JavaScript - Seeting A Variable In Javascript?

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!!

Hi,

I am trying to write some code (not my main function in my job) to have a variable be inserted in the middle of a "<a href>" tag.

I created an XML file and I am parsing it with XSL and that is working well. In my XSL code I have the following (and it is working):

Code:

<xsl:for-each select="documents/data[frequency='Daily']">
<script>var meetingIndicator = <xsl:value-of select="meetingIndicator"/>;
</script>
<tr>
<td class="tableLink"><a href="" onMouseover="showmenu(event,linkset[0], '450px')" onMouseout="delayhidemenu()"><xsl:value-of select="meetingCategory"/></a><script>document.write(meetingIndicator);</script>
</td>
<td><xsl:value-of select="meetingCategory"/></td>
<td> 
<xsl:value-of select="duration"/> 
</td>
<td> 
<xsl:value-of select="purpose"/> 
</td>
<td> 
<xsl:value-of select="idealFor"/>
</td>
<td> 
<xsl:value-of select="instructions"/>
</td>
<td class="tableLink">
<a><xsl:attribute name="href">
<xsl:value-of select="documentURL"/></xsl:attribute>
<xsl:value-of select="supportingDocuments"/></a>
</td>
</tr> 
</xsl:for-each> 
</table>

In this part of the code:
Code:

<td class="tableLink"><a href="" onMouseover="showmenu(event,linkset[0], '450px')" onMouseout="delayhidemenu()"><xsl:value-of select="meetingCategory"/></a><script>document.write(meetingIndicator);</script>

I want to replace the 0 in (event,linkset[0], '450px') with the "meetingIndicator" variable (or even the "<xsl:value-of select="meetingIndicator"/>;") but I don't know how to.

I can call the "<xsl:value-of select="meetingIndicator"/>;" and it displays the correct value from the XML file. i just need to know how to place that in the "event,linkset[0]" part of the "a href" tag.

I guess it is going to be pretty easy but I have been googling and playing it since yesterday and i am not having any luck.

Thank you.

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!

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.

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 have used php with forms but can I do easy form to java vars? I saw one snippit of code that did it when I was newer but did not understand it.

what is the way you usually do this?

Hi:
I got a blank page returned when using javascript within the Frameset. Here is part of my codes:

(my javascript part)

<script language="JavaScript">
//this function will be used to get the parameter from URL using javascript
function gup (name)
{
name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
var regexS = "[\\?&]"+name+"=([^&#]*)";
var regex = new RegExp( regexS );
var results = regex.exec( window.location.href );
if( results == null )
return "";
else
return results[1];
}

//get the transactionID from the URL
var transactionID = gup('name');


//add the transactionID as the URL parameter
var url = "../../onetwothree/Approve.jsp?name=" + transactionID + '\"';

var temp = '<frame name=\"onetwothree\" ' + 'src=\"' + url + '>' + '</frameset>';

</script>

----------------------------

(my html part)
<frameset rows="0,*" border="0" frameborder="0" framespacing="0">

<frame name="onetwothreeFrame" src="../onetwothree/abcd.html" marginwidth="0" marginheight="0" scrolling="no" noresize>

<script language="JavaScript">
document.write(temp);
</script>
</frameset>

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
