this.t;
this.mysort = function() {
//alert("haha");
for(var i = 0; i < this.arr.length; i++) {
var rand = parseint(math.random() * this.arr.length);
this.t = this.arr[rand];
this.arr[rand] = this.arr[i];
this.arr[i] = this.t;

})
app.controller("myctrl", function($scope, sortservice) {
$scope.arr = arr1;
$scope.newarr = sortservice.arr;
$scope.mysort2 = sortservice.mysort;
/*$scope.mysort2 = function(){

})
</script>
</head>
<body ng-app="myapp" ng-controller="myctrl">
{{newarr}}<br><button ng-click="mysort2()">点击随机排序</button> <br>{{arr}}
<!--{{arr}}<button ng-click="mysort2()">点击随机排序</button> {{newarr}}-->
