为什么嵌套NG-电网高度不起作用？ [英] Why nested ng-grid height does not work?

问题描述

我有一个嵌套的NG网格。

I have a nested ng grid.

var faculty = angular.module('faculty', ['ngGrid']);

faculty.controller('facultycontroller', function facultycontroller($scope, $http, $window)
{

$scope.facdata = [{

    examname: 'test'       
  },{

    examname: 'test2'
  }];

  $scope.gridOptions = {

    data: 'facdata',

    plugins: [new ngGridFlexibleHeightPlugin()],

    columnDefs: [
      {field: 'examname',displayName: 'Exam Name'},
      {field: '', displayName: 'Subjects' , cellTemplate: '<div  ng-grid="gridOptions1"  ></div>'
    }]
  };
$scope.fac1data = [{
    abc: 'value',
    def: 'value2'
  }, {

    abc: 'value3',
    def: 'value4'
  }, {
    abc: 'value1',
    def: 'value4'
  }, {
    abc: 'value2',
    def: 'value4'
  }, {
    abc: 'value34',
    def: 'value4'
  }, {

    abc: 'value34',
    def: 'value4'
  }, {
    abc: 'value23',
    def: 'value14'
  }, {
    abc: 'value433',
    def: 'value5554'
  }, {

    abc: 'value3555',
    def: 'value4878'
  }
  ];
$scope.gridOptions1 = {

   plugins: [new ngGridFlexibleHeightPlugin()],

    data: 'fac1data',

    columnDefs: [

      {  field: 'abc',displayName: 'abc'},

      { field: 'def',displayName: 'def'}]
  }
});

查看 Plunker
我需要显示所有的嵌套数据网格一目了然。我需要一览（不垂直滚动），显示孩子NG-网格数据。但是，网格嵌套的高度不起作用。我的愿望电网是像下面....

See the Plunker I need to show all of the nested data grid at a glance. I need to show child ng-grid data at a glance(without Vertical scroll). But nested grid height does not work . My desire grid is like below....

推荐答案

纳克网不是为嵌套网格： 或细胞甚至是动态的高度细胞的

如果你看看NG-网格的模板 UI-grid.html 您看到的大小是固定的像素：

If you look ng-grid's template ui-grid.html you see that the size is fixed in pixels:

  height: {{ grid.options.rowHeight }}px;

看的 github上

本 CSS 的类被嵌入在模板中，不留下任何空间过写为自动。由于电网与内置的div ，而不是表，行和列的表格的关系是困难的，如果每个细胞DIV 可以自由地决定它自己的行为。因此，嵌套的网格是相当的挑战。

see github

This CSS class is embedded in the template, leaving no room to over-write to "auto". Since grids are built with Div's rather than Tables, tabular relationships between rows and columns is difficult if every cell-div is free to decide it's own behavior. So nested grids are quite the challenge.

您可以得到你想要的是一个类似于嵌套网格黑客的影响

折叠电网

Collapsed Grid

注意：尖的已被添加到显示父行的扩展。我have'nt添加逻辑来隐藏有没有孩子父行插入符号。

note: The caret's have been added to show that parent rows are expandable. I have'nt added logic to hide carets for parent rows that have no children.

扩展电网

Expanded Grid

改变你的JSON 以包括测试，名称，ANDD分数列。使用两种测试名称或学生姓名/得分列。使用父ID为孩子，给身份证的家长：

Alter your JSon to include a column for Test, Name, andd Score. Use columns for either Test names or Student Names/Scores. use parent id for children and give id's to parents:

$scope.facdata  = [{test: "Basic Physics Test", parentId:0,id:1,expanded:true},
                 {name: "NAME", Score: "SCORE",parentId:1,expanded:false},
                 {name: "John", Score: 77,parentId:1,expanded:false},
                 {name: "Jacob", Score: 66,parentId:1,expanded:false},
                 {name: "Jenny", Score: 94,parentId:1,expanded:false},
                 {test: "Advanced Physics Test",id:2, parentId:0,expanded:true},
                 {name: "NAME", Score: "SCORE",parentId:2,expanded:false},
                 {name: "Freddy", Score: 94,parentId:2,expanded:false},
                 {name: "Samantha", Score: 38,parentId:2,expanded:false},
                 {name: "Judy", Score: 100,parentId:2,expanded:false}
                 ];

网格选项设置 rowTemplate 使用 NG-节目对孩子的指令对扩展字段

In Grid Options set rowTemplate to use ng-show directive on the children against the expanded field

$scope.gridOptions = { 
    data: 'facdata',
    columnDefs: [{field: 'id',displayName:'',width:20,
    cellTemplate:'<div ng-show="row.getProperty(\'id\')" ng-click="toggleExpansion(row.getProperty(col.field))"><i class="fa fa-caret-right"></i></div>'},
                {field: 'test', displayName: ''},
                {field: 'name', displayName:''},
                 {field:'Score', displayName:'', 
                 cellTemplate: '<div class="ngCellText">{{row.getProperty(col.field)}}</div>'}],
    rowTemplate:'<div style="width: 600px" ng-show="row.getProperty(\'expanded\')"><div ng-repeat="col in renderedColumns" class="ngCell ">' +
                       '<div ng-cell></div> </div></div>'

添加ToggleSubReport功能来管理显示嵌入式数据

Add a ToggleSubReport function to manage showing the embedded data

$scope.ToggleSubReport  = function(id) {
  for (var i=0;i<$scope.facdata.length;++i){
    if ($scope.facdata [i].parentId ===id){
      $scope.facdata [i].expanded = !$scope.facdata [i].expanded;
    }
  }
}

1）嵌套网格是不可能的：
这是你的主要问题和目标。这就是你把一个赏金上。但你可以看到从的 github上 sourcefor网格行高（以像素为单位定义），并从 NG-电网响应的贡献者，这不一个选项，但他们甚至设想。 NG-Grid的的单元格高度并不是真正意义上的动态，因为 NG-格的的设计是围绕匹配大小的div 行，而不是一个表（可多了，自然重新大小的行和列细胞）。

1) Nested Grids are not possible: This was your main question and aim. This is what you put a bounty on. But as you can see from github sourcefor grid-row height (defined in pixels) and responses from ng-grid contributors, this is not an option yet they even envision. NG-Grid's cell height is not truly dynamic because ng-grid is designed around matching sized divs rows rather than a table (which can more naturally re-size rows and row-cells).

2）的那种我发现你真的能适应复杂的主 - 子关系的分格：：您可以序列化之前合并阵列（或解析 JSON 字符串数组，然后将它们合并）。你必须重新定义我用于主 - 从匠气 ID / PARENTID 我用领域的 PK / FK 的2列出。

2) A Sub-Grid of the kind I showed you really can accomodate sophisticated master-child relationships: You can merge arrays before serializing them (or parse JSON strings to arrays, then merge them). You must redefine the fields I used for master-detail from the unimaginative id/parentid I used to the PK/FK of the 2 lists.
