电话号码的验证
要求:
(1)电话号码由数字、"("、")"和"-"构成
(2)电话号码为3到8位
(3)如果电话号码中包含有区号,那么区号为三位或四位
(4)区号用"("、")"或"-"和其他部分隔开
(5)移动电话号码为11或12位,如果为12位,那么第一位为0
(6)11位移动电话号码的第一位和第二位为"13"
(7)12位移动电话号码的第二位和第三位为"13"
根据这几条规则,可以与出以下正则表达式:
(^[0-9]{3,4}\-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^\([0-9]{3,4}\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$)

具体的例子:http://202.119.73.208/NetEAn/com/test/jsprint.htm
在每个文本框的onblur事件中调用校验代码,并且每个文本框中onKeyDown事件中写一个enter转tab函数
//回车键换为tab
function enterToTab()
{
if(event.srcElement.type != 'button' && event.srcElement.type != 'textarea'
&& event.keyCode == 13)
{
event.keyCode = 9;
}
}
有时候还需要自由编辑表格---
给大家一个自由编辑表格的小例子,写的有点乱,呵呵:)
