后端验证就不说了

 

js验证的——以前下载过普元的一个js验证的代码。很多,我自己也写了一个simple的,但还算好用。为了使form好看点,用了blueprint。JQuery可选。

 

下面贴几段代码

 

    php template file, html head

 如果你把那么的判断改为switch case 呢.

一大堆的if else 看着头都大了

网上找个通用的验证好了
或者用jquery官方的form验证

js是一个***,自己随便用个就行

主要我是说这么做可以不用写额外代码

des="****" name="****" id="****" value="" restrict="required int"

汗……js验证用什么都可以……我的意思主要在下面三点

error_tag_id
restrict attribute
warn_type

当然也可以说在onload时候来个init_form_valid

……汗,你们都强调js验证具体value了,这个在网上都找的到

这种,具体放到js里撒,写到input里……多不好看……

lz显然没有仔细看别人写的代码,也没看别人写的使用方法。

给lz一个参考的原因是我实在看不下lz的代码,随便网上搜了一个,觉得值得lz学习,就发给lz看了,是好意。

上javaeye的目的是学习。如果有人能给我写的代码提出更好的实现方式,我一定非常感谢他。如果我写的代码没有人可以给我提出更好的建议,那我就没有必要来这里了。

lz的代码只要轻轻一改(把你的几个if else改成switch(或者再好些,用一个数组来循环),把那么多个check_...函数合为一个)就能让你的代码量减少2/3,可读性,科维护性提高好几倍。把易变的东西抽象出来,同样的代码不要拷贝多次。
