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 am going to validating a checkbox which is created dynamically that means the field name is not fixed everytime .Here is my html code
HTML Code:
<tr>
<td class="Cat" bgcolor="#cccccc" style="padding-left:10px; border-bottom:1px solid #ffffff;">Computer<span style="color:#fff;">*</span>
</td>
<td style="padding-left:10px;">
laptop<input type="checkbox" name="n5_Computer[]" id="n5_Computer[]" value="laptop" />
[Code]....
I have the checkbox validation. I have it set onClick, this works perfectly with both the mouse click and also if the space bar is used to select the option, which is great. However if a user simply 'tabs' over the option it doesn't validate real time. The solution I came up with was adding a onKeyDown event to trigger the same function.
Code:
<input type="checkbox" id="M_TERMS" name="M_TERMS" value="1" onClick="vldTERMS(this.id);" onKeyDown="vldTERMS(this.id);">
Why my email field is validating, but mycode for validating empty fields is not?

If it is possible, how to reflect popup checkbox changes on same checkbox in parent window. Main windows contains a list of thumbnails, each one with a checkbox. Clicking on a thumb, a popup window is opened containing a bigger photo beside a checkbox. If the user checks/uncheks it I want the thumbnail checkbox in parent window to be changed in the same way (and onclick tasks to be performed). To achieve this I am using cookies and onClick -> parent.reload.

My JSP web page has many checkboxes. What is web page source code look like when clicking one checkbox will submit only one checkbox value (not the whole form) immediately? i.e. toggling one checkbox will send the info that only that checkbox is toggled. This does not work because clicking one checkbox will send the whole page

View 2 Replies View RelatedI 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 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.

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 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?
