不缓存或读取缓存 | AngularJS 1.6 | Bootstrap 3.3

Question

我有一个模态 Bootstrap，里面有一个调用 $http 和 Angular。但是只有在加载页面时才会去服务器并检索数据，问题是：

是否可以在每次 Bootstrap 模式打开时调用 "http"？

var helloApp = angular.module('helloApp',[]);

helloApp.controller("CompanyCtrl",['$scope',function($scope){

 $scope.numbers = [1,2,3,4,5,6,7,8,9];
 $scope.tableTitle = "SEMESTRE ";
 $scope.checked1 = false; //DELETE

 $scope.number = 7;
 $scope.getNumber = function(num) {
     return new Array(num);   
 }

 $scope.companies = [
                    { 'name':'Infosys Technologies',
                     'employees': 125000,
                     'headoffice': 'Bangalore'},
                     { 'name':'Cognizant Technologies',
                      'employees': 100000,
                      'headoffice': 'Bangalore'},
                      { 'name':'Wipro',
                       'employees': 115000,
                       'headoffice': 'Bangalore'},
                       { 'name':'Tata Consultancy Services (TCS)',
                        'employees': 150000,
                        'headoffice': 'Bangalore'},
                        { 'name':'HCL Technologies',
                         'employees': 90000,
                         'headoffice': 'Noida'},
                    ];
    $scope.vAddGroup = [

    ];

$scope.addGroup = function(name){ 
 var index = -1; 
 var comArr = eval( $scope.companies );
  for( var i = 0; i < comArr.length; i++ ) {
   if( comArr[i].name === name ) {
    index = i;
    break;
   }
  }
  if( index === -1 ) {
   alert( "Something gone wrong" );
  }

 $scope.vAddGroup.push({ 'name':comArr[index].name, 'employees':comArr[index].employees, 'headoffice':comArr[index].headoffice });
 $scope.checked1 = true;

 var d = document.getElementById("1"); // IDENTIFICADOR UNICO CADA MATERIA
 d.className = " subjectOK not-active";

};


$scope.addRow = function(){  
 $scope.companies.push({ 'name':$scope.name, 'employees': $scope.employees, 'headoffice':$scope.headoffice });
 $scope.name='';
 $scope.employees='';
 $scope.headoffice='';
};

$scope.removeRow = function(name){    
  var index = -1;  
  var comArr = eval( $scope.vAddGroup );
  for( var i = 0; i < comArr.length; i++ ) {
   if( comArr[i].name === name ) {
    index = i;
    break;
   }
  }
  if( index === -1 ) {
   alert( "Something gone wrong" );
  }
  $scope.vAddGroup.splice( index, 1 ); 
  $scope.checked1 = false;

  var d = document.getElementById("1"); // IDENTIFICADOR UNICO CADA MATERIA
  d.className = " subject";
 };

}]);



helloApp.controller('DataCtrl', function($scope, $http) {

  .then(function(response) {

Answer 1

下面是简单的 "as little changes as possible" 答案：我在您的按钮上添加了 ng-click 并将您的 http-call 包装在一个函数中，该函数在单击任何按钮时都会被调用。

更长（也更正确）的答案包括：

可能会一起从您的项目中删除 jquery，因为 angular 和 jquery 真的不能一起玩。
ng-controller="DataCtrl" ng-repeat="item in numbers" 当您这样做时，您会为每个 "item" 获得一个 DataCtrl 实例。通常使用 angular 和模态框，您只需要一个模态框并在显示和隐藏它时更改内容。（反正你的应用很小。）
您通过使用按钮循环遍历每一列的数字，让事情变得有点干涩。我可能会更进一步并为 "subject-button" 创建一个指令（因为这里的代码在每个按钮中几乎相同）。并遍历每一行。
或许可以看看 UI Bootstrap。但随着时间的推移，您可能会发现 angular 中模式的快速修复是跳过所有其他依赖项，而只使用 ng-class="'show-modal':showModal" 之类的东西。 Bootstrap-脚本、数据切换和 jquery 只是在已经非常简单的东西上添加层 angular/css.
