angular.js - How to display the ul li from the nested loop of ng-repeat so that the first li has a style by default, and the currently clicked li has a style and the other li have no style?

Question

Question: I use ng-repeat to loop out the data. How do I do this: 1. When opening the page, does the first li displayed by default have a style? 2. Does the currently clicked li have styles, while other li's have no styles?
The following is the html code diagram:

Use ng-class to create a chosenIndex variable in $scope to store the index of the currently selected li. The default is 0. Assume that the selected class is called chosenClass.

{{c.goods_name}}


----------
$scope.chosedIndex = 0;//默认是0使第一个有样式
$scope.twoClick = function(index){
    //保存点击的li位置
    $scope.chosedIndex = index;
}
