Library For Unit Conversion?
Apr 20, 2007Is there a free js library for doing unit conversions? I am putting
together an app that needs to convert volume and weight, among
others. You'd think that one exists, but I have yet to find it.

I am using GreaseMonkey to load jQuery 1.3.2 (there is a bug with the latest version of jquery and GM) and jQuery UI 1.8.0.I am using jQuery via GM to manipulate the GUI of a content management system. This CMS uses its own JS library to dynamically add stuff to the dom.
Question:How can I target a dom element that was added to the dom via this other JS lib?In other words, the CMS will add a div to the dom, and I am not sure how to tell jquery to wait for these elements to "be there" before applying the jquery goodness. Specifically, I would like to do this:
$(function() {
$('#zen1227').resizable();
});
But "#zen1227" does not "appear" until later via this other JS library.
Here is a unit converter. At the moment it does length and weight, both in imperial and metric measurements. I'll put up soon instructions on how to add more units/unit types.
View 3 Replies View RelatedI 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. This page is already using the Dojo toolkit for some other functionality, is this something I could leverage here to build my Javascript?

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:

May it be it takes only the very first digit into account? How to handle this without a core hack?
I have a string that I'm properly URL-encoding to be passed in a URL.
Here's the tag from the HTML source:
<A HREF="javascript:openPopWin('takeit.php?568&10&dr.+hobo%27s+scalpel',
325, 325, 'scrollbars')">
But when I mouse-over the link, the %27 shows in the status bar as a ' and
when I click on it, I get a JS error because of the extraneous '. The +s
are not being decoded - why is this one character, and is there a way to
prevent it?
I have a string that is encoded simply by replacing the letter with the
next letter in the alphabeta. I need a function to convert it back.
Following is the function:
function cnvtBack(encoded)
{
var orig = "";
for (i=0; i < encoded.length; i++)
{
var letter = "";
letter = encoded.charAt(i);
if (letter > 'a' && letter <= 'z')
letter = <<previous letter in alphabeta >> // HOW?
orig += letter;
}
}

It's not even covered in the book we're using for a text book. So I'm having some problems with it (big surprise right?) My assignment: Write a Java Script that will print out the Temperature in Celcius from 0 to 35, AND the corrosponding temperature in Fahrenheit. So basically it would generate the following:
0 Degrees in Celcius is Equivalent to 5 Degrees Fahrenheit
1 Degrees in Celcius is Equivalent to 6.125 Degrees Fahrenheit
2 Degrees in Celcius is Equivalent to 7.25 Degrees Fahrenheit
3 Degrees in Celcius is Equivalent to 8.375 Degrees Fahrenheit and all the way down to 35 degrees.

I have such problem when I post my object from client to server (php).
The object should be like so:
Code:
I converti it:
Code:
And send it though jquery and ajax:
property val is the object...
Then on side of server I gota string $_POST["val"]:
Code:
I try to convert it:
Code:
Value entered in textarea is: "this "TEST" is not going well"
JS sends to server this value: "this "TEST" is not going well"
How to force JS not to convert the string ? I want JS to send exactly what

I ran into this issue yesterday, and no matter what I try I can't seem to get it work correctly.
I need to parse out single quotes from a field, and replace them with double quotes, so it doesn't blow up later, like it did yesterday.
I've tried using regex, but I'm sure its not the correct syntax.
javascript Code:
document.all.SalesOrderForm.ShipNote1.value = document.all.SalesOrderForm.ShipNote1.value.replace(/'/g,""");
document.all.SalesOrderForm.ShipNote1.value = document.all.SalesOrderForm.ShipNote1.value.replace(/'/g,""");
Im need to create a conversion-script for a company that do step-competitions. You should be able to input a time-variable, choose what activity you did from a drop-down meny, click convert ("omvandla" in swedish") and the script prints what that is equal to in steps. I found a code online that does other conversion so i just redid that code to fit my demands. Everything looks alright in the browser, but the script doesnt print anything when i click "omvandla". Forgive me for posting the entire code, which is pretty long. But most of the code is just repetition, cause you have 58 types of activities to choose from.
Some words are in swedish, but the only two i think you need to understand is:
let me know how to convert a string to double in Jquery. String is an amount field like (3,154) which needs to be converted to Double.
View 1 Replies View Relatedi've found out how to find the distance between 2 lat lng points using google's distanceFrom method:
Code:
// NR14 7PZ
var loc1 = new GLatLng(52.5773139, 1.3712427);
// NR32 1TB
var loc2 = new GLatLng(52.4788314, 1.7577444);
alert(loc2.distanceFrom(loc1) / 1000);
However, I'd like to be able to convert a distance to lat lng. The main reason I'm doing this is so that I can figure out the bounds of a certain area of a co-ordinate. For example I specify a point, and then I need to draw a box around this area going x distance North, South, East and West, but until I know how many units make up a kilometre this wont be easy.
I guess I could go to google maps, click on a point and then click on another point and keep doing that until I get exactly 1km away from the original point, then just minus or plus for the lat and lng to find out the unit value for 1km, but I have a feeling that this wont be accurate. Can anyone lend any advice, I realize that what I'm asking is more a map question than a google maps javascript api question, but perhaps someone has come across this before?
Can someone help me with the converting the values to string by using the 'toString'. in java script.

View 3 Replies View RelatedI'm currently constructing a javascript "terminal" on a site I'm building so that I can test objects and functions outside of the web developer terminal in google chrome.
Given that I have active javascript defining an object called item, typing item in the chrome terminal returns Object and goes on to list the properties of item.
Moreover, I can define a function in the terminal like this: function(x) { return x }, and then function(item) will return Object and list the properties. However, if I use form data and user input in the place of the argument, the datatype becomes a string and not an object, so typing item in the form and clicking a button that performs function(document.form.text.value) returns the string item and not Object.
Is there any way to convert this primitive string to an object so that I can then iterate through properties, and so on?

View 5 Replies View RelatedI have used a Javascript function for temperature conversion(attached with an external js file). When the temp is converted we are supposed to get a message box if the temps fall under a certain amount.
Example: <90 degrees celcius : a message is supposed pop up.
I haven't been able to code the message box correctly for it to work.
How can I avoid type-conversion (object variable --> string) when
passing an object variable to a function?
Example:
-->
catch(myerrorobject)
alert(myerrorobject.filename);
{
my_function('bla: ',myerrorobject);
}
<---
I get the "myerrorobject.filename" in the alert-Box, but I get an
"undefined"-error, if I try to access myerrorobject.filename (or other
properties) in the function "my_function". Why?
