Convert Input Field Value To Integer?
Mar 3, 2010
This should be simple, but it's not working for me! The relevant code is beneath. This code is on my html page directly under the input field:
input = document.getElementById('hiddenInput');
var inputInt = parseInt(input.value);
if (inputInt != 0) {
setClick(inputInt);
}
(I've tested it to make sure it sees the input object and that it has the correct value. It does call the setClick function appropriately, too.) This code is in a javascript file called in the <head> of the html page:
[Code]...
setClick() and resetAll() work great when I hook setClick() up to a link. When I try to grab the value from the input field, it doesn't even call resetAll(). I've assumed that it's a problem with converting the value to an integer, but I could be wrong. Does anyone have an idea as to what's going on?

function calculateGst(exGst) {
//percentage of current gst.
var gst = 10;
var gstAmount = (exGst * (1 / gst));
var gstInc = (exGst + gstAmount)
alert(gstAmount);
alert(gstInc);
}
now, the exGst parameter comes from an document.getElemenetById('txtExGst').value in an onclick event.
the problem is this. if 400 is entered at exGst, the gstAmount spits out 40, as it should, but the gstInc spits out 40040...so its treating it like a string rather than a number...

Does JavaScript have an easy of converting an ordinary integer like 135 into a time format like 02:15? I'm working on a timer that handles the backend with just a plain integer that counts down every second but it needs to output looking like a clock.

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.

What expression would I use to validate a field's data - that cannot be anything but an integer?
An empty field is also invalid, or one with a space in it.

I have already done a number of things with Jörn's validation plugin and I'm excited about its features. But here is my question: how do I validate a field so that it fits the two following conditions: it should be an integer and should not be equal to zero? So, if a user enters "0", it should be error; if he/she enters "12.5", it should be error also; but "-3", "125", "40" are OK.

First script, 'xxx.js' returns value 'document.write('integer');
So in HTML:
<script language='javascript' src='xxx.js'></script>
will write ie. 123 on my page in browser.
Can I get this integer or text 'document.write('integer')' to variable in
another script? So it would be something like this:
<script landuage='javascript>
a=<script ... src='xxx.js'></script>;
a*=20;
document.write(a);
</script> ...

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.

I am trying to learn how to do this one thing with JavaScript and can't seem to find anything on the internet. I have learned about loops and arrays and some other useful stuff. I've been looking for 2 days straight. I have gotten close though.
I am trying to have a textbox on the page and a button below it. A statement above the textbox should ask the user to enter a positive integer and then click the button. When the button is clicked the results from 0 to that number should appear below the button. Should look like this
please enter positive integer.
6
BUTTON1
1
2
3
4
5
6
I have been trying night and day for 2 days now and It's driving me insane.

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

So I have to ask some stupid questions and make sure that there is not something wrong in this simple syntax. I am trying to get input field attributes type and tagname by field ID. Heres the code..
Code JavaScript:
var type = $('#' + input_id).attr('type');
var tag = $('#' + input_id).attr('tagName');
When I look in firebug I see there is the correct ID in input_id variable and that the input field with that id exists. But for tag and type variables I just get 'undefined' for reason unknown.. syntax is correct or?

I'm trying to replicate a feature found in hotmail, facebook, etc. When you type or select a recipient from an auto-suggest box for your message/email that recipient's name is put into the "To" field box and is encased (usually a blue rounded corner box) with a X to the far right. If the "X" is clicked the recipient is removed.
How can do you put the selected recipient into the encasing and insert it in the "To" field box? If there are multiple recipients how are they differentiated? For example, if there were a ";" between the recipients the semi-colon would separate the values.

I have a problem created by my complete [rookie] status – only second time venturing into jQuery. I created a simple shopping cart using php and the PayPal buttons (1: buy now, 2: add to cart). The php back end does it great, it generates the table and the buttons and everything works just like it’s supposed to; Except, I forgot to add sizes. So I found out what I need to add, and I realize that the way the buttons work, I will have two different text boxes for size. Not very visually appealing, and since I’m not submitting this to the server before it goes to PayPal to pay, I cannot modify it with php the way I normally would. jQuery / javascript are my only hope of making this work. What I want to do:Have a single textbox where [size] is entered by the user.
Copy the value from the [correct] text box to the Value=”” section of the now hidden field in the PayPal form That way, no matter whether they [BUY NOW] or [ADD to CART] the right size is submitted to the PayPal shopping cart. This is the actual PayPal code that I’m trying to change
<table>
<tr>
<td>
<input type="hidden" name="on1" value="Size" maxlength="200">Size</td>
[code].....
I got this far, and then decided to find how to insert the "enteredVALUE" into the right place in the input text field (what I called output) and I've not been able to figure out how to stuff it in there.
