在尝试访问范围问题的角度，引导指令 [英] Issue in angular-bootstrap directive while trying to access scope

本文介绍了在尝试访问范围问题的角度，引导指令的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我已经使用 https://github.com/angular-ui/bootstrap 手风琴，但这个指令我有范围的问题。它仅允许如果ngController手风琴内声明的使用范围。

请访问空两Plunker链接，你就会明白我想说的：

  };
}）;


解决方案

我找到了解决办法：

我们可以从函数本身使用$范围传递的价值，没有必要访问值。

    警报（选择）;
  };
}）;

I have used https://github.com/angular-ui/bootstrap for accordion, but with this directive I'm having scope issues. It only allows to use scope if ngController is declared inside of accordion.

Please visit below two Plunker links and you will understand what I'm trying to say:

Example 1: http://plnkr.co/edit/Fb4UauWWmHOnTyjMPFBo

index.html

<!doctype html>
<html ng-app="plunker">
<head>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.js"></script>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-animate.js"></script>
  <script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.13.4.js"></script>

<body>  
  <div ng-controller="AccordionDemoCtrl">
    <accordion>
      <accordion-group is-open="status.open">
        <accordion-heading>
          Accordian - Click me <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.open, 'glyphicon-chevron-right': !status.open}"></i>
        </accordion-heading>
        <div>
          <input type="checkbox" ng-model="select" ng-click="checkAll()" /> Check me
        </div>
      </accordion-group>
    </accordion>
  </div>
</body>
</html>

script.js

var app = angular.module('plunker', ['ui.bootstrap']);
app.controller('AccordionDemoCtrl', function($scope) {
  $scope.checkAll = function() {
    alert($scope.select);
  };
});

Example 2: http://plnkr.co/edit/ljEMUnTqPBqUyub5eEB7

index.html

<!doctype html>
<html ng-app="plunker">
<head>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.js"></script>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-animate.js"></script>
  <script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.13.4.js"></script>
  <script src="script.js"></script>
  <link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
  <accordion>
    <accordion-group is-open="status.open">
      <accordion-heading>
        Accordian - Click me <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.open, 'glyphicon-chevron-right': !status.open}"></i>
      </accordion-heading>
      <div ng-controller="AccordionDemoCtrl">
        <input type="checkbox" ng-model="select" ng-click="checkAll()" /> Check me
      </div>
    </accordion-group>
  </accordion>
</body>
</html>

script.js

var app = angular.module('plunker', ['ui.bootstrap']);
app.controller('AccordionDemoCtrl', function($scope) {
  $scope.checkAll = function() {
    alert($scope.select);
  };
});

解决方案

I found the solution:

We can pass the value from the function itself, not necessary to access value using $scope.

Demo: http://plnkr.co/edit/fZZrDN4e8kbvimR2Wzya

index.html

<!doctype html>
<html ng-app="plunker">

<head>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.js"></script>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular-animate.js"></script>
  <script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.13.4.js"></script>
  <script src="script.js"></script>
  <link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
</head>

<body>

  <div ng-controller="AccordionDemoCtrl">
    <accordion>
      <accordion-group is-open="status.open">
        <accordion-heading>
          Accordian - Click me <i class="pull-right glyphicon" ng-class="{'glyphicon-chevron-down': status.open, 'glyphicon-chevron-right': !status.open}"></i>
        </accordion-heading>
        <div>
          <input type="checkbox" ng-model="select" ng-click="checkAll(select)" /> Check me
        </div>
      </accordion-group>
    </accordion>
  </div>
</body>

</html>

script.js:

var app = angular.module('plunker', ['ui.bootstrap']);
app.controller('AccordionDemoCtrl', function($scope) {
  $scope.checkAll = function (select) {
    alert(select);
  };
});
