customFilters.js
angular.module("customFilters",[])
.filter("unique", function () {
return function (data,propertyName) {
if(angular.isArray(data)&&angular.isString(propertyName)){
var results=[];
var keys={};
for (var i=0;i<data.length;i++){
var val=data[i][propertyName];
if(angular.isUndefined(keys[val])){
keys[val]=true;
results.push(val)

}
return results;

return data;

}
})
应该是过滤器的问题，我刚刚开始学，找不出哪里错了啊0 0大神在哪里
你的sportsStore有依赖注入customFilters吗？
或者你先把customFilters改成sportsStore尝试一下
你是先创建sportsStore module的，后面再引入controllers/sportsStore.js，
在sportsStore.js文件里面将
angular.module("customFilters",[])修改为angular.module("customFilters")，因为sportsStore module已经创建好了，无需再重新创建
