Open a blank window, write to it, and select the written text

Question

I'm trying to open a blank window with Javascript, write text to it, and then select the text that I wrote, all automatically.

I have:

var myWindow=window.open('');
myWindow.document.write("hey");
myWindow.select();

which opens the window and writes the text, but does not select it.

Answer 1

This should do it:

var myWindow=window.open('');
myWindow.document.write("<div id='hello'>hey<div>");
var range = myWindow.document.createRange();
range.selectNode(myWindow.document.getElementById('hello'));
myWindow.getSelection().addRange(range);
myWindow.select();
