MVC4缺少登录弹出窗口(MVC4 missing login popup)

 您可以通过以下方式更改指令，为当前数据添加新参数。 添加两个手表，您将确保每次从外部更改数据时，将刷新图表以设置正确的数据，并且在选项上第一个监视时，您将确保在实际加载选项时实例化图表： 
 
.directive('mapChart', function(){
  return {
    restrict: "E",
    replace: true,        
    template: "<div id='map' class='div_content-holder'></div>",   
    scope:{
      options:"=",
      current: "=" // your actual data        
    },        
    link: function(scope, element){
      var chartexample = {};       
      scope.$watch('options', function() {
        chartexample = Highcharts.mapChart(element[0], scope.options);
      });
      scope.$watch('current', function(){
        chartexample.series[0].setData(scope.current);
      });            
    }
  }
});
 
 你可以摆脱两个观察者。 关于init，您必须确保在已经拥有所有选项后初始化您的指令，因此您不再需要关于选项的监视。 关于当前数据，您可以在指令中添加一个回调参数& ，它将更新图表的值，并在与控制器内部选择的ngChange相关联的函数内调用该指令的回调。 
 
 这将使代码更好，更清洁。 但是现在你可以这样享受你的图表:) 
 
 祝你的应用好运！ 
 
 干杯:) 

You can change your directive in the following way, adding a new parameter for the current data. Adding the two watches you will ensure that every time you change data from outside, the chart will be refreshed setting up the correct data and with the first watch on the option you will ensure to instantiate the chart when your options have really been loaded:
 
.directive('mapChart', function(){
  return {
    restrict: "E",
    replace: true,        
    template: "<div id='map' class='div_content-holder'></div>",   
    scope:{
      options:"=",
      current: "=" // your actual data        
    },        
    link: function(scope, element){
      var chartexample = {};       
      scope.$watch('options', function() {
        chartexample = Highcharts.mapChart(element[0], scope.options);
      });
      scope.$watch('current', function(){
        chartexample.series[0].setData(scope.current);
      });            
    }
  }
});
 
You can get rid of both the watchers. About the init, you just have to be sure to init your directive once you have already all your options, so you don't need anymore the watch on the options. About the current data, you can add a callback parameter & in the directive which will update the values of the chart, and call this callback of the directive inside the function associated to the ngChange of the select inside the controller.
 
This will make the code better and cleaner. But for now you can enjoy your chart in this way :) 
 
My best luck for your app! 
 
Cheers :)
