Print only?

Question

How do I print the indicated div (without manually disabling all other content on the page)?

I want to avoid a new preview dialog, so creating a new window with this

Answer 1

The printDiv() function came out a few times, but in that case, you loose all your binding elements and input values. So, my solution is to create a div for everything called "body_allin" and another one outside the first one called "body_print".

Then you call this function:

function printDiv(divName){

    var printContents = document.getElementById(divName).innerHTML;

    document.getElementById("body_print").innerHTML = printContents;

    document.getElementById("body_allin").style.display = "none";
    document.getElementById("body_print").style.display = "";

    window.print();

    document.getElementById("body_print").innerHTML = "";
    document.getElementById("body_allin").style.display = "";
    document.getElementById("body_print").style.display = "none";

}
