How reset form and validation after submitting form (AngularJS)
提问by Telary
I want to reset form and all validation messages after submitting a form. Here is plunker:http://plnkr.co/edit/992RP8gemIjgc3KxzLvQ?p=preview
我想在提交表单后重置表单和所有验证消息。这是plunker：http://plnkr.co/edit/992RP8gemIjgc3KxzLvQ? p=preview
My code is bellow:
我的代码如下：
Controller:
控制器：
app.controller('MainCtrl', function($scope) {
$scope.data={fullName:''};
$scope.submit=function(){
console.log('submit')
$scope.myForm.$setPristine();
$scope.myForm.$setUntouched();
$scope.data={fullName:''};
}
});
HTML:
HTML：
<body ng-controller="MainCtrl">
<form name="myForm" novalidate>
<div>
<label class="control-label">Name</label>
<input
name="full_name"
type="text"
ng-model="data.fullName"
ng-required="true">
<p ng-if="myForm.$submitted && myForm.$invalid">Validation message</p>
</div>
<button ng-click="submit()" type="submit">
Submit
</button>
</form>
</body>
My problem is: when user enters name in the input and clicks on Submit button, validation message shouldn't be shown, because model, form and validation should be resetted. How I can do it?
我的问题是：当用户在输入中输入名称并点击提交按钮时，不应显示验证消息，因为模型、表单和验证应该被重置。我该怎么做？
I tried to use $setPristine() and $setUntouched(), but it doesn't work for me.
我尝试使用 $setPristine() 和 $setUntouched()，但它对我不起作用。
Is it possible to do in AngularJS? Thanks!

I'm surrpised but $setpristine()doesn't update $submitted.
我很惊讶，但$setpristine()没有更新$submitted。
This may not be the prettiest solution but seems to work:
这可能不是最漂亮的解决方案，但似乎有效：
app.controller('MainCtrl', function($scope, $timeout) {
$scope.data = {
fullName: ''
};
$scope.submit = function() {
console.log('submit')
$scope.data = {
fullName: ''
};
$timeout(function() {
$scope.myForm.$setPristine();
$scope.myForm.$setUntouched();
$scope.myForm.$submitted = false;
});
}
});
