Validating Forms Input
Jan 6, 2006I 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?
JQuery :: Validating On Input Id Instead Of Name?
Mar 23, 2010I'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.

Mar 22, 2011I have a selection list that users can choose one value from about 300 different values. I wish to add some cross value vaidations to ensure some extra data gets entered should the user choose one of 50 of these values. Now I know I can write a JS validation individully fo each of the 50 as follows:
if theForm.field1.value=="25" && theorm.field2.value =="" {
alert("Enter field2 value");
}
Then repeat this alidation 50 times.
My question - is there a way to shorten the code to someting like this:
var fieldx = "1, 2, 3, 4, 5"; etc with all 50 values defined here, then something like:
if theForm.field1.value==fieldx && theForm.field2.value =="" {
alert("Enter field2 value");
}

Validating Quantity
Jul 23, 2005I 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.

Validating A Checkbox......
Jan 12, 2006I 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.
Validating Checkbox
Jul 20, 2005Can anyone explain why this code fails when the set of checkboxes

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");

Validating A String.
Jul 20, 2005I 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?
Validating The Sum Of Two Inputs
Aug 31, 2009I 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.

Validating Checkboxes By Value
May 3, 2006I 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?
Validating A Form Within Itself?
Jan 30, 2011I 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?

Validating Existence Of XML Tag ?
Apr 13, 2011I 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.
1st Way:
Code:
2nd Way:

3rd Way:

JQuery :: Validating After Load() ?
Aug 25, 2010I'm experimenting with the load() function. It works fine except when I try to validate (using jQuery Validate).
I have a page called "index.php" which contains the bulk of my code (including the jQuery validate call). The load function calls in a div from another page which we'll call foo.php. The page loads fine, but it just won't validate. I've wondered if you simply can't validate a "load"ed page, but I find that hard to believe.
Here's my code:
In index.php:

Validating A Variable Is Declared
Dec 7, 2006I have a situation in javascript where (this is inherited code, so I gotta deal with it) a variable is being used without being declared, as
someVar = someExpression ;
The original developer was relying on IE which automagically creates javascript variables for the IDs of all HTML elements, so somewhere in the HTML, there's
<someTAG id='someVar' >blah </someTAG>.
Unfortunately, in Mozilla (Firefox), I get a javascript error indicating that 'someVar' is not defined.
I wanted to check to see if the variable was undefined, then define it
if (undefined == someVar) someVar = document.getElementById("someVar") ;
this gives the same error in Mozilla (undeclared variable). I saw a thread with this exact problem, but it looks like its been archived. Does anyone have the solution to checking in javascript if a name is "undeclared" as opposed to "undefined"???
Validating A Form With Options
Jan 12, 2008I am helping someone out with a form. He wants the name required, easy enough, but then only an email or street address required. I have tried a couple of things and it is not working.
I am trying a very simple code:
<script type="text/javascript">
<!--
function validate_form ( )
{
valid = true;
if ( document.contact_form.name_mailing.value == "" )
{
alert ( "Please fill in the 'Your Name' box." );
valid = false;
}
if ( document.contact_form.address_mailing.value == "" || document.contact_form.email_address.value == "")
{
alert ( "Please fill in the 'Your Information' box." );
valid = false;
}
return valid;
}
//-->
</script>
Am I not using the or operator correctly? I only want to have the address or email required, not necessarily both.
