JavaScript - Javascript Resizing And Reorganising Script?

Hello all,

I'm new to PHP (and web development in general) and have come across something that to me seems really, really bizarre!

Background

I am currently designing and developing an online enrolment form for my employer, a training company. The form consists of 3 pages - pages 1 and 2 are for data input whilst page 3 is a summary page with only one input, a box to check that the customer agrees to our T&Cs. Page 3 also includes a box where calculations are made as to the price of the selected training course based on choices made earlier in the form.

The form displayed on page 2, and some of the text on page 3, changes depending on a choice made on page one - that is, whether they are paying for the course themselves or their employer is funding it. If they choose employer, they get one form, if they choose self funding they get a different one. However, both of these forms are contained within a single .php file, using session variables to decide which one should be displayed.

I am using sessions to transfer the data between the pages. Each page has been made sticky using session variables. Real-time validation is carried out using javascript on each individual page, then a final PHP validation check is run on the whole thing when the customer tries to submit the final page. Javascript is also used on page one to calculate the price of the course in real time so the customer can see how much he/she will be paying before proceeding further.

The Problem

I find this really strange:
In Firefox, everything works perfectly In Internet Explorer, when JavaScript is turned off, everything is fine. But when JS is switched on, the PHP validation on the final page seems to go haywire, thus making it impossible to submit the form. In Chrome, again when JS is switched off, everything works, but when switched on, I can't even get past the first page. Instead of loading the correct form for page 2, I just get a blank screen.
Can anyone help? This is my first major project and I've been working on it for weeks, coming up against all sorts of problems and tearing my hair out but managing to solve them. Now I'm completely stumped, when I'm almost within touching distance of completion!!

I can't post the code here as it's 3 separate documents and very complicated, but if you want to have a look at the form itself go to:

I hope someone can help! Thanks very much!

All the best

I have a Perl script that contains a variety of inputs including a HTML <SELECT> and RADIO buttons. I would like to alter the presentation of a RADIO button choice with a DISABLED, based upon the earlier selection of from a <SELECT> drop down menu.

In Perl I attempted to capture the selection from the <SELECT> and use that value in a IF ELSE block, but this does not work. I have been told that this can be done with a Javascript.

I did a little bit of coding with Javascript around five years ago, so I am a rusty newbie. Can anyone give me a hand on how this should be constructed? The more detailed your examples or suggestions can be the easier it will be for me to grasp the solution.

Hi,

I am trying to add one image in footer of my application.

Code:
<div class="rightLinks">
<a href="#"><script src=https://seal.somesign.com/getseal?host_name=www.validsite.com&size=S&use_flash=NO&use_transparent=NO&lang=en></script></a>
</div>

But this is not working. Please let me know, what is wrong in it. And how can we correct it.

Thanks!!

I have an age script running in the attachment below. It works fine for numbers such as 1 22 1980.

Code:

if ((input.search(/\b([1-9]|[12][0-9]|3[01])\b/)!= -1) && (input.search(/\b([1-9]|1[0-2])\b/)!=-1) && (input.search(/\b(19[0-9]{2}|200[0-9]|201[01])\b/)!= -1)) {       
function getBirth() {   
    var now = new Date(); 
    var myMatchy = input.match(/\b(19[0-9]{2}|200[0-9]|201[01])\b/);
    var myMatchm = input.match(/\b([1-9]|1[0-2])\b/)
    var myMatchd = input.match(/\b([1-9]|[12][0-9]|3[01])\b/);
    var year = myMatchy[0]; 
    var month = myMatchm[0];
    var day = myMatchd[0]; 
    var today = 
	{ 
		"year" : now.getFullYear(), 
		"month": now.getMonth()+1, 
		"day"  : now.getDate() 
	} 

    var age = today["year"] - year; 

    if (month > today["month"]) 
        age--; 
    else if (month == today["month"]) 
	         if (day > today["day"]) age--
    return age; 
} 
document.result.result.value = "Your age is "+getBirth()+"."; 
return true;}

However, if someone writes out the month it doesn't. Such as January 22 1980. I did a work-around by inserting the month value. Highlighted below. But that means I would have to duplicate this lengthy code 12 times for each month of the year. Anybody know a better way to handle this? You can test it in the small attachment below. Any help would be appreciated.

Code:

if ((input.search(/\b([1-9]|[12][0-9]|3[01])\b/)!= -1) && (input.search(/(january)/)!= -1) && (input.search(/\b(19[0-9]{2}|200[0-9]|201[01])\b/)!= -1)) {       
function getJan() {   
    var now = new Date(); 
    var myMatchy = input.match(/\b(19[0-9]{2}|200[0-9]|201[01])\b/);
    var myMatchd = input.match(/\b([1-9]|[12][0-9]|3[01])\b/);
     var month = 0;     
    var year = myMatchy[0]; 
    var day = myMatchd[0]; 
    var today = 
	{ 
		"year" : now.getFullYear(), 
		"month": now.getMonth()+1, 
		"day"  : now.getDate() 
	} 

    var age = today["year"] - year; 

    if (month > today["month"]) 
        age--; 
    else if (month == today["month"]) 
	         if (day > today["day"]) age--
    return age; 
} 
document.result.result.value = "Your age is "+getJan()+"."; 
return true;}

I embedded the following into my blog;

Code:

<br><script language="javascript" src="http://www.quotedb.com/quote/quote.php?action=random_quote&=&=&"></script>
<br>

It works fine, but I'm trying to find a way to refresh only the script on my blog, instead of having to reload the entire page. Coding a refresh button, for instance. How would I go about doing this?

Thank you in advance.

Hi peeps

I found this script on another forum, It is nearly perfect, I was wondering if you peeps could help me make a few changes...

how do I change the cut off to 8pm I have tried

var c_t = 8; but it does 8am

I have also tried

var c_t = 20; but it doesnt work...

Any ideas?

Also instead of just saying "your order will ship shifted to tommrow" would it be possible to insert tomorrows date, i.e Thursday 13th
and then for "and your order will ship to Monday" could it say Monday 15th etc

Here is the script,

Code:

<html>

<head>

<script type="text/javascript">
function ord()
{
var c_t = 4;

var dd = new Date();

var ti_h = dd.getHours();

var ti_m = dd.getMinutes();


if(ti_h > c_t)
{

var di_t_h = ti_h - c_t;

var di_t_mi = 60 - ti_m;

var h = 24 - di_t_h;

var mi = di_t_mi;

var mess = h+"hours"+mi+"minutes";

}



var da = dd.getDay();

//var da = document.getElementById("da").value;

switch(da)
{
case 2:
case 3:
case 4:
case 5:
document.write("Place your order within the next 1 day"+mess+"and your order will ship shifted to tommrow");
break;
case 6:
case 7:
case 1:
document.write("and your order will ship to Monday");
break;
}
}

ord();

</script>

</head>

<body>

</body>

</html>

Hi,

I have a little problem with placing a javascript into a php script

If the action "Change" is true then I want to open a new window with a javascript below. I get an error message:
Parse error: syntax error, unexpected '<' in /home/........ on line xx
On that xx line starts the Javascript

What must I do to solve this problem.

<?php....................

if($_REQUEST['action']=="Change")
{
mysql_query("UPDATE Persons SET Itemstate = '{$_REQUEST['Nr']};' WHERE Nr={$_REQUEST['Nr']};");


<SCRIPT LANGUAGE="javascript">
<!--
window.open ('Examplepage.html')
-->
</SCRIPT>

........
?>

Hello, I need help again :3
Heres what I need: I need some javascript to random a script. Simply like this:
The script randoms a number
Based on the number it runs some lines of PHP script.

Random 1-10
If 1
Then run this PHP script
*PHP script*
*PHP script*
*PHP script*
*PHP script*
If 2
Then run this PHP script
*Different PHP script*
*Different PHP script*
*Different PHP script*
*Different PHP script*
If 3
Then run this PHP Script
*some more different PHP Script*
*some more different PHP Script*
*some more different PHP Script*
*some more different PHP Script*
If 4 etc etc etc

Each bit of PHP Will be similar, but be different in some ways. There may be more compressed ways of doing this. But if it at all possible, I would like it in the way I wrote it above. For instance I dont want:

Random 1-3
If 1 Run function 1
If 2 Run function 2
If 3 Run function 3
Function 3
*PHP Script*
*PHP Script*
*PHP Script*
Function 1
*PHP Script*
*PHP Script*
*PHP Script*
Function 2
*PHP Script*
*PHP Script*
*PHP Script*

I will thank the best answer! This website is awesome and has answered so many of my questions! Thanks in advance!

nevermind i figured it out myself

I have a webpage in which my users complete a form in order to get through to page 2. I cannot use PHP to check as it must be on-the-fly checking.

My idea was like the following:

PHP Code:
<script type="text/javascript">
function check(x)
{
    if (x == 1)
    {
        document.write('<IMG SRC="img/'+x+'.jpg">');
    }
    if (x == 2)
    {
        document.write('<IMG SRC="img/'+x+'.jpg">');
    }
    if (x == 3)
    {
        document.write('<IMG SRC="img/'+x+'.jpg">');
    }
    if (x == 4)
    {
        document.write('<IMG SRC="img/'+x+'.jpg">');
    }
}
</script> 


And for the images to actually be PHP files that check further details of the user and insert details to DB. Then when the user clicks the next button it will check to see if all 4 users have loaded under that users details.

However, I would much prefer it if I could use more PHP as I'm a Javascript n00b. Preferably I would like to use PHP to create unique keys for the images so that once I have obfuscated the javascript code the user will not figure out how to cheat the system even if they manage to reverse engineer the code.

Is it possible to use PHP within javascript?

E.g.
PHP Code:
<?php 
$pic = "picture.jpg";
?>
<script>
function something(){
document.write('<IMG SRC="img/$pic">');
}
</script>


Or is this not at all possible?

Edit: I know how much simpler that first script could have been, was just trying to simplify from my double as messy full script which will probably confuse you even more!!!

Hi,

Im new to javascript. I want to add a similar function on my blog like on http://techcrunch.com/2011/08/04/gro...tartup-obtiva/ when you press on author. It is a drop down made with javascript. Anybody can help with a similar javascript as I was trying different implementations for the whole night with no luck.

Maybe, anybody know a similar javascript online which I could modify?

Thanks in advance!

Is there a way to use inline javascript that will prevent any javascript after it (in the same page) from executing?

So, for instance I could have something like:

-Content-
-JS A-
-Content-
-JS B-
-JS C-

'JS A' would execute, 'JS B' would be the code I'm asking about and it would cause 'JS C' to not do anything.

Sorry if this is an off-the-wall question. I good with C/C++, VB, Ruby, Lua, HTML, etc, but I haven't gotten to Javascript (or Java) yet so I have no idea what the capabilities or environment setup are like.

Thanks in advance for any advice.

I am really new to JavaScript, and was following a tutorial that was using everything inline (probaby as its less confusing for the noob). Now I want to split it off into a script area, like my CSS has been.

I have:
Code:

<SPAN onclick="document.getElementById('glance').style.display='block';document.getElementById('front').style.display='none';">

Is something like this valid (this is a guess BTW)?
Code:

<SCRIPT type="text/javascript">

	function getElementById('glance') {

		.style.display='block';
		}

	function getElementById('front') {
		.style.display='none';
		}
</SCRIPT>
<SPAN onclick="document.getElementById('glance'); document.getElementById('front')"> ... </SPAN>

... or should function be document in the script area and document not be present in the SPAN attribute?

... Better yet, is there a way to put both the 'glance' and 'front' together like this:
Code:

<SCRIPT type="text/javascript">
	function getElementById ('glance') {
		.style.display='block';
		getElementById ('front') { 
			.style.display='none';
		}
	}
</SCRIPT>
