js:
$scope.count=1;
$scope.items=[];
$scope.page=1;
$scope.loadMore = function() {
var url = "article/listget?pageNum="+$scope.page+ "&jsonp=JSON_CALLBACK";
$scope.count++;
console.log("第" + $scope.count + "次执行nextPage方法");
console.log("第"+$scope.page+"页");
$http({
method: 'GET',
url: url
}).then(function successCallback(response) {
var items = response.data.data;
console.log(items);
$scope.items=$scope.items.concat(items);
$scope.page++;
}, function errorCallback(response) {
// 请求失败执行代码
}.bind(this));
};
