Hi gud mng,

I have one problem...

How to process textbox values/ call textbox values in JS through a Java program.
My text box values are dates. I have to process these dates.

Like in online banking we select day to know our transactions. After submitting we get results. remember my files are in my directory only. No need of database.

My files are look like 20100929, 20100930, 20101001

In my coding, ys, ms, ds represents year starting, month starting, starting day...
ye, me, de represents end...

start,end gives file names in the format of yyyymmdd

now i want to process files from 20100101 to 20100930

means from date is 2010/01/01 and to date is 2010/09/30

if i press submit button the files from 20100101 to 20100930 are processes

here ys=2010 ms=01 ds =01 and ye=2010 me=09 de= 30

For this how do i call these textbox values (from date text box and todate) to another program (java)

Thanks in advance.

Very New To Js, Need Help With An Averages Calculator

View Content

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">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Assignments score calculator</title>
<style type="text/css">
<!--
.score {
    width: 30px;
}
-->
</style>
</head>

<body>
<h1>Assignments score calculator</h1>

<form id="calculator" name="calculator" method="post" action="">
<p>Enter your Name: 
  <label for="firstname"></label>
  <br />
  <input type="text" name="firstname" id="firstname" />
<p> 
  <label for="A1">Assignment #1 sco </label>
  <input name="A1" type="text" class="score" id="A1" maxlength="3" /><br />
<label for="A2">Assignment #2 sco </label>
  <input name="A2" type="text" class="score" id="A2" maxlength="3" /><br />
<label for="A3">Assignment #3 sco </label>
  <input name="A3" type="text" class="score" id="A3" maxlength="3" />
<p>
  <label for="button"></label>
  <input type="submit" name="Submit" id="Submit" value="Submit" xx="doCalculation(this.form.firstname.value,this.form.A1.value,this.form.A2.value,this.form.A3.value)" />
</form>
</body>
</html>

I understand what I need to do, just not the syntax to do it. Any help would be appreciated. Sorry for newbiness.

Need Help With Form Calculator

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&nbsp;from&nbsp;Measurements</span></td></tr>

For some reason it says access denied. 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 .

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.

Almost Have My First Calculator Made

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 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'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.
