Question

有没有一种很好的方法来获取一组元素而不使用表单？我的问题是使用.net mvc和<fieldset name="user_fieldset"> <input type="text" ng-model="Firstname" /> <input type="text" ng-model="Lastname" /> ... </fieldset> <button ng-disabled="user_fieldset.$valid" ng-class="{'disabled' : user_fieldset.$valid}">Next</button>可以删除其中的任何形式。

DROP TABLE IF EXISTS `CUSTOMER`; 
CREATE TABLE `CUSTOMER` (   
`ACCT_ID` INT NOT NULL  , 
`FIRST_NAME` VARCHAR(10) , 
`LAST_NAME` VARCHAR(9) , 
`ADDRESS_1` VARCHAR(34) , 
`ADDRESS_2` VARCHAR(7) , 
`ADDRESS_3` VARCHAR(8) , 
`ADDRESS_4` VARCHAR(7) , 
`CONTACT` VARCHAR(14) , 
`EMAIL` VARCHAR(47) , 
`REG_DATE` DATETIME , 
`LAST_PURCHASE` DATETIME , 
PRIMARY KEY  (`ACCT_ID`) );

您可以使用ng-form指令作为属性。

来自AngularJS Hub的示例：

＆＃13;

angular.module("mainModule", [])
  .controller("mainController", function ($scope)
  {
    $scope.person = {};
  });
