JavaScript - I Want To Download The Javascript Command List. Need To Learn Javascript On Screen.

Very naive coding question... i'm a novice coder and i think javascript is the solution i need but - maybe there's better ways...

Ok - my website accepts a login password to access certain pages.
Depending on the password entered i set a javascript variable to either 'true' or 'false'.
If the variable is set to 'true' then i want to give the user access to shopping cart buttons, if 'false' then the shopping cart buttons should be hidden.

My current solution is to wrap javascript around each shopping cart button and display only if the variable is set to 'true'.

The shopping cart button looks a bit like this:
Code:

<form method="post" action="http://www.shoppingcart.com">
<input type="hidden" name="product" value="product" />
<input type="hidden" name="price" 	value="9.99" />
<input type="hidden" name="return" value="http://www.home.com"/>
<input type="submit" value="add to basket" />
</form>

I've tried displaying this using document.write() - but it gets confused when it encounters the ":" in the web address.
Also i get the impression from trawling the forums that document.write is not flavour of the month these days.

And another thought - I accept the variable on one page - then move to multiple other pages to reference it.... will the variable still be there when i move to other pages or do i need to somehow pass it across each time?

Trying to keep my coding XHTML compliant...

Any pointers and idiot proof suggestions would be much appreciated.

Dear all,

attached is a page for my website to allow visitors to purchase photos.

It is made from 2 Paypal example scripts - one for the form and another for an additional text box. It works fine apart from one detail, the text being entered does not get sent - instead, the information it forwards is
"6x4 Colour Prints. Item Number id10"

The "6x4 Colour prints" bit is good - the "Item number id10" is where I'd ideally like to see the custom text being entered and the guys at Paypal developer forums have said that a Javascript command is overriding the text being forwarded and to seek advice from those who know Javascript.

I've tried for a day by trial and error to see if I can take this command out but it has got to the hair pulling out stage so I'm calling on those who know best to cast a wise eye over the code and see if there is an easy fix to this.

Any help or suggestions as to howe to alter this will be most gratefully received.

Thanks in advance,
Dave.

Hi there,

On this website:

http://www.lutanho.net/stroke/online.html

it's allowed to "copy the games to your PC and play them offline".
That's nice but how do I do that?
I've tried to download/copy the game "WordGrid" to my PC but it didn't work.
Help would be appreciated.
Thanks in advance...........

Can anyone give me the code for the following:

Suppose there is a hyperlink for file downloading in a html document. If I click on the link a new pop up window will come up which will be in the form of a typical file download popup window and will ask me to either "open" or "save" or "cancel" or "more info" (just as it happens in a typical file download process where a file download popup is being thrown).

Also my file(the file can be in any format---.doc,.pdf,.exe or whatever)resides in my local hard drive and when I click on the hyper link the file download popup will comeup and will give me the 4 options as mentioned above.It wont just display the content of the file to be opened in new popup window.It will explicitly give the 4 options for any type of file to be downloaded thru the hyperlink.

This coding is to be done only and only with HTML and JAVASCRIPT .

Can anyone help me by providing code for the above task.

Hey guys I've a download page with a button 'DOWNLOAD NOW'. When the button is clicked visitors will have to wait for the download to starts (doesn't redirect).

What I want is that sometimes it takes very long for the DL to start after clicking the button, for instance 10 seconds. Hence I want to show a simple preloader WHEN the button is click, while waiting for the browser to stop loading and download to start, AND hide the preloader when browser stop loading and download started.

I have set javasscript code to detect and store into variable screen resolution.
How to store this javascript into variable PHP?



PHP Code:
<script type="text/javascript">
var ScreenWidth=screen.width; var ScreenHeight=screen.height; var ScreenResolution=ScreenWidth+"x"+ScreenHeight; document.write("<span style=\"color:red;text-transform: capitalize;\">your current screen resolution is " + ScreenResolution + "</span>");
--></script>
}
</script>

<?PHP
$screen=str_replace("#","",$resolution); echo "screen width is:".$screen;
?>

hi,
I have a website which is available on internet and uses lot of javascript code. Someone recently reported a bug and I fixed it in a javascript file. Now I want to move this updated js file on my server. but I am confused, how will this fix now be downloaded on every user's browser when they access website the next time? Is the download to client machine dependent on browser settings? could it be possible that some customer machine has latest file and some do not. How do I force file to download on client machine independent of client browser settings?
thank u

Hello all,
I want to screen scrape a citrix application using server side java script.
Currently I am making use of WScript.Shell ActiveXObject and try the following :

var objShell =new ActiveXObject("WScript.Shell");

objShell.AppActivate("Metaframe Presentation Server"); // this is the title of the citrix dialog that opens up once the application gets launched.

objShell.SendKeys ("{ENTER}")

Using AppActivate, the focus is transferred to the dialog mentioned above, but then the SendKeys do not work.
Do I need to do it differently?

Please provide your valuable help.

This is what I tried but alas, it does not work por que no?

This is located on my main index file which if the result of z is greater than 1, I would have the user stay at this page as opposed to redirecting to the portrait design. I have optimized the website for mobile use so there is a reason of having two different pages, the wide screen has extra tools / other stuff that isn't shown on the portrait not because of size/responsive design but becasue I want it to be this way. Anyway... "What's the situation captain?"

This is located above my <style> tag

Code:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script language="JavaScript" type="text/javascript">
<script>
function redirect() {
var x = screen.width;
var y = screen.height;
var z = x/y;
    if (z<1) {
    window.location.replace("alternate destination");
    };
    else ( ){
    // stay here
    };
};
</script>

You have extra semicolons in there. In general, don't put a semicolon directly after a right brace };

There are a couple of exceptions, but they don't apply here.

What's the point in having the else??

Hi All,

I am really stumped. I am not sure why it's not working.

Basically, selecting a country will pre-populate the state field for both billing and shipping sections. Please help!

Also, when copying the billing info from shipping, the state field doesn't seem to copy over.

I have attached the entire code as a text file (part1 + part2 = complete code).

Thanks!

I currently have a JavaScript function that works great except for what I am about to explain and wish that i can get it worked out by utilizing someones help in this forum. So, Here goes.

I have 2 list boxes one that has a list of options and one empty. when I click the button between the two It places the values into the other box and vice versa which currently works fine. The thing is when I click the submit button to store that info from the list box to the empty box in a DB it does not record the value's as if the box was empty after I have already selected from the list. is there anyone that can help me in figuring this thing out, I would greatly appreciate it.

Here is my code:


JavaScript

Code:

<script language="javascript">
					function validate_list()
						{
		   					if ( document.theForm.ToLB.value == "" )
		   				{
		       				alert ( "Please select header column from the list box. " );
		       				return false;
		   				}else
		
		   					return true;
						} 
					function move(tbFrom, tbTo) 
						{
							 var arrFrom = new Array(); var arrTo = new Array(); 
							 var arrLU = new Array();
							 var i;
							 for (i = 0; i < tbTo.options.length; i++) 
						 {
						  arrLU[tbTo.options[i].text] = tbTo.options[i].value;
						  arrTo[i] = tbTo.options[i].text;
						 }
							 var fLength = 0;
							 var tLength = arrTo.length;
							 for(i = 0; i < tbFrom.options.length; i++) 
						 {
						  arrLU[tbFrom.options[i].text] = tbFrom.options[i].value;
						  if (tbFrom.options[i].selected && tbFrom.options[i].value != "") 
						  {
						   arrTo[tLength] = tbFrom.options[i].text;
						   tLength++;
						  }
						  else 
						  {
						   arrFrom[fLength] = tbFrom.options[i].text;
						   fLength++;
						  }
						}
						
						tbFrom.length = 0;
						tbTo.length = 0;
						var ii;
						
						for(ii = 0; ii < arrFrom.length; ii++) 
						{
						  var no = new Option();
						  no.value = arrLU[arrFrom[ii]];
						  no.text = arrFrom[ii];
						  tbFrom[ii] = no;
						}
						
						for(ii = 0; ii < arrTo.length; ii++) 
						{
						 var no = new Option();
						 no.value = arrLU[arrTo[ii]];
						 no.text = arrTo[ii];
						 tbTo[ii] = no;
						}
						}
