How to print React component on click of a button?

Question

How can I print only one component on click of a button.

I know this solution:

window.frames[\"print_frame\"].window.focus();
window.frames[\"print         


        

Answer 1

There is kind of two solutions on the client. One is with frames like you posted. You can use an iframe though:

var content = document.getElementById("divcontents");
var pri = document.getElementById("ifmcontentstoprint").contentWindow;
pri.document.open();
pri.document.write(content.innerHTML);
pri.document.close();
pri.focus();
pri.print();

This expects this html to exist

The other solution is to use the media selector and on the media="print" styles hide everything you don't want to print.

Last way requires some work on the server. You can send all the HTML+CSS to the server and use one of many components to generate a printable document like PDF. I've tried setups doing this with PhantomJs.
