２．验证ＩＰ地址
<script> <BR>function isip(s){ <BR>var check=function(v){try{return (v<=255 && v>=0)}catch(x){return false}}; <BR>var re=s.split(".") <BR>return (re.length==4)?(check(re[0]) && check(re[1]) && check(re[2]) && check(re[3])):false <BR>} <br><br>var s="202.197.78.129"; <BR>alert(isip(s)) <BR></script>

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}$)|(^0{0,1}13[0-9]{9}$)

GetTableData.prototype.GetFieldData = getfielddata;
GetTableData.prototype.Sort_asc = sort_asc;
GetTableData.prototype.Sort_desc = sort_desc;
GetTableData.prototype.GetData = getData;
GetTableData.prototype.Delete = Delete;
GetTableData.prototype.UpdateField = updateField;
GetTableData.prototype.MoveFirst = movefirst;

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:）

自由编辑表格
单击开始编辑按钮,然后点击各单元格编辑	2	3
4	5	6
one	two	three
four	five	six

请单击某个单元格进行编辑!
