JavaScript - [help]creating A Chatbox
I have asked to create a chatbox, which acts just like a messenger which I type a text in the textbox and press send to show output to the messagebox.
However, in my code, I have 2 bugs which is bothering me. The first one is whenever I press spacebar, a "+" sign appear. The second is the first text disappeared whenever I type the second text. Please help me. Code: <html>

Similar TutorialsI need help making new messages appearing at the top of the chatbox, not the bottom. Anyone know how to do that? Also, how can I make it hold only X amount of messages then after X amount of messages it just removes the last one. Thanks This isn't all the code but I figure it has to be something within this code that I have to change. If you want to look at the source code to go http://gifts4points.com and take a look there. Code: //Function for initializating the page.
function startChat() {
//Start Recieving Messages.
getChatText();
}
//Gets the browser specific XmlHttpRequest Object
function getXmlHttpRequestObject() {
if (window.XMLHttpRequest) {
return new XMLHttpRequest();
} else if(window.ActiveXObject) {
return new ActiveXObject("Microsoft.XMLHTTP");
} else {
document.getElementById('p_status').innerHTML = 'Status: Cound not create XmlHttpRequest Object. Consider upgrading your browser.';
}
}
//Gets the current messages from the server
function getChatText() {
if (receiveReq.readyState == 4 || receiveReq.readyState == 0) {
receiveReq.open("GET", 'getChat.php?chat=1&last=' + lastMessage, true);
receiveReq.onreadystatechange = handleReceiveChat;
receiveReq.send(null);
}
}
//Add a message to the chat server.
function sendChatText() {
if(document.getElementById('txt_message').value == '') {
alert("You have not entered a message");
return;
}
if (sendReq.readyState == 4 || sendReq.readyState == 0) {
sendReq.open("POST", 'getChat.php?chat=1&last=' + lastMessage, false);
sendReq.setRequestHeader('Content-Type','application/x-www-form-urlencoded');
sendReq.onreadystatechange = handleSendChat;
var param = 'message=' + document.getElementById('txt_message').value;
param += '&name=<?php echo $_SESSION['login']; ?>';
param += '&chat=1';
sendReq.send(param);
document.getElementById('txt_message').value = '';
}
}
//When our message has been sent, update our page.
function handleSendChat() {
//Clear out the existing timer so we don't have
//multiple timer instances running.
clearInterval(mTimer);
getChatText();

If you go to a Youtube video by Justin Bieber or Rebecca Black, comments are constantly being posted and it seems like the autorefresh for the comments kicks in every half second. I don't plan on having millions of users viewing my page, but still, wouldn't having every user make a [mysql] request to the server every half second really take a toll on the server (especially since I don't plan to ever have the resources that Youtube has)? Facebook also seems to have instantaneous auto-refreshes, be it in comment boxes or their chat interface. So what would be the best method to implement a near-instantaneous autorefresh system with minimal resource usage? i need to create a div as i click down and move while pressing the mouse button and the div will increase in size as i move the mouse while still pressing the mouse button. how can i accomplish this task Hi i am looking to create a js pop up to display an amazon widget which relates to an item on my page. so i've found this on the net http://blazonry.com/javascript/windows.php but im not very javascript minded and dont know where to start. so i have tried this Code: <img src="images/listen.png" border="0" alt="Preview Songs" title="Preview Songs" onclick="window.open("song_preview.php?id=<?php echo $row['ASIN']?>","Window1","menubar=no,width=430,height=360,toolbar=no");" />
but it loads a blank pop up at the same time the page loads up and not when an image is clicked? plus when i first loaded the page it said pop up blocked which sucks!! on the example i didnt get that, any reason why??? any help is appreciated thanks Luke If anyone is planning on buying "ICAB4225B Automate Processes" in relation to a TAFE/College/School course, I suggest getting the teacher to actually READ the book before they use it. Tonight has been a HE-Double Hockeysticks (Not sure on language in this forum) of fixing mistakes the book has made. Double commars inplace of singles, singles inplace of doubles, single brackets, whole chunks of text that are wrong. In one place in the book it tells me to copy the text in blod and there is none. Anyway.... The code that the book has made me piece together over the last few questions has left me with: Code: <script type = "text/javascript">
{
var counter = 0
var NoOfItems
var ItemsNames = new Array()
NoOfItems = prompt ("How many items do you want to hock?","");
for (NameCount=0; NameCount<NoOfItems; NameCount++)
{
ItemNames [NameCount] = prompt ("What are the names of your items?","");
}
document.write ("<form name='myform'><br><table>");
while ( counter < NoOfItems)
{
document.write ("<tr><td><value>Enter the price of the " + ItemNames [count] + "</td><td><input type='text' name='" + ItemNames [count] + "'></td></tr>");
counter++
}
document.write ("<tr><td><input type='submit' value='Submit Details' onClick='validateform'</td></tr></table></form>");
}
</SCRIPT>
The problem I am having it with the Array. I dont think that var = new Array is correct but thats what my text book is telling me. Any help? Alright I have never really created a class before and I have to for a project. This is what I have so far and I will try to explain the requirements I am looking for thoroughly and what problems I am having. Code:
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<script language="javascript" type="text/javascript">
function clock () { //Object Constructor
this.setT = function() { //Method Set Time
//Properties
this.currentTime = new Date ( );
this.currentHours = this.currentTime.getHours ( );
this.currentMinutes = this.currentTime.getMinutes ( );
this.currentSeconds = this.currentTime.getSeconds ( );
}
clock.prototype.displayTime = function () {
clock.setT
}
}
</script>
<body>
<form name="form1">
<p>
<input type="text" rows=7 cols=60 name="currentTime">
<br>
<input type="button" value="Set Time" onClick="clock.displayTime();">
<br>
<input type="button" value="Display Time" onClick="currentTime.value= completeTime;">
<br>
<input type="reset" value="Reset">
</p>
</form>
</body>
</html>
The clock class contains: Three Properties: Hours Minutes, Seconds Two Methods setTime (which uses date class to get current time) Must be defined in the constructor displayTime (returns a string displaying current time) Must be defined as a prototype property of constructor The below is a very rough outline, and probably not correct. I've been reading up on objects for the last few hours and can't be very sure of anything yet. Code: function clock() {
this.currentTime = new Date ( );
var currentHours = currentTime.getHours ( );
var currentMinutes = currentTime.getMinutes ( );
var currentSeconds = currentTime.getSeconds ( );
this.setTime = function() {
}
}
clock.prototype.displayTime = function ( ) {
}
I guess my biggest problem now is the outline. Any help would be great hopefully once i get what goes where i can actually start writing the code. I already have the full code to write a basic clock just like this but it doesn't use classes or any of this. so now that i figured out how to add items in an array and i got the percent of each item from the total i have a table that looks something like this...(sorry the alignment is screwed up) Name Votes Percent 1.2.3.4.5.6.7.8.9.10..... Bob 45 14% Bill 86 26% George 122 37% Sam 79 24% the numbers One through Ten represent empty columns (i technically need 100 but i didnt write that out yet... so what i am trying to do is initially take the number i get from the percentage and fill in the amount of cells with a certain color.... so 14% would fill 14 of 100 cells..and this would create a bar graph..In theory I know how it should work I just can get any of the right syntax..here is the code i am working with... Code: var votes = new Array();
votes[0] = 45;
votes[1] = 86;
votes[2] = 122;
votes[3] = 79;
var ppl = new Array();
ppl[0] = "Bob";
ppl[1] = "Bill";
ppl[2] = "George";
ppl[3] = "Sam";
//var party = new Array();
//party[0] = "(D)";
//party[1] = "(R)";
//party[2] = "(I)";
//party[3] = "(G)";
function getPercent(){
var theSum = 0;
for(var i = votes.length;i--;)
{
theSum += votes[i]
}
for(i=0;i<ppl.length;i++)
{
document.write("<tr><td>"+ppl[i]+"</td><td>");
document.write(votes[i]+"</td><td>");
var pct = document.write(Math.round(votes[i]/theSum*100)+"%"+"</td></tr>");
}
//var total = document.write(numbers[numbers.length-1]); *property to get array length
}

thanks in advance for any help! hi i am new to javascript. i make a mcq quiz website in one of server side script. now for that website i want to make count down timer so when that quiz starts the user will have 5 minutes to complete that quiz if use does not able to complete quiz in given time then quiz should disable and shows the user score how can i achieve this Hi everyone, I want the source code of creating forum in JavaScript language.ASAP

Hey All, I've currently working on making a calendar for my website. How do I go about creating a password for it? So that the admin can add events to it. Cheers Guys!!! Hello, The following web page is an essay, but there is JavaScript code in the head area: http://www.pinyinology.com/content/content3c.html You can see the 'Press F5 to reset' command, and please try it to see what happens. What I like is to create another command 'Click here to reset'. Therefore, there will be two commands for the reset task. Then it becomes: Click here or press F5 to reset. The press F5 stuff in the code is as follows; Code: //Typewriting code
message='<span id="inTxt">wen<sup>2</sup></span>';
pos=0;
maxlength=message.length+1;
function writemsg()
{
if (pos<maxlength)
{
txt=message.substring(pos,0);
document.getElementById('edit').innerHTML=txt;
pos++;
timer=setTimeout('writemsg()', 20);
}
}
//Typewriting code2 own addition
message2='<span id="inTxt2">wen<sup>2</sup>闻. ven<sup>2</sup>:文纹. win<sup>2</sup>:蚊. vin<sup>2</sup>:雯.';
pos=0;
maxlength=message2.length+1;
function writemsg2()
{
if (pos<maxlength)
{
txt=message2.substring(pos,0);
document.getElementById('listing').innerHTML=txt;
pos++;
timer=setTimeout('writemsg2()', 20);
}
}

Thanks in advance for your help. I have searched and scoured the web looking for a script like this. I have found different scripts that do certain aspects of what I am looking for, but not ONE that does it all. I am hoping you can help bring my search to an end! I need a script that when a user tries to leave a page, either by typing in a URL in the address bar or clicking an external link they get a Javascript (not pop up window) dialog box asking if they would like to complete a survey. If they click OK they are then redirected to the survey page. If they click cancel it allows them to go on their way to the external link. It needs to be able to decipher between internal and external links. The script needs to work with both IE and FF. This is a must. Safari would be a plus. I would like, BUT IS IN NO WAY A NECESSITY, for the script to also be cookie based in that the user doesn't see it if they've seen it within 7 or 14 days. I really hope you all can help me here as I am lost! If you need any other info from me please let me know! Hi, my name is Joe. I have no expierience in writting scripts buy have managed to put together what I think is a decent website for a local business. It is a local Bait & Tackle shop. I have done this for free as I am retired and work a few days a week in the owners shop. This is my situation. I wish to display the current days high tides in a web page. I have created a database (csv file) which resides on my server This file has two fields: date and tidal times I am looking for a script that test the "date" field and if it is equal to the current date, display the tidal field. Any help would be appreciated. Thanks, I would like to create a slideshow like what most wedding sites have but I would like to have some fancy transitions like "Random dissolve, checkerboard, spiral" e.t.c, how can I add any of those to my slideshow, this is a regular fade slideshow I have: Code: var speed=40; /* this is the image fade speed - higher value=slower, lower value=faster */
var timer=4000 /* this is the time that each image is static - 4000=4 seconds */

I have just completed my JS studies and wish to try 3 things to test what I have learned, first I wish to create a simple animation, then I'll attempt my own slideshow and last a specific script. First, can I try the animation on this specific forum? If not then is there another forum for this on this board or do I have to go to an animation specific site please?
Hi,there, my following script generates random numbers and if random number==1 the background color of textbox="red"; so far it works fine.. What I m tring to do is to tell my script to write amessage in the same textbox after 5 seconds so ı need a delay function.. thanks for help PHP Code: <body bgcolor="pink"> <script> stopx=setInterval("gox()",500); function gox() { var box1=document.getElementById("box1"); var box2=document.getElementById("box2"); box1.value=Math.floor(Math.random()*5); if(box1.value==1) box2.style.backgroundColor="red"; ////////////// // I need a delay function here; // ////////// //???// if(delay==5) box2.value=" 5 seconds passed ,now I will give another message"; } </script> <input type="text" id="box1" style="position:absolute;top:50px;left:20px;width:40px;height:20px;"> <input type="text" id="box2" style="position:absolute;top:50px;left:200px;width:200px;height:50px;"> <input type="button" value="try again" onclick="location.reload()" style="position:absolute;top:250px;left:20px;width:60px;height:50px;"> Hi all, As I scan each line of data that was entered into a textarea box, I need to call a function once I come across a line that starts with the following: Code: "0 B3C 0020365077 0045740301 3 09FEB2008 09MAR2010 " (without quotes) I have created the following legend to help with the creating a regular expression that will validate when I have found a line that needs further processing: N - number L - letter A - letter or number S - space So using the above legend, the first 51 characters of the line that I need to validate should always be in the following format: Code: "NSAAASSAAAAAAAAAASNNNNNNNNNNSASNNLLLNNNNSNNLLLNNNNS" (once again, without the quotes) I have been reading a few articles on JavaScript regular expressions but am a bit lost at this point as how to start? |
