JavaScript - Help Needed With Javascript Calculation
Hi,
I'm trying to get my head around JS, but not too successfully yet. My objective is probably simple (but not to me ): to have a form where visitors enter 12 separate digits (ideally in minutes & hours, but am happy to use decimals), and the average of these (to two decimal points) is returned as document.write is it? - along with other text, to make a complete & coherent sentence, including the average of the 12 numbers. Does anyone have any code convenient that could do this? Thanks, LJ Similar TutorialsHi everyone, I am new to Javascript and took a class or 2 in college, but need some help. I need to make a calculation for a webpage that will do the following: Client will insert AWG (wire ) Size, then it will derive the correct Circular Mils that the AWG is equal to from an Access Database ( I assume this is the way to set that up or if I can in Javascript itself, thats fine as well ), then Multiply it by the Number of Strands that the Client will also insert. I had this all set up in Visual Basic and working great, and my boss said he does not want it in a pop up box but prefers it on the website itself hence me reverting to Javascript for this. To visualize it Image 2 boxes with AWG and STRANDS that the client will put in, then another box with TOTAL CMA where the answer will pop up after it has multipled by the AWG individual CMA and number of Strands. I have the general idea to set it up, just do not know how to get the Database in there and Code it properly or whatever. I would appreciate any assistance I can get :-) Thanks everyone. What code must I use if I want to create an order form on my website where patrons can order and/or request a product and/or services from the price list, the order form should calculate the total amount of the products/services requested, the VAT of 15% and add that to the order amount, Please help?
Hello, javascript seems to return the calculate the follwoing: (1 / 0.88) * 4.4 = 5.000000000000001 Excel evaluates the same sum to be 5 even to 20 decimal points. My calculator does the same. Having the 1 on the end throws off some of my calculations. Why is javascript evaluating like this?? Many thanks All, Below find my JS which is supposed to do the following: Take user supplied numerical values from 7 fields, perform the calculation function that's in the code and place it into the Total box / field. Needless to say ...or I wouldn't be here...it doesn't work. I thought maybe the problem was in the function, but I'm not sure Thanks to all who can help!

I have a javascript that should convert any date into a number between 1 and 260. Based on the outcome of that calculation, a viewer is directed to a specific web page. How can I verify the calculation? How can I see what number javascript is arriving at so I can backtrack to the error? It is not serving up the correct page. I have compared the results to a calculator on another website that uses a different script to calculate the same result -- that's why I am saying the end results are not correct. On the other website, scroll down to where you enter a date. It returns a name just above the date (example: July 25, 1970 returns Electric Star). The script I included above returns Yellow Sun. July 25, 1970 should = 68. Code: function calculate() {
if(!isValidDate())
return;
var result = 0;
var cuttingAge = 260;
var yearBox = document.getElementById("year");
var year = yearBox.value;
var month = document.getElementById("month").value;
var day = document.getElementById("day").value;
//Rule # 1
if(month==1 || month==2){
var selectedYearIndex;
for(var i=0; i<yearBox.options.length; i++){
if(yearBox.options[i].selected){
selectedYearIndex = i;
break;

Hi there! I hope someone can help me figure out the last little bit of this project. I'm building a form that is calulated based on the options selected with a javascript form. This is my first attempt at something like this so I'm a bit lost at the final update. First to be sure I'm on spot here is the javascript I'm using to update the form - Code: <script>
function BDWcalc ()
{
var listeners = document.getElementById('listeners').value;
var bitrate = document.getElementById('bitrate').value;
var hours = document.getElementById('hours').value;
var days = document.getElementById('days').value;
var total = document.getElementById('BDWTotal');
var sum = days*hours*3600*bitrate/8*listeners/1024/1024;
total.value = sum.toFixed(2)+" GB";
}
</script>
I'm calling the script in the header of the site with the following line of code Code: <script type="text/javascript" language="JavaScript" src='javascript/BDWcalc.js'></script> Now here is the form where I get stuck. It the last field which is to be updated when the option values are changed. For my purposes here, I've merely created a correct value as a default based on the items selected, but it is not actually being calculated by the script. I need the correct syntax there to get this all to work. Sure hope someone can help - Form Code: <table width="530" border="0" cellspacing="0" cellpadding="5">

The form can be view here Thank you in advance for any help offered. I've search and found things that are similiar, but none that are exactly what I need here. Ruth Hello, I am trying to make a page with a target heart rate calculator that displays the heart rate in a text box. This code displays on a new page instead of in the box even though I put an input box, plus it doesn't display the correct value. I think the problem is in the function itself: Code: <script>
function calcHeartRate()
{
var age = ""
var heartRate = 220 - age
var minRate = heartRate * .5
var maxRate = heartRate * .85
rate = document.write(heartRate)
document.myForm.yourRate.value = rate
}
At any rate, here is the form also: Code: <form name = "myForm"> Age:</br> <input type = "text" name = "age" /><br/><br/> <input type = "button" value = "Calculate Your Maximum Heart Rate:" onclick= "calcHeartRate()"/> <br/><br/> Max Heart Rate:<br/> <input type = "text" name = "yourRate" /><br/><br/> </form> I'm sure this is jacked up code since I have definitely been struggling. If you want me to post my entire code, I will, but it is my understanding that it is against the guidelines. Posting a working code is definitely not necessary. Please give me an idea as to what is wrong and I will go from there. I do not want the actual answer. I kind of think the problem is with my age variable but I am not sure what it is. Thanks! new to JavaScript, simple question... question: how do i determine an output from a prompt to be bold? e.g. a user enters "hello" and the output printed from the prompt becomes bold one=parseFloat(prompt('enter number',0.bold)); I'm working very hard to create a dynamic web-site for use in the education sector using server-side php/MySQL and client-side HTML with javascript. I have a logon page (index.php) which looks to see if the cookie 'mylogon' is set with the value 'Again'. This cookie is set when the PHP element on the server detects an invalid username/password combination. If so I have a javascript function (see below) call from the HTML <body onload="check_invalid_user()"> I know that the function Get_Cookie is working ok and that the javascript variable 'again' has the value 'Again' in it and has a length of 5. The alert function is not executed though. function check_invalid_user() { again = Get_Cookie('mylogon'); // document.write(again); // document.write(again.length); If (again == 'Again') { alert("User-id and/or password incorrect -- Please re-enter"); } } ============= Any help would be appreciated Many thanks in advance. (Yeah you guessed it I'm new and raw to this stuff. Pretty pretty please help me with this I am running out of time and pulling my hair out with this whole thing. Thanks a million in advance!

But I cant work out how to get rid of it. This is the html it is a transistional XHTML doc type.

//variableslide[x]=["path to image", "OPTIONAL link for image", "OPTIONAL text description (supports HTML tags)"]

I have taken out the credit, as I have changed it a bit, but will reinstate it later on. All I really need to know is how to define it in the XHTML maybe. Can anyone help? I tried to write the variable my_var into a text file but it only shows null after executing the code. Can anybody help pls?? Below is my code <html> <head> <script language="javascript"> var my_var function WriteToFile() { my_var = 123; document.write(<?php $file="file.txt"; $fh = fopen($file, 'w') or die("can't open file"); ?>; document.write(<?php $stringData = my_var ?>; document.write(<?php fwrite($fh, $stringData); ?>; document.write(<?php fclose($fh); ?>; } </script> </head> <body onLoad="WriteToFile();"> <p>Hello World</p> </body> </html> I am still learning javascript so forgive me if this question is a bad one, I am making scripts for Greasemonkey for a website I am a part of. One of the developers recently commented out (in the source code) a feature that was available before. It is a Football MMORPG game and it used to show college players 40 times but over the past month he commented out the tag that held the script function. I want to know if i can either A) write a js code that can remove the comment tag in the source code or B) write a code that will just add another tag under that and have that js function that was commented out valid. I tried something but ended up just having that function pasted onto the page instead of having it put into the source to have it read by the rest of the data.. here is what im talking about <TABLE width=800 cellspacing=0> <tr> <td colspan=3 style="FONT-SIZE: 11pt"> <b>Hometown:</b>Fort Hunt, VA<br> <b>Height:</b>6-0<br> <b>Weight:</b>206<br> <!--b>40 Time:</b><if rs("team_id")>0 or bRated then><=formatnumber(rs("forty"),2)><br><end if --> i just want to see if there was any way to just delete the comment out of it so i can get this feature again is all. Any help would be awesome... and sorry for the long post I have a page with options, and I need to hide options unless a certain choice is selected. So say you have a select box for male and female, if they select male, I need it to show male options, and if they select female, it shows female options. How can I hide things until selected and then show the textboxes and stuff? Thank you! Hi, At www.happydaysremovals.com.estimatenew.html. Users fill in a form which has items of furniture, so they enter a number next to each item of furniture. The HTML uses text fields. When the form is submitted, the form is submitted to a php script that emails the results to myself. I am trying to also have a javascript function which runs before the php script runs. This javascript works out the cubic footage of all the items. If a user put "3" in the sofa text field, and I have defined that a sofa is 45 cubic feet, then the javascript will multiply 3 * 45. It will do a similar thing for all items of furniture, then add them all up to give a total cubic feet. I want that total field to then sent as a variable to the php script, along with all the other variables. My code so far (which doesnt work) Code: <script language="JavaScript">
function calculate()
{
var sofa_3_seater = document.getElementById('sofa_3_seater').value*45;
var sofa_2_seater = document.getElementByID('sofa_2_seater').value*30;
var armchair_large = document.getElementByID('armchair_large').value*15;
var total=sofa_3_seater+sofa_2_seater+armchair_large;
document.getElementByID('total').value = total;
}
</script>
I have used a hidden field for the total value: Code: <input type="hidden" name="total" value=""> I want the javascript result to change the value of the hidden field that is called total. THen I want it all to be posted to the PHP script and email everything to me, including this newly calculated total field! THanks I have a vendor delivered java script code that I am currently customizing. The original code involves a user when selects a "check box" option value , a small function is called titled "VerifyAcctType". Currently when a user selects the check box some values are defaulted into the form. Now to this function code below i have to add logic when user selects the same check box option FIRST a small pop up window should appear which lists two radio buttons"I Agree to terms" and "I do not agree to terms" options , user need to select one of the options in the pop up to proceed. If the user agrees to terms then the control should go back to the "VerifyAcctType" function and proceed with remaining steps like before else if the user selects "I do not agree" the logic should not proceed further in "VerifyAcctType" function. Here is the current code tied to VerifyAcctType function ============================================== function VerifyAcctType(win,type) { var AcctType var ThisWindow var ThisForm if (win == "ADD") { ThisWindow = AddAccountWind ThisForm = AddAccountWind.document.addform } else if (win == "CHG") { ThisWindow = ChangeAccountWind ThisForm = ChangeAccountWind.document.chgform } if (type == "P") { <<I NEED NEW CODE HERE FOR THE POPUP>> Maccttype = type ThisForm.description.value = "My Company" ThisForm.comp_id.value = "1234567" ThisForm.comp_id.disabled = true } else { Maccttype = type ThisForm.description.value = "" ThisForm.comp_id.value = "" ThisForm.comp_id.disabled = false } } I am a java script beginner , any help is appreciated. Hello everyone, i desperatly need a script for my website but am totally stuck, I hope someone can help On my website i want a search box. I want it so that if a use types in one of my predetermined search terms then they would be sent to a predeterimed page in my own website. For example: I have a group of 5 keywords - nokia, mobile, vodafone, cellphone, iphone. If a user types any of those keywords into my search box then xxxxx.com/mobilephones.htm will be loaded up I have another set of 5 keywords - cat, dog, rabbit, mouse, snake. If a user types any of those into the search box then they are directed to xxxxx.com/animals.htm and so on ... So as you can see, its not a 'normal' search engine I will be creating new pages and will need to add the chosen keywords for it as time goes on etc Nearly everywhere i look for something to help me all I can find are standard search engine scripts which are no good as they display search results instead of directing to specific urls depending on the keywords entered I would also need to 'capture' what search terms are being entered so that I can build some user statistics I understand html and javacript to an intermediate level Can anyone help / provide a script that I could use? Although Im a student Im willing to pay some funds to anyone that can do this for me Many thanks Terry |
