JavaScript - Checksum Validation Problem!
Hello,
I 'm working on Euro banknote validation, where I'm using authentication of the serial number of Euro banknotes by the calculation of the "checksum". Basically what this algorithm does is to replace the first letter of the serial number by a number (each letter represents where the banknote is originally from), then it calculates the sum of all digits. If the remaining of the division of that sum by 9 is 0 then your note is valid. More info:http://en.wikipedia.org/wiki/Euro_banknotes#Checksum. Some test data. EURO Serial Number V44671133335 T27620110932 A00000000007 The last serial number "A00000000007" works properly. but the first two for some reason don't work properly. Those are my javascript codes: Code: <html>

Hi, I have got a validation problem in my javascript. The user needs to enter into "city" text box and also to select a state from a drop down list. The problem is that the function "checkValue" goes into the loop. Can anybody pinpoint the problem? Code: <INPUT TYPE='text' NAME='city' size='50' maxlength='50' id="City" onBlur="return checkValue(this),onchange= compLoop
<select name='state' class='dropdown' id="State" onblur="return checkValue(this),onchange= compLoop()">
<option selected value=''>Select a State
<option value="AL">Alabama
<option value="AK">Alaska
<option value="AZ">Arizona
<option value="AR">Arkansas
<option value="CA">California
</select>
<INPUT TYPE='text' NAME='zip' size='10'maxlength='10' id="Zip" onBlur="return checkValue(this),onchange= compLoop()">
This is the function checkValue() Code: function checkValue(textbox)
{
if(textbox.value==""||textbox.value==null)
{
alert("Please enter the value for "+ textbox.id);
textbox.style.background='pink';
textbox.focus();
return false;
}
else
{
textbox.style.background='white';
return true;
}
}

Problem is when I submit the form I am getting what you see in the attachment, I guess this email form which pops up needs to be directed to Yahoo Hosting then redirected from there back to me? Anyway I would like if it the email could be sent directly to me without this form popping up, is that possible? Also, when I submit the form with the fields empty I am not getting the error message? I have an issue with a form I am creating, I have many check boxs where at least one of the 2 needs to be selected and the final one has to be selected for the submit button to become active Code: <form id="form1" action="#" method="post"> One <input type="checkbox" name="value1" onMouseDown='submit_form()'/> Two<input type="checkbox" name="value2" onMouseDown='submit_form()'/> //atleast 1 of these 2 has to be selected Three<input type="checkbox" name="value3" onMouseDown='submit_form()'/> //this 1 has to be selected <input type="submit" name="submit" value="submit" id="submit" disabled="disabled"/> this is the javascript I have atm to do this Code: function submit_form(){
if (form1.value1.checked == false || form1.value2.checked == false) {
document.getElementById(submit);
orderForm.submit.disabled=false;
}
}

Hi, I am having problem in validating my form using spry tools. The problem is that if I try to include any other validation other than spry along with spry validation the spry validation does not work. Plzz tell a possible solution Hi folks this is my first post Edit: sorry for the incorrect title should have read simple javascript validation problem! i have a fair understanding of php and mysql and have never had to use javascript as i was secretly trying to avoid it. The time has now come where i want to use it for client side validation on a form. I am able to validate most of fields however i need to validate a date to check it has been entered in the following format dd/mm/yyyy and that the date is not greater than todays date. N.B the date is entered into a text field in HTML i wrote a function with lots of if/else statements and failed. Im 100% positive there is a far simpler way to achieve my goal any help would be greatly appreciated. Thanks Code: function checkDate(elem, helperMsg){
var day = elem.substr(0,2);
var month = elem.substr(3,2);
var year = elem.substr(6,4);
if(day < 01 || day > 31)
{
var invalidday = true;
}
if (month < 0 || month > 12)
{
var invalidmonth = true;
}
if (year < 01 || year > 2099)
{
var invalidyear = true;
}
if ( month==04 || month==06 || month==09|| month==11)
{
if (day == 31)
{
var invalidday = true;
}
}
if (month==02)
{
if (day > 28)
{
var invalidday = true;
}
}
if (invalidday || invalidmonth || invalidyear)
{
alert(helperMsg);
elem.focus();
return false;
}
else
{
var dd = today.getDate();
var mm = today.getMonth()+1;//January is 0!
var yyyy = today.getFullYear();
if(dd < 10)
{
dd='0'+dd;
}
if(mm < 10)
{
mm='0'+mm;
}
}
if (day > dd && month > mm && year > yyyy)
{
alert(helperMsg);
elem.focus();
return false;
}
else
{
return true;
}
}
Having an unusual problem with the simple validation script below. In my script, I want to validate the username text field so that if the value of the text field (i.e. the amount of characters in the field) is less than 5, it would show a message in the page using innerHTML. The script works, but in a roundabout sort of way, or at least that's what it seems to me. Instead of making sure that the amount of characters in the text field is less than 5, it seems to disregard this entirely and instead make it so that if it has no value at all, the message will be shown. If it has a value of even 1 character, though, the message does not show. Not what I was trying to do, and I really don't know what's happened. Thanks in advance to anyone who can help out a newbie in need. Code: function uservalidate() {
if (document.getElementById("user").value < 5)
{ document.getElementById("userdiv").innerHTML = "Username must be six characters or more." }
else
{
document.getElementById("userdiv").innerHTML = ""
}
}
Code: <body>
<form id="form1">
<input type="text" id="user" onblur="uservalidate()" />
<div id="userdiv"></div>
</form>
</body>

There is a checkbox in between these <div>'s which says "Same as Billing Address". It is used to populate all the shipping fields from the billing fields. Well, on this particular form there are some fields which are mandatory & which I have validated by jquery validation. I have used the $("#form_id").validate().form(); statement to check validation on the click event of the checkbox. The actual problem is that after page loads, I directly click on the checkbox & submit the page, the page gets submitted & validation does not execute. If I click the submit button with the checkbox unchecked then the validation runs properly. Why is my form not being validated if I checked the checkbox? Please guys, help me out. Thanks in advance. Bhavik. I am currently trying to fix a problem on the form submission on my site. On the Request Information page I am using MM_validateForm function and the FormtoEmail.php script. When required fields are blank, you are alerted via pop-up notification when hitting submit. Afterwards though, the form still sends without letting you finish completing required fields. I have noticed that if the First Name field is blank the form will not send, but any other field it just still sends. I have looked this up on Google endlessly and have tried every 'fix'. This is the function: Code: <script type="text/javascript">
<!--
function MM_validateForm() { //v4.0
if (document.getElementById){
var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;
for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=document.getElementById(args[i]);
if (val) { nm=val.name; if ((val=val.value)!="") {
if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');
if (p<1 || p==(val.length-1)) errors+='- '+nm+' Must Contain an Email Address.\n';
} else if (test!='R') { num = parseFloat(val);
if (isNaN(val)) errors+='- '+nm+' Must Contain a Valid Phone Number.\n';
if (test.indexOf('inRange') != -1) { p=test.indexOf(':');
min=test.substring(8,p); max=test.substring(p+1);
if (num<min || max<num) errors+='- '+nm+' Must Contain a Number Between '+min+' and '+max+'.\n';
} } } else if (test.charAt(0) == 'R') errors += '- '+nm+' Is Required.\n'; }
} if (errors){ alert('Please Complete All Required Fields:\n'+errors); }
document.MM_returnValue = (errors =='');
} }
//-->
This is the form html code: Code: <form action="FormToEmail.php" method="post" name="myform" class="cmxform" id="myform" onsubmit="MM_validateForm('first-name','','R');MM_validateForm('last-name','','R');MM_validateForm('workphone','','RisNum');MM_validateForm('address1','','R');MM_validateForm('city','','R');MM_validateForm('state','','R');MM_validateForm('country','','R');return document.MM_returnValue;">
This is the code on the submit button: Code: <input type="submit" class="buttons" onClick="MM_validateForm('first-name','','R');MM_validateForm('last-name','','R');MM_validateForm('workphone','','RisNum');MM_validateForm('address1','','R');MM_validateForm('city','','R');MM_validateForm('state','','R');MM_validateForm('country','','R');return document.MM_returnValue;" value="Send"/>
I may be missing something really obvious but i've gone over this for three days. I just recently have moved positions to Website Designer and my main background is in Graphic Design so my knowledge is very minimal. I created this site in a month due to time restrictions and the code is far from perfect. any help would be greatly appreciated. thanks! EDIT: sorry sorry, I just realized I posted this on the wrong place.... {palmface} Just to start off, Javascript is NOT my forte'. Ive been trying to do some form validating for a few hours now. I've tried many different combos and trying multiple functions to make this work but I have seemed to make more of a mess than anything now. Here's what I've got going on... A simple form with 3 text inputs a checkbox and a submit button. I'm trying to do 7 things. 1. strip special characters from all 3 input fields (except : / and @) 2. make sure no input fields are blank 3. verify that email has @ and . in it 4. insure that the checkbox is checked I would love to set the email not to allow certain domains(yahoo,gmail) but that is a bit out of my league. Any help would be appreciated, below is the current garbled mess of javascript I am left with after hours of trying to get it to work... my appologies. I know it's ugly. Code: <script LANGUAGE="Javascript">
<!-- Begin
function CleanUp() {
name = document.register.name.value;
email = document.register.email.value;
website = document.register.website.value;
var iChars = "!#$%^&*()+=-[]\';,.{}|\"<>?";
//remove crap name
for (var i = 0; i < document.register.name.value.length; i++) {
if ((iChars.indexOf(document.register.name.charAt(i)) != -1)) {
window.alert ("No special characters allowed.");
return false;
}}
//remove crap website
for (var i = 0; i < document.register.website.value.length; i++) {
if ((iChars.indexOf(document.register.website.charAt(i)) != -1)) {
window.alert ("No special characters allowed.");
return false;
}}
//remove crap email
for (var i = 0; i < document.register.email.value.length; i++) {
if ((iChars.indexOf(document.register.email.charAt(i)) != -1)) {
window.alert ("No special characters allowed.");
return false;
}}
//check required field
if ((name == "") || (email == "")|| (website == "")) {
window.alert("Please enter your Name, website, and E-mail address.");
return false;
}
//verify email
if (email.value.indexOf("@", 0) < 0)
{
window.alert("Please enter a valid e-mail address.");
return false;
}
if (email.value.indexOf(".", 0) < 0)
{
window.alert("Please enter a valid e-mail address.");
return false;
}
// check agree term before submit
if (agree.checked == false )
{
alert('Please confirm you are the site owner.');
return false;
//done
}else

I have two seperate js files. One that houses the functions mylibrary.js and another that call the validated functions myform.js. I can not get the form to validate any data. The data just sits there and will not report errors. Any help would be greatly appreciated. Code: function valForm()
{
if(!isAlpha(document.myform.firstname.value))
{
myform.firstname.focus();
return false;
}
if(!validEmail(document.myform.email.value))
{
myform.email.focus();
return false;
}
if(!isRequired1(document.myform.options.value))
{
myform.options.focus();
return false;
}
return true;
}
// JavaScript Document seperate js file mylibrary.js
function isNumber(num) { return !(/\D/.test(num)); }
function isAlpha(text){ return text.match(/\w+/) }
function validEmail(email){ return email.match(/^([a-zA-Z0-9]{3,})(((\.|\-|\_)[a-zA-Z0-9]{2,})+)?@([a-z]{3,})(\-[a-z0-9]{3,})?(\.[a-z]{2,})+$/i ) }
function isRequired1(){
if(myform.food.selectedIndex ==0)
{
alert("Please select from the drop-down list.");
}
}
