JavaScript - Adding Textbox Numbers Summing Problem
Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section. What am I doing wrong? Thank you for your time and help.
Code: <script type="text/javascript"><!--
function updatesum() {
document.frmtotal.total.value = parseInt(document.form1.basic.value) + parseInt(document.form2.supporter.value)}
//--></script>
<tr>
<td width="111"><form id="form1" name="form1" method="post" action="">
<label for="basic">$</label>
<input name="basic" type="text" id="basic" size="7" maxlength="7" onchange="updatesum(this.form)" />
</form></td>
</tr>
<tr>
<td><form id="form2" name="supporter" method="post" action="">
<label for="supporter">$</label>
<input name="supporter" type="text" id="supporter" size="7" maxlength="7" onchange="updatesum(this.form)" />
</form>

Hi, Want to add numbers using JS. Have 4 text boxes for user entry. Want either a label (preferred) or fifth text box to automatically sum those entries. Did following but not working. Any suggestions? <script language="javascript"> var addRange = function() { var NoHrsRangeComp = document.getElementById("NoHrsRangeComp"); var NoHrsRangeCred = document.getElementById("NoHrsRangeCred"); var NoHrsRangeOT = document.getElementById("NoHrsRangeOT"); var NoHrsRangeRC = document.getElementById("NoHrsRangeRC"); var RangeSum = document.getElementById("RangeSum"); var sum = 0; if (isNaN(parseFloat(NoHrsRangeComp.value))){ NoHrsRangeComp.value = ""; } if (isNaN(parseFloat(NoHrsRangeCred.value))){ NoHrsRangeCred.value = ""; } if (isNaN(parseFloat(NoHrsRangeOT.value))){ NoHrsRangeOT.value = ""; } if (isNaN(parseFloat(NoHrsRangeRC.value))){ NoHrsRangeRC.value = ""; } sum = parseFloat(NoHrsRangeComp.value) + parseFloat(NoHrsRangeCred.value) + parseFloat(NoHrsRangeOT.value) + parseFloat(NoHrsRangeRC.value); RangeSum.innerHTML = sum; } </script> Input as follows: <input style="width: 50px" type="text" name="NoHrsRangeComp" id="NoHrsRangeComp" onblur="addRange();"/> <input style="width: 50px" type="text" name="NoHrsRangeCred" id="NoHrsRangeCred" onblur="addRange();"/> <input style="width: 50px" type="text" name="NoHrsRangeOT" id="NoHrsRangeOT" onblur="addRange();"/> <input style="width: 50px" type="text" name="NoHrsRangeRC" id="NoHrsRangeRC" onblur="addRange();"/> <input style="width: 50px" type="text" name="RangeSum" id="RangeSum" onblur="addRange();"/> For above entry prefer - label makes it look more like usual addition and does not confuse users to want to make entry. <label id="RangeSum" onblur="addRange();" style="border-bottom:medium"></label> John Hey, I'm trying to do a homework problem that involves using cookies to add numbers.

The code is simply supposed to prompt the user asking how many numbers he/she would like to add. Then it is supposed to have additional prompts asking for each individual number. As the numbers are being inputted, it is supposed to keep a running sum via cookies and then output the total at the end. The problem that I'm having is that I don't think the cookies are even being created which is weird because the createCookie(), printCookie(), and overWriteCookie() methods are copied directly from the textbook. Any help would be greatly appreciated. Thanks. I have the following code that I wrote myself (except for the function isNumberKey). However, I don't know how to actually add the numbers together. My plan is to store the value entered in the forms as a variable, then manipulate the variables to get my final number. The final number would be stored in variable named Total and would be displayed after Total: at the bottom of my page. Could anyone help me? I can provide additional information if you need it. Code:

I've been looking for a solid solution for how to add numbers to markers. Most that I've seen involve an asp page with a post back of an image based on the query string. I am trying to do something like what MarkerClusterer does. Here is an example: http://google-maps-utility-library-v...e_example.html I've looked over their code and cant seem to pull out the part where it adds the numbers to the marker, I'm still new to jquery. Here is a link to the source code: http://google-maps-utility-library-v...erclusterer.js any help would be appreciated. Hello guys (and girls) I am messing with this whole day, 'cos I wanted to try and figure this out by myself instead of going on forums. I failed, as you may see. So, to cut it short: I needed to calculate my prices on-the-fly and display it in textbox with javascript. Well I did succeed with values of radio button an checbox, but as i know very little javascript, I don't know how to expand the code i got from he http://javascript.internet.com/forms...e-refresh.html So what I would LOVE to know, is how can I make this happen: I have a textbox: Code: <input type="text" name="podstranice" size="19" class="podstr" onkeyup="this.form.total.value=calculateTotal(this);"> and when a user inputs a number in it, javascript multiplies it with some other number, say 10 (its a price*quantity thing) and adds it to the total price along with data from checkboxes and radio buttons. And so, this is my javascript. It is basically identical to one on the link, but you can view it better this way I think. Code: // Calculate the total for items in the form which are selected.
function calculateTotal(inputItem) {
with (inputItem.form) {
// Process each of the different input types in the form.
if (inputItem.type == "radio")
{ // Process radio buttons.
// Subtract the previously selected radio button value from the total.
calculatedTotal.value = eval(calculatedTotal.value) - eval(previouslySelectedRadioButton.value);
// Save the current radio selection value.
previouslySelectedRadioButton.value = eval(inputItem.value);
// Add the current radio button selection value to the total.
calculatedTotal.value = eval(calculatedTotal.value) + eval(inputItem.value);
}
else
{ // Process check boxes.
if (inputItem.checked == false)
{ // Item was uncheck. Subtract item value from total.
calculatedTotal.value = eval(calculatedTotal.value) - eval(inputItem.value);
}
else { // Item was checked. Add the item value to the total.
calculatedTotal.value = eval(calculatedTotal.value) + eval(inputItem.value);
}
}
elseif
// Total value should never be less than 0.
if (calculatedTotal.value < 0) {
InitForm();
}
// Return total value.
return(formatCurrency(calculatedTotal.value));
}
}
// Format a value as currency.
function formatCurrency(num) {
num = num.toString().replace(/\$|\,/g,'');
if(isNaN(num))
num = "0";
sign = (num == (num = Math.abs(num)));
num = Math.floor(num*100+0.50000000001);
cents = num%100;
num = Math.floor(num/100).toString();
if(cents<10)
cents = "0" + cents;
for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
num = num.substring(0,num.length-(4*i+3)) + ',' + num.substring(num.length-(4*i+3));
return (((sign)?'':'-') + num + '.' + cents + ' kn');
}
// This function initialzes all the form elements to default values.
function InitForm() {
// Reset values on form.
document.selectionForm.total.value='$0';
document.selectionForm.calculatedTotal.value=0;
document.selectionForm.previouslySelectedRadioButton.value=0;
// Set all checkboxes and radio buttons on form to unchecked.
for (i=0; i < document.selectionForm.elements.length; i++) {
if (document.selectionForm.elements[i].type == 'checkbox' | document.selectionForm.elements[i].type == 'radio') {
document.selectionForm.elements[i].checked = false;
}

I'm really new to this and I'm trying to figure out how to sum the two values from if statements. ParseInt is returning NaN. Before that, it was adding my results together as strings. Is there an easy way to add these together without creating a very complicated if statement to total these up? Thanks! i have a form with several headings, then for each heading i have a list of items with a select box filled with numbers. For each heading a maximum of items is allowed, so the user should change the values in the dropdowns and not be allowed to continue until they are less than or equal to their maximum limit. To complicate this, there will be more than one headings on the page, but each one with a different name/id. Eg: Heading 1 Title 1 DROPDOWN1 Title 2 DROPDOWN2 Title 3 DROPDOWN3 So here the max is 10, so the values cannot exceed 10 Heading 2 Title 1a DROPDOWN1 Title 2a DROPDOWN2 Title 3a DROPDOWN3 Title 4a DROPDOWN4 So here the max is 10, so the values cannot exceed 14 thanks I'm new to js and have been going crazy trying to get this to work. I need the script to pull the values in the class selected, then spit out the sum of them. It can't be that hard! This is what I have and it just won't run. I'm working in a intra environment, so I'm not too worried about cross-browser compatibility. Any help would be appreciated. Thank you. <html> <head> <script> function findTheOddOnes() { var theOddOnes = document.getElementsByClassName("odd"); for(var i=0; i<theOddOnes.length; i++){ sum += theOddOnes[i].textContent; alert(sum); } } </script> </head> <body> <h1>getElementsByClassName Test</h1> <p class="odd">1000</p> <p>This is an even para.</p> <p class="odd">1000</p> <p>This one is not odd.</p> <form> <input type="button" value="Find the odd ones..." onclick="findTheOddOnes()"> </form> </body> </html> Hello, I'm working on a project that involves extracting values from a series of select boxes and then working out the result. The select boxes contain the following: Code: <select name="select_Col1_Row1"> <option value="blue">Blue</option> <option value="green">Green</option> <option value="red>Red</option> </select> <select name="select_Col1_Row2"> <option value="blue" selected="selected">Blue</option> <option value="green">Green</option> <option value="red>Red</option> </select> <input type="text" name="RedSum"> <input type="text" name="BlueSum"> <input type="text" name="GreenSum"> </select> As you can see by my code, I'm early days at this and guessing the steps on the way. I tried using getElementsByTagName on the select and then on the option but had no luck with that. The code below does a wonderful job of returning blue for both select statements... Code: <script type="text/javascript">
function getElements()
{
var table = document.getElementById("x");
var x = table.getElementsByTagName("option");
for (var i = 0; i < x.length; i++) {
var status = x[i].getAttribute("selected");
alert(status);
if (status == "selected") {
var statushcap = x[i].getAttribute("id");
var statusvalue =x[i].getAttribute("value");
if (statusvalue == "blue") {
alert(statusvalue);
}
}
}
alert(x.length);
}
</script>
If someone could suggest some way to map the select tag and then extract its option value to being the user selected value, I'd most appreciate it. I can probably do the rest of it. Can you extract additional information from the id of the option that is selected as I'd like to sum additional information from the user's choice.

Following are some of the interfaces provided by this plugin: // Interfaces: // x = new BigInt("1234567890123456789012345678901234567890"); // y = new BigInt("0x123456789abcdef0123456789abcdef0"); // z = x.clone(); // z = bigint_uminus(x); // z = bigint_plus(x, y); // z = bigint_minus(x, y); // z = bigint_mul(x, y); // z = bigint_div(x, y); // z = bigint_mod(x, y); // cmp = bigint_cmp(x, y); /* return -1, 0, or 1 */ // num = bigint_number(x); /* convert normal number (may be floating) */ // From the above interfaces , I just need to use bigint_plus and bigint_minus functions for my code. But bigint_minus is not returning the proper subtraction for two big integers. Attached is the BigInt.txt file , before using please rename the file to BigInt.js.apart from bigint_minus functions other functions are working fine for me. Please let me know what is the problem with bigint_minus() function. Thanks, Dinesh Hello. I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? Code: <form name="signup" action="javascript:void(0);" method="post">
<table>
<tr>
<td>Date Of Birth:</td>
<td>
<input name="DOBmonth" type="text" value="MM" size="2" style="color: #555555;" onFocus="clearDOBmonth()" onBlur="restoreDOBmonth()" />
<input name="DOBday" type="text" value="DD" size="2" style="color: #555555;" onFocus="clearDOBday()" />
<input name="DOByear" type="text" value="YYYY" size="4" style="color: #555555;" onFocus="clearDOByear()" /></td>
</tr>
<tr>
<td></td>
<td><button name="Submit" type="submit" style="font-size: 1em;">Sign Up</button></td>
</tr>
</table>
</form>
<script type="text/javascript" language="javascript">
<!--
document.signup.DOBmonth.value="MM";
document.signup.DOBday.value="DD";
document.signup.DOByear.value="YYYY";
function clearDOBmonth() { document.signup.DOBmonth.value="";}
function clearDOBday() { document.signup.DOBday.value="";}
function clearDOByear() { document.signup.DOByear.value="";}
function restoreDOBmonth()
{
if ('document.signup.DOBmonth.value = ""')
{
document.signup.DOBmonth.value = "MM";
// alert(document.signup.DOBmonth.value);
}
}
//-->
</script>
Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example: Code: var a = document.form.textbox.value; a = blue; does document.form.textbox.value = blue? or is var a now completely independent of the textbox value? Thanks! I have the following HTML code: Quote: <form id="registration" action="/cgi-bin/registration.cgi" method="POST" onsubmit="return control()"> <fieldset> <legend>Fill up this module</legend> Private <input id="private" type="radio" name="type" value="private" onclick="return addPrivate()"/><br/> Community/Organization <input id="organization" type="radio" name="type" onclick="alert('Organization')"/><br/> <br/> and the following javascript code: Quote: function addPrivate() { var root = document.getElementById('registration'); var label1 = document.getElementById('label'); label1.appendChild(document.createTextNode('First Name: ')); var label2 = document.getElementById('label'); label2.appendChild(document.createTextNode('Last Name: ')); var label3 = document.getElementById('label'); label3.appendChild(document.createTextNode('Address*: ')); var label4 = document.getElementById('label'); label4.appendChild(document.createTextNode('Profession: ')); var div = document.createElement('div'); div.appendChild(label1); div.appendChild(label2); div.appendChild(label3); div.appendChild(label4); root.appendChild(div); } but div tag is not added. Where is the problem? Hi Guys, Been stuck on this for too long now. I'm trying to write a function that rotates images with a fade. The function work properly, however I can't make the images fade back in. The fadein function won't add to the .style.opacity Here's the code with the php Code: function fadeout()
{
b<?php echo ($AF_list_artist_id->artist_id); ?>.style.opacity = (b<?php echo ($AF_list_artist_id->artist_id); ?>.style.opacity - 0.01);
if(b<?php echo ($AF_list_artist_id->artist_id); ?>.style.opacity == 0.1)
{
clearInterval(fadeouttimer);
b<?php echo ($AF_list_artist_id->artist_id); ?>.src = a<?php echo ($AF_list_artist_id->artist_id); ?>[starter<?php echo ($AF_list_artist_id->artist_id); ?>];
function fadein()
{
b<?php echo ($AF_list_artist_id->artist_id); ?>.style.opacity = (b<?php echo ($AF_list_artist_id->artist_id); ?>.style.opacity + 0.01);
//alert(b<?php echo ($AF_list_artist_id->artist_id); ?>.style.opacity);
if(b<?php echo ($AF_list_artist_id->artist_id); ?>.style.opacity == 1)
{
clearInterval(fadeintimer);
setTimeout("rotate<?php echo ($AF_list_artist_id->artist_id); ?>("+(starter<?php echo ($AF_list_artist_id->artist_id); ?>+1)+")",6000);
}
}
var fadeintimer = setInterval(fadein,10);
}
}
var fadeouttimer = setInterval(fadeout,10);
and without Code: function fadeout()
{
b7.style.opacity = (b7.style.opacity - 0.01);
if(b7.style.opacity == 0.1)
{
clearInterval(fadeouttimer);
b7.src = a7[starter7];
function fadein()
{
b7.style.opacity = (b7.style.opacity + 0.01);
//alert(b7.style.opacity);
if(b7.style.opacity == 1)
{
clearInterval(fadeintimer);
setTimeout("rotate7("+(starter7+1)+")",6000);
}
}
var fadeintimer = setInterval(fadein,10);
}
}
var fadeouttimer = setInterval(fadeout,10);
