这个通用操作类相当于JSP页面从struts2里action里找到相应的方法吗

//增删改查通用操作类
PageHelper = {
    Entity: function () { },
    getInstance: function () {
        return new this.Entity();
    }
};

PageHelper.Entity.prototype = {
    ContentContainer: null,
    CheckBoxAll: null,
    FlipParams: {
        "conditions": null,
        "pageIndex": null,
        "pageSize": null,
        "multipleIds": null
    },
    Model: null,
    PagerCanvas: "#Pager",
    Url: {
        add: null,
        load: null,
        modify: null,
        remove: null,
        template: null
    },
    //method
    add: function (callback) {
        $.ajaxPostJson(this.Url.add, this.Model, callback);
    },
    ajax: function (url, param, callback) {
        $.ajaxPostJson(url, param, callback);
    },
    //翻页
    flip: function (i, initPagerFlag) {
        var _t = this;
        if (typeof this.FlipParams == "undefined" && this.point)
            _t = this.point;
        //Ajax请求参数
        _t.FlipParams.conditions = _t.Model;
        _t.FlipParams.pageIndex = i || parseInt($("#pageIndex").val());
        _t.FlipParams.pageSize = parseInt($("#pageSize").val() || "10");
        _t.FlipParams.multipleIds = $("#multipleIds").val();

        //发送AJAX请求分页数据并填充
        $.ajaxPostJson(_t.Url.load, _t.FlipParams, function (jsn) {

            if (jsn.status) {
                $(_t.ContentContainer).html("");
                if (jsn.resultHtml) {
                    $(_t.ContentContainer).html(jsn.resultHtml);
                }
                else if (jsn.list) {
                    $(_t.ContentContainer).empty().setTemplateURL(_t.Url.template);
                    $(_t.ContentContainer).processTemplate(jsn.list);
                    //OC审计报告汇总 Modify by yhl 2014/3/25 start
                    var checkedLength = $(_t.ContentContainer+" input[type=checkbox][checked]").length;
                    if (checkedLength >0 && checkedLength == _t.FlipParams.pageSize) {
                        $(_t.CheckBoxAll).attr("checked",true);
                    } else {
                        $(_t.CheckBoxAll).removeAttr("checked");
                    }
                    //OC审计报告汇总 Modify by yhl 2014/3/25 end
                    setTimeout(function () { showButtons() }, 0);
                    //Modify By zhexin.zou 2013/8/7 start
                    setTimeout(function () { bindSelectFunc('staffList'); }, 500);
                    //Modify By zhexin.zou 2013/8/7 end
                }
                if (initPagerFlag) {
                    $(_t.PagerCanvas).html("");
                    $("#pageIndex").val("1");
                    $("#pageCount").val(jsn.pageCount);
                    _t.pagerInit();
                };
            } else {
                if (jsn.message) alert(jsn.message);
            }
        });
    },
    //修改记录
    modify: function () {
        $.ajaxPostJson(this.Url.modify, this.Model, void (null));
    },
    query: function () {
        this.flip(1, true);
    },
    //删除记录
    remove: function (callBack) {
        $.ajaxPostJson(this.Url.remove, this.Model, function (jsn) {
            if (jsn) {
                if (jsn.status) {
                    if (callBack)
                        callBack(jsn);
                    else {
                        alert(jsn.message);
                    }
                }
                else {
                    alert(jsn.message);
                }
            }
        });

    },
    //初始化
    pagerInit: function (t) {
        t = t || this;
        var pagerParam = {
            canvas: t.PagerCanvas,
            callbackFn: t.flip,
            pageCount: parseInt($("#pageCount").val()),
            pageIndex: parseInt($("#pageIndex").val()),
            point: t
        };
        var pg = Pager.getInstance();
        pg.init(pagerParam);
    }
};
//填充模型
var fillModel = function (model, index) {
    var val;
    for (var m in model) {
        //val = $.trim($("#" + m + index.toString()).val()) || null;
        var el = $("#" + m + index.toString());
        if (el.attr("type") == "checkbox") {
            val = el.is(":checked");
        }
        else
            val = $.trim(el.val()) || null;
        model[m] = val;
    };
    model.id = $("#editID").val() || 0;
    return model;
};

$("#inptAddNew").on("click", function () {
    $(".readOnlyOnEdit").removeAttr("readonly");
});

下面的代码调用上面的通用操作类
$(function () {
var url = {

load: contextPath + "/ouQuery/searchReport",
remove: contextPath+"/ouQuery/delet",
template: contextPath + "/resources/templates/pricelzx/OuQuery.tpl",
add: contextPath + "/ouQuery/edit"
};
var ph = PageHelper.getInstance();
var lb = new lightBox();
ph.Url = url;
ph.ContentContainer = "#tbList tbody";
ph.pagerInit();
// query
$("#inptQuery").on("click", function () {
//查询时执行验证
if (!new Validate().execute("tbQuery")) {
return false;
}

    var ouQueryModel = Model.OuQuery;
    ph.Model = fillModel(ouQueryModel,1);
    ph.query();

});

    第二个代码
     //delete删除
$("table input.del").live("click", function () {
    if (confirm(regional.operate.deleteConfirm)) {
        var ouQueryModel = Model.OuQuery;
        ouQueryModel.id = $(this).parent().siblings().first().attr("data");
        ph.Model = ouQueryModel;
        ph.remove(null);

        //reset params
        ph.Model = fillModel(ouQueryModel, 1);
        ph.query();
        lb.hide();
    }
});

      ph.remove(null);为什么括号里是null

解决方案

这是js的代码，ajax获取数据，crud的。
