);
var yes = (totals).toFixed(2);
document.getElementById("ProductTotal").innerHTML = "$" + yes;
if (over > 30) {
document.getElementById("shipping").style.color = "red";
return true;
} else if(over>0) {
document.getElementById("shipping").style.color = "black";
return true;
}else{
document.getElementById("shipping").style.color = "black";
return false;
}
}
}
and checkout() as
function checkOut() {
if (total()) {
if (((document.getElementById("shipping").style.color == "red") &&
(document.getElementById("extra").checked))||
(document.getElementById("shipping").style.color != "red")) {
return true;
}
}
return false;
}
Replace
var over = qty1 + qty2 + qty3;
With
var over = parseInt(qty1) + parseInt(qty2) + parseInt(qty3);
There were some minor HTML errors but the real issue is that numeric strings were being concatenated. So, to get the quantity values you need to use parseInt() to extract the integer value so that math is performed instead of string concatenation. Also, it's a little odd that the user has to click the Calculate Button in order to see a total. The button does work correctly, but is this what you really want?
One more thing, as tempting as it may be to directly alter the color of elements with JavaScript, in terms of keeping the code more robust, it is preferable to simply change the class name as the code does in this example since I created two classes in the CSS for this purpose.
The form now submits as long as the checkbox is unchecked and the units do not exceed 30. I changed the method to "post" and adjusted the true/false return statements in checkOut(). Note when data is submitted using the POST method, then no form data appears appended to the URL; for more info see here. I also altered the totals() function so that now it returns a value, namely the total price.
var d = document;
d.g = d.getElementById;
var qty = [0, 0, 0, 0];
var shipping = d.g("shipping");
function realNumber() {
var qtyInvalid = [0, 0, 0, 0];
for (let i = 1, max = qtyInvalid.length; i < max; i++) {
qtyInvalid[i] = (isNaN(qty[i]) || qty[i] < 0);
}
if (qtyInvalid[1] || qtyInvalid[2] || qtyInvalid[3]) {
console.log("The quantity given is not a real number or is a negative number!");
return false;
}
return true;
}
function total() {
var over = 0;
var price = [0, 0, 0, 0];
for (j = 1, max = price.length; j < max; j++) {
price[j] = d.g("Price" + j + "").value;
qty[j] = d.g("Quantity" + j + "").value;
}
var totals = 0;
var yes = 0;
const radix = 10;
for (q = 1, max = qty.length; q < max; q++) {
over += parseInt(qty[q], radix)
}
//console.log(over);
if (!realNumber()) {
return false;
}
for (let k = 1, max2 = price.length; k < max2; k++) {
totals += (price[k] * qty[k]);
}
yes = (totals).toFixed(2);
d.g("ProductTotal").innerHTML = "$" + yes;
shipping.className = (over > 30) ? "red" : "black";
return totals;
} // end total
function checkOut() {
var retval = false;
var shippingIsRed = (shipping.className == "red");
var extraChecked = d.g("extra").checked;
if ( total() ) {
retval = (!shippingIsRed && !extraChecked)? true : false;
}
return retval;

I also removed some unnecessary repetitive code that fetches the quantity values, taking advantage of JavaScript closures and for-loops.

I'm trying to make a webpage that allows the user to enter from 4 to 6 grades for any course. Next to the letter grade, I'm wanting to put a text-field that accepts the credit hours for the courses. Also when the Calculate GPA button is clicked I want it to verify that a letter grade has been entered and then accumulate the grade points as well as the credit hours and display the GPA. I'm having trouble getting the GPA to calculate though. As well as having an alert display when a user enters anything other than a letter grade? Can someone look over my code and tell me what I should fix or add? Thanks if you read this and attempt to help!

Few remarks:
I don't think you need to worry about old browsers as no one should be using them nowadays. Therefore, <!--Hide from old browsers --> not needed.
What's the point of calculating the GPA when the page loads i.e. onload? There are no grades when the page loads up, so you'll always get an error. It is probably better to only calculate when the user clicks the button.
Do not repeat yourself.
Do not write for yourself to only read but for others, so comment your code.
Check this answer on the difference between dot notation and square brack notation when it comes to accessing an object property.
eval() is evil and not needed in your code.
Here's how I would do it (hopefully it answers all your questions):
// an object is a better data structure for storing grading scale
var gradingScale = {
'A+': 4,
'A': 4,
'A-': 3.7,
'B+': 3.3,
'B': 3,
'B-': 2.7,
'C+': 2.3,
'C-': 1.7,
'D+': 1.3,
'D': 1,
'D-': 0.7,
'F': 0.0
};
// note in JS, you can reference an element by their ID
// attaching onclick event handler to your button with ID "gpacalc"
gpacalc.onclick = function() {
var totalGradePoints = 0;
var totalCredits = 0;
// easier to just start at 1
for (var i = 1; i <= 6; i++) {
// you can access an object's property using [] notation; useful in this situation
// good idea to normalize your values e.g. trim, uppercase, etc
var grade = document.calcGpaForm['grade' + i].value.trim().toUpperCase();
var credit = document.calcGpaForm['credit' + i].value.trim();
// skip if no grade is entered
if (grade == "") {
break;
}
// check if grade is invalid i.e. not in the grading scale
if (!gradingScale.hasOwnProperty(grade)) {
alert("'" + grade + "' is not a valid letter grade. Course " + i + ".");
return;
// check if credit is empty
} else if (credit == "") {
alert("You left the number of credits blank for Course " + i + ".");
return;
// check if credit is not a number
} else if (isNaN(credit)) {
alert("Enter a valid number of credits for Course " + i + ".");
return;
}
// at this point, the grade and credit should both be valid...
credit = parseInt(credit, 10);
// so let's add them to the tally
totalGradePoints += gradingScale[grade] * credit;
totalCredits += credit;
}
// check if total credits is greater than zero
if (totalCredits == 0) {
alert("Total credits cannot equal zero.");
return;
}
// show total
gpa.value = Math.round((totalGradePoints / totalCredits) * 10) / 10;
}

(Note: the sample attaches an onclick event handler to your button in the JS and not by using an onclick attribute. Though, the latter way should work.)
So Im having trouble with my form. There are numurous validation techniques set up.
Two of my most obvious problems are an alert that pops upen at the start of the program but should only pop up if an onblur() is activated and my update() function returns a false value.
And aswell, my regular Expressions insist on providing me with false condition when I test them against my strings.
The finished form should validate various information and update values placed in the expenses inputs.
Really stuck on this...
window.onload = initPage;
/*initPage()
Initializes the contents of the Web page */
function initPage() {
//declare array variable dataFields points to input elements from the expenseEntry class
var dataFields = new Array();
var allElems = document.getElementsByTagName("*");
for( var i = 0; i < allElems.length; i ++) {
if(allElems[i].className == "expenseEntry") dataFields.push(allElems[i]);
}
//add onblur event that runs update() function whenever focus leaves a datafield.
for(var i = 0; i < dataFields.length; i++) {
dataFields[i].onblur = update();
}
//event handler that runs validateForm() upon submitting the form.
document.forms[0].onsubmit = validateForm;
}
/* testLength()
Tests a field for its length. */
function testLength(field) {
if (field.value.length == 0) {
// Change the background color to white or yellow depending on the lenght.
field.style.backgroundColor = "yellow";
return false;
}
else field.style.backgroundColor = "white";
return true;
}
/* testPattern()
Tests a field for its pattern. */
function testPattern(field, regx) {
if (regx.test(field)) {
field.style.backgroundColor = "white";
field.style.color = "black";
return true;
}
else field.style.backgroundColor = "yellow";
field.style.color = "red";
return false;
}
/* validateForm()
Validates a Web form */
function validateForm() {
var isValid = true;
//testLength function with lname field also for fname, address, and summary to make sure an entry has been made.
if (testLength(document.forms[0].lname) == false) {
isValid = false;}
if (testLength(document.forms[0].fname) == false) {
isValid = false;}
if (testLength(document.forms[0].address) == false) {
isValid = false;}
if (testLength(document.forms[0].summary) == false) {

//must match ACT followed by six digits

{isValid = false;}
//dept field. regx should match DEPT followed by three digits

if (isValid == false)
{alert("Please fill out all required fields in the proper format.");}
return isValid;
}
/* calcRow
Calculates the costs within one row of the travel report */

var lodge = parseFloat(document.forms[0].elements["lodge"+row].value);
var meal = parseFloat(document.forms[0].elements["meal"+row].value);
return travel+lodge+meal;
}
/* calcTotal()

You're testing the DOM element against the regexp, which doesn't make sense. The argument to regx.test() must be a string. You need to use the value of the field:
if (regx.test(field.value)) {
You're setting the onblur property wrong. It should be set to the update function, but you're calling the function at that time. It should be:
dataFields[i].onblur = update;
And you were using the .value property when you called testPattern for the department field. But testPattern expects the argument to be the element, not the value. It should be:
if (testPattern(document.forms[0].department, /^DEPT\d{3}$/) == false)
window.onload = initPage;

calculation all working good.when leave fields empty click calculation show red star required first two column remain not showing help me friends
There is a mistake in the condition you have written for the valueC,valueD, valueE and valueF. You should continue as of valueA and valueA for the remaining too, if you want to achieve the functionality as you are trying to.
But, My Suggestion is to Use http://jqueryvalidation.org/ Plugin for validating the elements. It is very handy to use and customize as required.
Thank you
Check you conditions. small logical mistakes in your conditions. for eg.
if (valueC && !valueD) {
status = false;
$("#spand").show();
$("#spanc").hide();
}
if (!valueC && valueD) {
status = false;
$("#spanc").show();
$("#spand").hide();
}
This will check if either valuec or valued is empty. You are not checking for both empty. You need to add something like this
if (!valueC && !valueD) {
status = false;
$("#spand").show();
$("#spanc").hide();
}
Brother its not a good trick to make your code lengthy. You could achieve your goal by using each function. Below is an example of doing that. Please have a look.
function validate(){
var formValidate = true;
jQuery(form + " select," + form + " input").each(
function (index) {
var input = jQuery(this);
if (input.val() == "" ) {
input.addClass("error");
input.parent().next("td").fadeIn("slow");
}
else {
input.removeClass("error");
input.parent().next("td").fadeOut("slow");
}
if (input.hasClass('error')) {
if (formValidate == true) {
formValidate = false;
}
}
}
);
if (formValidate == true) {
return true;
}
else {
return false;
}
}
exact solution to your answer is below please copy n paste then check.

If you really want to do it in that way consider below validation method.
I assume what you want is to check the input fields are empty or not. what you have done is still unclear to me.
To do a proper validation you need to identify and state what should be checked and how should they handled as well.
function validate() {
var status = false;
var valueA = $("#valuea").val();
var valueB = $("#valueb").val();
var valueC = $("#valuec").val();
var valueD = $("#valued").val();
var valueE = $("#valuee").val();
var valueF = $("#valuef").val();
if (valueA) {
$("#spana").hide();
status = true;
}
else {
$("#spana").show();
status = false;
}
if (valueB) {
$("#spanb").hide();
status = true;
}
else {
$("#spanb").show();
status = false;
}
if (valueC) {
$("#spanc").hide();
status = true;
}
else {
$("#spanc").show();
status = false;
}
if (valueD) {
$("#spand").hide();
status = true;
}
else {
$("#spand").show();
status = false;
}
if (valueE) {
$("#spane").hide();
status = true;
}
else {
$("#spane").show();
status = false;
}
if (valueF) {
$("#spanf").hide();
status = true;
}
else {
$("#spanf").show();
status = false;
}
return status;
}
I have an order form within an HTML table associated to some JavaScript verification logic. The current code works but I would like some enhancements to be implemented.
Currently, pressing the "verify" order button gives me the following output:
Line 0 = 1 Qty Line 1 = 4 Qty Line 2 = 2 Qty
Instead of showing table lines numbers followed by quantity value, I need the text to contain the actual products names. E.g. "Line 0 = 1" → "Apple = 1" …
I cannot really seem to figure it out can someone tell me how to do this?
