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'm using this function to allow only numbers to be written in a textbox, however i want to allow lowercase "a" and "b" also with the numbers.. is it possible with this function?

i want a value search(find) to database(table), this requires an ajax call to a server page? if want show result search live(online) and search letters to letters (transliteration), how is it?

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 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.
I want to make few forms but 1 submit button. I want to do 1 page , 5 forms , 1 submit button so when i click on the submit button it will send the 5 forms as 1 form.
View 2 Replies View Relatedhow to add forms in javascript, but it's limited to text input forms.
<script type="text/javascript"><!--
function updatesum() {
document.form.sum.value = (document.form.sum1.value -0) + (document.form.sum2.value -0);
}
//--></script>
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.
<input type="button" value="D20" onclick="this.form.display.value = Math.round (20 * Math.random())" class="buttonHi" /> <input name="display" type="text" size="6" value="" />
This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.
I need to modify the script showed at: [URL]
Right now it allows entering "numbers only", I need it so that it allows numbers and alphabets only, no special characters or spaces.
And yes, one more question, does the first part of the code need to be added in the <head> of the document or <body> ?
The code at the above URL is as follows:
<script type="text/javascript">
// initialise variable to save cc input string
var cc_number_saved = "";
</script>

I need to use javascript's graphics API to draw the letters of
the alphabet. If necessary, I can map out all 26 letters myself
and use drawline() to draw them, but I am hoping someone out
there might have a better suggestion. The user will click a spot
on the canvas, and the script will draw one of the letters at
that spot.

View 1 Replies View RelatedI'm working on a site, which will include a registration form for users that wish to register. In this registration form I would like it to have an AJAX based effect, such that when the user types each letter out for his username in the field, his username will appear (letter upon letter) itself.I've done my research, but had little luck. I'm sure it is possible as I've seen it before in a slightly different manner.

View 5 Replies View RelatedI'm trying to change the colour of the letters that have a link. Anyway it is not working correctly on Jquery
//Jquery
$("a").mouseover(function(){$().html(<a href="http://www.google.co.jp/"><font size="7">linktest</font></a>
[code]....
Basically, I am wrapping a span around each letter of a link element, so i can apply a random class to it - thus creating a rainbow effect on text. My sticking point is that successive letters can't be the same colour, nor can the first letter of successive links.
So 'Link1' wouldn't be acceptable as L and i have the same colour, nor would 'Link1 Link2' as the two L's have the same colour. Also, the code I'm using to append the spans to each letter is also appending a span to any spaces in the links, is there a way I can stop this? I've attached all the files I'm using.
On the example I've attached, I have made each links first letter successive, so the colours will never be the same. I've also made spans from the second letter onwards so they'll never be the same - but occasionally it'll throw up a clash where the first and second letters of each link are the same colour.
I'm new to Jquery, and i was wondering how i could rename a string like "hat" to "het" by replacing "a" with "e"in my labels..
