JavaScript - How To Connect To Tcp Port Using Javascript
Hi, I'm a newbie to javascript programming and I'm seeking on a solution on how to connect to a tcp port using javascript. Basically, we have phone server that is constantly streaming XML data on port 1024 (serverIP:1024). I've ran a packet sniffer and was able to gather the elements and attributes for the XML data that the server is streaming. Now, I have a test XML parser which works with the XML document using the elements and attributes i've gathered from the packet sniffer. Is there a way for me to connect to the TCP port i've mentioned using javascript and incorporate it with the XML parser that I have.
Here is the code for my XML Parser. Quote: <html> <body> <script type="text/javascript"> var xmlDoc; if (window.XMLHttpRequest) { xmlDoc=new window.XMLHttpRequest(); xmlDoc.open("GET","acddataentry.xml",false); xmlDoc.send(""); xmlDoc=xmlDoc.responseXML; } // IE 5 and IE 6 else if (ActiveXObject("Microsoft.XMLDOM")) { xmlDoc=new ActiveXObject("Microsoft.XMLDOM"); xmlDoc.async=false; xmlDoc.load("acddataentry.xml"); } document.write("<table border='1'>"); var x=xmlDoc.getElementsByTagName("ACD"); for (i=0;i<x.length;i++) { document.write("<tr><td>"); document.write(x[i].getElementsByTagName("Calls_Waiting")[0].childNodes[0].nodeValue); document.write("</td><td>"); document.write(x[i].getElementsByTagName("Crt_Wait_Time")[0].childNodes[0].nodeValue); document.write("</td></tr>"); } document.write("</table>"); </script> </body> </html> Any help on this is highly appreciated. Thank in advance. Similar TutorialsI have a Java Applet that I have been managing for some time. Approximately how long would it take to port a 900 line Java Applet to JavaScript? My intention is to reproduce as close as I can to the Java Applet. If you would like to see the Java Applet code, it is available here : http://www.chatapp.comuf.com/AppletClient(Public).java This Java Applet is a chat client that connects to a Java server (I am NOT porting the server). It has a simple interface with panel tabs for various activities (chat room, login, text color chooser, etc). **Note : I have not programmed in JavaScript before. I went over some tutorials before I posted this. ***N00b note : I know Java and JavaScript have NOTHING to do with each other. Hello there everyone, I've been stuck on this for about a day and a half. My code is for a connect four game in Javascript. The problem resides in the minimax recursion AI function. Code: function bestMove(color,depth,maxDepth)
{//Finsd the best move for the side. Returns column and score pair
//depth specifies current level of depth (should be passed as 0)
//maxDepth specifies the maximum depth to search
//holds the best score
var best = new Worth(-100000,0);
if(depth%2==1)best.Score*=-1;
var mv = new Worth(0,0);
for (i=0;i<7;i++)
{ //try putting a piece at each of 7 columns.
mv.Column=i;
if(height[i]==-1){
}else{
//find the row to put this piece.
gameB[height[i]][i]=color;
height[i]--;
alert(""+i+"");
//find if it is a game over, don't search further if it is
//a score of 100 or -100 means a game over
var cur = new Worth(0,0);
cur.Score=checkWin(height[i],i,color);
if(cur.Score==gold){
cur.Score=-100;
}
if(cur.Score==silver){
cur.Score=100;
}
if(cur.Score==100||cur.Score==-100||depth==maxDepth){
mv.Score=cur.Score;
}else{ //search further (this one is the recursive call
if(color==gold) {
color = silver;
}else{
color = gold;
}
mv.Score=bestMove(color,depth+1,maxDepth).Score;
}
//if this move is better, use it instead
if(mv.Score>best.Score&&depth%2==0)
best=mv;
else if(mv.Score<best.Score&&depth%2==1)
best=mv;
//undo the move. Remove the piece you just put
if(getIt(height[i],i)==outside)
{ alert("OH JEEZ");
}
}
}
return best;
}
I cannot figure out what is wrong exactly. There maybe a serious error of logic within the function. I posted the .html file on my website www.softdrawing.com/connect4.html with the whole code. If someone could help me fix that function please that would be amazing. I'm new to the minimax algorithm and I tried writing it for myself.

I have this script added to a facebook icon (#id) on my front page: (function() { var e = document.createElement('script'); e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js'; e.async = true; document.getElementById('fb-root').appendChild(e); })(); window.fbAsyncInit = function() { var fbClicked = false; FB.init({appId: 'Myappid', status: true, cookie: true, xfbml: true}); FB.Event.subscribe('auth.login', function(response) { if(response.session && fbClicked){ window.location = 'http://www.mysite.com/facebookauth/?ref=/'; } }); } function thFBShortCut() { FB.login(function(response) { fbClicked = true; if (response.session && response.perms && fbClicked) { window.location = 'http://www.mysite.com/facebookauth/?ref=/'; } }, {perms:'email,publish_stream'}); } function thFBLogin() { fbClicked = true; $('.popbox').fadeOut(); FB.getLoginStatus(function(response) { if(response.session && response.status == 'connected' && fbClicked) { window.location = 'http://www.mysite.com/facebookauth/?ref=/'; } }); } I want when whenever user press on facebook icon, the script should trigger facebook connect app. I added `<div id="fb-root"></div>` right after `<body <?php body_class(); ?>>`, but when I load my site I keep getting these error messages: document.getElementById("fb-root") is null and FB is not defined [Break On This Error] FB.login(function(response) { My html: <a id="facebookicon" onclick="thFBShortCut()">Login</a> What I am trying to do is make a little box that when you hover over it, it will move to a random position. What I am having trouble with is the JavaScript. I have made the code for everything, EXCEPT to move it to a random position. Here is my code so far: Code: <style type='text/css'>
#circle1 {
background:#007fff;
height:20px;
margin:0px;
position:absolute;
width:20px;
left:5px;
top:5px;
-webkit-transition:left 2s linear, top 2s linear;
}
#circle1:hover {
left:25px;
top:25px;
-webkit-transition:left 0s linear, top 0s linear;
}
</style>
<div id='circle1'></div>
I would like the left: and top: in the #circle1:hover to be a random number, to make it go to a random position. I have no clue how to do that though... I was wondering if there's a quick and simple way to notify a user if an ajax connection is broken, for example you're calling a file, but due to your internet connection, the file cannot be relayed back to you, so the existed javascript code on the initial page you're on, notifys you of the problem. Any ideas? Hello, I am very new to HTML. Yesterday I have started learning HTML. I want to make two Dropdown but should be linked with each other. There value should change after click "go" button.

HI, Is it possible to connect to a sqlite database via javascript. And I do not mean the HTML 5 Web SQL Database, that is no problem. What I mean is a file-based SQLite database, which is in the same folder as the HTML page.Also, I can not use something like Google's API, only the javascript libraries I can then put in this folder. THX Helge I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael 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?. Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can... Hi Guys I am trying to modify the functionality of my page. I want to be able to activate this piece of code using another javascript function. This is the code I want to activate: Code: <script type="text/javascript"><!--
$('#button-cart').bind('click', function() {

And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated I want to insert this js snippet Code: function addText(smiley) {
document.getElementById('message').value += " " + smiley + " ";
document.getElementById('message').focus();
return false;
}
to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>');
.... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none'
but how do I insert js in the head of loaded iframe? 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 I wrote a log function that took note of various function calls. Thinking that functions are first class objects, and objects have properties, I made the name of each logged function a property of that function, e.g., brightenInnerPara.name = "brightenInnerPara"; Every browser I tried (Firefox, MSIE, Opera, Chrome, Safari) accepted the assignment, no problem. In Firefox and MSIE, the result was what I wanted: brightenInnerPara.name == "brightenInnerPara" But in the others, the result was: brightenInnerPara.name == null Question 1. Which Javascript is correct here? I favor Firefox and MSIE, not merely because they were willing to give me what I wanted, but also because it makes no sense to accept an assignment statement without throwing an error and then give it a null semantics, like Chrome, Opera, and Safari did. I found a workaround, using assignments like this: brightenInnerPara.prototype.name = "brightenInnerPara"; To my surprise, that worked in every browser. But I don't know why. It seems that such assignments are enough to cause each function to have its own distinct prototype. Question 2. Just how inefficient is my workaround, and why does it work? |
