我有一个模态引导程序，内部调用是$http用 Angular 进行的。但只有在加载页面到服务器并检索数据时，问题是：

每次打开引导模式时是否可以调用“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 ) {

		}

	$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 ) {

下面是简单的“尽可能少的更改”的答案：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（更正确）的答案将包括：

  • 可能会一起从您的项目中删除 jquery，因为 angular 和 jquery 真的不能很好地结合在一起。

  • ng-controller="DataCtrl" ng-repeat="item in numbers"执行此操作时，您会为每个“项目”获得一个 DataCtrl 实例。通常使用角度和模态，您只需要一个模态并在显示和隐藏时更改内容。（无论如何，当您的应用程序很小时。）

  • 通过使用按钮循环遍历每列的数字，您使事情变得有点干燥。我可能会更进一步，为“主题按钮”创建一个指令（因为这里的代码在每个按钮中几乎相同）。并循环遍历每一行。

  • 也许看看UI Bootstrap。但随着时间的推移，您可能会发现 angular 模式的快速修复是跳过所有其他依赖项，只使用类似ng-class="'show-modal':showModal". Bootstrap-scripts、data-toggles 和 jquery 只是将层添加到已经非常简单的东西上，直接使用 angular/css。
