例如在PHP中,我可以这样做：

$obj->subobject->property = 'Foo';
$property =& $obj->subobject->property;
$property =  'Bar';
echo $obj->subobject->property;
// output 'Bar'

这不是一个很好的例子,但你得到的想法.

我想在Javascript中复制此行为.我经常不得不深入对象,而且变得非常烦人：

if (please.stop.making.me[somevar].type.so.much.length) {
    please.stop.making.me[somevar].type.so.much[newSubObjectKey] = anObject;
}

// perform more operations on the object down here

这将会更容易阅读,更容易输入：

var subObj = is.much.easier.to.type.once;
if (subObj.length) {
     subObj[newSubObjectKey] = anObject;
}

// now that's much better

我知道我已经知道了,但是我只是在Javascript中进入“高级新手”.
