addEventListener only works on last object

How can I get it to work for all the boxes? <html> <head> </head> <body> <script type="text/javascript"> function otherboxclick(e){ alert("other clicked"); } function color_toggle_box(boxid, color, width, height, xpos, ypos) { this.boxid = boxid; document.body.innerHTML += "<div id='" + boxid + "'; '; style=

Do properties/methods in classes take space in memory?

The same for this: public class Enemy { private int hp; public int Hp { get { return hp; } set { hp = value; } } } From what I know, a

I don't want to reinvent a wheel (or use this or this). Is there something undocumented like angular.create(path_str) ? 回答1: One way you can achieve is by using $parse service. It has getter and setter function that
