As a small problem, I got a solution! But why is this so?
var label = new Text(text.toString(), "20px Arial", "orange"); label.textAlign = "center"; label.x = 708; label.y = 435; label.maxWidth=40; stage.addChild(label);
Firstly, I did not add label.maxWidth = 40. And something surprising, wriggling, it works in firefox and chrome on Ubuntu! However, he did not display anything in chrome on the windows.
Attach the maxWidth ad from the official website http://easeljs.com/docs/Text.html
maxWidth - Number The maximum width for drawing text. If the maxWidth specified (non-empty) text is compressed or compressed, to do this, insert this width.
