JavaScript - Validation Javascript Using Type

php has the $_POST GLOBAL that contains an array of all the POST form variables. Does Javascript contain something similar built in?

Hi,
I have an array in JavaScript. How can I GROUPBY Branch, then by Client and then by Referral Type and COUNT DISTINCT LPS # in JavaScript. Please note I need to do this client side using JavaScript.

Array Data:

How do you make an ios5 type notification system with javascript for your webpage?

I am new to this forum.. and I am hoping to get help with this javascript validation for my form for my assignment. trying to validate multiple fields. I have never done javascript, so with my limited understanding from Google, I put together code snippets.

Problems:
1. How can I get one message box when the user presses submit indicating all failed validation at one time
2. The expired credit card validation doesnt work
3. Cant seem to find a good "confirm password" script
3. The form does not submit if all the fields are correct.


<script language="javascript">

var byr;
var age;
var now = new Date();
tday=now.getDate();
tmo=(now.getMonth());
tyr=(now.getFullYear());

{
if((tmo > bmo)||(tmo==bmo & tday>=bday))

Hi. I am trying to do some sim[ple form validation using javascript. I have a simple html file
Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Send Card</title>
<script language="JavaScript" src="gen_validatorv31.js" type="text/javascript"></script>
</head>
<body>
<form action="getName.php" onsubmit="return validate_form(this);">
Receiver (To): <input type="text" name="name"><br>
Sender (From): <input type="text" name="sender"><br>
Email: <input type="text" name="email"><br>
<input type="submit" value="Submit">
</form>
</body>

</html>

Which calls up my javascript and php file (The php file should only be used when the javascript has found no errors).

Now I have a js file which does some validation
Code:

<script type="text/javascript">

function validate_required(field,alerttxt) {
	with (field) {
		if (value==null||value=="") {
			alert(alerttxt);
			return false;
		}
		else {
			return true;
		}
	}
}

function validate_email(field,alerttxt) {
	with (field) {
		apos=value.indexOf("@")
		dotpos=value.lastIndexOf(".")
		if (apos<1||dotpos-apos<2) {
			alert(alerttxt);
			return false;
		} else {
			return true;
		}
	}
}

function validate_form(thisform) {
	with (thisform) {
		if (validate_required(name,"Please specify your name!")==false) {
			name.focus();
			return false;
		}
		if (validate_required(sender,"Please specify the receivers name!")==false) {
			sender.focus();
			return false;
		}
		if (validate_required(email,"Email must be filled out!")==false) {
			email.focus();
			return false;
		}
		if (validate_email(email,"Not a valid e-mail address!")==false) {
			email.focus();
			return false;
		}
	}
}
</script>

When I run it on my server, I get the form and enter nothing into it, I just click submit. However, it goes straight to the php file and brings up my flash movie, which it shouldnt do. When nothing is entered, the js file should return the error. I thought I had everything set up correctly, but obviously not. Can someone see where I am going wrong?

cheers

for some reason this is not working can anyone tell me why?

Hi,

validation for pin must not be allow given below conditions

6 rising consecutive numbers(e.g 123456,456789 etc)
6 Descending consecutive numbers (eg. 654321,987654)
All same digit (eg 111111,222222)
Same digit appearing 3 or more time in pin code (eg:121212,1111432)

I have a validation issue. I need the input fields to highlight yellow if no text has been entered and when the form is submitted the error message displays to check the highlighted fields.
I get the input boxes to highlight when there is no text but on submit the form goes to the next page without the error alert message.
Any suggestions would be appreciated.

Hello Everyone

I am new on java script and I want to check the form blank text fields by using onChange event.

THANK YOU

Hi Folks,

I'm new here, as well as to JavaScript, and am stuck. I'm trying to get something to validate using the W3C file validation, and I'm stuck. This is XHTML 1.0 Strick, and I know that isn't JS, but since the error involved JS I posted it here. If I would be better putting it in HTML please let me know. Everything works fine on the page, but I keep getting one single error. The > in Red is what shows up as the issue. Do ya'll see something glaringly obvious that I did wrong?

Thanks for the help!


Code:

document.write("<a href='mailto:" + emLink + "' > ");

hi friends,

I have a question with me is javascript is the effective one to do validation?
And how it can be used for validation purposes..
