Question

我有一个表，当我点击<td>时，我需要返回这个td名称和行索引。但是，如果我像ng-click="showIndex(field.name, $index)"那样使它返回td的索引，而不是tr（我知道这是合乎逻辑的:)）。我找到了一些方法来检查父索引，但它是jquery，也许有一种方法来检查角度？ I have some example

您应该在

中使用$parent.$index代替$index

<tr ng-repeat='row in table.row'>
    <td ng-click="showIndex(field.name, $parent.$index)" ng-repeat='field in row.fields'>{{field.name}}</td>
</tr>

var app = angular.module('App', []);

app.controller('Ctrl', function($scope) {
  $scope.table = {
row: [{
  fields: [{
    title: "Your name",
    name: "John",
    id: 'name'
  }, {
    title: "Your second name",
    name: "Doe",
    id: 'secondName'
  }, {
    title: "Your age",
    name: 26,
    id: 'age'
  }, {
    title: "Your sex",
    name: "Male",
    id: 'sex'
  }]
}, {
  fields: [{
    title: "Your name",
    name: "Kevin",
    id: 'name'
  }, {
    title: "Your second name",
    name: "Parker",
    id: 'secondName'
  }, {
    title: "Your age",
    name: 32,
    id: 'age'
  }, {
    title: "Your sex",
    name: "Male",
    id: 'sex'
  }]
}, {
  fields: [{
    title: "Your name",
    name: "Barbara",
    id: 'name'
  }, {
    title: "Your second name",
    name: "Streisand",
    id: 'secondName'
  }, {
    title: "Your age",
    name: 60,
    id: 'age'
  }, {
    title: "Your sex",
    name: "Female",
    id: 'sex'
  }]
}, {
  fields: [{
    title: "Your name",
    name: "Linda",
    id: 'name'
  }, {
    title: "Your second name",
    name: "Lorry",
    id: 'secondName'
  }, {
    title: "Your age",
    name: 20,
    id: 'age'
  }, {
    title: "Your sex",
    name: "Female",
    id: 'sex'
  }]
}]
  };

  $scope.showIndex = function(name, index) {
$scope.showResult = name + ' in the row number ' + index;
  }
});
