I have another problem (Im not very handy with javascript).I want to check if a value entered into a form is a whole number. This means it cannot contain a decimal.I wanted to use isNumeric() but realised that allows for decimals.Is there a way I can make sure a value is simply a whole number (0-9)
View 5 RepliesI'm trying to do this with PHP, although I think it would be easier if I used JavaScript, or maybe the same, I'm not sure.
If a user enters a value into the textbox, I want him to be able to move on only if it's a number, otherwise have text come up next to the textbox saying that he should enter a number.
I have got this xml file which has a background params which is <background>igmp:
{theme.background_video_ip}:1234</background>.
I have done the validation to check if the igmp protocol is used like this
if (clientSpecificData.background.substr(0, 7) == "igmp:") {
Right now I am trying to find out how I can use regular expressions to check whether a port number is used at the end.
I'm building a site that requires user registration, I've already built myself a PHP based user registrationg system, and it already has all the usual checks that are required before letting someone sign up (i.e. that the username is unique, that all required fields are filled, that the two passwords match, that the email address is valid, etc..) using PHP, and so I could ship the system as it is.. but.. I wanted to add some JavaScript checks to it aswell (just to be sure, and to save processor power, etc.. you know how it is). Code:

Questions:
(1)I wanted to know if code this script so that instead of the phone number appearing as: (123)456-7890
So that it appears as: (123) 456-7890 with a blank space after the ")"
(2)If that's simple, is there a way to error-check it so that only numbers can be entered into the phone number input field?

View 1 Replies View RelatedIs there way to make it to where if someone clicks one check box the rest get checked without knowing the names of the other form names? Meaning if I load a form with a dynamic number of entries, maybe it will show 8 check boxes or perhaps 6 and I wont know the name of the form fields. So is there a way if they click one main check box the rest get checked?
View 1 Replies View RelatedI am allowing a user to selected a date to schedule an event and it
seems like the best way to do this is with drop down menus for Year,
month, date. However I would like to make it so when you choose a year
and a month the appropriate days for that month show (i.e. 28 days if
you chose February 2006). I can easily do this with a loop if I can
find out what month the user has selected, but I can't seem to find a
way to get that value. Is there a simple javascript solution to this
problem?
I'm currently learning many web programming languages and figured this would be a good way to learn more and do things better. I have been working on a contact form for my website. I had originally did the error checking in PHP, but I would like to change it to JaveScript since this is the preferred way. I have it all semi working,It seems like I have some unnecessary variables and such.. I would like to clean it all up as best as possible.

I am having some trouble with my code in that I am trying to take the value from the date of birth field and check to see if over 18 years old. I they are not over 18, a window.alert dialog box pops up to tell them. Below is the check if 18 validation.
Script section in the document head:
//check if over 18
function overAge(){
var age;
[code]....
Code for body section:
Date of Birth: <br/>
<input type = "text" name = "date" value = "(mm/dd/yyyy)"/>
What I am wanting to do is have my form open up a new part of the form when the previous sections are filled out. i.e name field shows, when it has content, the next field opens up for it to be filled out, and so on.
View 3 Replies View RelatedI made a contact form for my website originally in PHP. I wanted to change it to JavaScript because that is the preferred way. Originally I had the form in my HTML file using a separate PHP file for error checking. For JavaScript do I have to make a separate page and call to it like the last time? I have put it all on my HTML page and where it was calling for the php page, I also put the JavaScript code. When I go to my site, the error checking is not working at all. There must be something wrong, but I haven't been able to point it out and I am very new to JavaScript. Also, when I go to my page and right click for the source code, the JavaScript I have in there does not show up. Below is my HTML code.
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html xmlns="[URL]">
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>Contact_Form</title>
</head>

I'm wondering if there is a way to check if a form is valid withouttriggering UI feedback for invalid fields in the form? I tried boththe $('#myform').valid() and validator.form() methods, but they bothtrigger the UI.
View 6 Replies View RelatedIs there a way for a JS script to detect the number of the form in which the script resides?

I have a form and select menus. I am posting it ajax post method and loading the same page with load method as you see in codes. There is a random number genarator. I want to change this random number once a click submit. If i do not load the same page this number does not change. Therefore I use both post and load methods like in demo. However when i do like this there is a problem which is random number have been generated twice somtimes. If you click submit button successively you will see that the number on left top corner sometimes changes twice a click. Why it is so and how can i correct it.

This is what I have so far, it is a template I copied from my working E-mail validation. I'm assuming I have to make it so it's just an array of numbers but I really don't know Java too well.
Essentially I just want numbers only to be accepted into the phone field. code...

Is there a way to retrieve the DOM element number in a form? For instance if I had 5 checkboxes with the same name and an event was fired to gather data, could I determine the DOM element number for each checkbox checked? I know this may seem like meaningless information, but I need it to do some other work on the page.
