If you don t care if the code within the timer may take longer than your interval  use setInterval     setInterval function  delay    That fires the function passed in as first parameter over and over   A better approach is  to use setTimeout along with a self-executing anonymous function    function           do some stuff     setTimeout arguments callee  60000           that guarantees  that the next call is not made before your code was executed  I used arguments callee in this example as function reference  It s a better way to give the function a name and call that within setTimeout because arguments callee is deprecated in ecmascript 5

You can simply call setTimeout at the end of the function  This will add it again to the event queue   You can use any kind of logic to vary the delay values   For example   function multiStep          do some work here   blah blah whatever      var newtime   60000    if   requestStop        setTimeout multiStep  newtime

A better use of jAndy s answer to implement a polling function that polls every interval seconds  and ends after timeout seconds   function pollFunc fn  timeout  interval        var startTime    new Date    getTime        interval   interval    1000        function p             fn            if    new Date  getTime   - startTime    lt   timeout                 setTimeout p  interval                          pollFunc sendHeartBeat  60000  1000     UPDATE  As per the comment  updating it for the ability of the passed function to stop the polling   function pollFunc fn  timeout  interval        var startTime    new Date    getTime        interval   interval    1000      canPoll   true        function p             canPoll     new Date  getTime   - startTime    lt   timeout          if   fn    amp  amp  canPoll        ensures the function exucutes             setTimeout p  interval                          pollFunc sendHeartBeat  60000  1000    function sendHeartBeat params                        if  receivedData               no need to execute further         return true     or false  change the IIFE inside condition accordingly
