带过滤器的覆盖值Angularjs ngInit [英] Angularjs ngInit with filter override values

问题描述

我想初始化没有成功滤波值。我将使用部分/ NG-包括使变量的名称不能改变。

I trying to init a filtered value without success. I'll use partial/ng-include so variable's name can't change.

我使用angularjs V1.0.2，我也试图与V1.1.1

I using angularjs v1.0.2 and I tried also with v1.1.1

<script>
    function Ctrl($scope) {
      $scope.trains = [ 1, 2];
    }
</script>


<div ng-app ng-controller="Ctrl">
  <div ng-init="t = (trains | filter:1)">    
    {{ t }}
    {{ trains | filter:1 }}
  </div>
  <div ng-init="t = (trains | filter:2)">
    {{ t }}
    {{ trains | filter:2 }}
  </div>
</div>

输出

[2] [1]
[2] [2]

推荐答案

不知道这是你想要的...
但是你可以以NG-init和组合之间使用指令NG-包括：

Not sure this is what you want... But you can use directive in order to combine between ng-init and ng-include:

HTML

<div ng-app="myApp" ng-controller="Ctrl">    
    <my-directive field-name=1 train=2></my-directive>
    <my-directive field-name=2 train=17></my-directive>
</div>

JS：

function Ctrl($scope, $filter) {
  $scope.trains = [1, 2]; 
}

angular.module("myApp", [])
.directive("myDirective", function() {
    return {
        restrict: "E",
        scope: 'isolate',
        template: "<div>{{exposeAttribute}} {{anotherOne}}</div>",
        controller: Ctrl,
        //templateUrl: "mytemplate.html",
        link: function(scope, element, attr) {
            scope.exposeAttribute = attr.fieldName;
            scope.anotherOne = attr.train;
        }
    };
});

和的输出是：

1 2
