角/离子 - 控制器只运行一次 [英] Angular / Ionic - controller only runs once

问题描述

我开始接触角通过离子框架，但我不能明白为什么控制器只运行一次，也就是我改变状态，控制器的运行，切换到另一种状态，然后再次与控制器不运行第二次。这是我的状态：

I'm starting out with Angular through the Ionic Framework but I am failing to understand why the controller only runs once i.e. I change state, the controller runs, change to another state and then back again and the controller does not run a second time. This is my state:

$stateProvider.state( 'container.previous', {
    url: 'previous',
    views: {
        main : {
            templateUrl : 'views/previous.html',
            controller : function( $scope, $cordovaSQLite ){
                $scope.firms = [];
                $cordovaSQLite.execute(window.db, "SELECT * FROM recent GROUP BY phone ORDER by id DESC").then(function(res) {
                    for (i = 0; i < res.rows.length; i++) {
                        $scope.firms.push(res.rows.item(i));
                    }
                }, function (err) {
                    console.error(err);
                });
            }
        }
    },
    onStateChangeStart : function(){
        backButton = true;

    }
});

在另一种状态，如果你点击相关的坚定的按钮，这样可以节省的企业的数据到本地存储。上述状态表示其中有previously点击的公司。但我不能想出如何更新 $ scope.firms 正确的控制器永远不会再次运行。

In another state, if you click on a button related to a "firm", it saves the "firms" data to local storage. The above state shows the firms in which you have previously clicked on. But I cannot figure out how to update the $scope.firms correctly as the controller never runs again.

谁能帮我？

推荐答案

您可以把code要在$ ionicView.enter运行：

You can put the code you want to run in $ionicView.enter:

controller : function( $scope, $cordovaSQLite ){
    $scope.$on('$ionicView.enter', function() {
        // code to run each time view is entered
    });

    ...
});
