How to print HTML content on click of a button, but not the page? [duplicate]

Answer 1

I came across another elegant solution for this:

Place your printable part inside a div with an id like this:

      
Print me

Now let's create a really simple javascript:

function printDiv(divName) {
     var printContents = document.getElementById(divName).innerHTML;
     var originalContents = document.body.innerHTML;

     document.body.innerHTML = printContents;

     window.print();

     document.body.innerHTML = originalContents;
}
