<div ng-controller="myCtrl">
    <form name="myForm">
        <input type="text" name="name" ng-model="myForm.name" required />
        <small class="error" ng-show="myForm.name.$error.required">Please input name...</small>
    </form>
</div>

function myCtrl($timeout) {
    //如何在此处访问myForm?
    $timeout(function() {
        console.log($scope.myForm);//undefined
    })
}

看了angular权威编程里面说表单的属性可在其所属的作用域内被访问到，但是实际上作用域内访问表单为undefined，求问如何才能访问表单(除了将表单名称以参数方式传入之外)？
