// example
// company/edit?id=1

model.get = function (id) {
  // jquery ajax方法本来返回promise对象多方便啊
  return $.get('/api/company/'+id);
}



app.page.edit = page({
  args:{
    id:function (value) { return isInt(value).then(model.get) }
  }
},function (contextInfo,pageOp,argMap) {
  var company = argMap.id;
  alert(company.name); // company 已经过model.get返回对象了
})
