very simple question about function in javascript

**ketav** · 06-20-2009 06:53 AM

This code works like charm on my browser as it should work

Code:

 <html>
 <script language=javascript>
 function change()
 {
 var da=new Date();
 document.getElementById("date").innerHTML=da; 
 setTimeout("change()",1000);
 } 
  </script>
 <body onLoad = "change()">
 <div id="date"></div>
 </body>
 </html>

but when i change the code to this no change in time and date

Code:

 <html>
 <script language=javascript>
 function change()
 {
 var da=new Date();
 document.getElementById("date").innerHTML=da; 
 change();
 } 
  </script>
 <body onLoad = "change()">
 <div id="date"></div>
 </body>
 </html>

as per my c lanuage experience the function change keeps calling itself creating a sort of infinite loop and keep updating date but it is not happening;

JavaScript works too closely with the browser. The changes are happening but so quickly that the browser is waiting for everything to settle down so it can display the final results. You have to give it a delay.

OK That is why it hangs when it encounters an infinite loop!!
thnx for such a fast reply

It's not really hanging up, the script is still running. The browser is just waiting for the script to get to the point.
