Question

以下是我的一个js

var ruleField = [
{
    id: "T1",
      datastore: "",
      table: "SENSORS",
      columns: ["SNS_ID","HOST_ID","SESSION_ID"],
      tableHeaders: ["SNS ID","HOST ID","SESSION ID"]
}
];

在另一个js我需要访问下拉选项中的列数组

 <select name="child.KEY_NAME" ng-if="child.KEY_NAME != 'Host' && child.KEY_NAME != 'Sensor' && child.KEY_NAME != 'Operator' && child.KEY_NAME != 'Value'" class="form-control" ng-model="temp.condition[$index][child.KEY_NAME]"" ng-disabled="readonly" ng-change="selectedOption1(selectAction);displayActionParam()">
     <option ng-repeat="field in ruleField.columns track by $index" value= "{{ field }}" >{{ field }}</option>
 </select>

Answer 1

您必须将var ruleField分配给$scope变量才能在角度指令中使用，只需添加以下行即可。

 $scope.ruleField = angular.copy(ruleField);

将ng-repeat中的表达式更改为ng-repeat="field in ruleField[0].columns track by $index"

var app = angular.module('app',[]);
app.controller('Ctrl',function($scope,$filter){


var ruleField = [
{
    id: "T1",
      datastore: "",
      table: "SENSORS",
      columns: ["SNS_ID","HOST_ID","SESSION_ID"],
      tableHeaders: ["SNS ID","HOST ID","SESSION ID"]
}
];
  
  $scope.ruleField = angular.copy(ruleField);
  });

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="app" ng-controller="Ctrl">
<select name="child.KEY_NAME"  class="form-control" ng-model="temp.condition[$index][child.KEY_NAME]" ng-disabled="readonly" ng-change="selectedOption1(selectAction);displayActionParam()">
    <option ng-repeat="field in ruleField[0].columns track by $index" value= "{{ field }}" >{{ field }}</option>
    </select>
                                                                                       
                                                                                       </div>

Answer 2

如果您添加第一个带有<script>标记 BEFORE 的角色代码（指令，控制器等）的JS文件，ruleField向量应该可以从任何脚本访问，正如@ Adrian Brand所说，你必须从它的索引访问数组，在这种情况下ruleField[0].columns，一旦这些事情完成，你应该能够使用它并操纵它。

需要访问从一个js到另一个js的数组
