Creating A LED To Trigger An Alarm?
Jul 6, 2011
I'm looking to create an LED like this:
in Javascript. I didn't know if this was possible at all. I have an program written in C that starts an agent and updates an XML file with data. I wanted to turn the LED on when the alarm was running, and have it off when the alarm was not running. I tried searching "LED in Javascript" but nothing came up. The image above is a LED created in a program called Labview, which I use frequently. I just trying to figure out how exactly to create one in Javascript.

How can I change the behavior of the alarm clock script from Javascript Kit located here [url] to make it so that it displays a simple alert message instead of following a link?

This script counts up, counts down and incorperates an alarm clock!
<html>
<head>
<script type="text/javascript">
var hv;
var mv;
var sv;
var timer;
var timer2;
function set(){
hv=document.getElementById("h").value*1;
mv=document.getElementById("m").value*1;
sv=document.getElementById("s").value*1;
}
function countup(){
if(sv!=59){
sv++
}
else if(mv!=59){
mv++
sv=0;
}
else if(hv!=59){
hv++
mv=0;
sv=0;
}
else{
alert("Finished counting up!")
clearTimeout(timer);
}
if(sv<10){
sv2="0"+sv;
}
else{sv2=sv}
if(mv<10){
mv2="0"+mv;
}
else{mv2=mv}
if(hv<10){
hv2="0"+hv;
}
else{hv2=hv}
document.getElementById("h").value=hv2;

sv=59;
}
else{
alert("Finished counting down!")
clearTimeout(timer2);
}
if(sv<10){
sv2="0"+sv;

}
else{mv2=mv}
if(hv<10){
hv2="0"+hv;
}
else{hv2=hv}
document.getElementById("h").value=hv2;
document.getElementById("m").value=mv2;
document.getElementById("s").value=sv2;
}
function thetime(){
var d=new Date();
var hours=d.getHours();
var mins=d.getMinutes();
var secs=d.getSeconds();
if(hours<10){
hours="0"+hours;
}
if(mins<10){
mins="0"+mins;

if(secs<10){
secs="0"+secs;
}
document.getElementById("times").value=hours+":"+mins+":"+secs;
if(timer==true && hours==hv && mins==mv && secs==sv){
alert("Alarm ringing!")
}
}
function alarmonoff(){

timer=true;
document.getElementById("alarmbut").value="Turn alarm off/set";
}
else{
timer=false;
document.getElementById("alarmbut").value="Turn alarm on/set";
}
}
</script>
</head>
<body onload="setInterval('thetime()',500)">
<table border="0">
<tr>
<td colspan="2"><input value="00" size="2" id="h">:<input value="00" size="2" id="m">:<input value="00" size="2" id="s"></td>

</tr>
<tr>
<td colspan="2"><input type="button" value="Turn alarm on/set" onclick="set(); alarmonoff()" id="alarmbut"></td>

I recently implemented the Image Cross Fade Transition [URL] add to the code to enhance the functionality. Currently, if I hover over the image, it runs the cross fade transition, which I would like to keep. I have another div on the page that I would like to trigger the first instance when hovered over as well. Is there a good way to add this? Here's what I'm using for the first instance:

My requirement was to generate a popup once you immediately login. windows.alert('please call') then the popup should come for every 2 hrs.
Even though you navigate to different pages on the site..This should still come..
I have started something like this:-- 1. Calling this script on everypage.
Code:
<script type="text/javascript">alert_settimer();</script><script type="text/javascript">
alert_settimer();
[Code]....
It is able to give me a popup for every 2 hrs. But whenever the user reloads the page after 1 hr. The function is called again and the count starts from 0hrs again. OR for example if 20 mins already passed then if i am going to a new page then the function is called again and so the timer starts again. I am not getting any idea how to restrict it calling every time. OR send that 1 hr again to the function so that it starts from there. I tried some thing like setting the value in a session variable and then starting the counter from that value.

I have a disabled field which can be changed by using search help showing the select option. After the user selects his wish, the disabled field contains his selection. I need to trigger an event automatically right after the disabled field is changed. This function triggers the event I need:
BBPSCForm_Submit('SC_REFRESH')
the code at the disabled field looks like this:
<input type=text title="`#GL_ACC`" name="`T_SCREEN_ACCLIST-G_L_ACCT[j].name`" value="`T_SCREEN_ACCLIST-G_L_ACCT[j].value`" maxlength="64" size="11" disabled>

I have a little popup window I'm making. I'd like the window to just destroy itself if the user clicks on the original, calling page.
This is what I tried in the header section of the popup page but the code is not being triggered:
<script type="text/javascript"> <!--
window.
-->
</script>
And by the way I already tried this in the body tag:
And the body tag thing actually DID close the window if the user clicked on the original calling page. BUT the window also closed if the user clicked on a combo box on the popup (because the body lost the focus), and that was not good..

I'm trying to trigger a click on an A tag from JavaScript. I'd like this to trigger any JavaScript events that might be attached. It looks like Internet Explorer and Opera support a click() function on the link, but FireFox and Safari don't. Does anyone know how I can make this work?

I have a main page that opens a pop up window when the user clicks a
link. The pop up window is a menu and when the user clicks the item, it
populates a form input element on the 'parent' window.
My question is: this new populated form element is the value that I use
to change a style.
onchange does not watch this form element because of getelementbyid, so
it doesn't trigger the function needed to change the style. onchange
works fine if I just manually input a value into the text box.
Any other way to fire the function off when the user picks their
selection from the pop-up window? I was thinking I could use
window.opener.function()? But how do I pass the form from the parent
window? From the pop up window, I don't use this.form, what do I
use?something like window.opener.form[0] ?
