jquery 通用表单验证 ...

主要用到了jquery，以及自定义的一个属性wl_check，属性说明如下：

 
1、语法
 [need:true,type:int,maxlen:15,minlen:2]

2、关键字
 need：文本输入框的必填限制
 regtype：文本输入框的正则表达式类别验证
 minlen：文本输入框的最小输入长度
 maxlen：文本输入框的最大输入长度
 minval：数字型文本输入框的最值
 maxval：数字型文本输入框的最值
 notval：下拉框的必选设置
 minselect：单复选框的最少选项数
 maxselect：单复选框的最多选项数
 sequence：默认从100--1000，如果需要打乱页面控件顺序可设置值，<100 或 >1000，按从小到大验证
 group：【group:txtArea-1-1】其中“txtArea”是pre控件值，“-1-1”表示最少填写一个，最多填写一个。
 manage：可以设置与某一控件的关系“= != > < >= <= + -”
 ...

3、使用范围
 input:text
 input:radio 注意id为'_i'
 input:checkbox 注意id为'_i'
 textarea
 select
 
4、描述
a、在有wl_check属性的表单控件值发生变化时会自行调用相应的验证方法，该方法无返回值，只是出错提示并定位。
b、在页面post时需要先对某一域内有wl_check属性的表单控件进行验证，通过返回true；否则弹出提示信息并取消提交。

5、使用示例-见demo
 

        <input type="text" id="name" value='dd' title='姓名' wl_check="need:true,minlen:2,maxlen:10,sequence:1" />
 表示该文本框必填，并且最多10个字，最少2各个字
