JavaScript - Adding Array Indexes Up For A Total
Resolution:
Code: <script type="text/javascript">
function amountTotal() {
var totalDonations = 0;
for (var i = 0; i < amount.length; i++) {
totalDonations += amount[i];
}
document.write(totalDonations);
}
</script>
I have an array in a seperate.js file that I need to step through a FOR loop to grab all these values and add them together. Here is a small sample of the array's: Code: city = new Array(); state= new Array(); zip = new Array(); amount = new Array(); date = new Array() firstName[0]="Nina"; lastName[0]="Largent"; street[0]="88 Regal Lane"; city[0]="Williamsburg"; state[0]="KY"; zip[0]="40769"; amount[0]=125; date[0]="2011-09-18"; firstName[1]="Mike"; lastName[1]="Hart"; street[1]="Da404 Barrow Street"; city[1]="London"; state[1]="KY"; zip[1]="40744"; amount[1]=75; date[1]="2011-09-18"; Here is the loop step through that I have: Code: <script src="arrays.js" type="text/javascript"></script>
<script type ="text/javascript">
function amountTotal()
var totalDonations = 0
for (var i=0; i < amount.length; i++) {
}
</script>
I am stuck on how to grab each amount index and add them together to save them as the amountTotal variable. Similar TutorialsHi All, I need help on how to subtract totalgift if my condition of donateamount is lesser than the totalgift trigger. When the field is selected and the DonateAmount is trigger, I need to subtract the entered amount on the field selected to the TotalGift and put the field selected to zero "0" and TotalGift to original amount which is less than the amount entered on the field selected. I have some code that I created but it doesn't work. My initial javascript to calculate all the total is below assuming that DonateAmount is already selected = 25: Code: /* this function works fine with the set of code*/

Below is what I am trying to do but it doesn't work. If the first input field is selected and user enter amount greater than the TotalGift, alert will pop-up then and the amount entered by the user automatically added to the TotalGift. So what I wanted to do is to subtract the amount entered to the TotalGift so it will go back to the original amount before the addition occurs. I know it is possible but I just can't get the right code. Can you please help? I need to make this done as soon as possible, please!!!!! Code: if ((DonateText < TotC) && (document.getElementById('a').value))
{
alert('Your total designated amount of $' + TotC + ' is more than your donation amount of $' + DonateText + '. Please revise your entry to avoid any processing errors.');
//add if here for all fields focus
if (TotC = "0.00")
{
document.getElementById('a').value=0;
document.getElementById('TotalC').value = TotC; // or perhaps value = "ERROR!"
}
else
{
TotC = TotC - document.getElementById('a').value;
document.getElementById('tota').value = "0";
document.getElementById('TotalC').value = TotC; // or perhaps value = "ERROR!"

}
the problem is that this code returns mistake Code: function del_sel(option)

Good day! I am new in javascript function. I have Javascript code for auto calculate here is the code: Code: <script type="text/javascript" language="javascript">
function autocalearn(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, TotEarn = 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?
{
TotEarn += val; //accumulate
}
}
var tot=Number(TotEarn) + Number(document.getElementById('Amount').value);
oForm.TotEarn.value = tot.toFixed(2);
//oForm.TotEarn.value = TotEarn.toFixed(2); //out
}
</script>
<!--Total Deduction AutoCompute-->
<script type="text/javascript" language="javascript">
function autocalded(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');

}
var field, val, oForm = oText.form, TotalDed = a = 0;
for (a; a < arguments.length; ++a) //loop through text elements

val = parseFloat(field.value); //get value
if (!isNaN(val)) //number?

}
//oForm.TotalDed.value = TotalDed.toFixed(2); //out
var totded=Number(TotalDed) + Number(document.getElementById('Deductions').value);
oForm.TotalDed.value = totded.toFixed(2);
}
</script>
and now my problem is...I have a textbox for the overall total, and i want it automatic subtract the total earn and total deduction.. I will attach my codes for further understanding. Thank you in advance Hello Everyone, I am facing problem with divs indexes persistancy on sorting when browser refreshing. checkout this fiddle once and help me. Sortable-arindam - JSFiddle Here how can i maintain the divs persistancy on sorting when page refreshing. Thanks in Advance Satish Chandragiri Okay so im just doing a little test and this might seem like a really stupid question but i cant figure it out...all i simply want to do is take all those numbers and get the sum then display the sum in a document.write in theory i should get 10 but i dont and idk why i have tried many many things Code: var numbers = new Array(); numbers[0] = 1; numbers[1] = 2; numbers[2] = 3; numbers[3] = 4; thanks I know you can add data to array wiht the push() method but can you add a whole new line as in a = new Array a [1] [1,2,3] so it would create a new line a [2] [4,5,6]; The syntax to the array i think is wrong but you get the question. I want to make a script that will insert all text type inputs into an array. From there I want to be able to call them and edit them. Here is what I have so far and it is not working. var phone1 = '702' var inputArray = new Array(); var inputs = document.getElementsByTagName('input'); inputs; if (input.type == 'text') { inputArray.push(inputs.id); } inputArray.reverse(); inputArray[0].value = phone1; Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code. This does not seem to be working for me though. Here is what I have thus far (in short): Code: <script language="javascript">
var teamNames = new Array(3);
teamNames[0]="South Africa";
teamNames[1]="Mexico";
teamNames[2]="Uruguay";
for (i=0; i<=31; i++) {
document.write("<p>" + teamNames[i] + "<\/p>");
}
</script>
</head>
<body>
<tr><td>Jun 11</td><td><input type="checkbox"
name="teamNames[0]" value="teamAbbr[0]"></td>
</body>
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far. Any help would be great! I've got this little chunk of code running on my freelance portfolio site - on each page (different sections of my portfolio) I have 6 thumbnails and a full sized graphic with some descriptive info, you click the thumbnail and it switches the graphic and other info, that all works fine. But on one page I have some web stuff and I'd like to make the var 'clientinfo' into a link to go to the client's website. I know I need to add an array with the website links, but then I'm not sure how to implement it into the html, I've tried various things I've found on here but I'm not getting anywhere on my own. I know it's something pretty simple (for someone who knows what they're doing) but I just can't seem to grasp it. Can anyone help? the js is like this: $(function() { $(".image").click(function() { var image = $(this).attr("rel"); var title = $(this).attr("title"); var description = $(this).attr("content"); var clientinfo = $(this).attr("clientinfo"); $('#gallery').hide(); $('#gallery').fadeIn('slow'); $('#image').html('<img src="' + image + '"/>'); $('#title').html(title); $('#description').html(description); $('#client').html(clientinfo); return false; }); and then the HTML anchors are like this: <a href="#" rel="images/gallery/web/site1.png" title="Site One" content="This is the descriptive info for site number one" clientinfo="Site One link" class="image"><img src="images/gallery/web/t_site1thumb.png" class="thumb" border="0"/></a> Hi all, I have a div element (i.e. <div id="main">) that contains a number of links, each with white background colors and its top and left style properties set to different values. I need to do several things with the anchors when they are clicked: When a white anchor is clicked, its background color is turned yellow and its coordinates (top and left style property values) are added to an array. The coordinates for a single anchor is to be separated by a hyphen; coordinates for multiple anchors are to be separated by a comma (eg. "0-9,0-18") When a yellow anchor is clicked, its background color is turned white and its coordinates are removed from the array. The values in the array are to be the value for a hidden input element, all separated by commas. I'm a Javascript novice and don't know where to begin. Can someone help me with this? Thanks in advance, Dude-Dastic Dear Coders var amount1=12,345,678.10 var amount1=87,246,125.00 I want to sum amount1+amount2 as 99,591,803.10 Please help I currently have a script setup in HTML that will allow me too input a "Customers ID" and their "Gas Usage". Once those are entered, it will do some calculations and display text stating: > "Customers ID: 1 has gas usage of 50 and owes $100 > > Customers ID: 2 has gas usage of 120 and owes $195 > > Customers ID: 3 has gas usage of 85 and owes $142.5 > > Customers ID: 4 has gas usage of 65 and owes $112.5 > > Total amount of customers is: > > Total amount owed all customers:" **What im having trouble** with is making a running total that will calculate the "Total amount of customers" and the "Total amount owed by customers". All I know is that I may need to add another variable in the script. Code: function Summarise()
{
ID = prompt("Enter a Customer ID number ", -1)
while(ID != -1)
{
var gasUsed = 0
gasUsed = prompt("Enter amount of gas used ", "0")

Quote: The parameter A should display the sum of the remaining six fields. I did try adding that using the JAVA script that is mentioned in second code. The total should be display immediately after value is set for any of the text boxes. The text box gets the value using drop down menu. This procedure only works if I use the keyboard tab. If I use the mouse to select YES and No, then it will not display the total Code:

Hi, I admit from the start, I'm not very good with JS, I've used it a few times over the years, but mostly readymade scripts that I can just link to a website and use. Anyway, I need something somewhat specific and I don't know where to find such a code or even if I can modify the one I have found to do what I need. What I need is to be able to update totals on the page as things are changed, but I'm not talking about one total. What I have is a list of spare parts with a quantity box next to them, when someone changes the quatity the price for that part needs to update as well as the total price AND a sum that is an allocated amount minus the total (so they can see how much of their allocation they have left). So far, all I've managed to find is a script that will update just the final total (http://www.mcfedries.com/JavaScript/OrderTotals.asp), but as you can see, that's not that helpful. I've sat and stared at the code and while I can say what things do what, I wouldn't know where to start in changing it. Hope someone can help!
