Question

我正在使用数据服务器端处理来管理大型数据库。除了分页之外，一切都很完美。它完美地生成了分页按钮，并在我改变页面长度后调用ajax。但它显示的是同一页面中的所有数据。像ajax返回47行，它创建5页，每页包含10行。但它在同一页面中显示47行，并且5页都有47行。这是我的代码

function reportManagement(){
    if (my_details[0].role_id != 1) {
        my_details = JSON.parse(checkSesssion('is_auth'));
        var createdby = my_details[0].id;
    }else{
        var createdby = 1;
    }

    var generateTable = '<div class="card">'+
        '<div class="card-header" data-background-color="purple"><h4 class="title">List of Campaign</h4></div>'+
        '<div class="card-content"></div>'+
        '<div class="row"><div class="col-sm-10 col-sm-offset-1 col-md-10 col-md-offset-1"><div class="card-content table-responsive table-full-width">'+
        '<table id="dataTables_show_list" class="table table-striped table-bordered" cellspacing="0" width="100%"></table></div</div></div></div>';

    $("#editAllAccountTable").empty().html(generateTable);


    var dataInfo = {};
    dataInfo['account_id'] = createdby;
    var table =  $('#dataTables_show_list').DataTable({
        "serverSide": true,
        "processing": true,

        "ajax": {
            url: service_url['get_campaign_details'],

        },
