I am trying to use a php variable in javascript.

At the moment I am using a fixed variable

PHP Code:
$articleID = 5; 


Then outputting it to the page to declare a javascript variable

Code:

var articleid = "<?php echo $articleID; ?>";

Then trying to us it within a string

"FlashVars", "fileURL=../uploadedfiles/+ articleid + .gpx&key=ABQIAAAAOQBC.........

Can anyone tell me what I am doing wrong? I am not very used to Javascript and perhaps I am going about it totally the wrong way.

Help!

Is it possible to pass the value of a javascript variable through src? For example, instead of...

<script type="text/javascript" src="/myfolder/myjsfile.js"></script>

...could I have something like...

<script type="text/javascript" src=JS VARIABLE VALUE></script>

What would be the syntax for this? Is it even possible?

Thank you!

I get the screen resolution with this script:

<SCRIPT language="JavaScript">
<!--
height = screen.height;
width = screen.width;
document.write(width + "x" + height);
var x = ( width + "x" + height);
//-->
</SCRIPT>

Now I have some links below and I want to use bold if the link has the same screen resolution:

<a href="page1">800x600</a>
<a href="page2">1024x768</a>
<a href="page3">1680x1050</a>
<a href="page4">1920x1200</a>

Supposing my screen resolution is 1920x1200, the result should be:

800x600
1024x768
1680x1050
1920x1200

How do I do that?

Thx!!

If I manually write out "2/22/2012 4:00 PM" in TargetDate, I get the correct result for what I want to do (a countdown). But I want the countdown to always be the current day at 4pm. So I tried the code below thats commented, but it is not working. New to javascript, still reading the books, just hoping for some guidance on this.


Code:

Next Update: <script language="JavaScript">
var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate()
var year = currentTime.getFullYear()
TargetDate = "2/22/2012 4:00 PM";
//TargetDate = "document.write(month + "/" + day + "/" + year) + 4:00PM";
BackColor = "white";
ForeColor = "red";
CountActive = true;
CountStepper = -1;
LeadingZero = true;
DisplayFormat = "%%H%% H, %%M%% M, %%S%% S";
FinishMessage = "Forecasts posted";
</script>
<script language="JavaScript" src="countdown.js"></script>

Hello everybody

I have a problem with Java Script damned
I want to add the values of several variables in one variable and then use this variable, which contains the values of variables

You can see the following example

HTML Code
PHP Code:
<input type="text" name="txt1" />
<br/>age 
<input type="text" name="txt2" />
<br/><br/>
<input type="button" name="submits" value="send"/> 


Javascript Code
PHP Code:
field = document.getElementsByName('txt1')[0];
field2 = document.getElementsByName('txt2')[0];
submit = document.getElementsByName('submits')[0];
data = 'data=' + field.value + '&data2=' + field2.value + '&submits=' + submit.value;
            
document.getElementsByName('submits')[0].onclick = function(){
    alert(data);
} 


After executing this code I find that the variables are not displayed values
As in the following picture


I want to know what the cause of this problem ?

This might be a stupid question, but is there any memory usage difference between var variable1, variable2; and var variable1; var variable2;? I'm learning how to use faster code hence the question.

Hi,

I am making a small software which will require activation.

My problem is when I activate my software after checking the key through my website I want to enter some information in registry of the user.

Now my problem is when I check the value through my website how can I return after verification to the local computer.

is it possible if I create a session variable or some other type of variable (not sure what type) and then read that variable on user computer. If that matches I will enter the code in registry.

I've been having a hard time with this and was hoping someone here would take a little pity and render me a great service.
I'm using a javascript to get the user's timezone and am trying to pass the response to an input field in a php form.
With a great deal of trial and error I got a demo working to a point but I'm stuck.
Here's what works now:
Code:

<p id="timezoneInformation" style="text-align: center;">click here</p>
<script src="jstz.js"></script>
<script>
var container = document.getElementById("timezoneInformation");
var showTimezone = function () {container.textContent = jstz.determine().name();};
container.addEventListener("click", showTimezone);
</script>

jstz.js is from Automatic timezone detection using JavaScript

The example above is as far as I've gotten. I would like to send the results to a form field to submit to the server.
It's probably a lot easier than I'm making it out, but I've had little success and would welcome any help.
Thank you.

I'm trying to echo a php variable to my javascript function but nothing is happening

Basically this php page displays bunch of records with a radio button next to each record. So when the radio button is clicked it would open that record in a new window that is clicked.

Code:

<input type='radio' name='option' value='$ctr' id='$ctr' onClick="edit_record('<?php echo $ctr ?>')">

<script type="text/javascript">
function edit_record(){
   var value = arguements[0];
   alert("record id: " + value);
   window.open("Edit.php", "Edit Record", "status=1, height=400, width=900, resizable=0");
}

So, I need to use a javascript variable when reading a value from a asp array. Currently I have a windows app that has a webbrowser. Teh windows app invokes a javascript method through the webbrowser and this javascript method returns an object. This object is built in the javascript function using values which exist inside a classic asp array. Phew! The function that sits on the relevant asp page, is invoked from my windows app and then returns the object to the windows app is below.

function item(count) {
var pid;
var description;
var fullprice;
var discountprice;
var quantity;
var size;

this.pid = '<%=SBagArray(0,count) %>'; //ProductId
this.description = "<%=SBagArray(1,count)%>"; //description
this.fullprice = <%=SBagArray(8,count) %>; //Fullprice
this.discountprice = <%=SBagArray(9,count) %>; //Discountprice
this.quantity = <%=SBagArray(6,count) %>; //Quantity
this.size = <%=SBagArray(2,count) %>; //Size

this.getPid = function() { return this.pid; }
this.getDescription = function() { return this.description; }
this.getFullprice = function() { return this.fullprice; }
this.getDiscountprice = function() { return this.discountprice; }
this.getQuantity = function() { return this.quantity; }
this.getSize = function() { return this.size; }

}

My problem is that the variable 'count' is not recognised by the asp. So, how can I use this variable in such a way that it works? This is driving me crazy!

Any help would be greatly appreciated!

Thanks!
