javascript - Ajax isn't working on website -


for personal site want insert simple ajax server clock website, reason it's not showing in header. here's javascript code

var httpxml; try {   // firefox, opera 8.0+, safari   httpxml=new xmlhttprequest(); } catch (e) {   // internet explorer   try {     httpxml=new activexobject("msxml2.xmlhttp");   } catch (e) {     try {       httpxml=new activexobject("microsoft.xmlhttp");     } catch (e) {       alert("ur browser doesn't support ajax m8, try reinstalling windows 95");       return false;     }   }  }  function stateck() {   if(httpxml.readystate==4) {     document.getelementbyid("time").innerhtml=httpxml.responsetext;   } }  var url="ajax-server-clock-demock.php"; url=url+"?sid="+math.random(); httpxml.onreadystatechange=stateck; httpxml.open("get",url,true); httpxml.send(null); tt=timer_function(); }  function timer_function(){   var refresh=1000; // refresh rate in milli seconds   mytime=settimeout('ajaxfunction();',refresh) }

and in php file 

<?php echo date("d/m/y : h:i:s", time()); ?>

lastly in header

<time>bacon</time>

i have see more code in context because several things can make not work, in mean time, there multiple issues script, among others:

you did settimeout(). execute once, assuming want clock update every second need use:

http://www.w3schools.com/jsref/met_win_setinterval.asp

oh, also, need like: 

document.getelementsbytagname('time')[0];

instead of getelementbyid()

or add id element like:

<time id="mytime"></time>

and can call:

document.getelementbyid('mytime');

got it?

and also, declared ajaxfunction() calling in settimeout?

also, there better ways clock... , should consider using jquery or that, make life easier when doing ajax, dom manipulation , etc...
