angularjs - ng-submit 在表单提交后给出旧值

Question

我是 angularjs 新手，ng-submit 在表单提交后给出旧值

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.myTxt = "You have not yet clicked submit";
  $scope.sidebarname = "Vendor";
  $scope.myFunc = function () {
      $scope.myTxt = "You clicked submit!";
      alert($scope.sidebarname);
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">

<form ng-submit="myFunc()">
  <input ng-value="sidebarname" type="text">
  <input  type="submit">
</form>

<p>{{myTxt}}</p>



</div>

表单提交后 $scope.sidebarname 给出旧值 Vendor ，我已阅读并搜索它，但没有任何帮助。

任何帮助或建议都会有帮助

Answer 1

尝试:

<form ng-submit="myFunc()">
  <input ng-model="sidebarname" type="text">
  <input  type="submit">
</form>

注意:ng-model 是 different来自 ng-value
