    date loop

    i'm trying to get my date in increase my 1 month on a set interval but it does not work, what can I do here?

    Code:
    <script type="text/javascript">
    
    var myDate = new Date(1960,1,1);
    var myVar=setInterval(function(){myTimer()},1000);
    
    function myTimer(){
    	var nDate = new Date(myDate.getMonth()+1);
    	alert(nDate);
    
    }
    
    </script>

    Better write the output to a <span> rather than use an alert, as otherwise with one second interval you will not be able to stop it without restarting the browser.

    Code:
    <span id = "theDate"></span>
    
    <script type="text/javascript"> 
    var myDate = new Date(1960,1,1); 
    document.getElementById("theDate").innerHTML = myDate;
    setInterval(myTimer,1000) 
    
    function myTimer(){
    myDate.setMonth(myDate.getMonth()+1);
    document.getElementById("theDate").innerHTML = myDate;
    	
    }
    </script>

    All the code given in this post has been tested and is intended to address the question asked.
    Unless stated otherwise it is not just a demonstration.

    That's why there's an extra checkbox in the bottom of the alert in some browsers - so you can stop the constant debugging alerts from popping up without having to restart the browser.

    Don't forget to start your JavaScript code with "use strict"; which makes it easier to find errors in your code.
