angular.js - ionic1 how to close the page

Question

I made a form with save and cancel buttons in it
How can I click the cancel button to completely close the page? I don’t want to use $state.go or $ionicHistory.goBack().
The effect I want is to restore the form to its original state after exiting. How can ionic achieve this?

This has nothing to do with ionic

If the data before modification of your form is obtained from the interface, you can re-query the interface and assign it to the Model

If you want to reduce the pressure on the request interface, cache the original query value, such as

$scope.model=resp.data;
$scope.modelTmp=resp.data;

Bind $scope.model on DOM
Submit the data when you click save, and

$scope.modelTmp=$scope.model

Cancel directly

$scope.model=$scope.modelTmp
