Question

我正在做Angular JS任务，我需要从文本框中获取输入并形成具有两个输入字段的行。考虑行和列在其中输入值时，形成两个输入字段。具有行和列的表应形成。这是一个小提琴链接

var app = angular.module('app', []);
app.controller('ctrl', function($scope) {
  $scope.table = [];
  $scope.cols = [];
  $scope.rows = [];
  $scope.arr = [];
  $scope.arh = [];
  $scope.trr = [];

  $scope.makeArray = function() {
    $scope.trr.length = 0;
    for (var k = 0; k < parseInt($scope.table); k++) {
      $scope.trr.push(k);
    }
    $scope.arr.length = 0;
    for (var i = 0; i < parseInt($scope.rows); i++) {
      $scope.arr.push(i);
    }
    $scope.arh.length = 0;
    for (var j = 0; j < parseInt($scope.cols); j++) {
      $scope.arh.push(j);

    }
  }

});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.min.js"></script>
<div ng-app="app">
  <div ng-controller="ctrl">
    <input ng-model="table" type="text" ng-change="makeArray()" />
    <table>
      <tr ng-repeat="o in trr">
        <td> <input ng-model="rows[$index]" type="text" ng-change="makeArray()" />
        </td>
        <td> <input ng-model="cols[$index]" type="text" ng-change="makeArray()" /></td>
      </tr>
    </table>
    <div>
      <table>
        <tr ng-repeat="o in arr">
          <td ng-repeat="o in arh">Col</td>
        </tr>
      </table>

    </div>

  </div>
</div>

我可以从文本框中输入内容并形成行。在形成的输入字段中输入值后，将形成一个带有输入值的表。表形式仅适用于第一行输入的值问题是我不能做到超过一行

无法为第二行输入值的表格在上面的小提琴中在文本字段中输入2 2行将形成两个输入字段在第一行输入字段中分别输入3和4 您可以看到一个由3行4列组成的表格当我在第二行中输入值时，我需要做同样的事情第二张表应该形成

   //This piece is wrong right, $scope.rows, $scope.cols are not Strings/Numbers they are arrays and suppose to contain each tabs rows and columns index wise.

   $scope.arr.length = 0;
    for (var i = 0; i < parseInt($scope.rows); i++) {
      $scope.arr.push(i);
    }

    $scope.arh.length = 0;
    for (var j = 0; j < parseInt($scope.cols); j++) {
      $scope.arh.push(j);

    }

var app = angular.module('app', []);
app.controller('ctrl', function($scope) {
   $scope.table = 0;
   $scope.cols = [];
   $scope.rows = [];

   $scope.makeArray = function() {
      if ($scope.table) {
        return new Array(parseInt($scope.table));
      } else {
        return new Array(0);
      }
   }

   $scope.getRowsCount = function ($index) {
      if ($scope.rows[$index]) {
         return new Array(parseInt($scope.rows[$index]));
      } else {
         return new Array(0);
      }
   }

   $scope.getColsCount = function ($index) {
      if ($scope.cols[$index]) {
        return new Array(parseInt($scope.cols[$index]));
      } else {
        return new Array(0);
      }
    }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.6/angular.min.js"></script>
<div ng-app="app">
  <div ng-controller="ctrl">
    <input ng-model="table" type="text" />
    <table>
      <tr ng-repeat="t in makeArray() track by $index">
        <td> <input ng-model="rows[$index]" type="text" />
        </td>
        <td> <input ng-model="cols[$index]" type="text" /></td>
      </tr>
    </table>
    <div>
      <table ng-repeat="t in makeArray() track by $index">
        <tr ng-repeat="r in getRowsCount($index) track by $index">
          <td ng-repeat="c in getColsCount($parent.$index) track by $index">Col</td>
        </tr>
      </table>

    </div>

  </div>
</div>
