Question

我想使用标签来隐藏和显示ng-repeat中的项目。是否可以像这样更改范围的值？

 <a ng-click="packageType = '1'">Package 1</a><a ng-click="packageType ='2'">Package 2</a><a ng-click="packageType = '3'">Package 3</a>
<div ng-repeat="item in packages" ng-show="packageType >=item.packageID">
{{item.name}}</div>

和范围：

$scope.packages = [...{ "name": "some name",
                    "packageID": 1}...]

哪里packageID可以是1,2或3？

我会编写一个函数来封装你想要点击的内容。这样可以更容易理解。

Answer 3

所以我假设包是一个数组，你发布的不是你的完整代码。您需要更改ng-show以说明

ng-show="packageType == item.packageID"

如果packageID与包类型相同，则只显示div。您的ng-click应该可以正常工作。您需要在控制器中的某个位置为packageType设置默认值，但最初会显示

Answer 4

您的代码存在一些问题：

您首先点击是没有结束报价。

# Let's first fetch the last index of seq length
# last_index would have a scalar value
last_index = tf.shape(output)[1] 
# Then let's reshape the output to [sequence_length,batch_size,num_units]
# for convenience
output_rs = tf.transpose(output,[1,0,2])
# Last state of all batches
last_state = tf.nn.embedding_lookup(output_rs,last_index)

稍后将packageType设置为字符串：

<a ng-click="packageType = '1'>Package 1</a>

您在ng-show

中不需要{{}}

packageType ='2'
$scope.packages = { "name": "some name",
                    "packageID": 1}

我认为你认为包是一个数组而不是一个对象：

ng-show="packageType >={{item.packageID}}"

如何操作的示例如下。我将其设置为显示在第二和第三个链接上：

＆＃13;

$scope.packages = { "name": "some name",
                    "packageID": 1}

＆＃13;

(function() {
  'use strict';

  angular
    .module('exampleApp', [])
    .controller('ExampleController', ExampleController);

  function ExampleController($scope) {
    var vm = this;
    $scope.packageType = 1;
    $scope.packages = [{
      "name": "some name1",
      "packageID": 2
    }, {
      "name": "some name2",
      "packageID": 2
    }, {
      "name": "some name3",
      "packageID": 2
    }, {
      "name": "some name4",
      "packageID": 3
    }, {
      "name": "some name5",
      "packageID": 3
    }, {
      "name": "some nam6",
      "packageID": 3
    }];
  }
  ExampleController.$inject = ['$scope'];
})();

＆＃13;

在ng-click上更改范围值
