JavaScript - Simple Webcam Help.
Hi.
i was given a task to set up a simple website to display a picture send by IPcamera to survey a construction site. I found a sample code to do such thing, but there is one problem. IP camera sends pictures with different filenames. I would need some way to pass a filename of the newest .jpg picture to this script, or a way to simply show the newest .jpg in certain folder without defining a file name? Im not sure if this question should be in javascript forum or do i need php for this. Anyway thanks in advance, if someone is kind enough to give advice. Similar TutorialsHi all First post here. Hope someone can help. I have a webcam that is using ftp. I have a script that works for about 10 or less refreshes most of the time then stops. The page I have it uploading to is Here . The code is.... [CODE] <body> <script type="text/javascript" language="JavaScript"> newImage = new Image(); function LoadNewImage() { var unique = new Date(); document.images.webcam.src = newImage.src; newImage.src = "http://www.qsl.net/2d0drm/cam_1.jpg?time=" + unique.getTime(); } function InitialImage() { var unique = new Date(); newImage.onload = LoadNewImage; newImage.src = "http://www.qsl.net/2d0drm/cam_1.jpg?time=" + unique.getTime(); document.images.webcam.onload="http://www.qsl.net/2d0drm/tmp_cam_1.jpg"; } </script> <img src="http://www.qsl.net/2d0drm/cam_1.jpg" name="webcam" onload="InitialImage()" width="320" height="240"> </body> [CODE] I wondered if someone could tell me why it does this? or even ammend any mistakes. I have tried other refresh scripts, but they seem to have refreshes where there are gaps, which is what i'm trying to avoid. I think it just goes out of sync with the uploading cam images. What I like about the script in the link above is(so I believe), it holds the last image until another uploads, so eliminating the gaps. Thanks if you can help Paul Hey guys, I am new to this forum and not extremely experienced with javascript but I know the basics. Anyways, I am trying to create a site similar to this one: Internet Explorer 6 but instead of using an image file like the creator did I would like it to repeat live video from the computer's webcam. I was looking at some webcam plugins and the javascript GetUserMedia function but can't get them to work. Does anyone know if this is possible, and if so how to go about doing something like this? Any help or advice would be greatly appreciated! Thanks! Hello, I am looking to created a login system where a user will take his/her photo via webcam in browser and that picture taken should be related to that user; under a specific timestamp, for example, if my user name is username and I logged In, the system will note my time and by taking a photo (either auto or by clicking a button in browser) and will store that picture in a folder under a unique name related to that customer and the time he logged in, I am stuck how to connect web cam to browser (desirable ajax etc not flash) and then photo taken and stored in a folder with unique name etc anybody did something like this before? help appreciated. Im not sure what type of script it is, but another site i saw had a webcam chat room that was a swf file. I know that flash, but where can i get a script for a Webcam chat room to set up on my site. Thanks I was given this bit of code: Code: <img src="current.jpg" name="refresh" width="306" height="408">
<script language="JavaScript" type="text/javascript">
<!--
image = "current.jpg" //name of the image
function Reload() {
tmp = new Date();
tmp = "?"+tmp.getTime()
document.images["refresh"].src = image+tmp
setTimeout("Reload()",1000)
}
Reload();
// -->
</script>
to refresh a webcam image. I want to know what it means--how often is it set to refresh? I don't know javascript so I can't tell. Is it set to refresh whenever the image is new? or what? I would like to move away from my meta-refresh page-in-an-iframe method of refreshing my webcam if I can. My cam uploads a new image every 5 seconds. I need code that would allow the new image to be seen. Will this code do it? I tried it and it doesn't seem to refresh that often. So what does it do, and can it be tweaked? Hi, I'm trying to get my webcam feed embeded as a flash object. I have the url to the swf generated by the webcam software. If I copy and paste the url into IE's address bar, the webcam shows. However, the same url embeded into html does not work. This directly in IE address bar works. But doesn't in any other browser: Code: http://ipaddresshere/axis-cgi/mjpg/video.swf?resolution=320x240&camera=1 I've looked through the code from the webcam (Axis) admin page and copied the code for the flash option. Here is the code: Code: <html>
<head></head>
<body>
<script language="Javascript">
var width = "320";
var height = "240";
var width_height = 'width="' + width + '" height="' + height + '"';
var view_NeedFlashPluginTxt = "You need a Shockwave Flash plugin, get it from:";
document.write('<EMBED src="http://ipaddresshere/axis-cgi/mjpg/video.swf?resolution=320x240'+'&camera=1" ' +
'quality=high bgcolor=#000000 ' + width_height +
' TYPE="application/x-shockwave-flash" swLiveConnect=TRUE' +
' PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash">' +
'</EMBED>' +
'<NOEMBED>' + view_NeedFlashPluginTxt +
'<a href="http://www.macromedia.com/shockwave/download/">Macromedia</a>.' +
'</NOEMBED><br>');
</script>
</body>
</html>
and this is the html the Javascript outputs: Code: <EMBED height=240 type=application/x-shockwave-flash pluginspage=http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash width=320 src=http://ipaddresshere/axis-cgi/mjpg/video.swf?resolution=320x240&camera=1 swLiveConnect="TRUE" bgcolor="#000000" quality="high"> </embed/> Can anyone spot anything wrong with the code or perhaps suggest why it isn't working? I imagine this would be very simple for someone who knows javascript. I want to have three fields. First field is "posted speed limit", second field is "actual speed" and third field will be the output field. All the script needs to do it subtract the posted speed from the actual speed and add a ZERO to the end; which is the amount of the speeding ticket. The minimum fine is $100, however. So, 5 miles over the speed limit would be $100 (minimum value) 15 miles over the speed limit would be $150 (add a zero) 35 miles over the speed limit would be $350. etc. I know very little Javascript, if anyone could help me out with this, I'd appreciate it. Thanks, Sean Hi Folks, I've been trying to learn Javascript, I'm fluent with CSS, HTML and not to bad with jQuery and PHP. But I've been trying to learn the core fundamentals of JavaScript. Basically, I have a friend who has a strange take on the English language, so I wanted to make him a translator, so that you could input one of his misspellings and it would bring up the proper word. <html> <head> <script type="text/javascript" src="js/modernizr.js"></script> <script type="text/javascript"> // Mox spellings function checkMox () { var bm = document.forms["transMox"]["mox"].value; if (bm == "wid") { document.write("wid = with"); } else { document.write("Please enter a Moxism"); } }; </script> </head> <body> <header> <div id="title"> <h1>I drink!</h1> <h2>Therefor I am...</h2> </div> <nav> <ul> <li>The history of Moxisms</li> <li>Examples of Moxisms</li> <li>The man himself...</li> </ul> </nav> </header> <h3>Welcome to the Big Mox translator</h3> <form id="transMox" action="#output" method="post" onsubmit="return checkMox()"> <input type="text" id="mox">Enter a Moxism</input> <br /> <input type="submit" id="submit" onSubmit="checkMox();">G0!</input> </form> <div id="output"> </div> </body> </html> Obviously that's just for one word, so I wondered how to structure more words into an array or something? Anyway, cheers in advance for the help guys! Hi, Im trying to make an imacro/javascript script that checks a webpage for names, and if either of the names are found, i want the script to alert me, if not, continue looping/reloading the page. Im not at all good with javascript, imacro is more sort of my thing, however what i do have, doesnt seem to do anything. var links = document.getElementsByTagName('a'); for (var i in links){ if (links[i].value == "Simon" || links[i].value == "James"){ alert("ATTENTION"); } } i dont know if its something simple i'm missing, or whether im nowhere near, but ive spent all day trying to do this, and lost all patience. Any suggestion/fixes? Hello, Below is my Javascript, CSS and HTML code for the navigation menu on http://033691f.netsolhost.com/stnew/ -- a test site for my company. Note: I did not write the Javascript code nor do I know how to write javascript. I take no credit. When the page first opens, the navigation shows fully expanded for a second, then collapses all. I would like to cut out the expanded view if possible and have the page load with the menu fully collapsed. Is there any way that would work? Thank you in advance for any input! Code: function initMenus() {
$('ul.menu ul').hide();
$.each($('ul.menu'), function(){
var cookie = $.cookie(this.id);
if(cookie === null || String(cookie).length < 1) {
$('#' + this.id + '.expandfirst ul:first').show();
}
else {
$('#' + this.id + ' .' + cookie).next().show();
}
});
$('ul.menu li a').click(
function() {
var checkElement = $(this).next();
var parent = this.parentNode.parentNode.id;
if($('#' + parent).hasClass('noaccordion')) {
if((String(parent).length > 0) && (String(this.className).length > 0)) {
if($(this).next().is(':visible')) {
$.cookie(parent, null);
}
else {
$.cookie(parent, this.className);

$(this).next().slideToggle('normal');

For the first program I am trying to have the user input the password "stamp" to advance to the next page which is a pizza menu. The first program is supposed to give the user 3 tries and if they do not get it correct an alert is to pop up and tell them how many tries they have left. If they do not get it correct the input field for the riddle is to be locked. However if they have it correct they should be forwarded to the pizza menu. Code: <html>
<body>
<FORM name= "myForm">
<h3> What goes around the world but stays in a corner?</h3>
<br>
<INPUT type="password" name="passPhrase" id="pass">
<script language= "javaScript">
alert("Enter the correct password to proceed");
function checkpass(form)
{
if(form.passPhrase.value == "stamp")
{
alert("page unlocked!");
form.compute.disabled = false;
form.authenticate.disabled = true;
}
else
alert("that is not the correct response!");
</form>
}
</script>
</body>
</html>
For the second program I am having a few small problems, I need to make a button that updates and clears the order. The updated order is supposed to be displayed in the text box that I have at the bottom. Also I am trying to make a function that computes the total cost for the order. Code: </head> <body> <body bgcolor="Silver"> <p> <center> <form method="post" > <p><font size="+4"><strong><font color="#000000">Lance's Pizza <br></font><font size="+4"><strong><font color="#000000"><img src="pizza.jpg" width="163" height="134"></font></strong></font></strong></font></p> <center> <p><strong> Pizza Size:</strong></p> <p> <input type="radio" name="size" value="mini" id="Size_mini"> Mini 14in [$9.99] <input type="radio" name="size" value"=medium" id="Size_Medium"> Medium 16in [$12.99] <input type="radio" name="size" value="large" id="Size_Large"> Large 18in [$15.99] </p> <p><strong>Toppings:</strong>: <center> <input name="toppings" type="checkbox" id="Pepperoni"> Pepperoni [$0.50] <input name="toppings" type="checkbox" id="Suasage"> Sausage [$1.00] <input name="toppings" type="checkbox" id="Greenpeppers"> Green peppers [$0.25] <input name="toppings" type="checkbox" id="Onions"> Onions [$0.25] </p> <input name="toppings" type="checkbox" id="Mushrooms"> Mushrooms [$0.50] <input name="toppings" type="checkbox" id="Olives"> Olives [$0.25] <p> <TEXTAREA NAME="" ROWS="10" COLS="40" onBlur="blurHandlerRouting"> </TEXTAREA> <br><input name="clear" type="button" value="Clear" onClick="Reset();"> </p> </form> </p> </body> </html> http://www.outwarstop.com/woz/woz09r3a.php On this page located around where it says Drops under where it says "Sha-Zhul ArchDemon [60]" are the mouseover's but the location of the popup doesnt come up at the mouse, but on the left side of the table, i need help gettin the popup to appear where the mouse is located. i have this simple js example to click Delete Post and then give the user two options. If they click yes then they go that page...but how do i set it to where when they click cancel it goes back to "Delete Post" ??? i suck at javascript Code: <html>
<body>
<p><b>Delete Post</b></p>
<script type="text/javascript">
window.onclick=function(){
document.getElementsByTagName("p")[0].innerHTML="<b><a href='#'>Delete</a> || Cancel</b>"
}
</script>
</body>
</html>
I have a simple javascript function in a page using the DataTables JQuery plugin, but am having an issue. I have a While loop that cycles through a 2D array of table data. The intent of the loop is to grab the first column on every row of a table, and if there is a value in the column, add it to a running total. I've confirmed that the If statement only executes when there is something in the cell, so that is working fine. Code: function fnCalculateGPA ( ) {
var tableData = $('#myDataTable').dataTable().fnGetData();
var totalCredits = 0;
var i = 0;
while (i <= 21){
if (tableData[i][0]){
totalCredits += Number(tableData[i][0]);
}
i++;
}
alert(totalCredits);
$("div.gpb").html('<b>GPA:</b> <label name="gpa_display">'+totalCredits+'</label>');
}
When I run this as is, the function seems to stall and the alert on the bottom does not even execute. If I take the While loop out and manually loop through the array myself, everything works fine. If I comment out Code: totalCredits += Number(tableData[i][0]); everything is fine, minus the total is not calculated obviously. What on that line is causing the While loop to stall? What am I missing here? I know it is going to be something simple, but this has been driving me nuts for hours now!! Any help would be appreciated. but I just can't figure it out. I have trawled the net for a solution and tried many different things that I have seen but still no luck. Maybe the answer is staring me right in the face and I just can't see it. The code it executing the first time but as the setTimeout tries to start the second loop I get an error 'box is not defined'. Any suggestions and explanations of what I am doing wrong much appreciated! Code: function expand(box) {
var box = document.getElementById(box);
var originalHeight = parseInt(box.style.height);
var inc = 5;
newHeight = (originalHeight + inc);
box.style.height = newHeight + "px";
int = setTimeout('expand(box)',100); }
Hey guys, I'm new to jquery and I'm sure this is a VERY simple problem.. Here's my code Quote: <style type="text/css"> #box { background: red; width: 300px; height: 300px; display: none; } </style> <script type="text/javascript"> $(function() { $('a').click(function() { $('#box').slideDown(4000); }); }); </script> </head> <body> <div id="box"></div> <a href="#">Click Me!</a> </body> </html> As you can see it's pretty simple, I've made the box slideIn. My problem is I want to make a separate button to slide it back out, but because I've used the "a" tag it's associating all links with the same function, how do I get around this? I'm sure it's really simple! Thanks Basically i have an image of a ball that i am trying to make bounce from top to bottom so far it is just going to the bottom and stopping plz help thanks <head> <title></title> </head> <body> <center> <input type="button" value="Click" onClick="moveDown()"/> </center> <img id="Ball" src="ball.jpg" style="position:absolute; top:100px; left:100px;"/> <script language="JavaScript"> var Image = document.getElementById("Ball"); var Position = 100; var direction = 1; function moveDown() { if(direction > 0) { Image.style.top = parseInt(Image.style.top) + 20+'px'; } if(parseInt(Image.style.top)> 100 || direction > 1 ) direction = 1 if(parseInt(Image.style.top)> 500 || direction < 1 ) { direction = -1 Image.style.top = parseInt(Image.style.top) - 20+'px'; } } setInterval ("moveDown()", 50 ); </script> </body> </html> Hi, I need a very simple script that will do the following : I have a HTML form. I have an input call "title". Say I wrote "fleur-de-lys" I have a text area call "text" When I hit the submit button I want to do : 1. Create a HTML webpage with the name in input : fleur-de-lys.html 2. Add the text in "text" somewhere in the body of that new file fleur-de-lys.html 3. Add a preview of that text somewhere in my index page Basically it's like you post a new article on wordpress or whatever, but I just want something simple no database and just need help on how I do this. Thank you very much I'm a student learning javascript, I'm having a very basic problem. I have to write a script that outputs XHTML text that keeps displaying in the browser window that multiples of the integer 2, namely 2, 4, 8, 16, 32, 64, etc. This is the code i have, Code: <!--
var product=2;
while {
product =2*product;
}
document.writeln( +product+ );
// -->
And it pretty much does nothing. Help would be much appreciated Dave |
