AngularJS - 过滤空的对象 [英] AngularJS - Filter empty objects

问题描述

我有包含数据块一个$ scope.myData对象。我所试图做的是显示的数据，但过滤掉空和空字符串：

I have a $scope.myData object that contain a chunk of data. What i am trying to do is display the data but filter out the nulls and empty strings:

$scope.myData = [
    {
       "ID" : "001",
       "Message" : "test test test test"
    },
    {
       "ID" : "002",
       "Message" : "test test test test"
    },
    {
       "ID" : "003",
       "Message" : "test test test test"
    },
    {
       "ID" : "004",
       "Message" : "test test test test"
    },
    {
       "ID" : "005",
       "Message" : " "
    },
    {
       "ID" : "006",
       "Message" : "test test test test"
    },
    {
       "ID" : "007",
       "Message" : "test test test test"
    },
    {
       "ID" : "007",
       "Message" : null
    }
]

我可以对一个NG重复上面和过滤空的经过：

I can perform an ng-repeat on the above and filter null's via:

<div ng-repeat="data in myData | filter:{Message: '!!'}">
    {{ data.ID }}
    {{ data.Message }}
</div>

但我怎么可以过滤空字符串例如：

But how can i filter the empty strings e.g:

"Message" : " "

感谢

推荐答案

我们可以简单地使用NG-如果在这里：

We can simply use ng-if here:

<div ng-repeat="data in myData " ng-if="data.Message">
 {{ data.ID }}
 {{ data.Message }}
</div>
