一, 理解Javascript的运行环境概念
function say(msg) {
alert(this + ' says ' + msg);
}
var tt = {
message: 'James ',
say: function (thing) {
alert(this.message + thing);
}
}
var ss = {
message: 'Alex ',
say: function (thing) {
alert(this.message + ' solve ' + thing);
}
}
tt.say.call(ss, "Hello World");
// output: Alex Hello World
二 JS的模块化编程规范
