如果使用 angular js 有值列表，如何在一列中生成嵌套表? [英] How do I generate nested table in one column if it has list of values using angular js?

问题描述

index.js

var app = angular.module('plunker', []);app.controller('MainCtrl', function($scope) {$scope.name = '世界';$scope.data =[{"Id":1,"Title":"en-US","Description":"UnitedStates","MyValues":[{"Id":100,"Value":"Save"}]},{"Id":1,"Title":"en-UK","Description":"UK","MyValues":[{"Id":102,"Value":"Delete"}]}]$scope.cols = Object.keys($scope.data[0]);$scope.notSorted = function(obj){如果(！对象){返回 [];}返回 Object.keys(obj);}});

index.html

<头><tr><th ng-repeat="key in notSorted(cols)" ng-init="value=cols[key]">{{value}}</th></tr></thead><tr ng-repeat="数据中的行"><td ng-if="!$last" ng-repeat="dat in notSorted(row)" ng-init="value=row[dat]">{{value}}</td></tr></tbody>

它给了我完美的表格，但问题是在一列 MyValues 中.我有数据列表，想要创建包含所有列表值的嵌套表.

<块引用>

我怎样才能做到这一点?想要检查是否有任何列有 List 如果是然后生成嵌套表.检查这个 plunker http://plnkr.co/edit/Ixvp8B0dRwOBDHflmu2j?p=preview

解决方案

你这样写你的标记:

<头><tr><th ng-repeat="(k,v) in data[0]">{{k}}</th></tr></thead><tr ng-repeat="数据中的项目"><td ng-repeat="(prop, value) in item" ng-init="isArr = isArray(value)"><table ng-if="isArr"><头><tr><th ng-repeat="(sh, sv) in value[0]">{{sh}}</th></tr></thead><tr ng-repeat="sub in value"><td ng-repeat="(sk, sv) in sub">{{sv}}</td></tr></tbody><span ng-if="!isArr">{{value}}</span></td></tr></tbody>

index.js

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';

  $scope.data =[{"Id":1,"Title":"en-US","Description":"UnitedStates","MyValues":[{"Id":100,"Value":"Save"}]},
{"Id":1,"Title":"en-UK","Description":"UK","MyValues":[{"Id":102,"Value":"Delete"}]}]
  $scope.cols = Object.keys($scope.data[0]);

  $scope.notSorted = function(obj){
    if (!obj) {
        return [];
    }
    return Object.keys(obj);
}
});

index.html

<table border=1>
      <thead>
        <tr>
          <th ng-repeat="key in notSorted(cols)" ng-init="value=cols[key]">{{value}}</th>
        </tr>
      </thead>
      <tbody>
        <tr ng-repeat="row in data">
          <td ng-if="!$last" ng-repeat="dat in notSorted(row)" ng-init="value=row[dat]">{{value}}</td>
        </tr>
      </tbody>
    </table>

It gives me perfect table but problem is in one column MyValues. I have list of data and want to create nested table with all List value.

How can I achieve this? Want to check if any column has List if yes then generate nested table. check this plunker http://plnkr.co/edit/Ixvp8B0dRwOBDHflmu2j?p=preview

解决方案

You write your markup this way:

<table>
  <thead>
    <tr>
      <th ng-repeat="(k,v) in data[0]">{{k}}</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="item in data">
      <td ng-repeat="(prop, value) in item" ng-init="isArr = isArray(value)">
        <table ng-if="isArr">
          <thead>
            <tr>
              <th ng-repeat="(sh, sv) in value[0]">{{sh}}</th>
            </tr> 
          </thead>
          <tbody>
            <tr ng-repeat="sub in value">
              <td ng-repeat="(sk, sv) in sub">{{sv}}</td>
            </tr>
          </tbody>
        </table>
        <span ng-if="!isArr">{{value}}</span>
      </td>
    </tr>
  </tbody>
</table>
