Question

我有一个按钮：

$scope.deleteCompany = function(id){
        console.log(id);
}

我也有角度函数：

当我在确认控制台输出时点击取消时：

当我在确认控制台输出时单击确定时：

dBuilder.setEntityResolver(new EntityResolver() {
    @Override
    public InputSource resolveEntity(String publicId, String systemId) {
        // it might be a good idea to insert a trace 
        // logging here that you are ignoring publicId/systemId
        return new InputSource(new StringReader("")); // Returns a valid dummy source
    }
});

我希望角度代码在＆＃34; Ok＆＃34;被按下但不是当＆＃34;取消＆＃34;被按下了。

将confirm扔进$scope.deleteCompany()功能：

function MyCtrl($scope) {
  $scope.deleteCompany = function(id) {
    if (confirm('This will permernently delete the entity\nAre you sure you want to delete this post?')) {
      $scope.name = id;
      // delete the stuff.
    }
  }
}

将其从内联HTML中删除：

<div ng-controller="MyCtrl">
  <button ng-click="deleteCompany('1')" class="btn btn-danger">
    <span class="glyphicon glyphicon-trash"></span>
  </button>
  <button ng-click="deleteCompany('2')" class="btn btn-danger">
    <span class="glyphicon glyphicon-trash"></span>
  </button>
  Hello, {{name}}!
</div>

为什么不将confirm放在deleteCompany方法中？

$scope.deleteCompany = function(id) { 
    if (!confirm("Delete company?"))  
        return;

    console.log(id);
}

使用确认从按钮中的javascript停止角度
