JavaScript - Javascript Stopwatch That Can Divide Seconds On Display In Html Form
Hi guys!
I have a simple JavaScript stopwatch that displays the time using an html form with start/reset and clear buttons. Basically I'm making a speed calculator that converts seconds into MPH. All I need it to do is divide whatever the amount of seconds are by 40.91. So instead of it displaying the seconds being counted up (i.e. 2 seconds, would displayed as 20.455 MPH). Does that make sense? JavaScript is not my strong suit, and It's got me stumped. JavaScript: Code: var t=[0, 0, 0, 0, 0, 0, 0, 1];
function ss()
{
t[t[2]]=(new Date()).valueOf();
t[2]=1-t[2];
if (0==t[2])
{
clearInterval(t[4]);
t[3]+=t[1]-t[0];
t[4]=t[1]=t[0]=0;
disp();
}
else
{
t[4]=setInterval(disp, 43);
}
}
function r()
{
if (t[2]) ss();
t[4]=t[3]=t[2]=t[1]=t[0]=0;
disp();
t[7]=1;
}
function disp()
{
if (t[2]) t[1]=(new Date()).valueOf();
t[6].value=format(t[3]+t[1]-t[0]);
}
function format(ms)
{
var d=new Date(ms+t[5]).toString()
.replace(/.*([0-9][0-9]:[0-9][0-9]:[0-9][0-9]).*/, '$1');
var x=String(ms%1000);
while (x.length<3) x='0'+x;
d+='.'+x;
return d;
}
function load()
{
t[5]=new Date(1970, 1, 1, 0, 0, 0, 0).valueOf();
t[6]=document.getElementById('disp');
disp();
}
HTML form: Code: <input type='text' id='disp' maxlength=12 readonly /> <button type='button' onclick='ss()' id='butt' data-inline="true">Start/Stop</button> <button type='button' onclick='r()' id='butt2' data-inline="true">Reset</button> Any help is greatly appreciated!!! Similar TutorialsHi people, I'm building an online psychological experiment in which I need to display an image for 5 seconds on the screen. Does anyone has a simple script for that? I found some script that does image rotation but its not exactly what I am looking for. First, the rotation of the images doesn't stop and second I don't need something so elaborate. This is the script that I found. Code: <SCRIPT LANGUAGE="JavaScript">
<!--
var dimages=new Array();
var numImages=2;
for (i=0; i<numImages; i++)
{
dimages[i]=new Image();
dimages[i].src="images/image"+(i+1)+".jpg";
}
var curImage=-1;
function swapPicture()
{
if (document.images)
{
var nextImage=curImage+1;
if (nextImage>=numImages)
nextImage=0;
if (dimages[nextImage] && dimages[nextImage].complete)
{
var rel="nofollow" target=0;
if (document.images.myImage)
rel="nofollow" target=document.images.myImage;
if (document.all && document.getElementById("myImage"))
rel="nofollow" target=document.getElementById("myImage");
// make sure target is valid. It might not be valid
// if the page has not finished loading
if (target)
{
target.src=dimages[nextImage].src;
curImage=nextImage;
}
setTimeout("swapPicture()", 5000);
}
else
{
setTimeout("swapPicture()", 500);
}
}
}
setTimeout("swapPicture()", 5000);

Thanks I'm trying to display the elements in an array but doesn't seem to work: Code: var myurl=new Array("google.com", "yahoo.com");
for (i=0;i<=myurl.length-1;i++){
document.writeln("<a href='http://www.' + myurl[i] + target='_blank'>");
}
Not sure why it is not working?? I have a javascript file and a html file. On the html file I have an action (button) and would like to use some type of attribute of the onclick to call my function to open this html file. below is the beginning of my function: requestPanel_Forwardme: function() { view.opendialog("show_me") What other attributes of action can I use? can this function in my JS file be called and if so how would I call it? <action?? Hey, I'm looking for different JS form validation techniques. I've seen quite a few but nothing that really stands out. I'm particularly interested in finding design techniques...ie: how and where are the errors displayed inside a form? I realize that I can't count on JS for validation, but I'm trying to add an assistive technology to make a web form feel more like a web application. I'd love to see your favorite way of displaying form errors via JS. I've got a few of my own but if you've ever tried to do this you know it's a difficult problem to handle the general case. Thanks! Very naive coding question... i'm a novice coder and i think javascript is the solution i need but - maybe there's better ways... Ok - my website accepts a login password to access certain pages. Depending on the password entered i set a javascript variable to either 'true' or 'false'. If the variable is set to 'true' then i want to give the user access to shopping cart buttons, if 'false' then the shopping cart buttons should be hidden. My current solution is to wrap javascript around each shopping cart button and display only if the variable is set to 'true'. The shopping cart button looks a bit like this: Code: <form method="post" action="http://www.shoppingcart.com"> <input type="hidden" name="product" value="product" /> <input type="hidden" name="price" value="9.99" /> <input type="hidden" name="return" value="http://www.home.com"/> <input type="submit" value="add to basket" /> </form> I've tried displaying this using document.write() - but it gets confused when it encounters the ":" in the web address. Also i get the impression from trawling the forums that document.write is not flavour of the month these days. And another thought - I accept the variable on one page - then move to multiple other pages to reference it.... will the variable still be there when i move to other pages or do i need to somehow pass it across each time? Trying to keep my coding XHTML compliant... Any pointers and idiot proof suggestions would be much appreciated. hi this is santosh first off all thanks in advance to all who r reading my question im in prblm in my project in 1 file i have to first display textbox in html statically which will hav + & - button preceding it , & on click of + button one more textbox should appear dynamically & first textbox + button should disapper & it should hav only - button & the textbox which was dynamically generated now on click of first textbox + button should hav + & - button & it should go on. & on click of - button textbox which is in front of it should get deleted. here i tried alot but my code is showing + & - button to every textbox that is dynamically generated which is not the requirement plz help me im in great need. earlier also i hav submitted my queries & got a fully satisfied result bcoz of that now im having great hopes from u & this site plz reply as early as possible waiting for ur reply again thanks in advance Hi, I've built a sorting table for what will (hopefully) be a leaderboard for Forza 4. I have the table sorted properly and my current script (within the table) adds up all three T columns and brings the total to 72.001 as expected, woot! Where I'm stuck is converting the 72.001 to 1 minute 12.001 seconds (1:12.001) and I need to have it include the thousandths since the game gives that information. Once I get the JS going for the top row I can copy down Any advice on converting this is greatly appreciated and I Bolded the JS I'm referring to: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Oh, and any help on centering the result in the cell (72.001) would be excellent too, thank you. Jerome Hello and thank you for you help, we have a problem in our currently built website, in chrome+firefox the website works great but in IE 7+8+9 the javascript stops working after few seconds or after several commands a user do in the website. the url is : http://www.triver.co.il if any one know what can be the issue it will be great thank you ! Hi All, I have a button in my html form that will process some functions when user clicks on the button. The problem is after processing the functions, the result is not displayed in the form where I want it to be displayed. I want to ask whether we can create table in the function and display the result in the table row/column but in the same form. Is this possible to be done? And how to do this? In this form cpiM, the input button will call function showIndex. Code: <tr> <td><input type="button" value="Enter" onclick="showIndex(document.cpiM.currFrom.options.selectedIndex, document.cpiM.currTo.options.selectedIndex, document.cpiM.base.options.selectedIndex, document.cpiM.country.options.selectedIndex)"> </td> <td><input type="button" onclick="frmResetM()" value="Reset form" /> </td> </tr> In this function, I want to display the result of calcIndex right below the button Enter in the form cpiM. Code: function showIndex(frm, to, base, country)
{
for (i=frm; i<=to; i++)
{
document.write(calcIndex(i, base, country));
document.write("<br/>");
}
}
Hi all - first post - I'm not too hot on javascript so I don't know if this can be done nor how to search for it in the forum because I don't know what keywords to use - but if I give an idea of what I want to do, perhaps someone can suggest an idea of how to proceed? I have two left floated divs - in the left div I want a series of drop downs (possibly check boxes as well) about a series of products. When the user makes their decision and presses submit, I want the form to submit to a javascript function that says "Right, you will need, from your responses, product C" and in the right hand floated div, a series of hidden product info divs whose visibility is changed depending on which product the function determines is the one for you. Broken down into parts I think I need to do the following: a) Standard HTML form with drop downs etc and submit b) Hidden divs c) Submission process locally to javascript function to determine which product to show/hide d) Javascript function that makes the decision e) Javascript that hides/shows products Unfortunately a server side option is not available; it has to be a client side solution and I only could think of javascript. I can probably handle all bar c) and d) - any pointers, help or suggestions would be great thanks! cheers frank Ok so I'm making a limited snipe Bot on ROBLOX.com that basically buys the limited for a price that you input. It works with purchasing the limited. When I enter it in console it immediately buys the limited up for the maximum price or less.

hi everyone, I am currently working on a stopwatch and I can't for the life of me get it inside this textbox.. Can anyone help with it? no matter what I seem to try it always goes outside of it... Code:

var setT, h, m, s;
function startWatch(b){
var ticker=document.getElementById('ticker');
var HH=h<10?'0'+h:h;
var MM=m<10?'0'+m:m;
var SS=s<10?'0'+s:s;
ticker.innerHTML = HH+':'+MM+':'+SS;
if(!b){stopWatch();return}
s++;
if(s==60){s=0;m++}
if(m==60){m=0;h++}
setT=setTimeout(function(){startWatch(b)},50)

I've been working on a stopwatch script and being fairly familiar with Javascript I've coded the following... function y() { setTimeout("x()",1000) } function x() { var a=0; var b=0; var c=0; var d=0; for(i=0;i=1;i=i+0); { txtbox1.value=a + b + ":" + c + d; d++; if (d==10); { d=0; c++; } if (c==6); { d=0; c=0; b++; } if (b==10); { d=0; c=0; b=0; a++; } } } </script> <input type="textbox" name="txtbox1"> <input type="button" name="b1" value="Start timer" onclick="y()"> Hi there. I am wanting to create a countdown timer that is based on a SELECT feature. If a user selected 15 MINUTES, the script would know 15 minutes was selected and would prompt start to time down when selected. Or if the user selected 30 MINUTES it would go to countdown from 30 minutes. I would also like a stopwatch feature on there if STOPWATCH was selected. It would also be great if when counting down the background box of the timer turns red to visually show the timer had gone over and start counting back up in minus to show how many minutes/seconds it has gone over. I've looked on good old Google but can't find a code i'm looking for! Thanks Ash I have a php file lets say file1.php, that printing a variable, its dynamic numbers output that already always increasing, like private message numbers that coming or others : PHP Code: <?php echo $variable ?> i want to put that variable output, in another files page title, lets say file2.php or file3.html, in the front of the another files page titles, and auto refresh every x seconds, maybe like this : Quote: (1) - another text in the page title after x seconds, get a private message Quote: (2) - another text in the page title after another x seconds, get another private message Quote: (3) - another text in the page title or its ok if just like this, only the variable, without the another text in the page title Quote: (1) please share your knowledge to make it, maybe using javascript, jquery or others hi, im new, so hey, great forum. I'm hoping someone can help - Im looking for a js stopwatch that would express a figure input by the end user - so for example the code could ask 'how many calories do you burn an hour' - user inputs 100 They start the stop watch and the stop watch show both the seconds/minutes increasing, but also show the calories increasing as (input="100"/60)/60 can anyone point in the right direction? many thanks Hey guys, I've never use JavaScript before so bare with me. But, I have a registration form, and I want to have a location field in it, and then a region field that changes depending on what the user set as their location. But, I cannot get it to work, and I have no idea of how to go about doing it. Here is the JavaScript I have been using so far: Code: function toggleTable(select)
{
if(select.value == "uk")
{
select.value = "uk";
document.getElementById("region2").style.visibility = "collapse";
document.getElementById("region1").style.visibility = "visible";
}
else if(select.value == "usa")
{
select.value = "usa";
document.getElementById("region1").style.visibility = "collapse";
document.getElementById("region2").style.visibility = "visible";
}
}
and it does show the right region depending on what the user inputed, but when the page loads, all the fields show up until the user click on the location field, here is the code for that so you can test it out: Code: <tr><td>Location: </td><td><select name="location" onclick="toggleTable(this);">
<option value="none">Please Select One</option>
<option value="uk">UK</option>
<option value="usa">USA</option>
</select></td></tr>
<tr id="region1"><td>Region: </td><td>
<select name="region">
<option value="uk1">uk1</option>
<option value="uk2">uk2</option>
</select></td></tr>
<tr id="region2"><td>Region: </td><td>
<select name="region">
<option value="usa1">usa1</option>
<option value="usa2">usa2</option>
</select>
</td></tr>
Any help at all please? This is the weirdest thing I've come across in awhile. I have some code that formats a input field for a date format. This code runs fine on all browser when the form tag isn't wrapped around the inputs. The second I wrap the form tag around the inputs everything messes up. The Javascript error I'm getting is "Object doesn't support this property or method." on line 45 which is the line of the date input field. I'm totally clueless what I'm doing wrong here. And so I'll leave it up to you the wonderful community to give me some help.

Is it possible to use JavaScript to send a HTML FORM this way? (By the way, this is a huge guess - I don't know JavaScript very well) Code: <SCRIPT type="text/javascript">
function Cart1Function() {
get.INPUT.quantity.value
send.to.formsubmit1.php
}
function Cart2Function() {
get.INPUT.quantity.value
send.to.formsubmit2.php
}
</SCRIPT>
<FORM action="?" method="post" name="form">
<DIV>
<INPUT type="text" name="quanitity">
<INPUT type="submit" value="CART 1" onClick="Cart1Function">
<INPUT type="submit" value="CART 2" onClick="Cart2Function">
<DIV>
</FORM>
I want to make two forms sharing the same input (quantity). I am not familiar with javascript only html, but I have researched this problem and found some solutions, but I am unsure what to do with them. I have an html checkbox form that lists book titles. The user will click on the checkbox next to the titles that interest them. Then when they click submit, I want a pop-up box to appear with the titles they selected in a printable list. I found this javascript code: Code: <script langauge="javascript" type="text/javascript">
function openPreview() {
var myWin = window.open ("popup.htm","myWindowName","width=500,height=350");
myWin.focus();
}
</script>
Then here is my html form code: Code: <form action="" form id= "myInput">
<table width="523">
<tr><td width="33"> <input type="checkbox" name="product" value="Ironman"></td>
<td width="229"><div align="left">Ironman</div></td>
<td width="174">Chris Crutcher </td>
<td width="56" align="right"> </td></tr>
<tr><td><input type="checkbox" name="product" value="Staying Fat for Sarah Byrnes">
<th><div align="left">Staying Fat for Sarah Byrnes </div></th>
<td>Chris Crutcher </td>
<td align="right"><tt>Realism</tt></td>
</tr>
<tr><td><input type="checkbox" name="product" value="The Watsons Go to Birmingham">
<th><div align="left">The Watsons Go to Birmingham </div></th>
<td>Chrisopher Paul Curtis </td>
<td align="right"> </td>
</tr>
</table>
<input type="button" id="btnPreview" name="btnPreview" value="Preview" onclick="openPreview()" />
</form>
Then on the popup.htm page I have this code Code: <script language="javascript" type="text/javascript">
document.write(window.opener.document.getElementById("myInput").value);
</script>
This code has worked for me when the form is a textarea or a label, but I don't know how to use it with a checkbox form. I know that labeling the form "my input" only works for textarea or labels, so I understand why the pop-up menu says undefined. What do I need to do to get the checkbox data to appear. |
