I have the code for the form, it asks for the quantity of certain items to purchase and displays them. The next exercise I needed the Quantity to test for Numbers only. I need it to give an alert if there is a NaN entry and stop the program otherwise it continues on with the calculations.
PHP Code:
<script type="text/javascript">
var SalesItems = new Array ();
SalesItems ["Webcam"] = "50.00";
[code]....
I am looking for a little help validating a forms input. On the form are key
items which I do not wish to be zero length.
I have wrote the following function:
<script language=javascript>
function ValidateLength(oid, min, max)
{
var txt = document.getElementById(oid);
var length = txt.value.length;
if(length == 0)
{
alert("You must enter your reference, Company Name and Contact Name");
}
}
</script>
However their are still a few issues I would like to work out.
I all it with my forms sumbit event with the following:
<input type="submit" name="Submit" onclick="ValidateLength('txtRef',0,100)"
value="Submit Details">
However that will only check the length of the item txtRef, how can I check
more textbox values? Also how can I stop the form posting if the alert is raised?
This code will not work no matter what I do.
function comparePassword(){
pass1 = document.getElementByName('password');
pass2 = document.getElementByName('cpassword');
if(pass1.value != pass2.value){
document.getElementById('matchpass').innerHTML = "Passwords do not match!";
}}

All it's supposed to do is check whether or not "password" and "cpassword" match, if they don't it's supposed to put "Passwords do not match!" in the span "matchpass". I can't see anything wrong with the code and javascript is enabled in my brower. GetElementByName does not exist, so I switched it to getElementById and it works perfectly.
It doesn't appear to be possible to validate multiple forms on a pages that only has a single <form> tag, using the JQuery Validation Plugin offered by Jörn Zaefferer. The reason I need to do this is because my pages are created with ASP.NET whose architecture generally calls for a single page-wide <form> tag. In my designs, I'd like to submit my data using a custom ajax call to a web-method, and link it to a click event on a button.
Below is an example:
<!
DOCTYPE
html
PUBLIC
"-//W3C//DTDXHTML1.0Transitional//EN" "[URL]" >
<
html
xmlns
=
"[URL]"
> .....
I'm not sure that I fully understand the documentation for the Validation plugin, but it doesn't seem like this is possible, as the plugin seems to need a <form> for each form.
I need a JS validation code for validating numbers such that,Empty space and characters(including + and -) shouldn't be allowed,there should be only one decimal point,spaces and characters between numbers also shouldn't be permitted.

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)

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 = "";

I have a function like this
function checkquantitiy(quantitiy){
if(quantitiy.value != parseInt(quantitiy.value)) {
alert(quantitiy.value+" sorry not integer quantitiy");
}
} //End of function
This check if quantitiy is integer. In the form I have following
<input name="buyquantitiy" type="hidden" id="buyquantitiy" value="<?php echo
$buyquantitiy; ?>" size="1" maxlength="3">
<input name="quantitiy" type="text" id="quantitiy" value="1" size="1"
maxlength="3" onchange="javascript:return checkquantitiy(this);">
The problem is when i will calculate if quantitiy/buyquantitiy is an
integer. The reason is that some products can only be seld as 4 items, and
if you press 3 wou should get a message that says
"Sorry a quantity of 3 are not aviable because there are 4 items in
package". Can transfer 2 varibales into the function? Or have anyone any
suggestion how to solve this.
I am a newbie to javascript.
I have an asp text box which I want to validate for the number of
characters entered i.e. I dont want user to enter more than 280
characters in the text box.
I have a form generated from a Perl script. The number of check boxes
on the form is unknown until the time the form is generated. The
names of the check boxes are created from some values in the database,
based upon other user input.......<crazy, I know>
The user must choose at least one check box.
So, how can I write a javascript routine that will perform checking on
an unknown number of check boxes.
Can anyone explain why this code fails when the set of checkboxes
consists of only one.
myForm.update.length returns 0 instead of 1 with the result that
I get an alert box even tho' the one checkbox is checked.
function checkForm(myForm) {
var numBoxes = 1*myForm.update.length || 0;
for(i=0;i<numBoxes;i++) {
if(myForm.update[i].checked == true)
return true;
}
alert("Select one or more part components to update");
return false;
}}
I have a requirement whereby I must validate that a string matches one of
several patterns:
1. An ISO standard 2 character country code (eg GB, NL) followed by five
digits.
2. An ISO standard 2 character country code (eg GB, NL) followed by an X
followed by five digits.
3. 3 characters in the range a-z followed by 3 digits followed by 2
characters in a specific set (eg MT, AT, DA).
4. 4 characters followed by a hash (#) followed by 3 characters followed by
3 digits followed by a hash followed by 3 characters.
5. 4 characters followed by a hash (#) followed by 3 characters followed by
3 digits followed by a hash followed by 4 characters.
I have been told that a better way to achieve this than using .charAt is by
using something called a regular expression, but I don't really understand
them. Can anyone please advise on the above or alternatively point me in
the direction of a suitable resource on these regular expression things?
I am trying to write a js that validates a form with two text inputs. The two inputs are: 'D_techA' and 'D_techB'. I just want to add up (sum) the two input fields (which must be positive numbers) and make sure that they add up to exactly 100 (not more and not less). If they do not add up to 100, then an alert should pop up that says "The two values must add up to exactly 100." I have tried and tried to write a js that does this validation (looking at numerous validation scripts posted in this forum and elsewhere) and I just cannot seem to make it work.

How can I combine these 2 functions?
function POvalidator()

return false;
}}
function checkCheckBox(){
if (f.agree.checked == false )
{
alert("Tou must agree to the Terms to continue");
return false;
}else
return true;
}
I found some simple code to get a better understanding of validating checkboxes. It validates the checkboxs by their name. Is it possible to validate the checkboxes with the same name but different values? The name of the checkboxes will be an array containing the values of the checkboxes selected.
I have my html like so:
<input type="checkbox" name="stuff[]" value="1" onClick="countChoices(this)">
<input type="checkbox" name="stuff[]" value="2" onClick="countChoices(this)">
<input type="checkbox" name="stuff[]" value="3" onClick="countChoices(this)">
And the javascript where I edited "box1=", "box2=", "box3=" is like so:
function countChoices(obj) {
max = 2;
box1 = obj.form.1.checked;
box2 = obj.form.2.checked;
box3 = obj.form.3.checked;
count = (box1 ? 1 : 0) + (box2 ? 1 : 0) + (box3 ? 1 : 0);
if (count > max) {
alert("You can only choose up to " + max + " choices!
Uncheck an option if you want to pick another.");
obj.checked = false;
}}
How do I correctly create box1, box2, box3, in this case?
I have a form that is passed to itself. I was just wondering if there was a way to get this to validate before it passed to itself.I was assuming that as the form doesn't properly submit, I could not use onsubmit="return sValidation()", so I have it on the buttons onclick. Correct assumption or not? Is there a way round this at all and to get it to validate?

I am creating this Javascript/XML HTA that is basically a project tracker. I recently added some new fields in the form that are written to the XML file for the project being tracked. This makes the files neither backwards compatible if I use it in a previous version nor forward compatible for future versions. This means if a user is using version 1, I create version 2, he wants to import his old tasks to Version 2, it throws an error. For example if I have a <status> element written in the newest version, but no <status> in the previous, I can no longer use that projects XML file in a previous version.
I tried to use the following code to validate existence of the tag and assign whatever outcome as the variable to write, but it's not working. Theres a few different ways I tried.

I'm working on a site where the name attribute of an input will not be known beforehand. I'd like to be able to modify or extend the validate plugin to set the rules and messages based off of the id of an input instead of using the name.
