Javascript For Displaying Time

This JavaScript allows you to display the time of your computer:

<html>
<script language=”Javascript”>
setInterval(“settime()”, 1000);

function settime () {
var curtime = new Date();
var curhour = curtime.getHours();
var curmin = curtime.getMinutes();
var cursec = curtime.getSeconds();
var time = “”;

if(curhour == 0) curhour = 12;
time = (curhour > 12 ? curhour – 12 : curhour) + “:” +
(curmin < 10 ? “0″ : “”) + curmin + “:” +
(cursec < 10 ? “0″ : “”) + cursec + ” ” +
(curhour > 12 ? “PM” : “AM”);

document.form1.clock.value = time;
}
</script>

<body>

<form name=”form1″>
<input type=”text” name=”clock” >
</form>

</body>
</html>

Disable Or Enable Javascript

Sometimes for some reason you need to disable or enable javascript. If you’re adding JavaScript to your pages, it’s a good idea to view your pages with JavaScript disabled, so you can get an idea what users without JavaScript enabled browsers would see. Or you will have to enable javascript in order not to loose some of the web page functionality.
Here are the step-by-step instructions for majority of the browsers:

Internet Explorer

Select ‘Tools’ from the top menu
Choose ‘Internet Options’
Click on the ‘Security’ tab
Click on ‘Custom Level’
Scroll down until you see section labled ‘Scripting’
Under ‘Active Scripting’, select ‘Enable’ and click OK

Mozilla Firefox

Select ‘Tools’ from the top menu
Choose ‘Options’
Choose ‘Content’ from the top navigation
Select the checkbox next to ‘Enable JavaScript’ and click OK

Apple Safari

Select ‘Safari’ from the top menu
Choose ‘Preferences’
Choose ‘Security’
Select the checkbox next to ‘Enable JavaScript’

Upgrading your browser or installing new security software or security patches may affect your settings.
