提交时重置表单 [英] Reset form on submit
问题描述
我正在提交一个表单，然后将所有字段设为空，但它不起作用.表单已成功提交，但字段未重置.我正在使用角材料进行造型.更新了控制器.
Html<表单名称="myform"><md-输入-容器><label for="name">联系人姓名</label><input type="text" md-maxlength="20" required="" md-no-asterisk name="name" ng-model="info.name" md-autofoucs><div ng-messages="myform.name.$error" role="alert"><div ng-message="required">这是必需的.</div><div ng-message="md-maxlength">名称必须少于 20 个字符.</div></md-input-container><md-输入-容器><label for="phone">电话号码</label><input type="text" name="phone" required md-no-asterisk ng-model="info.phone"><div ng-messages="myform.phone.$error"><div ng-message="required">这是必需的.</div>
</md-input-container><md-输入-容器><label for="email">电子邮件</label><input type="text" name="email" ng-model="info.email"></md-input-container><md-输入-容器><md-button class="md-primary" ng-click="saveit(info)">保存</md-button><md-button class="md-primary">取消</md-button></md-input-container></表单>**控制器中的功能**angular.module('contact', ['ui.router', 'ngMaterial', 'templates','ngMessages']).config(['$mdThemingProvider', '$stateProvider', 函数 ($mdThemingProvider, $stateProvider) {$mdThemingProvider.theme('默认').primaryPalette('蓝色').accentPalette('橙色');$stateProvider.state('家', {网址:'',templateUrl: 'templates/home.html',控制器:'MainCtrl 作为 vm'});}]).controller('MainCtrl', function ($scope, $mdSidenav,$mdDialog,$mdToast, 联系人) {var vm = 这个；$scope.searchText ="";$scope.toggleSidenav = function(){$mdSidenav('left').open();};contacts.getall().then(function(response){控制台日志(响应数据)；$scope.people = response.data;});$scope.saveit = function(detail, myform){if (!detail.name || !detail.phone) { return ;}联系人.添加({名称:detail.name，电话:详细电话，电子邮件:detail.email});$mdToast.show($mdToast.simple().content("联系人已添加！").position('顶部，右侧').hideDelay(2000));$scope.people.push(detail);$scope.info = {};$scope.myform.$setPristine();$scope.myform.$setUntouched();};$scope.showConfirm = function(ev, person) {var confirm = $mdDialog.confirm().title('你确定吗?').ariaLabel('幸运日').targetEvent(ev).ok('请删除它！').cancel('我想保留它.');$mdDialog.show(confirm).then(function() {contacts.deletethis(person.id).then(function(){$mdToast.show($mdToast.simple().content("已删除！").position('顶部，右侧').hideDelay(2000));});var index = $scope.people.indexOf(person);$scope.people.splice(index,1);}， 功能() {$scope.status = '你决定保留你的债务.';});};});
您没有正确使用 $scope 和 this 作为控制器.您可以使用 $scope 或 controller as 语法将范围与视图绑定.
我建议您在此处阅读更多相关信息.
在控制器中更新您的 saveit() 函数，如下所示:
app.controller('MainCtrl', function($scope, $mdSidenav, $mdDialog, $mdToast) {var vm = 这个；vm.info = {};//你剩下的代码vm.saveit = 函数(){//在这里做你的操作vm.info = {};};});更新您的 html 页面如下:
<表单名称="myform"><md-输入-容器><label for="name">联系人姓名</label><input type="text" ng-maxlength="20" required md-no-asterisk name="name" ng-model="vm.info.name" md-autofoucs></md-input-container><md-输入-容器><label for="phone">电话号码</label><input type="text" name="phone" required md-no-asterisk ng-model="vm.info.phone"></md-input-container><md-输入-容器><label for="email">电子邮件</label><input type="text" name="email" ng-model="vm.info.email"></md-input-container><md-输入-容器><md-button class="md-primary" ng-click="vm.saveit()">保存</md-button><md-button class="md-primary">取消</md-button></md-input-container></表单>I am submitting a form and then making all the field empty but it's not working. Form is getting submitted successfully but the fields are not getting reset. I am using angular-material for styling. Updated controller.
Html
<form name="myform">
<md-input-container>
<label for="name">Contact Name</label>
<input type="text" md-maxlength="20" required="" md-no-asterisk name="name" ng-model="info.name" md-autofoucs>
<div ng-messages="myform.name.$error" role="alert">
<div ng-message="required">This is required.</div>
<div ng-message="md-maxlength">The name has to be less than 20 characters long.</div>
</div>
</md-input-container>
<md-input-container>
<label for="phone">Phone Number</label>
<input type="text" name="phone" required md-no-asterisk ng-model="info.phone">
<div ng-messages="myform.phone.$error">
<div ng-message="required">This is required.</div>
</div>
</md-input-container>
<md-input-container>
<label for="email">Email</label>
<input type="text" name="email" ng-model="info.email">

<md-button class="md-primary" ng-click="saveit(info)">Save</md-button>
<md-button class="md-primary">Cancel</md-button>
</md-input-container>
</form>
**Function in Controller**
angular.module('contact', ['ui.router', 'ngMaterial', 'templates','ngMessages'])
.config(['$mdThemingProvider', '$stateProvider', function ($mdThemingProvider, $stateProvider) {
$mdThemingProvider.theme('default')
.primaryPalette('blue')
.accentPalette('orange');
$stateProvider
.state('home', {
url: '',
templateUrl: 'templates/home.html',
controller: 'MainCtrl as vm'
});
}]).controller('MainCtrl', function ($scope, $mdSidenav,$mdDialog,$mdToast, contacts) {
var vm = this;
$scope.searchText ="";
$scope.toggleSidenav = function(){
$mdSidenav('left').open();
};
contacts.getall().then(function(response){
console.log(response.data);
$scope.people = response.data;
});
$scope.saveit = function(detail, myform){
if (!detail.name || !detail.phone) { return ;}
contacts.add({
name: detail.name,
phone: detail.phone,
email: detail.email
});
$mdToast.show(
$mdToast.simple()
.content("ContactAdded!")
.position('top, right')
.hideDelay(2000)
);
$scope.people.push(detail);
$scope.info = {};
$scope.myform.$setPristine();
$scope.myform.$setUntouched();
};
$scope.showConfirm = function(ev, person) {
var confirm = $mdDialog.confirm()
.title('Are you sure?')
.ariaLabel('Lucky day')
.targetEvent(ev)
.ok('Please delete it!')
.cancel('I want to keep it.');
$mdDialog.show(confirm).then(function() {
contacts.deletethis(person.id).then(function(){
$mdToast.show(
$mdToast.simple()
.content("Deleted!")
.position('top, right')
.hideDelay(2000)
);
});
var index = $scope.people.indexOf(person);
$scope.people.splice(index,1);
}, function() {
$scope.status = 'You decided to keep your debt.';
});
}; });
You are not using $scope and this for controller correctly. You can use $scope or controller as syntax to bind your scope with view.
I suggest you to read more about it here.
Update your saveit() function inside controller as below:
app.controller('MainCtrl', function($scope, $mdSidenav, $mdDialog, $mdToast) {
var vm = this;
vm.info = {};
//your rest the code
vm.saveit = function() {
//do your operations here
vm.info = {};
};
});
Update your html page as below:
<div ng-controller="MainCtrl as vm">
<form name="myform">
<md-input-container>
<label for="name">Contact Name</label>
<input type="text" ng-maxlength="20" required md-no-asterisk name="name" ng-model="vm.info.name" md-autofoucs>
</md-input-container>
<md-input-container>
<label for="phone">Phone Number</label>
<input type="text" name="phone" required md-no-asterisk ng-model="vm.info.phone">
</md-input-container>
<md-input-container>
<label for="email">Email</label>
<input type="text" name="email" ng-model="vm.info.email">
</md-input-container>
<md-input-container>
<md-button class="md-primary" ng-click="vm.saveit()">Save</md-button>
<md-button class="md-primary">Cancel</md-button>
</md-input-container>
</form>
</div>
