easyui 的validatebox()提供了自定义验证的方法，为此我把一些常用的数据验证汇总了一下，代码如下：

自定义表单验证，实例：

$.extend($.fn.validatebox.defaults.rules, {            selectValueRequired: {               validator: function(value,param){                return value != '---请选择---';              },              message: '请选择车辆类型'            }         });        $.extend($.fn.validatebox.defaults.rules, {            NUMBERNON: {                validator: function (value, param) {                    return /^[0123456789]\d{0,7}(\.\d{1,2})?$/.test(value);                },                message: '请输入非负数字，最多两位小数'            }            });
