When I load this in a browser it'll show the time it was when page was fully loaded, but won't update itself every second. How do I do this?
var h = date.getHours(); if(h<10) h = "0"+h;
var m = date.getMinutes(); if(m<10) m = "0"+m;
var s = date.getSeconds(); if(s<10) s = "0"+s;
document.write(h + " : " + m + " : " + s);
Use setInterval
:
setInterval(clock, 1000);
function clock() {
var date = new Date();
var h = date.getHours(); if(h<10) h = "0"+h;
var m = date.getMinutes(); if(m<10) m = "0"+m;
var s = date.getSeconds(); if(s<10) s = "0"+s;
document.write(h + " : " + m + " : " + s);
}
Although you probably want to update a HTML
element rather than document.write
to the page every second.
Wrap it up in a function and let it call itself:
everysecond=1000; // milliseconds
function showCurrentTime(){
/*do your timing stuff here */
if(someConditionIsntMet) setTimeout(showCurrentTime, everysecond)
}
