I have multiple checkboxes. How can I validate the group of check boxes so that a user can only select two. If they try to select more than two, an alert will pop up stating they can only choose two?
Code:
i have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.
<input type=checkbox name=name1 value=1>
<input type=checkbox name=name1 value=2>
........ get dynamically.
when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.

I have four html form check boxes.The user is allow to choose one or three of the check boxes, the last check box has a value of None.
Example: What's your favorite color.1. Red 2.Blue 3. Green 4. Gray. 5. None.The user can select more then one color.So I'm wondering how can I make the other check boxes deselect when the user click None.So if the user select None, then the other boxes cannot be checked. know you can do this with radio buttons but I would like the user to select more then one option.

I have two prompt dialogue boxes that ask the user the enter their name and their employee number.I am experiencing two errors. The first is, if a user enters their name incorrectly, using numbers for example, there is an error message that asks the user to re-enter their name using a string. If the user ignores the error message and enters a number a second time, the program accepts the entry, which it shouldn't.
The second error has to do with the employee number prompt. The prompt asks the user to enter an employee number that is equal to 6 digits, the program however accepts any number, less than or greater than 6 digits, which it shouldn't.I don't want the user to get away with entering anything incorrectly.

I have a code that I got from a tutorial website. The goal is when someone clicks the first check box with the value of yes then the two other sets of check boxes will autmatically be checked for no.
The issue is their are three sets of 2 check boxes each.
So here is my code code I am trying to use
PHP Code:
Here is my form code

So Ideally when a representative clicks that the customer has three services (clicks the Yes checkbox) all the other checkboxes will default to No.
How I would change the above javascript to do this.
I have this script that is supposed to check if a number the user guesses is the same as the randomly generated number.Problem is that the random number generated at the start of the program keeps on changing everytime I click on the "Check if I'm right" button, the random number gets generated again and I never ever get to reach the correct answer

View 5 Replies View RelatedI wanted to throw a quick and easy .js function into my comments section to ward off some spamming bots. I have a form in html that contains this table row.
The function I am calling sits in an external .js file. The file itself has a handful of functions but I will post the important bits below.
The form has other fields that validate just fine.
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.

I have to input an undefined number of rows of data. Existing data is read from a database. There is an Add button after the last row.
I can see how to add the next row: there is a hidden blank row with visibility set to 'none', which is turned to 'block' by clicking the Add button.
How can I continue to add rows? Do I need to have a large number of invisible rows and turn each one on as required? (I don't want to have to submit the form for each row, which would be another solution).
