Thanks to this forum, I finally got my calculator working and want to share it with everyone who can use it. The code below divides the time input by the distance input and displays the resulting pace in a min:sec format. Enter 12 miles, for example, and 1 hour, 33 minutes and 15 seconds, and the code displays 7:46 mpm (minutes per mile). My first version uses one function to do everything, but this morning I decided to teach myself how one function passes stuff to another. So I began trying to perform the min:sec conversion in a function named Pace2minsec and pass the result to the Pace function for display in the form. After several failures, I learned that a function returns its calculation to whatever code calls it. Ah ha, I thought, I need to have Pace call Pace2minsec. Yeah, pretty basic stuff but I am a raw beginner with Javascript, and thought there might be others here like me who could benefit from my mistakes. Even after discovering the call-return process, I had to get the names of the variables correct before it would work. One mistake I made was thinking that I could have a variable with the same name in both functions. Wrong. Even though they were both inside their own function and therefore local variables, apparently, since one function called the other, the names had to be different. In both functions, I had a variable named totalsec, but only when I renamed it totalseconds in the first function did my code work. Another glich was discovering that I had to tell the second function what variable it had to use for its operation. My first stab at that was to put the line Pace2minsec(minsec) in the first function. Wrong. Then I tried Pace2minsec(totalsec). Wrong again. And finally, Pace2minsec(totalseconds) which worked fine. Probably obvious to most, but it sure wasn't to me. Trial and error scripting! But I'm getting there, one principle at a time... <CODE> <html> <head> <script> function Pace(D, H, M, S, form) // Is form really necessary? { var dist = parseFloat(D); // Makes entry a number? var hours = parseFloat(H); var mins = parseFloat(M); var secs = parseFloat(S); var pacedecimal = (hours*60 + mins + secs/60) / dist; // Total minutes in decimal var totalseconds = pacedecimal*60; // Total seconds in decimal form.pace.value =Pace2minsec(totalseconds) + " " + "mpm"; // Tell Pace2minsec what variable to use? } function Pace2minsec(totalsec) { var minsec = ''; sec = Math.round(totalsec%60); // remainder of totalsec div by 60 min = Math.round((totalsec-sec)/60); // total seconds minus remainder minsec = min + (sec>9?":":":0") + sec; // min:sec format adds :0 if sec<10 return(minsec); // Pass min:sec format to Pace, the calling function } </script> </head> <body style="margin-top:100px; text-align:center; font-family:arial; background-color:silver;"> <form name="pacer"> <table style="font-size:14px; font-weight:bold;" cellspacing="0" border="0"> <tr> <td>DIST</td> <td><input type="text" name="dist" size="3"></td> <td width="8"></td> <td>TIME</td> <td><input type="text" name="hours" size="1">:</td> <td><input type="text" name="mins" size="1">:</td> <td><input type="text" name="secs" size="1"></td> <td width="24"></td> <td><input TYPE="button" VALUE="Pace" onClick="Pace(this.form.dist.value, this.form.hours.value, this.form.mins.value, this.form.secs.value, this.form)"></td> <td width="4"></td> <td><input type="text" name="pace" size="8"></td> <td width="6"></td> <td><input TYPE="reset" VALUE="Clear" onClick="clearForm(this.form)"></td> </tr> </table> </form> </body> /html> </CODE> I'm making a calculator with javascript inside of my html, but I can't figure out the right way to produce a working ^ sign.

This is a code for a simple calculator that requires the input of an Area and then calculates how many packs of product are then required to cover that area, rounding up to the next full pack, The results should be displayed in a simple HTML form but its not happening. I can't see any obvious errors. Am I missing something. Any help or ideas would be greatly appreciated. I might be making this more complicated than necessary. Thanks In the <HEAD> Code: <script>
function packCalculation(){
if ( document.getElementById('coverage').value == '' )
{
alert('You must enter a number')
return false;
}
var coverage = parseFloat(document.getElementById('coverage').value); //declare coverage variable-->
if (isNaN(coverage))
{
alert('Please only enter numbers')
return false;
};
var coverage = parseFloat(document.getElementById('coverage').value);
var packSize = parseFloat(document.getElementById('pack-size').innerHTML);
var price = parseFloat(document.getElementById('price').value);
var packNumFinal = coverage/packSize; <!--work out how many packs are needed-->
var finalPrice = packNumFinal*price; <!--work out final price -->
document.getElementById('packsNeeded').innerHTML = packNumFinal.ceil(); <!--round up to the next full pack-->
document.getElementById('calcPrice').innerHTML = parseFloat(finalPrice).toFixed(2); <!--fix to 2 decimal points-->
document.getElementById('results').className='show';
return false;
}
</script>

ANY help is GREATLY appreciated! This is what I have so far, but now I am stuck. My instructor wants the output value (Number Set C) to include Number Set A and Number Set B. For instance, if Number Set A is "10" and you want to add Number Set B whose value is also "10", my instructor wants Number Set C to say "10 + 10 = 20". Where am I going wrong, and what is the easiest way I can make this work while making as little changes as possible? Most of the code is what my instructor requires us to use. Code: <HTML>

Hi everyone, I am currently doing a project with a calculator and I am having a bit of trouble trying to figure something out and was wondering if I could get some help with it or possibly even a good site to read up on it. 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)

Hello guys, long story short my boss wants me to add this calculator form to our website(here is the link to what he wants exactly) so I try to copy that code but it won't work. I was wondering if this javascript would work. Code: Code: <script language="JavaScript">
function calc() {
gear = document.name1.drpPumpType.1;
vane = document.name1.drpPumpType.2;
if (gear)
{
txtW = document.form1.txtW.value;
txtD = document.form1.txtD.value;
txtL = document.form1.txtL.value;
int gearCIR;
gearCIR = 6 * txtW *(2 * txtD - txtL) * (txtL - txtD) / 2;
}
else
{
int vaneCIR;

I probably don't even need a if statement but I haven't program in a long time and never use java script before. so bare with me. here is the html form code Code: Code: <form name="name1"> <table align="center" border="0" width="44%"> <tbody> <tr> <td colspan="3"><span class="BoldHeadingLabel style1">Displacement from Measurements</span></td></tr> <tr> <td width="50"><span class="style1"></span><br /> </td> <td width="157"><span class="BoldLabel style1">Pump/Motor Type:</span></td> <td width="456"> <span class="style1"></span> <br /> </td></tr> <tr> <td width="50"><span class="style1"></span><br /> </td> <td width="157"><span class="BoldLabel style1">Gear Width (W):</span></td> <td><span class="style1"><input name="txtW" id="txtW" maxlength="10" size="10" value="" type="text" /></span></td></tr> <tr> <td width="50"><span class="style1"></span><br /> </td> <td width="157"><span class="BoldLabel style1">Gear Bore Dia.

I copy this code from that website. but can't find any code wrong. I know this code is probably so wrong but any help is much appreciated . I want the calculator to take what was clicked display the item number and also the cost. (if possible i'd like to be able to display cost with no button) sorry if the code is messy i'm new to javascript. Code: <SCRIPT TYPE="TEXT/JAVASCRIPT">

I don't know if anyone can help me with this? Each numeric button should change the input box up at the top to whatever. When one of the operator buttons (+,-,*,/) is pressed, the value in the input box at the top should change to 0. Before an operator button is pressed, the value should be stored in a variable to keep track of the left-hand side of the equation. After it is pressed, the value should be stored in the right hand side variable.

I have a mistake when it is suppose to calculate. Thanks to all I have my first ever scholastic JS assignment and so far it's felt nearly impossible to get a grip on how to do it. I've gone through the W3c tutorials entirely 3 times now and still, nothing is clicking mentally. Generally I do better if I can reverse engineer already written code but I can't find anything similar enough to this on the net to figure it out. The assignment is to create a grade averages calculator as seen in this pictu Along with this starter code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I understand what I need to do, just not the syntax to do it. Any help would be appreciated. Sorry for newbiness. 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. I have a formula done in PHP. Lets say it's PHP Code: $sum = $_POST['one'] + $_POST['two']; I have 2 textboxes, one named "one", the other named "two". I want the page to also display the answer under the text boxes but it updates in real time when you input a value into the textboxes. How would I do that? |
