角形重设误差
角形重设误差
提问于 2014-09-24 10:50:29
我试着用angularjs做一份带有验证的表单，到目前为止我做得很好。但是，当我提交我的重置按钮时，除了我从验证部分得到的错误消息之外，所有字段都会重置。当我重置我的表单时，我如何摆脱所有的字段和错误信息。
当我按下重置按钮时就是这样的。
这是我的密码
<div class="page-header"><center><h2>Give us your Feedback</h2></center></div>
<!-- pass in the variable if our form is valid or invalid -->
<form name="userForm" ng-submit="submitForm(userForm.$valid)" novalidate>
<!-- NAME -->
<div class="form-group" ng-class="{ 'has-error' : userForm.name.$invalid && !userForm.name.$dirty }">

.controller('ContactCtrl', function($scope,$state,$ionicPopup, $timeout) {

$state.go('app.sfeedback');
};
$scope.submitForm = function(isValid) {
$scope.submitted = true;
// check to make sure the form is completely valid
if (!isValid) {
var alertPopup = $ionicPopup.alert({
title: 'Invalid data entered!',

} else {
var alertPopup = $ionicPopup.alert({

$scope.reset = function() {

$scope.user= angular.copy(original)
$scope.userForm.$setPristine()

var original = $scope.user;重置时：
$scope.user= angular.copy(original);
$scope.userForm.$setPristine();删除
type='reset' in <button>这是形状控制器的角度文档。

FormController上有API文档。
这使我发现还有其他方法可以调用，例如：
$setUntouched() --这是我使用的一个函数，如果用户将注意力集中在这个字段上，然后离开该字段，那么在运行它时，它会清除这个功能。
我创建了一个简单的表单重置函数，您也可以使用它。
// Set the following in your controller for the form/page.
// Allows you to set default form values on fields.
$scope.defaultFormData = { username : 'Bob'}
// Save a copy of the defaultFormData
$scope.resetCopy = angular.copy($scope.defaultFormData);
// Create a method to reset the form back to it's original state.
$scope.resetForm = function() {
// Set the field values back to the original default values
$scope.defaultFormData = angular.copy($scope.resetCopy);
$scope.myForm.$setPristine();
$scope.myForm.$setValidity();
$scope.myForm.$setUntouched();
// in my case I had to call $apply to refresh the page, you may also need this.
$scope.$apply();
}在您的表单中，这个简单的设置将允许您重置窗体。
<form ng-submit="doSomethingOnSubmit()" name="myForm">
<input type="text" name="username" ng-model="username" ng-required />
<input type="password" name="password" ng-model="password" ng-required />
<button type="button" ng-click="resetForm()">Reset</button>
<button type="submit">Log In</button>
