## HTML、CSS禁止选择文字
//HTML、CSS禁止选择文字，针对IE、FF、Chrome等
<div unselectable="on" style="-moz-user-select:none;-webkit-user-select:none;" onselectstart="return false;">
你选不了我,
unselectable: IE/Opera,
-moz-user-select: FireFox,
onselectstart: IE/Safari,
-webkit-user-select:Chrome
</div>

## 动态创建命名空间
var MyApp = {};

MyApp.namespace = function (name) {
  var parts = name.split('.');
  var current = MyApp;
  for (var i in parts) {
    if ( !current[ parts[i] ] ) {
      current[ parts[i] ] = {};
    }
    current = current[ parts[i] ];
