    $scope.currentPage = theParam.currentPage;
    $scope.pageSize = theParam.pageSize;
    scope.param $ = theParam.param; // search terms

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

　　// ***** ****** omitted other
    
    // the specified page to jump Case 
    $ scope.goXpage = function (X) {
