Loading issue with iframe using Jquery

Loading issue with iframe using Jquery

Hi,

I am loading a page into an iframe using JQuery by changing the src attribute of the iframe when the user clicks a button. Is there any way to have it so that if the button is clicked again it doesn't reload the page into the ifram but just keeps it as it is?

Here is my JQuery code:

     $(document).ready(function(){

                $('.button').click(function(){
                        $('iframe.chart').attr('src', 'page.html');
                });
        });


Thanks in advance
