JavaScript - Shared Whiteboard In Javascript
I am looking for a multi-user whiteboard (for personal use) similar to the one at http://www.danga.com/misc/jsdraw/xmlhttp.html. I have already tried Google. There are alot of them out there but non available for download to run on my site.
Similar TutorialsDoes someone know what the JavaScript for checking if an user have "liked" and "shared" on Facebook? As far as I know, you can not check if they've shared, but only if they've clicked the button. I don't know if you can make them like to view, but it would be nice to get that piece of code too, if obtainable. I'm going to use it for a website where you have to "like" a fb page shown, and have to share the website. If someone can provide it, I'd also like a guide on timers /foldager how to search through siblings for shared attributes I have a a long list of links and I suppose Im going to apply a number of classes to each one [describing a number of attributes for each] and I want to do a conditional search probably in javascript/jquery so that when i hover over one of the links I highlight its relatives - those that have the same attributes. What Im having trouble wrapping my head around is the idea of classes to ID these custom attributes. The attributes are coming from a database converted to XML. In my Javascript I essentially want to say that for each link should the user mouseover or mouseclick for each of its sibling links if its sibling link share its attributes style or highlight these compliant siblings a certain way how do I do the 'if statement' without spelling out every possible attribute entry? I know in plain OOP Java how I could test for this but in that scenario I have access to these entries as fields in an object's instantiation. Help? thanks so much in advance Hello everyone I am new to JS and it has been years since I worked with JAVA or HTML but I'm getting back into it for a pet project of mine and could really use some help getting past this small problem in front of me. ok so here is my issue: I have an HTML page that will read information from Cells in an MS Excel spreadsheet then will write them to the screen. This works if I run it localy and use the direct path like C:\MyFolder\ExcelFile.xls BUT if I try and access the MS Excel spreadsheet from a shared network drive like \\TheComputerName\MyFolder\ExcelFile.xls the JS will not read the file. SO... I tried to leave the HTML file and the Excel file localy and then tried to open teh HTML file from a shared computer like \\TheComputerName\MyFolder\MyWebFile.html but that wouldn't work ether. NOW my question to you guys is how can I get my HTML file to read the Excel file from a Network Shared location... ....AND.... ....How do open the HTML file from a Shared computer (while still correctly reading the Excel Spreadsheet) Please help (and use small words and code for my little brain) and thank you. PS I was wondering if this could even be done in JS, I was wondering if I need to do this in PHP instead which I have NO idea at all. 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. 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 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 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!

Thanks 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?. I want to insert this js snippet Code: function addText(smiley) {

to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>');
.... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none'
but how do I insert js in the head of loaded iframe? Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>
<option value="../komik4/|20">Judul Komik4</option>
</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$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() {
$.ajax({
url: 'index.php?route=checkout/cart/update',
type: 'post',
data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'),
dataType: 'json',
success: function(json) {
$('.success, .warning, .attention, information, .error').remove();
if (json['error']) {
if (json['error']['warning']) {
$('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.warning').fadeIn('slow');
}
for (i in json['error']) {
$('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>');
}
}
if (json['success']) {
$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.success').fadeIn('slow');
$('#cart_total').html(json['total']);
$('html, body').animate({ scrollTop: 0 }, 'slow');
}
}
});
});
//--></script>
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 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? Hi! Well i dont usally ask for help but this one has got me scratching my bum .. i mean brain any way! I need help, i have a shoutbox, and there is a button on it! when its pressed it asks a user to insert a 'track' they want played on the radio! and it submits it to the radio [tune*] [*/tune] BBCODE is the format so, because it can be used by any one i want it limited so you can only click it twice! However i cant get it to work can i get some help, here is the cutout from the function Code:
customInsertTrack: function()
{
var ClickCount = 0;
var clickLimit = 2;
if ( !ipshoutbox.global_on )
{
Debug.error("function available only for the global shoutbox");
return false;
}
if(ClickCount>=clickLimit) {
alert("You can only request a tune "+clickLimit+" times per 2 minutes!");
return false;
}
else
{
var track = prompt("Send The UK Hardcore A Song Request","ENTER YOUR TRACK HERE");
ClickCount++;
if ( track == false || track == null || track == '' )
{
return false;
}
// Parse properly emo_code
track = track.replace( /"/g, '"' );
track = track.replace( /</g , '<' );
track = track.replace( />/g , '>' );
track = track.replace( /&/g , '&' );
/* Insert it into our textarea/input field */
$('shoutbox-global-shout').value = "[tune]" + track + "[/tune]";
ipshoutbox.shoutAjax.submitShout();
return true;
}
}
ALSO if possible, can i limit this to twice per hour ??? Thanks in advanced! hello alll i need help about script i want to know how to know what is write here??

I am working on an assignment. I will be upfront about that. I am not looking for someone to write my code for me. I do have the algorithm laid out and I'm almost positive this algorithm will work. I am a computer science student who has programmed in everything from assembly type languages to C/C++, .NET, JAVA and others. I am well educated in the concepts of programming and good programming practices. Having said all that one thing that annoys me the most is when I know what I want my code to do but I have a hard time finding out how to get the required language to do that. Take all that and then throw it on to the big ole mess of now I need to write up an HTML form (easy) and have JavaScript "process" the form and using that make a table (graph really) to be inserted into the .innerHTML of the body in said web page. So I have my form coded and my logic worked out. There are two buttons at the bottom of this form entitled "submit" and "reset". Naturally the reset button puts the form fields back to their default values. However that is the only part of my assignment that works. My idea was to write a JavaScript function that would execute when the user clicked the "make table" button. The JavaScript function would assign all the form field values to variables and then it would proceed to make a table and fill it in based upon those values. The beginning and end of the table code would just be "inserted" into the table string but the middle parts would be generated by a loop and the variables I got from the form field values. After all this good stuff is done, JavaScript should insert this "HTML String" into the .innerHTML section of a <body> tag. Sounds like it should be simple, but I can't even get JavaScript to read the form field values into variables like it "should". I can use the document.FORMNAME.FORMFIELD.value method but I'm supposed to use the document.getElementByID() method to do it. So I want to pass the entire form to my "Make Table" function and then from there use the statement variable1 = document.getElementByID(fieldname).value for each fieldname and then I would have all my field "values". From there I would need to generate a table "string" which is html code to be inserted into the .innerHTML of the <body>.... getElementByID() is doing nothing for me right now. So I'm stuck there for the moment. Here is my code: [CODE] <html> <head> <script type="text/JavaScript"> var lbl1 = "fish" ; function MakeTable() { lbl1 = document.getElementByID('label1').value; alert(lbl1.value); } function printvar() { document.writeln(lbl1); } </script> </head> <body> <form name="myform"> <h1> Author:</h1> <!-- Start of first form line --> <input type="text" id="addcolor" /> <input type="button" value ="Add Color"> <br/> <!-- End of first form line --> <!-- Start of second form line --> Label 1: <input type="text" id='label1' value="USA"> <select id="colors"> <option value ="Black"> Choose One</option> <option value="Red">Red</option> <option value="Blue">Blue</option> <option value="Yellow">Yellow</option> <option value="Green">Green</option> <option value="Purple">Purple</option> </select> Value: <input type="radio" id="num" value ="1" /> 1 <input type="radio" id="num" value ="2" /> 2 <input type="radio" id="num" value ="3" /> 3 <input type="radio" id="num" value ="4" /> 4 <input type="radio" id="num" value ="5" /> 5 <br/> <!-- End of second form line --> <!-- Start of third form line --> Label 2: <input type="text" id="label2" value="England"> <select id="colors"> <option value ="Black"> Choose One</option> <option value="Red">Red</option> <option value="Blue">Blue</option> <option value="Yellow">Yellow</option> <option value="Green">Green</option> <option value="Purple">Purple</option> </select> Value: <input type="radio" id="num" value ="1" /> 1 <input type="radio" id="num" value ="2" /> 2 <input type="radio" id="num" value ="3" /> 3 <input type="radio" id="num" value ="4" /> 4 <input type="radio" id="num" value ="5" /> 5 <br/> <!-- End of third form line --> <!-- Start of forth form line --> Label 3: <input type="text" id="label3" value="South Korea"> <select id="colors"> <option value ="Black"> Choose One</option> <option value="Red">Red</option> <option value="Blue">Blue</option> <option value="Yellow">Yellow</option> <option value="Green">Green</option> <option value="Purple">Purple</option> </select> Value: <input type="radio" id="num" value ="1" /> 1 <input type="radio" id="num" value ="2" /> 2 <input type="radio" id="num" value ="3" /> 3 <input type="radio" id="num" value ="4" /> 4 <input type="radio" id="num" value ="5" /> 5 <br/> <!-- End of forth form line --> <!-- Start of fifth form line --> Label 4: <input type="text" id="label4" value="Poland"> <select id="colors"> <option value ="Black"> Choose One</option> <option value="Red">Red</option> <option value="Blue">Blue</option> <option value="Yellow">Yellow</option> <option value="Green">Green</option> <option value="Purple">Purple</option> </select> Value: <input type="radio" id="num" value ="1" /> 1 <input type="radio" id="num" value ="2" /> 2 <input type="radio" id="num" value ="3" /> 3 <input type="radio" id="num" value ="4" /> 4 <input type="radio" id="num" value ="5" /> 5 <br/> <!-- End of fifth form line --> <!-- Start of fifth form line --> Label 5: <input type="text" id="label5" value="Congo"> <select id="colors"> <option value ="Black"> Choose One</option> <option value="Red">Red</option> <option value="Blue">Blue</option> <option value="Yellow">Yellow</option> <option value="Green">Green</option> <option value="Purple">Purple</option> </select> Value: <input type="radio" id="num" value ="1" /> 1 <input type="radio" id="num" value ="2" /> 2 <input type="radio" id="num" value ="3" /> 3 <input type="radio" id="num" value ="4" /> 4 <input type="radio" id="num" value ="5" /> 5 <br/> <!-- End of fifth form line --> <!-- Make Table and Reset Buttons--> <input type="button" value ="Make Table" onclick="MakeTable(myform)" > <input type="Reset" value ="Reset" > </form> </body> </html> [CODE] any help would be appriciated I'v very new to javascript and need some help. Here's what I need to do: I need to have a text input with a button, and when the button is clicked the text must be copied to a div. When copying, each character needs to be placed on a separate line within that div container. Before this happens though, the content currently in the div must be cleared. This probably very simple, but as I said i'm new and confused out the wazoo. Thanks in advance! i really need an expert definition, please!! thank you, you are to SWEET!!
Hi there, I am trying to make a Google Map that has markers on it which when clicked display a users latest tweet. I have used the code found here to generate the latest tweet for a single user. But as this map will have multiple points of user submitted data I need something that can display multiple user tweets. So far, the user clicks on the map and enters their details, their name should be their twitter username. The data is saved to an xml file. At the moment the code is set up so that when you click on a marker it just displays your username and address. But I want to somehow include the PHP to show the users latest tweet. Here is the Javascript: Code: function readData() {
var request = GXmlHttp.create();
request.open("GET", "http://mydomainname.com/test/phpsqlinfo_result.php", true);
request.onreadystatechange = function() {
if (request.readyState == 4) {
var xmlDoc = GXml.parse(request.responseText);
// obtain the array of markers and loop through it
i=[0];
markers=[0];
map.getInfoWindow().hide();
gmarkers = [];
map.clearOverlays();
side_bar_html = "";
var markers = xmlDoc.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
// obtain the attribues of each marker
var lat = parseFloat(markers[i].getAttribute("lat"));
var lng = parseFloat(markers[i].getAttribute("lng"));
var point = new GLatLng(lat,lng);
var label = markers[i].getAttribute("name");
var address = markers[i].getAttribute("address");
var type = markers[i].getAttribute("type");
var html = label + '<br />' + address + '<br />' + type;
// create the marker
var marker = createMarker(point,label,html);
map.addOverlay(marker);
}
// put the assembled side_bar_html contents into the side_bar div
document.getElementById("side_bar").innerHTML = side_bar_html;
}
}
request.send(null);
}
readData();
And here is the PHP: Code: <?php
function getTwitterStatus($userid){
$url = "http://twitter.com/statuses/user_timeline/$userid.xml?count=1";
$xml = simplexml_load_file($url) or die("could not connect");
foreach($xml->status as $status){
$text = $status->text;
}
echo $text;
}
//insert user id where it says userid
getTwitterStatus(userid);
?>
In the Javascript is there a way to include the PHP code, and in the PHP is there a way to include the variable "label" (which is declared in the javascript" where it says user id in "getTwitterStatus(userid)? I'm quite new to all this, so any help would be really appreciated! |
