Function - Checking Input Box For Numbers And Letters
Apr 24, 2011
This is my program:
And my question is how to make it display error if I have entered letters in the age box or numbers in a name box? Currently I have only if it is different from 1, so what should I write instead of 1 ?

I have this great piece of code that only allows letters in a form, however, it waits for you type the number and then gives it a null value (i think). If I wanted it to totally block any number keys (etc), how would I change it? AND, is there a way I could do this to only allow numbers?
function validLetters(f)
This code below totally blocks letters and signs! How would I apply that to the top code?
function validNumbers(myfield, e, dec)

I have an array which is populated by a count of instances from another array, so its ends up with data like:
I need to sort this by the number before the 'x'.
At present, a .sort() would put 1 - 9 before anything greater than 10, obviously not what I'm after.
How can I make it put this array into the correct order (e.g 22 x something else, 17 x another event, 5 x that event, 2 x this event)

I am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'

I am currently trying to build a new function in javascript that is supposed to handle a string of text. The idea is that it should find the lowercase letters and uppercase letters in a string and then swap them.
Meaning all lowercase letter becomes uppercase letter and vice versa.
So i am just asking if someone could point me in the right direction or give some tips. I've currently been reading about the toUpperCase(); and toLowerCase(); functions and i am fairly confident i know how to use them for switching, however i still need a way to find the lower , upper character in the string so i later can switch them.

I have a javascript function which checks if the user has enteed certain text into an input or if they have entered any text at all before the submit button which submits the text is able to be activated. How can I enhance this so that if the user no text at all and only enters several spaces this will also not be allowed and will return false?

I am wanting all the inputs of the table cells turn red when invalid data (in this case anything other than a number) is entered. Object:
1. To add a className to those inputs
2. With the new className 'invalid" the CSS gives a red background to the input The appending of the className is not showing up in the generated source code and both Firefox and Chrome is not showing any errors in the code. I can't not figure out what is preventing the execution.

that a simple question, I hope. I have an input (<input type="text" />) on my page, and I want it to only accept numbers, so if the user types anything that's not a number, it will be removed instantly. A simplified example just to illustrate:
<body>
<input type="text" name="numbers" /> <!-- I want this input to accept
only numbers -->
</body>

I am trying to add these 2 numbers as the form input. When I add 5 and 5 it returns 55 instead of 10.
Code:
var a = document.f.children.value;
var b = document.f.totalguest.value;
var c = a+b;

the validate plugin at the form at the below URL is validating as true as long as the first required input is valid even though subsequent required fields are invalid. It even gives the invalid class to all fields correctly but the submitHandler function is triggered anyway. I have an alert trigger when the form successfully submits and a little more output for firebug if you want it. [URL]

I have searched the internet and couldn't find a problem regarding this issue. The thing I want to do is simply validate a text input so when you enter a number in it, it won't validate and give you an error message. This is the code:

I'm creating a page that calculates a number depending on what value is inputted into a text field. I need to create some javascript that updates this new calculated value and outputs it next to the input field. Anytime the user changes the number, it recalculates the value. My calculation is currently being produced by PHP, however if I need to, I can create javascript as well to recalculate these numbers.

I'm trying to create a 4 x 4 array filled with numbers input by the user. I then need to rotate the grid clockwise like I've shown below.
01 02 03 04
05 06 07 08
09 10 11 12
13 14 15 16
13 09 05 01
14 10 06 02
15 11 07 03
16 12 08 04
I made all numbers double digit just for show in the example so the table is easier to read. So far the code I have is just trying to create the array and fill with numbers from the user. This asks for a number once then doesn't display anything at all.
<html>
<head>
<title>Rotate Array Matrix</title>
</head>
<body>

I am not new to jQuery but I just want to ask the best way to approach this. Basically I have a textfield in which the user is going to type in a number (for example 20) and after this textfield lose focus jQuery will be triggered to create whatever number of textfields the user put before (in this case 20).
So, to illustrate: How many users do you have: [ 2 ](and after the field above lose focus, the below will be generated)
Fullname: [ ]
Fullname: [ ]

I am trying to setup a textbox to only accept specific keys. The problem is, some of the Function keys are reading as the same values as letters.Ex.
112 - F1 - p
113 - F2 - q
114 - F3 - r[code]....
Is there another way to allow the function keys without enabling all matching letters as well?

Is there some way to determine if the XML returned via a $.ajax() call is well formed? My experience is that if badly formed XML is returned (eg: a missing ">") then the return value is "success". However I notice that data.childNodes[1].textContent contains a very specific error message that points to the line which has the syntax problem. Is there any (documented) way to know if the "success"-ful call to $.ajax() actually returned a poorly formed XML file?

Basically I'm going through and renaming div id's, etc to manipulate later in functions.I'm using jQuery's detach() which is working but for some reason my while (now for loops) are not working and providing me with bogus numbers.
Code:
var arrayFights=[0,1,2,3,4,5,6,7,8];
var counter = theBox; //where to start in the array
//first change numbers larger than counter
for(i=1;i<fights;i++){
arrayFights[counter] = i;
counter++;

I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.

What's supposed to happen is when the program is run the user clicks on "Select your Numbers!" their then asked for 5 numbers which they input and then the numbers are checked by a function called �isAlreadySelected� for duplicates and if there is an alert is shown. When 5 numbers are entered correctly then they are shown by a window.alert.
Its done in to 2 functions
When I run the below code I'm prompted for the 5 numbers but it isn't checking for duplicates and my selection is undefined.

I have a list of products where they have minimum quantities in a hidden input. Some products have multiple colours, though the same minimum quantity and I'm trying to implement a jQuery check that entries made are at least equal to the minimum.
Blank or '0' entries are fine but if it's below the minimum quantity it should set to the minimum.
HTML:
Is there something obviously wrong with this? It isn't performing the minimum check and I'm really not sure why.
