}

AjaxForm 的实现依靠namespace.js的库，，，主要的功能包含了序列form提交的数据，验证，发送。

AjaxForm 采用的了混合继承的方式来完成继承功能AutoAjax 运行过程为主要实例化ajaxform对象，再找到form对象进init的初始化其中init初始化是根据ns-data属性值进行初始化，将ns-data转化为json，然后赋值给ajaxform变量，然后依次绑定相应的事件行为例如：

ns-data = "successFn:‘ajaxFormSuccess/*函数名存储在Ns.UI.AjaxForm.SuccessFns空间内*/‘

,submitBtn:‘.login_btn/*提交按钮选择表达式*/‘

,validateFn:‘ajaxFormValidate/*自定义验证函数名存储在Ns.UI.AjaxForm.ValidateFns空间内*/‘

,validateFailt:‘validate/*自动化验证（ajaxForm内验证失败的时的函数名存储在Ns.UI.AjaxForm.ValidateFns空间内）*/‘

,isMultiErr:false"而自动化验证表达式则在标签内添加

验证规则则保存在标签内，以ns-validate属性保存

ns-validate属性

ns_validate = "rules:[]/*正则规则*/

,target:‘.error_text/*错误信息显示在哪*/‘

,errorcls:‘error_ipt/*验证未通过，标签添加的类*/‘

,notnul:true/*是否允许为null*/

,nultext:‘登陆用户名不能为空‘/*未null时提醒错误信息*/" }
