Question

单击保存按钮时，我试图显示网格中文本框和按钮的值。我写了html部分，我自己尝试了一些东西。单击保存按钮时，值不会显示在表格中。

<!DOCTYPE html>
<html>

    <title>Header Details</title>

Answer 1

问题很少，

（i）两个div只有一个ng-app和ng-controller共同

（ii）您的代码没有角度参考

（iii）您需要在保存功能

上将值推送到数组

 $scope.headerData.Result.push({
       "Header": $scope.header,
       "Status": $scope.status
     });

<强>样本

var app = angular.module('myApp', []);
 app.controller('headerCtrl', function($scope) {
   $scope.headerData = {};
   $scope.headerData.Result = [];
   $scope.clear = function(){
      $scope.headerData.Result = [];
   }
   $scope.Save = function() {
     $scope.headerData.Result.push({
       "Header": $scope.header,
       "Status": $scope.status

     });

   };
 });

您的代码中存在许多问题。

没有Angular文件。请根据您的版本添加角度文件。您已经定义了两个控制器中的一个，清除，未定义。你已经在两个地方宣布了ng-app =“myApp”，这是一个非常糟糕的做法。您在范围内使用没有引号的结果。它是一个json对象，很适合使用键值的引号。

我已经纠正了所有错误，以下是您的最终代码。在复制之前，请完成更改并理解它们。

<div class="container" ng-app="myApp" ng-controller="headerCtrl">
