JavaScript - Change Calculator And Checkboxes
Hi, I basically want my program to do this.
Show a checkbox list with names of the coins. The user picks the coins he/she has and presses submit. Then prompt boxes show up asking how many toonies you have (if the user selected toonies) and it does that for each one that has been checked marked. I've tried this Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Change Calculator</title>
</head>
<body bgcolor="lightgreen">
<center>
 
<h1>What coins do you have?</h1>
<html>
<form name="form1" onsubmit="return validate(this)">

Thanks for reading! Kevin Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ... Here's my code .... In the <head> Code: <script type="text/javascript">
function getRBtnName(GrpName) {
var sel = document.getElementsByName(GrpName);
var fnd = -1;
var str = '';
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
}
return fnd; // return option index of selection
// comment out next line if option index used in line above
// return str;
}
function chkrads(rbGroupName) {
var ExPg = [
[0,''],
[100,"1 extra page"],
[200,"2 extra pages"],
[250,"3 extra pages"],
[300,"4 extra pages"],
[350,"5 extra pages"]
];
var ExEm = [
[0,''],
[10,"1 extra email"],
[20,"2 extra emails"],
[30,"3 extra emails"],
[40,"4 extra emails"],
[50,"5 extra emails"]
];
var ImgBun = [
[0,''],
[10,"3 extra image"],
[20,"5 extra images"],
[30,"7 extra images"],
[40,"10 extra images"]
];
var rbtnGroupNames = ['extrapages','extraemail','imagebundles'];
var totalprice = 0;
var tmp = ''; var items = [];
for (var i=0; i<rbtnGroupNames.length; i++) {
tmp = getRBtnName(rbtnGroupNames[i]);
if (tmp != -1) {
switch (i) {
case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break;
case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break;
case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break;
}
}
}
document.getElementById('QUOTED_PRICE').value = totalprice;
document.getElementById('ITEMS_SELECTED').value = items.join('\n');
document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice;
}
function validate() {
// add any required validation code here prior to submitting form
var allOK = true;
// if any errors found, then set 'allOk' to false;
return false;
// after testing with validation code, change line above to: return allOK;
}
</script>

ANY help is GREATLY appreciated! already solved
Hi there, me again. Need help with this bit of code. The script itself I got from the JS Source, and modified it myself a bit so that instead of the user inputting their DOB via a prompt box, it could be entered via dropdown lists. I attempted to do this, but have come across a problem. For some reason, the result always (or at least, that's what it looks like to me) appears to be the array index element of [4], i.e. Friday. Not really sure why this is, but no matter what date is entered out of the example dates shown below in the HTML, the result is always Friday. Double-checked on another similiar calculator script online, and sure enough, the results are wrong. So it's a problem with my script. Except I can't identify it. So any help from Old Pedant/Philip M, or whoever else on the forum has the patience to help me , would be much appreciated. Code: <script type="text/javascript" language="javascript">
function findDay() {
var arr = new Array();
arr[0] = "Monday";
arr[1] = "Tuesday";
arr[2] = "Wednesday";
arr[3] = "Thursday";
arr[4] = "Friday";
arr[5] = "Saturday";
arr[6] = "Sunday";
var selectdate = document.getElementById("selectdate").selectedIndex;
var selectmonth = document.getElementById("selectmonth").selectedIndex;
var selectyear = document.getElementById("selectyear").selectedIndex;
var birthday = new Date(selectdate + selectmonth + selectyear);
var day = birthday.getDay();
document.getElementById("div1").innerHTML = "You were born on a " + arr[day] + "!"
}
</script>
Code: <html> <h1>Day Of The Week?</h1> Input your date of birth, and click the Go button to find out what day of the week you were born on. <hr/> <form style="text-align: center;"> <select id="selectdate"> <option>1</option> <option>2</option> <option>3</option> </select> <select id="selectmonth"> <option>January</option> <option>February</option> <option>March</option> </select> <select id="selectyear"> <option>1995</option> <option>1996</option> <option>1997</option> </select> <br/> <br /> <input align="middle" type="button" value="Go" onclick="findDay()"> </form> <div id="div1"></div> </html> I'm decent at JavaScript but I have no idea how I should go about making a calculator. So far I'll drop a bunch of buttons down that all onclick to a function (a,b) and then it will add or w/e then return. How would I incorporate multiple methods such as subtraction or multiplication though? Basically I'm confident I the ability to code or learn to make this calculator, just have no idea how to set this up, thanks. aaaaaa
Hi all master and expert coders I am working on a calculator which using the instructor's codes from the school. The problem that I having right now is the operator.

I am trying to make it so my calculator is disabled on startup. I can only seem to get my textbox disabled but I need everything disabled except the ON button.. so whey they click the ON button everything is enabled. when they click the OFF button everything is wiped and disabled.. I'm not to familiar with that yet so all the help is greatly appreciated.. I'm not sure if I'm going on the right direction with this but heres my code... Code: var value
function start() {
form1.tb1.disabled = true;
}
onload = start;
function enable() {
form1.tb1.disabled = false
}
function shownumber(value){
document.form1.tb1.value=document.form1.tb1.value+value
document.form1.plus.disabled=false
document.form1.minus.disabled=false
document.form1.times.disabled=false
document.form1.divide.disabled=false
}
function showoperator(value){
document.form1.tb1.value=document.form1.tb1.value+value
}
function evalit(){
document.form1.tb1.value=eval(document.form1.tb1.value)
}

I'm currently revamping a website that was written in aspx. The problem i'm having is that the webpage is moving to a hosting company that doesn't support asp. I'm wanting to rebuild the calculator in javascript, however I have no javascript experience. I can figure some parts of the code out, however I don't really have time to learn it, and was wondering if someone would be willing to help. The site i'm trying to change is: http://sunflowertitle.com/ratecalculator.aspx It shouldn't be that difficult to rebuild as its not a detailed calculator. I have all the original files if anyone needs them, i've been working on this for awhile and i'm to the point i'd be willing to pay someone to build it. i am building/coding a simple calculator and i have this Code: function addDigit() {
if(id=7) {
document.getElementById("display").value="7";
}
if(id=8) {
document.getElementById("display").value="8";
}
if(id=9) {
document.getElementById("display").value="9";
}
}
function clearAll() {
document.getElementById("display").value="";
}
as the code but when i press the 7 8 or 9 buttons it only shows up as a 9. go to http://www.mightypeacock.com/Practice/calculator.html to see what i mean. |
