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

            canvas: t.PagerCanvas,
            callbackFn: t.flip,
            pageCount: parseInt($("#pageCount").val()),
            pageIndex: parseInt($("#pageIndex").val()),
            point: t

        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

这是js的代码,ajax获取数据,crud的。
