angular ng-repeat元素swiper无法滑动问题解决

observer:true,//修改swiper自己或子元素时，自动初始化swiper
observeParents:true,//修改swiper的父元素时，自动初始化swiper

<div ng-controller="myCtrl" class="swiper-container">
    <ul class="swiper-wrapper">
        <li ng-repeat="item in arr"  class="swiper-slide">{{item}}</li>
    </ul>
</div>

var app = angular.module("myApp", []);
app.controller("myCtrl", ["$scope", function ($scope) {
    $scope.arr = [1, 2, 3, 4, 5];;
    var mySwiper = new Swiper(‘.swiper-container‘,{
        grabCursor:true,
        spaceBetween:10,
        freeMode:true,
        observer:true,
        observeParents:true
    })
}])
