JavaScript - Javascript And Session Variable

I have been looking all over the web for a solution, because my website displays funky in safari. To fix this i figured i'd tell users that if they are using safari, then using javascript, i could tell them a message. Originally i tried detecting safari then displaying a message. But i couldn't ever find a browser detection for safari. So i thought wait....
If i could:
1. get a javascript alert saying my message.
2. time that message alert frequency by a session, say 10 days? or even every browser session...

Then i could solve my problem. However i can't figure out any of this. So if anybody would be willing to help, i'd be very grateful.

I have a site where i switch between two images using some JavaScript. What I need is to be able to set a session variable or something so that if someone selects shading on or off it sticks to that for the rest of the session.

Any idea or even a point in the right direction. Do i need cookies or is there a simple way to do this

Hi,

I have a website where the user can navigate different categories by tab. The problem is, when they're on a tab other than the default one and they refresh the page or click to another page, it puts them back on the first tab. I know this can be solved by using a session cookie of some type, I just need some help on implementing it into my site.

http://www.thatswhyimbroke.com/ - so you can see what i'm talking about. If you look at the different tabs: Price High, price low, food & drink, etc. I want the user to be able to go to one of those, click to page 2 or refresh, and still be on that tab.

Any help would be much appreciated!

Can anyone tell me of how to take or assign a javascript variable into php.

Hi,

is it cool/possible to use a php variable inside the javascript ?
i have this hidden html form field
PHP Code:
<?php $unique = md5(uniqid()); ?>
<input type="hidden" name="unique" id="<?php echo $unique; ?>" value="" />

then i have this javascript
PHP Code:
var hiddenfield = document.getElementById('<?php echo $unique; ?>');
hiddenfield.value = new Date().getTime();

LOL it doesn't work, can somebody help me please ?

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!!

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 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!

Gonna be asking a few Q's about a quiz javascript i'm making. I'm pretty new to JS.


I have this, a select box, in the body.

Code:

<div align="center"><center><p><strong>Your response:</strong> <select
          name="theresponse" size="1" onChange="responses()">
            <option value="-----">----</option>
            <option value="a">a</option>
            <option value="b">b</option>
            <option value="c">c</option>
            <option value="d">d</option>
          </select>

Then the relevant bit of script lower down

Code:

var loop=0
function responses(){
loop++
var temp2=document.instantquiz.theresponse
var temp3=temp2.options[temp2.selectedIndex].text
if (temp3!=solution[whichone]&&temp2.selectedIndex!=0)
document.instantquiz.thesolution.value="Sorry, the correct answer is "+solution[whichone];
else if(temp2.selectedIndex!=0)
document.instantquiz.thesolution.value=compliments[whichone];
}

I want to add 1 to 'loop' (so that people can't score twice etc.). The problem I have here is that loop just doesn't want to go up. I've tried all sorts of things like doing it under a new variable, and even putting a new function up, all in vain.

Why doesn't it work? =s

so i have this code i am working on(this is a dumbed down version of it)
Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html> 
    <head>
    

  <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(function(){
            $("#Submit").click(function(){
			for (i=0;i<=50;i++)
			{
                $.ajax({
                    url:"process.php",
                    type:"get",
                    data:$("form").serialize(),
                    success:function(response){
                        var obj = jQuery.parseJSON( response );
                        var success = obj.success;
                        var actionsNumber = obj.number;
                        $("#result").html('There have been  '+actionsNumber+'  loops completed');    
				

                    }
                })
            }
			
			})
        })
    </script>
    </head>
  <body>
    <form action="" method="post">
    <p>
    <label><strong>Number of Loops</label>
    </p>
   <input name="count" type="text" value = "1"/>
    </p>
    
    <p>
    <input id="Submit" type = "button" value = "Send">
    </p>
    </form>
    <p id="result">There have been 0 loops completed</p>
    </body></html>

so you see this for loop

for (i=0;i<=50;i++)

I want it to be able to be like

for (i=0;i<=count;i++)

so that it will loop the number of times inputted

also(though i dont know if this is something that i need to use js for) On my full code there are other textboxes that need to be sent to process.php each time that it is run.


How can i achieve this?


also before anyone asks i have googled this and searched around yet i havent been able to figure this out, everything i have tried hasnt worked

and here is the process.php

PHP Code:
<?php session_start();
// process the form data here
//:::::::::
//
if(!isset($_SESSION['number'])){
      $_SESSION['number'] = 0;
    }
$number =  $_SESSION['number']++;

// output json response 
echo'{"success":"true","number":"'.$number.'"}';
?>

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");
}

Hi,

I have a small script that opens a small popup in which to populate a form. What I want to do is include a variable so that a particular PHP page opens. I include where I am at present:

HTML page calling JS popup:
<input type="text" name="DOCUMENTS" id="DOCUMENTS" onclick="makeSelection(this.form, 'DOCUMENTS');">

JS Code:
targetElement = null;
function makeSelection(myform, id) {
if(!myform || !id)
return;
targetElement = myform.elements[id];
var handle = window.open("../file_upload.php?dir=CODE",
"mywindow","menubar=0,resizable=0,width=400,height=250");
}

What I want to be able to do is get it so that the bit of JS that has 'dir=CODE' has a variable called from the HTML page. Is this possible, and if so, could anyone please help me out?

Regards,
Neil

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!
