JavaScript - Javascript Weight Converter Help?
Hello all. I'm so glad i found this forum!!! This looks like a great coding community. This will be my First Post.
I was wondering if you guys can help me with my weight converter. I cant seem to make it work properly on my site. here is the code im using: <p class="about">Convert weight measurements between U.S./Imperial and SI (Metric) units<br /> Type your value in a box, click the <input onclick="alert('Not this button!')" type="button" name="test_bt" value="Go!" /> and all unit conversions in the same category will be calculated.</p> <form action=""> <table

Similar TutorialsHello, I am having trouble with a javascript length converter that I got from http://www.javascriptkit.com/script/...onverter.shtml It is working fine in dreamweaver, but when it goes live on my site, the calculations do nothing. I can see everything in the drop down menus, but when i click the "to" button, nothing happens. I got the following errors from chrome when activating any of the calculation functions. I'm wondering if anyone here can help me decipher these 1. Uncaught TypeError: Cannot read property 'from_unit' of undefined 1. convert_unitDefault.aspx:459 2. (anonymous function)Default.aspx:482 3. onchangeDefault.aspx:483 1. Default.aspx:459Uncaught TypeError: Cannot read property 'from_unit' of undefined 1. convert_unitDefault.aspx:459 2.

(anonymous function)Default.aspx:516 3. onclickDefault.aspx:517 I imagine this would be very simple for someone who knows javascript. I want to have three fields. First field is "posted speed limit", second field is "actual speed" and third field will be the output field. All the script needs to do it subtract the posted speed from the actual speed and add a ZERO to the end; which is the amount of the speeding ticket. The minimum fine is $100, however. So, 5 miles over the speed limit would be $100 (minimum value) 15 miles over the speed limit would be $150 (add a zero) 35 miles over the speed limit would be $350. etc. I know very little Javascript, if anyone could help me out with this, I'd appreciate it.

Hello, I've been reading my JS book, have done a 'Degrees Converter' which converts fahrenheit into centigrade. There is a prompt box which automatically loads when the website is loaded. I am pressuming this is because I have my script in the body. I have a question if anybody could possibly help me out. How do I get my script as a link? To explain a little better, I wanted to put the words 'Degrees Converter' onto my page(as a link), so that when people click the link, it loads up the prompt box. I'm very new to JavaScript, so if anyone could help me out it would be a great help. Thank you very much.

This code requires someone to change the figure in the javascript as well as the html. I guess I need to somehow automatically pick up the numeric characters only from the html which appear on the same line of code... or perhaps there's an easier way.? Any help would be much appreciated. Thanks Hey guys. I am in an introductory computer science class and I am having trouble writing JavaScript code for a currency converter. I can get it to where it spits out numbers, but its always the same numbers. I think there's something wrong in the calculations part of my code but I can't figure it out. I am posting it below, and any help would be greatly appreciated. Thank you. <html> <head> <title>CURRENCY CONVERTER</title> <script language="JavaScript"> function converting() { with (document.conversions) { if (unit[1].selected) { var result = eval(unit.value*0.974); convertedValue.value = result; } // end if if (unit[2].selected) { var result = eval(unit[2].value*0.492); convertedValue.value = result; } // end if if (unit[3].selected) { var result = eval(unit[3].value*0.706); convertedValue.value = result; } // end if } // end with } // end function converting </script> </head> <form name = "conversions"> <table border=6 bgcolor ="yellow"> <tr> <td><font color="red" size=6>Enter amount in U.S. $:</font></td> <td><input type="text" name="inUnit" size = 4></td> </tr> <tr> <td><font color="red" size=6>Select target unit:</font> <td><select name="unit"> <option value="Select Currency" selected>Choose one... <option value="1">Canadian Dollars <option value="2">British Pounds <option value="3">Euros </select> <td><input type="button" value="Convert" onclick="converting()"> </tr> <tr> <td><font color="green" size=6>Converted Value:</font> <td><input type="text" name="convertedValue" size = 4> <td><input type="reset" value="Reset"> </tr> </table> </form> </body> </html> Hi all -- I realize this is probably pretty simple, but it's been a while since I did any Javascripting, and things have changed a great deal. My apologies if I sound a bit clueless. I need to create a conversion tool. On one side of the tool are 4 form boxes. On the other, just text (not in form boxes). Under the covers, I have formulas for converting the numbers -- mostly basic math functions. So, the user types in numbers, clicks convert and the text changes. For some reason, I'm having a hard time getting this to go. How can I get the results of these calculations to show up as text within a DIV tag and not inside a form element? There are lots of examples of getting these calculations to appear within form boxes, but not within DIVs. Any examples would be greatly appreciated. This page is already using the Dojo toolkit for some other functionality, is this something I could leverage here to build my Javascript? Thanks in advance for your patience. I am trying to make a unit converter with two dropdown boxes, two textfields and a button. I want to enter a number into the first textfield, select a unit option, then select another appropriate unit option based on the first selection, press the button and get the result in the second textfield. What would be the best approach for this. So far I have: <html> <head> <script type="text/javascript"> function convertUnit () { // convert pound to kilogram document.unitForm.toField.value = document.unitForm.fromField.value / 2.2; // convert kilogram to pound document.unitForm.toField.value = document.unitForm.fromField.value * 2.2; // convert inch to centimeter document.unitForm.toField.value = document.unitForm.fromField.value / 2.54; // convert centimeter to inch document.unitForm.toField.value = document.unitForm.fromField.value * 2.54; } </script> </head> <body style="background-color:lightgray"> <form action="" name="unitForm"> <input type="text" name="fromField" onfocus="this.form.fromField.value=''; style.background='lightyellow';" onblur="style.background='white';" /> <select name="fromList" > <option value="" selected="selected">Unit</option> <option id="fromPound" value="2.2">lb</option> <option id="fromKilogram" value="1.0">kg</option> <option id="fromInch" value="1.0">in</option> <option id="fromCentimeter" value="2.54">cm</option> </select> <input type="button" value="Convert" onclick="convertUnit()" /> <input type="text" name="toField" readonly="readonly" /> <select name="toList"> <option value="" selected="selected">Unit</option> <option name="toKilogram" id="toKilogram" value="1.0">kg</option> <option name="toPound" id="toPound" value="2.2">lb</option> <option name="toCentimeter" id="toCentimeter" value="2.54">cm</option> <option name="toInch" id="toInch" value="1.0">in</option> </select> <input type="reset" value="Reset" /> </form> </body> </html> Hi, I need to create a currency converter using a drop down menu. Firstly i needed to do a regular expressions check to make sure only numerics are entered and I got that. The one thing im pretty confused on is how to do the calculations in the actual function. Ive popped the code below, and if anyone could give me some hints on how to get the data from the drop down menu and calculate it properly that would be awesome. Thanks. -oh and i know all my coding is here but i think its relevent that you can view it all. Code: <html>

I can only seem to find really complicated ones online, nothing simple which i think this is. Thanks Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version.

$('#button-cart').bind('click', function() {
$.ajax({
url: 'index.php?route=checkout/cart/update',
type: 'post',
data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'),
dataType: 'json',
success: function(json) {
$('.success, .warning, .attention, information, .error').remove();
if (json['error']) {
if (json['error']['warning']) {
$('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.warning').fadeIn('slow');
}
for (i in json['error']) {
$('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>');
}
}
if (json['success']) {
$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.success').fadeIn('slow');
$('#cart_total').html(json['total']);
$('html, body').animate({ scrollTop: 0 }, 'slow');
}
}
});
});
//--></script>
And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can...
