GetElementByID With Calculation - Getting The Previous And Current Reading To Subtract Each Other And Post In The "kwh Used" Column
Mar 18, 2011
I'm making a form for my rural neighbors' electricity calculations. My main problem is getting the Previous and Current reading to subtract each other and post in the "kwh Used" column. My plan is to continue doing the calculations after I find that value. Here is the code thus far:
<head>
<title>Untitled Document</title>
<script language="javascript">
function calc()
{
preR= Number(document.Bill_cal.PrRe.value);
[Code]...

I have the following function that will subtract n number of days from todays date. The problem is that it always returns the the wrong calculate date. The month is wrong.
see if you can spot my mistake:
Code:
function returnDate(ndays){
var dayOfTheWeek = now.getDay();
now.setTime(now.getTime() - nDays * 24 * 60 * 60 * 1000);
alert(now); // returns current date
alet(now.getYear() + "/"+now.getMonth()+"/"+now.getDate()) // returns new calculated date
}

I keep getting an object expected error at the start of my <body>I've set a form to value="Accountants" and <body onload="showindex()"> in an attempt to automatically submit this value to a js file whenever the page loads. My aim is to have dozens of html pages all using the same js file to return information based on the contents of that value.
Code is below
index.html
<head>
<script src="AccountantsLoad.js"></script>
[code]...
I'm probably not submitting the form value correctly or the js file 'url' variable isn't being put together right.

I have a issue with a javascript code that I wrote. This script is a simply for calculating the summation of 2 text input boxes and printing it in another text input box within the form. The entire form is then sent using Form post.The total is written back to the form's total text input box using the code below:
document.getElementById ('total').value = total
This code works perfectly for displaying the values on screen. However, when I send the form (PHP Post), the " total " field is empty. I have searched all over for possible solutions. But no solution yet.
1. document.getElementById ('total').INNERHTML = total .This does not even work on screen and total field is not updated on screen. Needless to say, the PHP Post variable was also empty.

Heres my most current code. I have it where, onClick on an image it calls this. and it works, but the hp keeps restarting, like they all minus from 100, instead of the number that prieviously minused from 100. For xp: 100-9=91, is the first, the second, 100-72=28 instead of 91-72. How do i fix
var myhp;
function takehits()
{
var dmg= new Array()
dmg[0]=9;
dmg[1]=11;
dmg[2]=15;
dmg[3]=21;
dmg[4]=29;
myhp=100;
var rndtake=Math.floor(Math.random()*5);
document.getElementById('health').innerHTML=myhp-dmg[rndtake];
}
I want to have it where, you have an aray, and u have a number value that you want the number value, to be subtracted by one of the numbers in the array. And u lets say the array has 5 choices. Code:

Am i breaking any rules when I loop dates like
// Determine Memorial Day
intFlag = 0;
memDayHol = new Date (currentYear, 4, 31);
while (intFlag == 0) {
if (memDayHol.getDay() == 1) {intFlag =1;}
else {memDayHol = memDayHol - 1;}
}
I can find no docs that one can use the '+' operator directly on a date
object, and it assumes adding/subtracting a day(s). Is this deprecated
code?

I am trying to change the script below from adding the values to subtracting without much luck.
Code:
<script type="text/javascript" language="javascript">
function autocalc(oText) {
if (isNaN(oText.value)) //filter input {
alert('Numbers only!');
oText.value = '';
} var field, val, oForm = oText.form, netincome = a = 0;
for (a; a < arguments.length; ++a) //loop through text elements {
field = arguments[a];
val = parseFloat(field.value); //get value
if (!isNaN(val)) //number? {
netincome += val; //accumulate
}}
oForm.netincome.value = netincome; //out
}
</script>

I have an image gallery where every image has an index number ("data-index"). How do I access that index number when the image is "current" and then add +1 when it's "next" or subtract -1 when it's "previous"? Below is part of my code.

Take a variable...
var time = "12:00"
split it...
var hour=time.split(":");
...then add or subtract from the numeric value of hour[0] based on timezone.
EST = -5
PST = -8
What would be the best way of doing this?

What Ive done is use local storage to set a value in my web app.
Then my next task was to write said value on my page (This took me hours but finally got it done).
My next task is using Setinterval(or what ever the correct way to solve my problem) to subtract a number (lets use "1" for this example) Every 5 seconds from the local storage value.So basically After I click the button. Value is set and displayed. After another button is click. Every 5 seconds the localstorage is subtraced by 1. I think the code im looking for is similar to this

jM(document).ready(function(){
// Calculator behavior
//Addition Time!
jM(".add").click(function() {

jM('.subtract').click(function() {
alert('test');
});
});

I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.

I have created a PDF time sheet for work that automatically calculates the hours worked utilizing the below script:
topmostSubform.Page1.worked[0]::calculate - (FormCalc, client)
var amTime = 0
if (HasValue(amOut) and HasValue(amIn)) then
amTime = Time2Num(amOut.formattedValue, "h:MM A") - Time2Num(amIn.formattedValue, "h:MM A")- 1800000
endif
// compute total time in hours from the millisecond value
$.rawValue = Sum(amTime)/3600000
I discovered a problem; if the employee works less than 8 hours they may not take a lunch. I have it set to automatically subtract 30 minutes for lunch. How do I write it to only subtract 30 minutes if the work day is greater than 4 hours? I am new to java script and have NEVER programmed anything previously. I am working in Adobe LiveCycle Designer and what I have done so far was gleaned by reading the internet. So please, if you reply break it down Barney style.
