再来看一个选择li列表的例子:
点击li中的任意项,被点击的li高亮显示:
<!DOCTYPE html> <html ng-app> <head> <title>6.3css类和样式</title> <meta charset="utf-8"> <script src="../angular.js"></script> <script src="script.js"></script> <style type="text/css"> li.cur { background:#C0DCC0 } </style> </head> <body> <div ng-controller = "Restaurant"> <ul> <li ng-repeat="restaurant in restaurants" ng-class="{cur:$index==selRow}" ng-click="choose($index)"> <span>{{restaurant.name}}</span><span>{{restaurant.food}}</span><span>{{restaurant.price}}</span> </li> </ul> </div> </body> </html>
function Restaurant ($scope){ $scope.selRow = null; $scope.restaurants = [ {"name":"happy lemon","food":"greenTea","price":"￥15"}, {"name":"coco","food":"milkTea","price":"￥10"}, {"name":"good fruit","food":"fruits","price":"￥20"} ]; $scope.choose = function(i){ $scope.selRow = i } }
ng-class="{cur:$index==selRow}":
在这里,ng-class属性的cur类名,绑定表达式 $index==selRow,
然后给每个li绑定点击事件回调,点击任意li,就把selRow的值变为$index.这样,当前被点击的项就会被添加类名cur,高亮显示.
这里可以看到,angular绑定的事件回调,可以在执行的时候传入参数
原始状态:
点击第二项:
