$ interval没有运行，angularjs [英] $interval not running, angularjs

问题描述

我不确定为什么这段代码没有运行.我正在尝试建立一个简单的计数器，该计数器使用角度$ interval包装器每秒增加一次.

I'm not sure why this code isn't running. I'm trying to set up a simple counter that increases every second using angulars $interval wrapper.

angular.module('app').controller('testController', function($scope, $interval){
  var set_counter = function(){
    var start_time = new Date(2014, 09, 02, 0,0,0,0).getTime()
    var time_counter = new Date().getTime()
    $scope.counter = Math.ceil(time_counter / 1000000 + ((time_counter / 1000 - start_time / 1000) * 0.5)).toLocaleString();
    console.log($scope.counter);
  }
  $interval(set_counter(), 1000);
});

推荐答案

问题出在那一行

$interval(set_counter(), 1000);

您正在立即调用"set_counter"，而不是将其传递给"$ interval"作为回调.

you are calling the "set_counter" right away not passing it to "$interval" as a callback.

修复:

$interval(set_counter, 1000);
