JavaScript - Decoding Javascript File

Hi,

I have the following code snippet:
test.html
======
<script language="javascript" type="text/javascript">
var testVariable = "test";
</script>
<script language="javascript" type="text/javascript" src="test.js">
</script>

test.js
=====
var testVariable = window.top.testVariable;

In firefox, I'm able to access testvariable defined within test.html in test.js.

But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html.

Can any one please let me know how i can make it work in chrome?. Am i missing something here?.

Dear All

I have a .js file in which i have pasted Urdu text and HTML tags like

function urdutext()
{

innerHTML.right_column='HTML tags & urdu text';}

The .js file contains about eighty lines of urdu text and some HTML tags in betweeen.

But when i run this file alone in my browser it displays half of the file and the rest of the lines remain undisplayed.

and when i use this file in my web page and when i click a button to display the urdu text, it dispays nothing in my web page.

I know the reason but i cant solve it my self.

The reason is that the .js file does not get fully uploaded and hence the file remains open and the syntax become wrong. And that is the reason it does not display anything in the web page.

So i want ut help. Any one can help and would take my best wishes.

Im coding a chat system, but the main thing which I cannot get working which is stopping me from doing this is displaying the data from the database.

I have made a test XML document for the time being so that I can get the JavaScript/AJAX working properly, then I will figure out why my PHP isnt generating the XML file properly.

Here is my XML document:
Code:

<?xml version="1.0" ?>
<root>
	<message id="0">
	<sender>martynball</sender>
	<receiver>someoneelse</receiver>
	<time>154375342</time>
	<text>Testing an XML document and seeing if the JavaScript will display it properly. 
	If so then there is a problem with the PHP.</text>
	</message>
</root>

And here is my JavaScript/AJAX, for some reason there is NOTHING being displayed in the div which has the correct ID.
Code:

<script type="text/javascript">
function getXmlHttpRequestObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}
//Make variables for later use
var lastMess = 0;
var sendReq = getXmlHttpRequestObject();
var receiveReq = getXmlHttpRequestObject();
var mTimer;

function getMessage() {
	if (receiveReq.readyState == 4 || receiveReq.readyState == 0) {
		//var url = "scripts/get_data.php?uid=<?=$_SESSION['uid']?>&m=" + lastMess + "&chat=1";
		var url = "testXMLdoc.xml";
		receiveReq.open("GET", url, true);
		receiveReq.onreadystatechange = manageMessage;
		receiveReq.send(null);
		lastMess++;
	}
}
function manageMessage() {
	if (receiveReq.readyState == 4) {
		var xmldoc = receiveReq.responseText;
		var chat_div = document.getElementById('chat');
		var msg_nodes = xmldoc.getElementByTagName("message");
		var n_msg = message_nodes.length;
		for (i = 0; i < n_msg; i++) {
			var sender_node = msg_node[i].getElementByTagName["sender"];
			var receiver_node = msg_node[i].getElementByTagName["receiver"];
			var time_node = msg_node[i].getElementByTagName["time"];
			var text_node = msg_node[i].getElementByTagName["text"];
			chat_div.innerHTML = "He  <br />" + sender_node[0].firstChild.nodeValue + "<br />";
			chat_div.innerHTML = reciever_node[0].firstChild.nodeValue + "<br />";
			chat_div.innerHTML =time_node[0].firstChild.nodeValue + "<br />";
			chat_div.innerHTML = text_node[0].firstChild.nodeValue + "<br />";
		}
	}
}
</script>

Also, I put a alert under the manageMessage() function before the IF statement and that gets displayed.

Hello, I am building a web application that has quotes on it. I am planning on having all the quotes stored in a .txt file. A line space would separate the quotes.
Example:
"Blah Blah"

"Idk what blah"

"sure you do"

Would this be using Javascript to pull the quotes from the txt file for use in my page be best? I need it to pull all the quotes. Reason for having it like this, I am also planning on having a random quote page where it just pulls 1 quote instead of showing all of them.

I'm also open to other ideas here!

I want to make an rpg with a username and password login without a database,
I was thinking, maybe i could make it when the user presses "sign up" the webpage creates a new file in the same directory that stores all their information. I researched it and realised it wasn't cross browser compatible. Therefore I came up with an idea to store all the users' information in a array.

What i want to do is that when the user presses "sign up" it adds that user to the array and the html file overwrites itself so the new user is saved into the array

Any ideas?

        var absPath = getPath();
        var file = mfObj.CreateTextFile(absPath + filename, true);
        file.Write(outputXML);
        file.Close();
    }

        function getPath() {
        var path = document.location;
        var str = new String(path);
        var end = str.lastIndexOf("/");

Hi guys i have an embedded game in an html (unity3D) and i am wanting to delete a file from my server.

so at the moment i have a php file on my server and the html containing the javascript on my desktop.

test.php
PHP Code:
<?php
$conn = ftp_connect("ftp.domain.co.uk") or die("Could not connect");
ftp_login($conn,"username","password");

echo ftp_delete($conn,"test.txt");

ftp_close($conn);
?>

I will out the correct domian name and username and password and this should delete a file named test.txt on my server.

the problem i am having is calling this script from my javascript which is my main html:
i have searched all over and found if i do this :
Code:

<script language="JavaScript">
        function DELETE_SERVER_FILE()
        {
                dummyimage = new Image();
                dummyimage.src ="http://www.domain.co.uk/test.php"
        }

</script>

But this is not working, can anyone help?

Hello, I am looking for a way to tell from javascript if a file exists (on the server). I don't mind doing this with a .php script, if I have to, but the javascript still needs to know if the file exists.

I thought the following javascript code might work:

Code:

var file_exists = <?php echo file_exists("OpenTokSessionId.txt"); ?>;

but it didn't. PHP parsed the php code, but it didn't assign the result value to the Javascript variable like its supposed to (or at least, it didn't seem to). When I looked at the page source after I uploaded it to the server, that line of code now looked like this:

Code:

var file_exists = ;

Note that my server is setup to pass files with an .html or .htm extension to the php engine. That is why this kind of stuff can be done. But for some reason, php doesn't seem to be able to output bool values. I tried the following .php script, which I loaded directly in my browser, but it didn't output anything:

PHP Code:
<?php
  function fileExists() {
      return file_exists("OpenTokSessionId.txt"))
  }

  echo fileExists();
?>

So I changed it to the following, and it outputted "File does not exist.", which is the expected result:

PHP Code:
<?php
  function fileExists() {
      if (file_exists("OpenTokSessionId.txt"))
             echo "File exists.";
      else
         echo "File does not exist.";
  }

  fileExists();
?>

Ok, I am currently working on an announcements portlet for a dashboard that my team is creating. What is desired is to be able to have this portlet access a stored text file (file can be edited so content is subject to change) that will have all the information needed for these announcements. The JavaScript will then write it into a html file.

I am a novice at html, and javascript; and i was hoping that if anyone had any advice, ideas, or a helpful link that could point me in the right direction I would much appreciate it.

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.

Hello all, I am new to javascript and I have run into a problem. I cant seem to be able to write to a text file called users.txt

Here is my code:

Code:

<html>
<head>
<script language="javascript">


function rf()
{

    var fs,file;

    fs = new ActiveXObject('Scripting.FileSystemObject');

    file = fs.OpenTextFile('C:/Users/Imran/Documents/Imran          IT/Web/Test/user.txt',2);

    file.Write('The text to write to file');

    file.Close();

}
</script>
</head>
<body onLoad="rf();">

</body>
</html>

What I do is I put the code in notepad, I then save it as a .html file and try run it in IE 7, google chrome and firefox, Each time users.txt is unchanged.

Any help appreciated.

All I want is for the client to send a variable to the server and for that variable to be saved in a .txt file.

If there is another way to do that, please share

Is it possible to self source a javascript file?
I have a file with code that opens a javascript window and document.writes
to it. I want to run some code in this file attached to window.onload.

Code:

function someWindow()
{
var openedWindow = open(/* relevant vars */);
openedWindow.document.write(/*doctype and html head markup*/)
openedWindow.document.write("<script type=\"text/javascript\" src=\"(this file)\"></script>");
openedWindow.document.write("<script type=\"text/javascript\">window.onload = function(){ /* sourced code */}</script>")
openedWindow.document.write(/*html body markup*/)
openedWindow.document.close();
}

then in the same file have code defining object constructors and such that
attach events to various elements.

I realize I can write a long string variable with all the code, but that would
be visible a browser window -> view source window ( I know it won't hide
the code in a separate source file)

The object is to have a widget all in one file, rather than having a separate html, css file and another javascript code file.

Thanks for advice, suggestions, encouragement,
JK

I'm trying to include an HTML/CSS Navigation Bar in a JavaScript file for easy editing (instead of going from page to page changing the same thing).

This is the HTML & CSS I want to include in the JavaScript file:
<a style="border-left: 1px solid white; padding: 5px" class=menu href="Index.html" title="Home">&nbsp;Home</a><a class=menu href="menu1.html" title="Portfolio">&nbsp;Portfolio</a><a class=menu href="menu2.html" title="About Us">&nbsp;About Us</a><a class=menu href="menu3.html" title="Media">&nbsp;Media</a><a class=menu href="menu4.html" title="Store">&nbsp;Store</a><a class=menu href="menu5.html" title="Contact Us">&nbsp;Contact Us</a>

-If this isn't possible to do in JavaScript, then what language can I do it in?
