JavaScript - Is There Any Way To Re-retrieve That Javascript File, From The Server
So, this is my last problem. If I can nail this, then the website will be completely AJAX driven, and will be spectacular.
It took me a while to figure out just how to ask the question. lol Now it is really simple. 1) When I hit the button, in the simplified example below, the website sends a code to the server. 2) The server then re-writes the "xyz.js" JavaScript file with a new array of values. Is there any way to re-retrieve that JavaScript file, from the server to make it the current "xyz.js" rather than the old one that loaded on the client originally. I can get a new XML data file and re-submit that to the website, but how do I re-retrieve the new JavaScript code? Code: <html> <head> <script src="xyz.js" type="text/javascript"></script> </head> <body> <button onclick="onload();">Change</button> </body> </html> Similar TutorialsI'm attempting to pull the hidden iframe file upload trick using javascript. I've go my form file upload and iframe fine, but I can't figure out what to do when it gets server side. There seems to be relatively no documentation on how to handle uploaded files in server-side javascript. Ideas? I'm at a loss.
I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page. The script works fine when the requested XML file is stored on the same server as the script. The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers? Thanks in advance for any help. Javascript Code Code: window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;
document.getElementById("makeXMLRequest").onclick = getNewFile;
}
function getNewFile() {
makeRequest(this.href);
return false;
}
function makeRequest(url) {
if (window.XMLHttpRequest) {
xhr = new XMLHttpRequest();
}
else {
if (window.ActiveXObject) {
try {
xhr = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) { }
}
}
if (xhr) {
xhr.onreadystatechange = showContents;
xhr.open("GET", url, true);
xhr.send(null);
}
else {
document.getElementById("updateArea").innerHTML = "Sorry, but I couldn't create an XMLHttpRequest";
}
}
function showContents() {
if (xhr.readyState == 4) {
if (xhr.status == 200) {
if (xhr.responseXML && xhr.responseXML.contentType=="text/xml") {
var outMsg = xhr.responseXML.getElementsByTagName("choices")[0].textContent;
}
else {
var outMsg = xhr.responseText;
}
}
else {
var outMsg = "There was a problem with the request " + xhr.status;
}
document.getElementById("updateArea").innerHTML = outMsg;
}
}

Here is what i have. You can see how it works (and doesn't) here http://www.brittv.co.uk/template.php...ws.stream_360p Code: <html>
<head>
<title>...</title>
<?php
$URL_GETKEY="http://www.uktvlive.com/tvc/key.php";
function doCurl($url)
{
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
$a=doCurl($URL_GETKEY);
$split=explode("<split>",$a);
?>
<script type="text/javascript">
// parse the querystring and create a dictionary of terms for later use:
var qs = [ ]; // where the dictionary goes
if ( location.search.length > 1 )
{
var pairs = location.search.substring(1).split("&");
for ( var p = 0; p < pairs.length; ++p )
{
var pair = pairs[p].split("=");
qs[pair[0]] = unescape( pair[1] );
}
}
// do the replacements *after* page is loaded, for simplicity:
function doReplacements( )
{
var link = document.getElementById("link1");
link.href = "rtsp://81.104.67.230/"+ qs["host"] + "/" + qs["stream"] + "?userID=" + "<?php echo $split[5];?>" + "&accessKey=" + "<?php echo $split[6];?>" + "&sdp=alt&device=mobile";
link.innerHTML = qs["page"];
// and of course you could do any other replacements, too.
}
window.onload = doReplacements;
</script>
</head>
The following part produces the url Code: <body> <br/><br/> <a id="link1">Generic Link</a> <br/><br/> Lastly we have the player embed code, this is where im stuck im afraid Code: <script type="text/javascript">
var url = qs["link1"]; // or whatever name it was passed by
document.write('<OBJECT CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" '
+ ' WIDTH="300" HEIGHT="160" '
+ ' CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab">\n'
+ '<PARAM name="SRC" VALUE = "http://www.tvpc.com/images/image1.gif" >\n'
+ '<PARAM name="QTSRC" VALUE = "' + url +'" >\n'

Thanks in advance guys Let me give an example: javascript: var myvar=10; function myfunc(){}; void(0); After excuting the above js source code in the address bar of my browser, I can use window.myvar and window.myfunc() to access myvar and myfunc. This indicates that the above "address-bar javascript code" must have been stored somewhere in the current page. My question is: where is the "address-bar javascript code" stored in the current page? or equivalently, is it possible to retrieve the "address-bar javascript code" by using some other javascript codes? I checked document.childNodes and document.documentElement, but cannot find the javascript source code. Maybe the source code is stored in the window object? How to retrieve it? Thank you very much for the help! All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero Hi, I am trying to access an XML file from a server in my JavaScript code. I have an XML file like this: -<stream version="1.2"> -<room id="simulator" time="128168557915"> -<dimention id=0 x="1.25" y="2.00"> <m mcu="160" sid="75"> </dimention> </room> -<room id="simulator" time="128168557928"> -<dimention id=0 x="1.95" y="1.86"> <m mcu="160" sid="55"> </dimention> </room> </stream> this file is generated by an application and I can access it from a URL ( since I am using the simulator for this application the XML is accessible from http://localhost:8081/feed/demo) This xml file is updated every few seconds and constantly growing. I have a javascript code which I've added the following code to it in order to use the data from XML file: <script type="text/javascript"> if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","http://localhost:8081/feed/demo",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; document.write("<table border='1'>"); var x=xmlDoc.getElementsByTagName("room"); for (i=0;i<x.length;i++) { document.write("<tr><td>"); document.write(xmlDoc.getElementsByTagName("dimention")[i].getAttribute("x")); document.write("</td><td>"); } document.write("</table>"); </script> Now here comes my problem: if I have the XML file saved on same drive as html page and I address it like this: xmlhttp.open("GET","floor.xml",false); it works fine, but when I pass the URL it doesn't. is there anything else I should do in case of loading the xml from URL? my second question is that I want to use the text values returned by xmlDoc.getElementsByTagName("dimention")[i].getAttribute("x") in an if statement like this : if (valuereturned = 2.00) { do sth } what is the best way to do that, since the returned value is a text. I need the answer ASAP and I really appreciate your help, thanx :-) Dear friend , I am uploading text file on html page , that text file lies on desktop and getting updated at every hour . I will keep my html page on server so how will it upload that text file from my desktop ? it is being generated by one cloud sensor . I am wanting to setup a dependant drop down where when a user clicks on the first drop down, it changes the contents of the second. The way I intend to do this is via a csv file. I have found several scripts but I have been unable to get them to work. Two of which a http://answers.yahoo.com/question/in...3114347AA7GYJ7 http://purbayubudi.wordpress.com/200...ng-javascript/ The first is the better option from what I can see. but the problem is readyState seems to be always 1. I am wondering if someone could perhaps give me a few moments to see if I can get this to work or suggest a better solution. I don't want to use a database approach, at least not yet. well i'm kind of new to this website and scripting with javascript but i am wondering: in a client side .js file i have some coding which results in a string which is stored in a variable called exportData now i want that string to be written into a text file on a server but how do i do that? it is not local on the client's pc and i can't find how to do it anywhere... can you guys help me? greetings, Fady Hello, Is there a way using javascript to have it check if a file exists on the server? I'm trying to check for a file on my server without having to refresh the open webpage. If this can't be done with javascript, do you know which webpage languange can execute this? Thanks Hi there, Can anybody help me to write php/javascript code which will allow users to open files directly from web browser into desktop application? Here is the specification: I have a photo editing business with many people working in Photoshop. I am currently developing a web based application (joblist) using Javascript and PHP which should allow the photoshop designers to browse and open files/images directly from joblist/web browser into photoshop. The reason I want this instead of browsing folder is that I have a database where I store who worked on which file, when and how long it took. The concept is that, designers will select a file and click on start, as soon as they click on start the original file will open in Photoshop and there will be an entry into database (using PHP). Once they finish the task they will close the file and click on Finish button. My joblist application will be published in a local server and the file will be open on a local network, so when they save the file it will be saved where the source file is located in (local server). The application should work in both PC and Mac. I have already done all other part of the application except file opening directly from browser to desktop application functionality. Anybody can help me to write the code (PHP or Javascript) which can open the file from browser (local server) directly into desktop application e.g. PHotoshop or Illustrator? Thank you very much I look forward to someone's real help! Best regards Mr. Sumon Hi there, I have a photo editing business with many people working in Photoshop.

Here is the line of code I'm adding: Code: echo '<td><a class="link" href="#" onClick="ajaxwin=dhtmlwindow.open('ajaxbox', 'ajax', 'pages/post.php', 'Composing Mode: Post', 'width=650px,height=400px,left=300px,top=100px,resize=0,scrolling=1'); return false">Compose</a></td>';
It is not a php issue, I plaintext the link and it still did the same thing. I have trying to save an update the xml file which is there in same folder in which HTML page is there. In HTMl page i have written javascript code to Save and Update XML on server.The code is like this Code: function Save()
{
var xmlDoc= new ActiveXObject("MSXML.DOMDocument")
xmlDoc.async="false"
xmlDoc.load("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml")
//..code to modify xmlDoc
xmlDoc.save ("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml")
xmlDoc = null;
alert('Details saved');
}
When i am accessing HTMl page on server from client and this function is called error 'Parameter is incorrect' is showing on line Code: xmlDoc.save ("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml")
Note: xmlDoc.load("/show/Share%20Workspace/Nidhi/Share%20%Document/Account.xml") is working fine. The save is working fine in local but not when on server and request from client. Kindly suggest me the possible solution to it. Hello I am using PlainAjax. http://coolpenguin.net/plainajax/?p=examplespostdata Here is my code and it is not working if i called from Javascript function. Code: <script type="JavaScript" src="plainajax.js"></script>
<script language="JavaScript" >
function openWin()
{
.......
.......
.......
var selval = selectedValue.toString(); // Dynamic value variable
document.formlist.myval.value = selval; // stored to hidden variable
var cn = document.getElementById( "itsme" ).childNodes; // Get all the nodes
var myresult = new Array(); // declare result array
plainajax.request('respurl: req_php.php; resultloc: myresult; paramloc: cn;');
Window.open("req_php.php");
}
</script>
<html>
<div id="itsme">
<input type="hidden" name="myval" id="myval" value="">
</div>
</html>
req_php.php ========= Code: <?php echo "value from html = ".$_REQUEST['myval']."<br>"; ?> But i am not able to get any value in my php program. What i did wrong in this? or is anyother way to pass the variable from Javascript (except pass thru url query string, this is not secure) Thanks I would like to use functionality similar to DirectoryInfo and FileInfo using server-side javascript in ASP.NET, but neither are recognized. What are the equivalents, if they exist, in javascript?
