JavaScript - Alloving Only Numbers Plus Two Letters In A Textbox

Hi all,

I'm trying to change our shopping cart code by making a small modification.

When editing a product, there is a dimensions box which currently only allows numbers. We want it to allow numbers and letters (don't ask why).

The code we have is the following which we think is related to why our shopping cart won't allow letters in the box.

Could someone please edit the following code to allow letters? Thank you.

Code:

		if(isNaN(dimensionsFormat(prodWidth.value)) && prodWidth.value != "" && !sellingDP) {
			ShowTab(0);
			alert("%%LNG_EnterWidth%%");
			prodWidth.focus();
			prodWidth.select();
			return false;
		}

		if(isNaN(dimensionsFormat(prodHeight.value)) && prodHeight.value != "" && !sellingDP) {
			ShowTab(0);
			alert("%%LNG_EnterHeight%%");
			prodHeight.focus();
			prodHeight.select();
			return false;
		}

		if(isNaN(dimensionsFormat(prodDepth.value)) && prodDepth.value != "" && !sellingDP) {
			ShowTab(0);
			alert("%%LNG_EnterDepth%%");
			prodDepth.focus();
			prodDepth.select();
			return false;
		}

Hey everyone

Okay so...
I'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 below, at the end of their unique url.

To explain further:-
Say I type my username to be Owen
Below the field I would like it to display:
http://www.mydomain.com/Owen
http://Owen.mydomain.com/
As I type it. Is this possible?

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.

Hope you can or are willing to help

Thank you

I have a document list of several hundred drug names where some are lower case and some are all caps. I want to bold only the lower case drug names but don't want to do it manually. Is there a java script that I can apply where it automatically does that for me?

I am trying to make a JavaScript chat-bot

I was using this to answer a month questions and it worked fine for what is the month after


DatesA=new Array("january,February","february,March","march,April","april,May","may,June","june,July","july,Aug ust","august,September","september,October","october,November","november,December","december,January ");

if (input.search("what is the next month after")!= -1)
{document.result.result.value = "Sorry, I don't know.";
for (i=0; i<DatesA.length; i++) {
Date=DatesA[i].split('=');
if (input.search(Date[0]) != -1) {
document.result.result.value = Date[1];}
}
return true;}

What is the month after May
answer: June

however it didn't with letters. Is there a way to write this to prevent the wrong single letter and small words from triggering

Letterbefore=newArray("b=a","c=b","d=c","e=d","f=e","g=f","h=g","i=h","j=i","k=j","l=k","m=l","n=m", "o=n","p=o","q=p","r=q","s=r","t=s","u=t","v=u","w=v","x=w","y=x","z=y");

Then use this:


if (input.search("what is the letter before")!= -1 || input.search("what letter comes before")!= -1)
{document.result.result.value = "Sorry.";
for (i=0; i<Letterbefore.length; i++) {
Letter=Letterbefore[i].split('=');
if (input.search(Letter[0]) != -1) {
document.result.result.value = Letter[1];}
}
return true;}
.

The bot correctly answers for x y and z . It then answers V for all other letters, digits and short words

What is the letter before cow
answer: V

Thank you for your time

I'm working on a script to check password strength "onkeyup",so when the user enters a password after every character i call a function to check the passwords strength.I'm almost ready,but i stucked with one thing:
I want to check the same characters in the password,so i can deduct some point from the score if there are identical characters.
Here is my code:
PHP Code:
var multis = 0;
        for(var x = 1; x < passLength; x++)
            {
                actChar = new RegExp(password.charAt(x),"g");
                multis += password.match(actChar).length;
            } 


I know it seems an easy task,but i've spent at least 6 hours with it,(the first pitfall was that i didn't know the RegExp function and took my variables into the match() function,i think you can imagine the results)and i just can't figure this out,i always get crazy results,i've tried a few more versions as well without any luck.
Thx in advance for anybody who can help me!

Hi wise javascript gurus, I am working on a small form that on the click of a button, it calls a function to validate a string that consists of 3 portions delimited with a dash("-") in the following format
XXX-NNNN-XXX
where X are letters only
where N are numbers only

I have to use regular expressions to validate the first portion and verify that its exactly 3 characters long that are letters only

if the first portion or "plant code" is larger then 3 characters long an alert gets display

also if the first portion contains alphanumeric or numeric characters an alert gets displayed, the first portion has to be in letters only.

down below is my code that is not functional at the time because I know for sure the way I check for regular expressions is a bet washy but thats the only thing I was able to come up with, any help will be appreciated.

thanks for making time to read my thread

Code:

<html>
<head>
<script type="text/javascript">
function validateit()
{
	var number = document.myform.product_number.value;
	var charnum = number.length;
	if (number =="")
	alert("you must enter a product number, field cannot be empty");
	
	else if (charnum < 12 || charnum > 12)
	alert("the product numbre has to be exactly 12 characters long");
	
	else
	
	validate_number(number);
}

function validate_number(num)
{
	var objRegEx = /^[a-z]+$/;

	split=num.split("-",3);
	if (split[0].length!=3)
	alert("the Plant Code portion of the Product Number has to be only three charactes long")
	if!(objRegEx.test(split[0])
	alert("the Plant Code portion of the Product Number has to be letters only")
}

</script>

Hi all,

Forgive my ignorance, I'm quite new to Javascript...

I'm looking to do two things: the first is to move elements of an array to the next index using a function. I have managed to do this like so:

Code:

var letters = ['h','i','j','k'];
function moveElements(anArray){

var newArray = anArray;
newArray.unshift(newArray[newArray.length-1]);
newArray.pop();
}
moveElements(letters);

(this may or not be great, but it seemed to work) ... but I want the original array to reset to its original state if the function is called again (thus producing the same answer as opposed to shifting the elements again).

Secondly, and this is the bit I'm really struggling with: I want to compare each letter of a string to elements within an array and display the indices. For instance:

Code:

var myArray = ['a', 'b', 'c', 'd', 'e', 'f'];
var text = 'dead';

Hence I want the result '3,4,0,3'.

I know the answer will use for and if statements but I can't wrap my head around it at all. Help would be appreciated, thank you.

Hey I'm trying to make a script which will check if the string which the user sent from a form contains ONLY letters. The problem is if the user entered something like this "25 years old" it allow that to be submitted. It only blocks submissions of the form if the user submits NO letters like this "12345". I want it to block submissions if at least one character isn't a letter. Here's my code:

Code:

var message = document.myform.formtest.value;
var allowed = /[A-z+]/;
if(!allowed.test(message)) {
   alert("The field only allows letters (a-z).");
   return false;
}

Hi,
can anyone tell me how to detect any word (a-z only, surrounded by whitespace) less than 5 letters long?

Edit - this is what I have currently:

Code:

var RE=/\s([a-z]{1,4})\s/gi;
var string="some words"; //should be turned to "words"
string=string.replace(RE, "");

This is taking 4 letter chunks from the end of words.

Cheers,
Gus

Edit - fixed (replaced \s with \b)

Hay!

I have a silly question, I have a row of numbers, 1 to 250. The numbers are all in one horizantal line. But I want to use a <br> after every 10 numbers.

I tried:

if(i % 10) {
document.write("<br>");
}

This is how I wanted to be:

1, 2, 3, 4, 5, 6, 7, 8, 10,
11, 12, 13, 14, 15, 16, 17, 18, 20,

Does any one know how can I achieve this I'm still a noob.

I have written below code to except only number in a textbox. This is working fine. However, When I'm copying and pasting, then it is taking non-numbers.

Code:

<html>
    <head>
        <title></title>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

        <SCRIPT type="text/javascript">
     
            function isNumberKey1(evt)
            {
                var charCode = (evt.which) ? evt.which : event.keyCode
                if (charCode = 46 && charCode > 31 
                    && (charCode < 48 || charCode > 57))
                    return false;

                return true;
            }
     
    
     
        </SCRIPT>
    </head>
    <body>
        Phone number :
        <input type="text" id="phonenumber" onkeypress="return isNumberKey1(event)"  maxlength="10" size="15" > <br /> <br />
        Alternative number: 
        <input type="text" onkeypress="return isNumberKey1(event)" id="alt" maxlength="10" size="15">
         <input type="button"  value="Submit">

    </body>
</html>

say cutcost2 is 10 and qty is 25

Code:

document.profile_quote.cuttotal.value = eval(document.profile_quote.cutcost2.value + document.profile_quote.qty.value) .toFixed(2)

the output i get is 1025 rather than 35. what have i got wrong?

thanks

I'm trying to teach myself Javascript to prepare for it next term. I asked earlier how to add together the numbers 1-10 in a loop. Now I'm wondering how can I change the 10 to be a valuable I input. Basically I want to be able to enter a number on the page or in a message box then I want the code to add all the numbers from 1- the number I enter.

The code I got from my previous thread is he
Code:

<html>
<head>
<script type="text/javascript">

var varX = user input;
function sum() {
   var varX = user input;
   for(varY = 1; varY<=10; varY++) {
      varX = varX + varY;
   }
   return varX;
}

var resultat = sum();
alert(resultat);         // show message box with result
</script>
</head>
<body>
</body>
</html>

Code:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
</head>
<script type = "text/javascript">
	
	var strCurrency = new Array(6);
	strCurrency[0]="Pound";
	strCurrency[1]="Marc";
	strCurrency[2]="Franc";
	strCurrency[3]="Dollar";
	strCurrency[4]="Nordic";
	strCurrency[5]="Fivesmon";

	var dblExchangeRate = new Array(6);
	dblExchangeRate[0]="1";
	dblExchangeRate[1]="74";
	dblExchangeRate[2]="8.54";
	dblExchangeRate[3]="6.25";
	dblExchangeRate[4]="98.1";
	dblExchangeRate[5]="1.32";

	function convertNumbers
	{

	}

</SCRIPT>

I want to see what the function would look like to be able to convert into different currencies by using arrays. I know that this would be a useless way to do it as they are updated every day, but it's for personal education purposes.

(Note: The website contained a textbox in which to enter the amount in pounds, a drop-down box allowing the user to select currency, a button to click to convert, and another text box showing amount of money after converting.)

Any help is greatly appreciated.
