提问by user1795352
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.

This should do it:
这应该这样做：
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();

var popup = window.open('message.html',"'" + name + "'",'height=300,width=300,location=no,resizable=yes,scrollbars=yes');
var element = document.createElement('div');
element.setAttribute('id', 'mydiv');
element.appendChild(document.createTextNode('blah blah'));
popup.window.onload = function() {
var win = popup.document.body;
win.appendChild(element);
var el = popup.window.document.getElementById('mydiv').innerHTML;
alert(el); //tested - ouputs 'blah blah'
};
