<body ng-app="aj"> <form id="form1" name="f" runat="server" ng-controller="user" ng-submit="sub(user)" > <img ng-src="{{user.head}}" ng-class="{'img':user.headbool}" /><br /><br /> <input type="text" placeholder="用户名" ng-model="user.name" /><br /><br /> <input type="text" placeholder="密码" ng-model="user.pwd" required /><br /><br /> 年龄： <select ng-model="user.age"> <option value="">请选择</option> <option ng-selected="user.age=='1'" value="1" >10</option> <option ng-selected="user.age=='2'" value="2" >20</option> </select><br /><br /> 性别：<input type="radio" ng-model="user.sex" ng-checked="user.sex=='1'" value="1" />男 <input type="radio" ng-model="user.sex" ng-checked="user.sex=='0'" value="0" />女<br /><br /> 爱好：<br /><br /> <input type="checkbox" ng-checked="check(1)" value="1" ng-model="user.like" ng-true-value="1" />篮球 <input type="checkbox" ng-checked="check(2)" value="2" ng-model="user.like" ng-true-value="2"/>足球 <input type="checkbox" ng-checked="check(3)" value="3" ng-model="user.like" ng-true-value="3"/>排球 <br /><br /> <input type="submit" value="提交" ng-disabled="f.$invalid"/> </form> </body>
当带有 ng-disabled="f.$invalid" 时(f为form的name)，input内加入required，表示这项为必填项 ！！
JS中：
angular.module('aj', []) .controller('user', function ($scope) { $scope.user = { name: "", pwd:"", headbool: true, head:'img/4.jpg', sex: '0', age: '1', like:[1,2,3] } $scope.check = function (n) { isok = false; for (x in $scope.user.like) { if ($scope.user.like[x] == n) isok = true; } return isok; } $scope.sub = function (u) { alert(u); } })
