所以，我有一个数独生成器，当通过 API 访问时，它会生成一个数独板（JSON 数组），然后在表格中使用 AngularJS 和 ng-repeat 我在页面上显示数独板。到目前为止，这就是我所拥有的。我想要实现的是突出显示框中的所有元素以及行和列。现在行和列被突出显示，但是我怎样才能突出显示下图中用黄色标记的元素，因为这些元素属于框：这是我的 HTML 代码：<body ng-app="Sudoku"><!-- SUDOKU BOARD --><div class="sudoku-game" ng-controller="SudokuController"> <table class="sudoku-board" ng-init="getSudoku()"> <tbody> <tr ng-repeat="sudoku in sudokuGrid track by $index" ng-init="row = $index" class="sudoku-row" ng-class="{'highlight':rowSelected === row}"> <td ng-repeat="number in sudoku track by $index" ng-init="col = $index" class="sudoku-col" ng-class="{'highlight':colSelected === col}"> <div class="sudoku-cell" ng-class="{'selected':isSelected === ((row*10) + col)}" ng-click="selectedCell(row, col)" ng-keyup="insertNum($event)" tabindex="1"> <span class="prevalued" ng-if="number !== null" ng-bind="number"></span> <span class="emptycell" ng-if="number === null" ng-bind="emptyCell"></span> </div> </td> </tr> </tbody> </table></div>这是我在 JavaScript 中为 selectedCell(row, col) 函数编写的代码$scope.getCellPosition = function (row, col) { return (row * 10) + col;}$scope.selectedCell = function (row, col) { $scope.isSelected = $scope.getCellPosition(row, col); $scope.rowSelected = row; $scope.colSelected = col; console.log($scope.isSelected);}

您可以在所选单元格的正方形中向单元格添加一个突出显示类：
<div class="sudoku-cell" ng-class="{
'selected':isSelected === ((row*10) + col),
'highlight': isHighlight(row, col),
}" ng-click="selectedCell(row, col)" ng-keyup="insertNum($event)" tabindex="1">
在你的 js 中：
$scope.isHighlight = function (row, col) {
// Add debugging functions
//
console.log({
row,
rowSelected: $scope.rowSelected,
col,
colSelected: $scope.colSelected,
});
// Return the boolean
//
return Math.floor(row / 3) === Math.floor($scope.rowSelected / 3)
&& Math.floor(col / 3) === Math.floor($scope.colSelected / 3)
}
