AngularJS: API: ng/directive/input[month]

input[month]

- input in module ng

月份输入的验证和转换。目前的浏览器还不支持HTML5的日期输入控件,所以将使用文本输入。在这种情况下，输入的文本必须符合ISO-8601的月份格式(yyyy-MM)的校验规范，例如：2009-01。模型必须永远是一个Date对象。In the event the model is not set to the first of the month, the first of that model's month is assumed.

指令信息

这个指令执行优先级为0.

用法

<input Type="month"
       ng-model=""
       [name=""]
       [min=""]
       [max=""]
       [required=""]
       [ng-required=""]
       [ng-change=""]>

参数

参数	类型	详述
ngModel	string	声明用于数据绑定的Angular表达式。
name (可选)	string	发布到表单下的控件的属性名称。
min (可选)	string	当输入的值小于`min`时，设置`min` 验证错误键。 This must be a valid ISO month format (yyyy-MM).
max (可选)	string	当输入的值大于`max`时，设置`max`验证错误键。This must be a valid ISO month format (yyyy-MM).
required (可选)	string	如果未输入值就设置 `required` 验证错误键。
ngRequired (可选)	string	当ngRequired表达式等于true时，添加`required`属性和`required`验证约束到元素上。使用`ngRequired`替换`required`，当你想数据绑定到`required`属性上时。
ngChange (可选)	string	Angular表达式，当输入元素通过用户交互方式发生输入变化时会执行这个表达式。

示例

index.html

<script>
 angular.module('monthExample', [])
   .controller('DateController', ['$scope', Function($scope) {
     $scope.value = new Date(2013, 9, 1);
   }]);
</script>
<form name="myForm" ng-controller="DateController as dateCtrl">
  Pick a month int 2013:
  <input id="exampleInput" Type="month" name="input" ng-model="value"
     placeholder="yyyy-MM" min="2013-01" max="2013-12" required />
  <span class="error" ng-show="myForm.input.$error.required">
     Required!</span>
  <span class="error" ng-show="myForm.input.$error.month">
     Not a valid month!</span>
  <tt>value = {{value | date: "yyyy-MM"}}</tt><br/>
  <tt>myForm.input.$valid = {{myForm.input.$valid}}</tt><br/>
  <tt>myForm.input.$error = {{myForm.input.$error}}</tt><br/>
  <tt>myForm.$valid = {{myForm.$valid}}</tt><br/>
  <tt>myForm.$error.required = {{!!myForm.$error.required}}</tt><br/>
</form>
