jquery自定义类和派生类写法一例

//定义抽象类 基类 表单元素
; (function () {
//
$.FormElement = function () {
//var e = $('#' + e_name);
//默认属性值
var m_oid = '';
var m_Name = '';
var m_width = 800;

//属性的获取与设置方法
this.oid = function () {

//添加方法

//定义js表单对象 FormObject:FormElement 从FormElement基类派生
;(function(){
$.FormObject = function () {
var base = new $.FormElement();
//定义属性
//编辑表名
var m_edit_table_oid = '';
this.edit_table_oid = function () {

}
this.edit_table_oid_set = function (value) {

//比例显示
var m_is_scaledisplay = false;
this.is_scaledisplay = function () {

this.is_scaledisplay_set = function (value) {
m_is_scaledisplay = value;
}
//返回函数本身对象与base对象合并体
return $.extend(true,base, this);
};
})(jQuery);

//测试类代码
var fo = new $.FormObject();
fo.oid_set('oid');
alert(fo.oid());
//
alert(fo.height());
fo.height_set(1000);
alert(fo.height());
//
fo.edit_table_oid_set('ddsssggg');
alert(fo.edit_table_oid());
fo.Msg('good');
