angularJS——利用theParam实现缓存功能

需求：列表页分页，跳转详情页时，保存当前页数和搜索关键词。从详情页返回时，回到之前页数并搜索同一关键词。

js:

mainApp.factory('theParam', function() {
    return {
        currentPage : 1,pageSize : 12,param:''
    };
});

mainApp.controller('listController', function($scope, $http,theParam) {
    
    $scope.currentPage = theParam.currentPage;
    $scope.pageSize = theParam.pageSize;
    $scope.param = theParam.param; //搜索词

    $scope.dataList;
    var dataObj = new Object(),
        reqUrl = "****";
    var initObj = function(){
        dataObj.pageNumber = $scope.currentPage;
        dataObj.pageSize = $scope.pageSize;
        dataObj.param = $scope.param;
    }

　　//*****省略其他******
    
    //以跳转指定页数为例
    $scope.goXpage = function(x) {
        initObj();
　　　　　dataObj.pageNumber = x;
        theParam.param = $scope.param;  //保存关键词   
        $http({
            method : 'get',
            params : {
                param : $.toJSON(dataObj)
            },
            data : {},
            url : reqUrl
        })
        .success(function(response, status, headers, config) {var rstate = response.result;
            if (rstate == "0") {
                var _data = response.message;
                $scope.dataList = _data.glist;
                $scope.currentPage = _data.pageNumber;                
                theParam.currentPage = _data.pageNumber; //保存页数        
　　　　　　　}
     　　　　else{
                Showbo.Msg.alert('fail: '+response.error);
            }
        })
        .error(function(response, status, headers, config) {
            Showbo.Msg.alert('error: '+response.error);
        });
    };    
}
