JavaScript - Rent Proration Calculator
I have been looking online for something I can use to calculate:
Base Rent + Pet Rent + Parking Rent+Tax=Total Monthly Rent I would like the tax to be automatically calculated and shown so we can print the page and see all of the values. Along with this I am trying to have it calculate the amount it costs per day for that specific month they move in (28/30/31 days) and also the total amount for the number of days they will be there for that month, all by entering their move in date. I am looking for pretty much anything from html and java and either excel or word documents. Any help would be great! Thanks Nik Maybe something similar to this... Not completely the same can be different. http://www.geocities.com/nikschultz/Untitled.html Similar TutorialsI have everything working up to this point but when I try and put the math equation into my script section, I get multiple error and cannot figure out how to get the function to return the actual total rental cost. If you could please look at what I have, your opinions would be greatly appreciated. Thank you. Below is the code with the math function at the end of the script section in the heading which I seem to be receiving error on. Any help is greatly appreciated. Thanks. Code: <!DOCTYPE html PUBLIC

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">

already solved
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;
vaneCIR = 12 * txtW * (txtL + txtD) / 4 * (txtL - txtD) / 2;
}
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'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'm not sure what the code is to add this to 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. Thanks So after some studying I have a pretty decent method using objects. I built it so that you hit the first number, then you would hit a plus or minus then the second number. The problem is just getting the buttons to define variables and run functions. Quote: <html> <head> <script type="text/javascript" > x=10; h=1; var numbs = new Const(x) function Const(one){ this.x=one; ADD(this.x) if(h=1){ function ADD(a){ y=5; b=y+a; alert(b); }}} </script> </head> <body> <input type="button" value="1" onclick="needs to run all that AND set x=1 and h=1"> </body> </html> Also I plan on going back and making y, which is the second number you're adding, an object. For now I'm just setting it equal to something so I don't have to mess with it. I need help trying to figure out how to get my bmi calculator to work. I cant figure out what is wrong with my formula part and why it wont calculate the numbers you type in...pls help! <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <script type="text/javascript"> function calculateBMI() { var weight = numb(document.data.weight.value) var height = numb(document.data.height.value) var height2 = height2 * height2 var BMI = weight * 703 / (height2 * height2) document.form.BodyMassIndex.value=custRound(BMI,1); } </script> <title></title> <style type="text/css"> div.c2 {text-align: center} input.c1 {font-size: 8pt} </style> </head> <body> <div class="c2"> <form name="form" id="form"><input type="text" name="weight" size="4"> Weight (in Kilos) <input type="text" name="height" size="4"> Height (in Centimeters)<br> <br> <input type="text" name="BodyMassIndex" id="BodyMassIndex" size="4"> BMI <input type="button" class="c1" value="Calculate" onclick="calculateBMI()" name="button"> <input type="reset" class="c1" value="Clear Form"></form> </div> </body> </html> 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. 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 have been having problems adding checkboxes and option selects in the same function.. Here's what I have. Code: <script type="text/javascript">
function bonuscalc() {
var aaaa = document.getElementById("aaaa").value;
var bbbb = document.getElementById("bbbb").value;
var cccc = document.getElementById("cccc").value;
if (dddd.checked){
var dddd = document.dddd.value = 2;
}
else {
var dddd = document.dddd.value = 1;
}
var eeee = document.getElementById("eeee").value;
var bonus = aaaa* bbbb * dddd * cccc * eeee;
var roundbonus = Math.round(bonus*10)/10;
document.getElementById("roundbonus").value = roundbonus;
}
</script>
Javascript first.. The part I'm not sure about is the if/else part for checbox. Now the html: Code:
<form action="" id="calc1">
<table width="100%">
<tbody>
<tr>
<td>A status: <select id="aaaa">
<option value="1.1">A1</option>
<option value="1.02">A2</option>
<option value="1">A3</option>
<option value="0.95">A4</option>
</select>
</td>
<td>B status: <select id="bbbb">
<option value="1">0%</option>
<option value="0.99">1%</option>
<option value="0.98">2%</option>
<option value="0.97">3%</option>
<option value="0.96">4%</option>
<option value="0.95">5%</option>
<option value="0.94">6%</option>
<option value="0.93">7%</option>
<option value="0.92">8%</option>
<option value="0.91">9%</option>
<option value="0.90">10%</option>
</select>
</td>
<td>E status:<input id="eeee" type="text" />
</td>
<td>D status: <input id="dddd" name="dddd" type="checkbox">
</td>
<td>C status: <select id="cccc">
<option value="1">No</option>
<option value="1.2">Yes</option>
</select>
</td>
</tr>
<tr>
<td width="100%">
<input type="button" value="Submit" onclick="bonuscalc()" />
<br />
Result: <input type="text" readonly="readonly" id="roundbonus" />
</td>
</tr>
</tbody>
</table>
</form>
I hope it's not too confusing. The idea is to assign value 2 if the checkbox is checked and value 1 is it isn't.. 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">
// Definitions
var in2 = ""
var in3 = ""
//costs
var $mat = ""
var cmat = Number($mat)
var $sqft = ""
var csf = Number($sqft)

var $coga = 30
var $cos = 40
var $coshp = 15
var $total = chngcost + $coga + $cos + $coshp
// Add a letter to string
function itemnumber2(numb) {
in2 = numb
document.myform.i2.value = in2
document.itemnumber.i2.value = in2
if (in2 == "10") {
$mat = 3
document.myform.cmat1.value = $mat
}
if (in2 == "11") {
$mat = 6
document.myform.cmat1.value = $mat
}

}
function itemnumber3(numb) {

document.myform.i3.value = in3
document.itemnumber.i3.value = in3
if (in3 == "1") {
$sqft = 7.5
document.myform.sqrf1.value = $sqft
