Calculate Combined Value Of Html Fields, Printing Value To Another
Jan 29, 2010
I have a few html fields in a form that use PHP in order to calculate a combined value and then inserting it into the database. However, I would want that value to be displayed to the user as well before they insert it, just so they can verify that the value is correct. But how do I go about and do this?
It is probably very simple, but I'm a PHP programmer and have very little knowledge of JavaScript. Basically this is what I would want:
<field 1> -20 +(or -, depending on user input) <field 2>
Result of that to be displayed in <field 3>
However, I only want the -20 to calculated when something is entered in <field 1> so that it does not say -20 in the output field before the user even started typing a value.

Is there any way that one could have supersubs functionality applied to drop-down multi-column menus?I assume one would need to calculate the width of each column plus the combined width for the container.

I've created the code below which automatically adds two fields together (drop-down boxes),without the need for a submit or input button.Now,I am trying to do the same again, but this time instead of having drop-down boxes,i need to have text input boxes.(eventually i will be adding monetary values together).

<script type="text/javascript"><!--
function updatesum() {
document.form.sum.value =[code]......

I have a form where I have to calculate a future date (end date) from two fields. First the start date and then the number of months. So if the start date is 1/1/2011 and the months given is 12 then the end date should return as 12/31/2011. I can't figure out why it's not returnign a value.

I am trying to calculate text fields from results of php query. My fields come from the query as amount1, amount2.... What I need is for JS to Sum those fields dynamically, I already did code for when i have all the values and for when the text field name is the same, but never for query results where the names are different. This is what I have so far but its not working
function calculatesumexcon() {
var a, total = 0;
var countJS = "<?=$count?>"; <-- variable of php that gives me the number of rows I am getting on the query
var i ;
for ($i=0;$i<countJS;$i++){
var elements = document.getElementsById('amount' + i);
for(a=0; a<elements.length; a++){
total += (parseFloat(elements[a].value));
}}
document.getElementById("totalextracon").value = total ;
}

I have many html files, and I hope I could print those files in a row.
Is this possbile to print a lot of html files(which are on a web server)
in a row with just one button click javascipt?
It's almost impossible to show as one html page to users, because that's
too big.

i'm using refreshhit for some random quotes pages in different DIVS, and love it;
problem is, if i add html to the text in the pages:
$string = "<a href="page">text</a>";
echo $string;
that's exactly what i'm getting, "<a href="page">text</a>", instead of parsed html - what to do to parse them...?

The following is a JS ticker.It works well, but I can't figure out why the text in italic tags is being printed with the tags, instead of becoming italicized.example is here:
[URL]
Code:
<div>
<span id="tick"><a href="#">Â </a></span><span id="cursor"><img src="http://www.sposa.com/images/feedicon.gif" border="0" alt="_" height="10" width="8" /></span>
<script language="javascript">

I have a form in which a user can create from 1 table to 10 tables which will dynamically create 2 HTML radio buttons, 12 checkboxes and 1 select drop down and 7 input textbox per table in JavaScript.
I need help with printing the whole form with currently filled values.I tried window.print() but it only prints which is visible on the screen. It doesn’t print the bottom section which you have to scroll down to view.
I also tried the following code as well but it prints radio buttons, checkboxes and select drop down with default value, not with the values currently selected or checked.
function CallPrint()
{
var answer = confirm("Do You Want to Print The Case?")
if (answer)

I want to print a html page which has contents wrapped in several div tags. I need to insert page break after each div tag and the page numbers need to start from one, after each page break. I could insert page break using the following java script code.
var allDivs = document.all.tags("div");
for (i=0; i<allDivs.length; i++) {
allDivs(i).style.pageBreakAfter = "always";
}
But the page number is continuous. How can I change the page number for each pagebreak?

I have a program that allows the user to input a product number from 1 to 5, and the amount of each product number sold. After all values are added, the program is supposed to calculate each product's total retail value, as well as the total retail value of all five products combined. The program runs fine, up until the end. I got all my alert boxes working, and the program is doing the multiplication as it is supposed to. However, when I get to the end, I receive "Last weeks total retail sales are: $NaN".
My code:
var productNum;
var quantity;
var prodPrice1 = 2.98;
var prodPrice2 = 4.50;
var prodPrice3 = 9.98;
var prodPrice4 = 4.49;
var prodPrice5 = 6.87;
var total1;
var total2;
var total3;
var total4;
var total5;
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity1 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity2 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity3 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity4 = window.prompt( "Enter the quantity sold" );
productNum = window.prompt( "Enter a Product Number (1,2,3,4,5):", "1" );
quantity5 = window.prompt( "Enter the quantity sold" );
total1 = document.writeln("Total for product 1 is $" + (prodPrice1 * quantity1) + "<br />");
total2 = document.writeln("Total for product 2 is $" + (prodPrice2 * quantity2) + "<br />");
total3 = document.writeln("Total for product 3 is $" + (prodPrice3 * quantity3) + "<br />");
total4 = document.writeln("Total for product 4 is $" + (prodPrice4 * quantity4) + "<br />");
total5 = document.writeln("Total for product 5 is $" + (prodPrice5 * quantity5) + "<br />");
document.writeln( "<h1>Last weeks total retail sales are: $" + ( total1 + total2 + total3 + total4 + total5) + "</h1>" );

I'm trying to make a username form validation combined with ajax but I'm stuck at 1 point. I need to use a var that is outside of my $.get() function so that I can add the function to the validate plugin.
This is what I have:
As you can see, I'm trying to change the value of "var result" to true, but since that is outside of my $.get() it doesn't seem to happen. I tried to put the return command inside the $.get function, but then my validator always keep saying it's a false check.
Is there anyway I can call that var inside my $.get function?

I'm not very experienced with jQuery yet and after a while of trying and searching I decided to ask for help here:
I'm using jCarousel Lite, the "Custom Widget" scenario (click in the list on the left)[url]
When clicking on a image in the carousel, the larger image is shown immedeately. I'm trying to achieve a fadeout, fadein effect. Doesn't need to be a crossfade, a fade out to white, fade in from white is fine.
My 'bare' code (this works, with instant showing of pictures, without any fades)[code]...

I was developing a site search for someone and I got it fully functioning-- the php calls on the input field with #searchField.All the user has to do is begin typing and the results appear underneath without ever having to click submit or enter/return.However, the customer was wondering if I could integrate the Wolfram Alpha Computational Search as well.So that a page visitor or user would type in the search field the results searching his site would appear below, as mentioned above; but, if one typed a query and hit enter then it would search WolframAlpha.I first made a page, here, that uses the code Wolfram Alpha's developer community was giving to developers that creates an input field and searches wolfram Alpha one hits enter. (It writes the necessary html in a messy way and includes this base.css file)Here is a screenshot of the html code that the wolframAlpha.js file writes from chrome dev tools.
After doing so, I put the code of the page I developed for my client and the above page together and what I got was two separate input fields, one that searches the site (top, but it doesn't work due because I did not attach that file as where this is located can't parse PHP) and one that searches wolfram alpha (bottom -- does work).You can see the result of the combined code here.
