JavaScript - Javascript Calculator Not Working On Firefox Or Flock
I am having trouble with my calculator not working in Firefox or Flock when it does in IE.
I have installed Firebug but my having trouble understanding that - I have not used Mac's, so am not getting anywhere. The web page is http://scubaservice.com.au/Dive-Equi...Insurance.html, the premium calculator is supposed to return 4 values as you enter the equipment value or change the state. Code: function premium_calculator()
{
var val = document.getElementById('user_input').value;
var state = document.getElementById('user_state').value;
var excess=[0.03,0.0285714285714286,0.0257142857142857,0.019047619047619]; // excess rates
var gst=.10; // GST rate
var margin=.60; // margin
// state array
// var States=["QLD","NSW","ACT","VIC","TAS","SA ","WA ","NT "];
var sd=[0.075,0.09,0.1,0.1,0.08,0.11,0.1,0.1]; // stamp duty rates
if (val<100000)
{
switch (state) {
case "QLD":
var n1 = val * excess[0];
if (n1 < 75)
n1 = 75;
var gn1 = n1 * gst;
var sd1 = (n1 + gn1) * sd[0];
var m1 = n1 * margin;
var mx1 = (val/2500)*((12/36)*25);
var gm1 = (m1 + mx1) * gst;
var r1 = roundNumber((n1+gn1+sd1+m1+mx1+gm1),2);
var n2 = val * excess[1];
if (n2 < 75)
n2 = 75;
var gn2 = n2 * gst;
var sd2 = (n2 + gn2) * sd[0];
var m2 = n2 * margin;
var mx2 = (val/2500)*((12/36)*25);
var gm2 = (m2 + mx2) * gst;
var r2 = roundNumber((n2+gn2+sd2+m2 +mx2+gm2),2);
var n3 = val * excess[2];
if (n3 < 75)
n3 = 75;
var gn3 = n3 * gst;
var sd3 = (n3 + gn3) * sd[0];
var m3 = n3 * margin;
var mx3 = (val/2500)*((12/36)*25);
var gm3 = (m3 + mx3) * gst;
var r3 = roundNumber((n3+gn3+sd3+m3+mx3+gm3),2);
var n4 = val * excess[3];
if (n4 < 75)
n4 = 75;
var gn4 = n4 * gst;
var sd4 = (n4 + gn4) * sd[0];
var m4 = n4 * margin;
var mx4 = (val/2500)*((12/36)*25);
var gm4 = (m4 + mx4) * gst;
var r4 = roundNumber((n4+gn4+sd4+m4+mx4+gm4),2);
break;
//this case is repeated for each state with slight differences
}
}
else
{
alert ("Please contact us for quote");
r1 = 0;
r2 = 0;
r3 = 0;
r4 = 0;
}
document.getElementById('val_100_1').innerHTML = r1;
document.getElementById('val_250_1').innerHTML = r2;
document.getElementById('val_500_1').innerHTML = r3;
document.getElementById('val_1000_1').innerHTML = r4;
}
function roundNumber(rnum, rlength) { // Arguments: number to round, number of decimal places
var newnumber = Math.round(rnum*Math.pow(10,rlength))/Math.pow(10,rlength);
return newnumber.toFixed(2); // Output the result to the form field (change for your purposes)
}

I have used the code of my affiliate software to show my company logo. This code works in Firefox, but for some reason doesn't work in IE. The company who own the affiliate software have never seen this problem before and have been unable to assist. Not sure if it's a server problem? To see the problem have a look at logo at the top of my test website in firefox then IE. http://www.nctshop.co.uk/staging/ Here is a snippet of the code below.

Hi There, I have recently completed making a website for my sister's wedding. I am quite new to the web design world, and have only taken 2 classes on the subject. I used a Javascript function that was provided to us in one of my HTML coding classes in order to automatically resize the (nesting?) div's according to how long the content in them is. This all seems to work perfectly fine in Google Chrome, as well as most versions of Internet Explorer - however, in some versions of internet explorer, and ALL versions of Firefox, this resize function does not seem to work. Since this coding was provided to me by a teacher (who is unfortunately in another country), I'm not sure what kinda of edit would make it so it would function in Firefox, or if there is a way to make in function in Firefox at all. I would appreciate if some of you could take a look at it, and let me know if you have any ideas/suggestions/advice, as to what is happening with the code/why it does not work in Firefox/some versions of Internet Explorer. The specific javascript code (which i assume is the issue here - please let me know if I'm wrong about it being the javascript that isn't working) is he PHP Code: function fnReset(){ document.getElementById('dTorso').style.height="380px"; document.getElementById('dMiddle').style.height="auto"; var middleHt=document.getElementById('dMiddle').scrollHeight; var maxHt=Math.max(380,middleHt); document.getElementById('dTorso').style.height=maxHt + "px"; document.getElementById('dMiddle').style.height=maxHt + "px"; } Which is then called to action he Code: <body onLoad="fnReset();> Also, in some versions of Firefox, the background image for the whole page isn't showing up either - any tips on why that is happening would also be amazing. Thank you so much for any help you may provide. This is a gift to my sister and her fiance, and I really want it to work well for them, and all their guests. Thanks! Hi, I am having a strange problem. I have a javascript that I am running on my system and on server(both in IE and FF). The problems I am encountering are as follows: My system IE - everything working fine FF - Not able to set focus correctly. When focus() is called, it jumps to next field. On Server IE - Focus doesnt set as expected. No blinking cursor.Doesnt do anything. FF- Same thing as above. When focus functionality is called, nothing happens. It is a long javascript, but here is a snapshot of the code with problem. Please let me know if you want to know about any variables. The (fname,lname..)are all the Name attributes of textbox. userArray is a array containg the number of users whose information is not filled up correctly(ie. some reqd fields are left empty). Code: df=document.form;
for(var j=0;j< val;j++)
{
if(df['fname'+userArray[j]].value =="")
{
df['fname'+userArray[j]].focus();
break;
}
else if(df['lname'+userArray[j]].value =="")
{
df['lname'+userArray[j]].focus();break;
}
else if(df['ph'+userArray[j]].value =="")
{
df['ph'+userArray[j]].focus();break;
}
else if(df['email'+userArray[j]].value =="")
{
df['email'+userArray[j]].focus();break;
}
else if(df['comp'+userArray[j]].value =="")
{
df['comp'+userArray[j]].focus();break;
}
else if(df['addra'+userArray[j]].value =="")
{
df['addra'+userArray[j]].focus();break;
}
else if(df['city'+userArray[j]].value =="")
{
df['city'+userArray[j]].focus();break;
}
else if(df['state'+userArray[j]].value =="")
{
df['state'+userArray[j]].focus();break;
}
else if(df['zip'+userArray[j]].value =="")
{
df['zip'+userArray[j]].focus();break;
}
else if(df['country'+userArray[j]].value =="")
{
df['country'+userArray[j]].focus();break;
}
}
The code is definitely not clean,pls forgive me for that. Any suggestion on that will be appreciated. Thanks Hey everyone. I have built a simple page for where I work, nothing complex going on here at all. But for some reason it won't run the Javascript functions in Firefox. Sarfari and Chrome work fine. It's not calling any external files or anything, like I said super simple. So if anyone can go to the page, view the source, take a look and let me know what I am missing here I would be greatly appreciative. http://www.aaronhager.com/BM/ To see what it does, just open that link in Chrome or Safari. I am more of a Flash guy then Javascript, and hopefully the reason is simple for one of you geniuses out there. Thanks A. Hey guys, My code works perfectly fine in internet explorer and google chrome, however, in firefox it does not. I have created an online form, but nothing happens when pressing the "submit" button firefox, whereas in other browsers, it works correctly. Also, the centering of the form is different. Please help me if possible.

Hi All, This is my first post in this forum. I am relatively new to javascript. Hope I get some guidance here. Also I would like to contribute here when I get little expertise on javascript. I have developed following snippet of code, which is working very well with firefox 6.0. But when it comes to IE 8.0, it just does not work. Quote: <SCRIPT LANGUAGE="JavaScript"> function refreshFrame() { frames['top'].window.location.href = "report.php?parent_id=<? echo $parent_id; ?>"; } </script> </head> <? include('style.php'); include('PHP_functions.php'); print(" <FRAMESET rows='96,100' onLoad=refreshFrame() BORDERCOLOR=blue BORDER=0> <FRAME SRC=blank.html SCROLLING=NO NORESIZE NAME=top> <FRAME SRC=manage.php?view=show_all&parent_id=$parent_id NAME=bottom> </FRAMESET> "); ?> </HTML> In the above script, I am trying to load the frame top after loading frame bottom, as the latter takes more time to load due to some processing involved. Till frame bottom is under processing stage, I display a message "Processing Please wait" which is coming from blank.html. Working under Firefox: It loads blank.html first and displays the message as "processing please wait". Once frame bottom has completed the processing it displays its contents at second half of the webpage. Then finally frame top gets loaded on first half of the web page. This is the expected result. Here URL does not change as the URL remains same as before "http://xyz.com/index.html" Not Working under IE It loads blank.html first and displays the message as "processing please wait". Once frame bottom has completed the processing it displays its contents at second half of the webpage. Then finally frame top gets loaded on whole page instead of first half of the page. Here URL changes to complete new URL as "http://xyz.com/report.php?parent_id" Can anyone please suggest what could be reason for this. Thanks, Vinay I am working on an Mpg calculator and I am stuck any input would be greatly appreciated. Code:

I have a mistake when it is suppose to calculate. Thanks to all It works in Google Chrome but not Firefox and Internet Explorer. My computer has blocked Opera and I don't know how to change that. Too much energy to investigate now, I'll do so later. Are there any pros that can tell me why this is happening? I'm assuming GoogleChrome is fixing a syntax error that FF and IE don't. Code: var request;
request=false;
try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = false;
}
}
}
function isAlNum(str){
return /^[a-z0-9]+$/i.test(str);
}
var preUsername;
var same;
function updatePage() {
if (username.value.length>0){
if ( request.responseText.indexOf("0") == -1 )
{userNameErrorBox.innerHTML=username.value + " has already been taken";
usernameSuccessBox.innerHTML="";}
else
{userNameErrorBox.innerHTML="";
usernameSuccessBox.innerHTML=username.value + " is available";}}
}
function nameTest()
{
if (username.value==preUsername)
{same=1;}
else
{same=0;}
if (!isAlNum(username.value))
{if (username.value.length>0)
{username.value=preUsername;}}
else
{preUsername=username.value;}
if (username.value.length>0 && username.focus && same===0)
{
userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";
request.abort();
var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
}
if (username.value.length===0)
{ userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";preUsername=""; }
}
I back tracked what i did and it appears that this code Code: var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
has the problem. When I set up alerts to see what works and what doesn't, this code seems to be causing the FF and IE to not work, but I can't tell what it is that's causing them to fail. This is javascript that is suppose to check if a name has been taken by another user. I'm working on a fairly large project that I wish to be the new formspring, (size wise) I procrastinated for 2 weeks of my 12 week break and now that I'm just getting started on it I'm running into an ishness load of problems... Very de-motivating I have an online calculator in javascript which works in IE but not Moz. Can anyone help: site: http://www.exigotranslations.com code: function workit() { var xsource = new Array(0,0.09,0.1); // source language var xtarget = new Array(0,0.09,0.10,0.12,0.14); // target language var xtype = new Array(0,0,0.06,0.02,0.06,0.04,0.06,0.03,0.01); // type of text var itemA = parseInt(form1.words.value); if(!itemA){itemA=1}; var itemB = parseInt(form1.source.options[form1.source.selectedIndex].value); var itemC = parseInt(form1.target.options[form1.target.selectedIndex].value); var itemD = parseInt(form1.type.options[form1.type.selectedIndex].value); var total = (itemA*(xtarget[itemC]+xtype[itemD])); if(total < 9) {total = 9}; mytotal.innerHTML = total.toFixed(2); } link to code from webpage is: <script src="Javascript/formcheck.js" type="text/javascript"></script> Can anyone help with what I have done wrong. Thanks, Richard Hello I have been asked by a friend to put together a BMI calculator. I know there are javascript ones already out there that I could use the code for, but a) it needs to do a specific thing b) I am interested in learning a bit of jscript - hence why I just spent about 4hrs trying to get it working You can see what I have been working on here http://www.kubedp.co.uk/bmi2.html Basically - what it needs to do is the following :- - User can either enter Feet/Inches or centimeters for height - User can either enter Stones/Pounds or Kilos for weight. - If they enter Feeet/Inches and centimeters - it throws an error (similar thing for weight). It then outputs the BMI to txtBMIResults. I managed to get the validation working on not having both Stones/Pounds and Kilos filled in etc, but when it comes to the actual calculation - I am stumped. If someone could look at this for me and hopefully code it and comment it so I can understand what has been done to get it working so I might learn, that would be fantastic. http://www.bmi-calculator.net/bmi-formula.php Is the formulas for calculating BMI. Not sure if you can tell from the code - but I was trying to get it so that the calculation was always done on Kilos and Meters, so I was taking the Stones and Pounds and feet and inches and trying to convert it to kilos and metres and then run the calculation. Hope I have been clear. Many thanks for any help anyone can offer I'm not sure what the code is to add this to javascript. I don't know if anyone can help me with this? Each numeric button should change the input box up at the top to whatever. When one of the operator buttons (+,-,*,/) is pressed, the value in the input box at the top should change to 0. Before an operator button is pressed, the value should be stored in a variable to keep track of the left-hand side of the equation. After it is pressed, the value should be stored in the right hand side variable. Thanks Hi all master and expert coders I am working on a calculator which using the instructor's codes from the school. The problem that I having right now is the operator. I have successfully complete only the addition, but could not manage on subtraction and the rest operator. I hope experienced codes would help me out on this. Below is my codes. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <script type="text/javascript"> function calculate() { var value1 = parseInt(validate(document.getElementById("value1").value)); var value2 = parseInt(validate(document.getElementById("value2").value)); radioButtonCheck(); checkboxCheck(); dropDownListCheck(); document.getElementById("result").value = addition(value1, value2); document.getElementById("result").value = subtraction(value1, value2); document.getElementById("result").value = multiplication(value1, value2); document.getElementById("result").value = division(value1, value2); } function validate(value) { if (value == null || value == "") { alert("Required Field"); return 0; } else if (isNaN(value)) { alert("Must be a number"); return 0; } else return value; } function addition(value1, value2){ return value1 + value2; } // trying to use the same addition return statement but fail. function radioButtonCheck() { if ((document.getElementById("radio1").checked == false) && (document.getElemtById("radio2").checked == false)) { alert("Please select a radio button"); valid = false; } } function checkboxCheck() { if ((document.getElementById("cbox1").checked == false) && (document.getElementById("cbox2").checked == false)) { alert("Please select a checkbox"); valid = false; } } function dropDownListCheck() { if ((document.getElementById("ddlOperator").selectedIndex == 0)) { alert("Please select a operator"); valid = false; } } </script> <title>Calculator By Alsus</title> </head> <body> <h2>Calculator</h2> <table border = "1"> <tr> <td>Value 1:</td> <td><input type="text" id="value1" name="value1" /></td> </tr> <tr> <td>Value 2:</td> <td><input type="text" id="value2" name="value2" /></td> </tr> <tr> <td>Operator:</td> <td><input type="text" id="Operator" name="Operator" /></td> </tr> <tr> <td><input type="radio" id="radio1" name="radio1" value="radio1" />Radio1<br /></td> <td><input type="radio" id="radio2" name="radio2" value="radio2" />Radio2<br /></td> </tr> <tr> <td><input type="checkbox" id="cbox1" name="cbox1" value="cbox1" />Checkbox 1<br /></td> <td><input type="checkbox" id="cbox2" name="cbox2" value="cbox2" />Checkbox 2<br /></td> </tr> <tr> <td> <select id="ddlSelect"> <option value="+">+</option> <option value="-">-</option> <option value="*">*</option> <option value="/">/</option> </select> </td> <td> </td> </tr> <tr> <td>Result:</td> <td><input type="text" id="result" name="result" /></td> </tr> </table> <input type="submit" id="btn_sub" name="btn_sub" value="Submit" onclick="calculate()" /> <input type="reset" id="btn_res" name="btn_res" value="Reset" /> </body> </html> aaaaaa
I need help trying to figure out how to get my bmi calculator to work. I cant figure out what is wrong with my formula part and why it wont calculate the numbers you type in...pls help! <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <script type="text/javascript"> function calculateBMI() { var weight = numb(document.data.weight.value) var height = numb(document.data.height.value) var height2 = height2 * height2 var BMI = weight * 703 / (height2 * height2) document.form.BodyMassIndex.value=custRound(BMI,1); } </script> <title></title> <style type="text/css"> div.c2 {text-align: center} input.c1 {font-size: 8pt} </style> </head> <body> <div class="c2"> <form name="form" id="form"><input type="text" name="weight" size="4"> Weight (in Kilos) <input type="text" name="height" size="4"> Height (in Centimeters)<br> <br> <input type="text" name="BodyMassIndex" id="BodyMassIndex" size="4"> BMI <input type="button" class="c1" value="Calculate" onclick="calculateBMI()" name="button"> <input type="reset" class="c1" value="Clear Form"></form> </div> </body> </html> This is what I have so far, but now I am stuck. My instructor wants the output value (Number Set C) to include Number Set A and Number Set B. For instance, if Number Set A is "10" and you want to add Number Set B whose value is also "10", my instructor wants Number Set C to say "10 + 10 = 20". Where am I going wrong, and what is the easiest way I can make this work while making as little changes as possible? Most of the code is what my instructor requires us to use. Code: <HTML>

Hello everyone, wondering if I could get some help. I have not done anything with html and javascript until this afternoon and funnily enough I'm struggling a tad I am creating a free website about the dangers of chocolate for dogs. Basically I need a calculator to calculate the toxic amount for the user input of their dogs weight in kgs. I figured doing one for each type of chocolate would be easier than doing something where a box was ticked for each type of chocolate so have been trying to do one for milk chocolate first. This is my feeble attempt, it looks good but doesnt work, my javascript is clearly majorly wrong somewhere! <html> <head> <script language="JavaScript"> function calc(form) { var f = parseFloat(form.kg.value); var T = 0; T = (f/0.45)*28.35; form.answer.value = T; } // done hiding from old browsers --> </script> </head> <body> <FORM> <h2>Toxic dose of milk chocolate</h2> Enter dogs weight in kg: <INPUT NAME="kg" VALUE="0" MAXLENGTH="100" SIZE=25> <p> Click to calculate toxic dose in grammes: <INPUT NAME="calc" VALUE="Calculate" TYPE=BUTTON onClick=kg(this.form)> <p> Toxic amount of milk chocolate is: <INPUT NAME="g" READONLY SIZE=25> </FORM> </body> </html> Can anybody help? Thanks in advance. I need help putting parentheses in my calculator. Could anyone provide me some source code for parentheses in a calculator? If not source code, could you offer me recommendations as to how to solve my problem? Thanks! I've seen several Java or Perl Derivative Calculators online, but I can't seem to find any in JavaScript. Has anyone tried? I might need one in JavaScript (or Flash ActionScript) for a graphing tool I'm working on, and I don't want to reinvent the wheel if I can avoid it.
