View 16 RepliesI am trying to convert binary to decimal with this function but it doesn't convert to decimal, but does decimal to binary.
Code:
function bin2dec() {
var x = document.getElementById("bin").value;
if ((/[^0-1]/g.test(x)) || x == "") {
alert ("You must enter an integer binary number!");
document.getElementById("bin").value = "";
document.getElementById("bin").focus();
return false;
}
x = parseInt(x);
var dec = x.toString(10);
var hex = x.toString(16).toUpperCase();
var octal = x.toString(8);
var figs = "The decimal representation of " + x + " is " + dec + "<br>";
figs = figs + "The hexadecimal representation of " + x + " is " + hex + "<br>";
figs = figs + "The octal representation of " + x + " is " + octal + "<br>";
document.getElementById("result").innerHTML = figs;
}
I need a Javascript that can process two math formulas to convert Estimated Average Glucose to HbA1c and vice versa. The formulas are as follows:
(28.7 x A1C) - 46.7 = eAG
(46.7 + eAG) / 28.7 = A1c
It could be a two function javascript or two separate javascripts, I am not that particular as long as it does what I need it to do. The way I would like to see it work is you type the number you have into a field, and press a button to convert it. If it was a two function javascript you would have to select the conversion type you want do first.
I am writing a program that will take user input and convert the 8 digits the user enters (the 0's and 1's) and converts them into an integer between 0 and 255. It is a very simple program but I am still having some errors :
import javax.swing.*;
public class BinaryToInteger
{
static String userInput = JOptionPane.showInputDialog("Enter a binary number with 8 integers to convert.");//Dialog Box that asks for user input
static int binaryValue = Integer.parseInt(userInput);//Parses the user's input into an integer

I am having an issue with converting my decimal to a percentage. Below is my code:
(cost * .06) is where the issue is
var cost = prompt("What is the cost of your purchase?", "")
document.write("Return Value: "+cost,("<br />"));
var salestax = cost * .06
document.write("Return Value: "+salestax,("<br />"));
var total = cost + salestax
document.write(cost + salestax);
Is there a JavaScript method to convert a "plain" number into a decimal one?
Say: 12345678 is converted to 12.345.678

I have a Java form where I need to be able to switch a drop down with a text box using Javascript. The change would be made depending on the radio button choice the user makes. The drop down is the default form element and radio button A is checked by default. So when the user clicks radio button B the text box should appear and if they change their mind and select radio button A the drop down should come back.
Whats making this a little tricky is that I'm doing my form validation using Java via the form element name. So these two will have the same name. I need for the drop down to be switched off/disabled if they have radio button B and vice versa. Is all this doable using javascript?
I've search far and wide for an answer, so forgive me if this is a
stupid question. (Well, it probably is.)
Consider the following javascript:
var foo = new Image();
foo.src = "http://some.server.com/some_filename.gif";
Now, the browser will retrieve 'some_filename.gif' from some.server.com
and put it into the object foo. What I want to do is then subsequently
analyze the actual binary data contained inside some_filename.gif.
(Specifically, I just need to look at the first few bytes.) Is there
any way to do this in just JavaScript?
I am looking for the best performing solution for modifying and
iterating an object graph in JavaScript. I have outlined below a
simplified example of the object model and examples of how I will be
using this graph.
Object model:
Two objects, [BadApples] and [GoodApples] each contains a collection of
[Apple] items (500 max). [Apple] simply has an ID and a name.
Requirements:
A quick way of determining whether a certain apple exists in either
[GoodApples] or [BadApples] (by ID).
A quick way of iterating through [GoodApples] and [BadApples] in order
to update the web page.
A way of moving a certain [Apple] (by ID) between [GoodApples] and
[BadApples].
I currently have this implemented using arrays, but iterating these
arrays is expensive. Is there an implementation of a binary-tree for
JavaScript? The real-world application may contain many hundreds of
nodes, and performance is crucial.
I'm trying to get the binary data of an image object.
I've found articles to writing binary to be the source of an image, but they don't tell you how to do the reverse. Pretty much, after the page loads I want to do something like.
myImg = document.getElementById('cow.jpg');
binData = myImg.somethingToGetBinaryDataPlese
For those that are curious why I'm doing this its for another project I'm working on where I store the binary data somewhere else after load, but for technical reasons this has to be done client side for if I do it server side I'm not getting the results I need for this project.
I'm reading the content of a local binary file with the method mentioned here: [URL]
Then I'm getting the data as a string where each character represents the binary value. I have successfully sent that string with Mozilla's XmlHttpRequest's sendAsBinary method, but IE 7's version doesn't have that method...
Using the send method almost works, the only problem is that binary content can be represented as the asciicode 0. This means that the string read by sent is cut off as soon as it is encountered. That means that the part before the first NULL character (asciicode = 0) is successfully sent to the server.
The solution I have made right now is to increment each character's asciicode on the client side by one and decrement them on the server before converting the character to the binary representation. The downside with this is that the size of the data sent between the client and server gets larger than the original filesize. Ex: 8kb file grows to ~12kb.
According to my previous post with popups hanging, now I'm trying to bypass
this strange behaviour using loading JavaScript image not by image.src=URL
but straight away from stream using HTTP GET method.
The problem is, how to assign stream from downloaded image (ex. GIF89a) to a
JavaScript Image object ? Code:
Im trying to implement dynamic images on my site. Basically, there is a list box, and when the user selects an option, it calls a service that streams back a base64 encoded image that will be the preview of what they're looking at.in FF you can do this: img.src = "data:image/png;base64," + args ; This doesnt work for IE. from what ive learned, IE doesnt support this type of inline coding.
I was thinking that maybe the next best solution would be to convert the base64 back into binary, and set the new image object to that source. something like this:
Code:
var img = new image();
img.source = binarydata;
now obviously, img.source isnt a real method. but i would like to be ale to set the binary data as the image.
possiblities: Is there anyway to save that binary as a file on the client? and then be able to reference that file as the picture img.src = "images/" + newfilename;
Some other alternatives is to stream back a reference on the server to get the picture, this would require two callbacks, which i dont want.
Also, there is a method of turning the image into a big array of HTMl elements, and each element holds a color, being a pixel. im not doing that, that is the biggest hack job i have ever seen.
I was looking at a page called Javascript: Convert Strings to Binary (and representing in a nerdy way!) where you can convert a String into binary dots using Javascript and I loved that, but how I can do that? Since the code isn't for making that grid...

I would like to create a program which converts some letters into different ones.
1) I want 2 text areas (input and output) + "convert" button
2) if I type in the input area the letters "ea" I would like it to be converted into "a", so that If I type "cambrea" and press "submit" the output text will have "cambra".
3) if I type "e " which is (e+space) I want it to be converted into " " which is "space" example: if I type the word "spine " it should be converted into "spin , note that there is a space after "spin ".
4) If I type any vowel before "o" it should render "o", example: gambuo becomes gambo.
would this be possible? I'm not very familiar with Javascript even though I can modify it.
I'm using a form on a page as a vessel for data, rather than to actually submit it. The reason is that the form is submitted to a service at www.rdbhost.com with it's special JS API, so I extract the data from the form manually and then feed the data to the methods from the provided library.
One of the field is a file. Calling ``.val()`` on it simply gives me the file name, but I need the contents.I've looked around, and found a few plugins that would actually send the file, but that's not what I want.
I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: [URL]. Here is my script:
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus

I'm gradually changing the color of some list items like this, but since i is decimal, I'm not getting the full Hex range. Is there a simple way to change i to Hex, so I go from 0 to F? Does jQuery have a function to do that?
