Interval function in javascript

Question

When i am using interval function, clearinterval not works properly.

 

EXAMPLE:

 

function pageload()

{ 

var url="../webapplication1/default.aspx"; 

var fininterval=intervla(Redirect,1000,url);

 }

 

function Redirect()

{

  if(okclick==true) 

   {

      clearinterval(fininterval);

      location.href= url;

   } 

   

} 

 

when the okclick becomes true then the clearinterval function not clears the interval,

the Redirect function executes n times again.
