角的1.4.x在SELECT
角最接近孩子在ng-repeat我有一个SELECT控制并根据它的细节DIV。当SELECT更改时，我希望向DIV添加一个类。
BEGIN ng-repeat
<select ng-change="???add a class XYZ to .details ???">...</select>
<div class="details">...</div>
END
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.selection = [];
$scope.isHighlighted = [];
$scope.items = [{
id: 1,
label: 'Label 1',
}, {
id: 2,
label: 'Label 2',
}];
$scope.selectionChanged = function(idx) {
$scope.isHighlighted[idx] = true;
}
});.highlight {
color: red;

正如averything别的角度：修改模型，并采用NG-类添加基于模型的类。如果你发布了真实的代码，它会更容易帮助。 –
