updataOn 指定ng-model以什么绑定事件触发

default 就是默认的大家都知道
blur 失去焦点的时候更新
mouseover 鼠标滑过
.......

<input type="text" ng-model="name" ng-model-options="{updateOn: ‘blur‘}"><p>Hello{{name}}</p>

debounce 延迟更新

debounce 以毫秒为单位

<input type="text" ng-model="name" ng-model-options="{debounce: 1000}"><p>Hello{{name}}</p>

它的用法，其实很多比如再搜索的时候，当用户实时输入，数据模型更新，会频繁向后端请求。通过延迟更新模型，大大提高性能。

allowInvalid 是否需要验证后绑定数据 （此处就可以解决刚刚我遇到的问题）

allowInvalid 默认值为false

<input type="email" ng-model="name" ng-model-options="{allowInvalid: true}"><p>Hello{{name}}</p>

getterSetter 是否绑定到getters/setters函数上

其实 不是很懂这个用法
getterSetter默认值为 false

如果不绑定 ngModelOptions

<div ng-controller="myController"><form name="userForm">
        Name: <input Type="text" name="userName"                     ng-model="user.name"/></form><pre>user.name = <span ng-bind="user.name()"></span></pre></div><script type="text/javascript">var m1 = angular.module(‘app‘, []);m1.controller(‘myController‘, [‘$scope‘, function ($scope) {var _name = ‘MAYUFO‘;$scope.user = {name: function (newNAME) {return angular.isDefined(newNAME) ? (_name = newNAME) : _name;}}}]);</script>

结果

如果使用了ngModelOptions

<div ng-controller="myController"><form name="userForm">
        Name: <input Type="text" name="userName"                     ng-model="user.name"                     ng-model-options="{ getterSetter: true }"/></form><pre>user.name = <span ng-bind="user.name()"></span></pre></div><script type="text/javascript">var m1 = angular.module(‘app‘, []);m1.controller(‘myController‘, [‘$scope‘, function ($scope) {var _name = ‘MAYUFO‘;$scope.user = {name: function (newNAME) {return angular.isDefined(newNAME) ? (_name = newNAME) : _name;}}}]);</script>

结果

timezone

主要用在<input type =‘day‘> <input type=‘time‘>中，可以指定时区utc或者直接输入时差+0430

<input type="date" ng-model="$ctrl.date" ng-model-options="{timezone: ‘+0430‘}"><p ng-bind="$ctrl.date"></p><input type="date" ng-model="$ctrl.datea" ><p ng-bind="$ctrl.datea"></p>

$rollbackViewValue 同步模型和视图

resetWithRollback(e) {if (e.keyCode === 27) {this.myForm1.myInput1.$rollbackViewValue();}}

<form role="form" name="$ctrl.myForm1" ng-model-options="{ updateOn: ‘blur‘ }"><input type="name" name="myInput1" ng-model="$ctrl.view1" ng-keydown="$ctrl.resetWithRollback($event)"></form><p>{{$ctrl.view1}}</p>
