asp.net2.0密码强度验证
1、建立Default.aspx文件，代碼如下：
<%@ Page Language="C#" AutoEventWireup="true"? CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
??? <title>無標題頁</title>
</head>
<script language="javascript" type="text/javascript">?
??? //CharMode函數?
??? //測試某個字符是屬于哪一類.?
??? function CharMode(iN){?
??????? if (iN>=48 && iN <=57) //數字?
??????? return 1;?
??????? if (iN>=65 && iN <=90) //大寫字母?
??????? return 2;?
??????? if (iN>=97 && iN <=122) //小寫?
??????? return 4;?
??????? else?
??????? return 8; //特殊字符?
??? }?
??? //bitTotal函數?
??? //計算出當前密碼當中一共有多少種模式?
??? function bitTotal(num){?
??????? modes=0;?
??????? for (i=0;i<4;i++){?
??????? if (num & 1) modes++;?
??????? num>>>=1;?
??????? }?
??????? return modes;?
??? }?
??? //checkStrong函數?
??? //返回密碼的強度級別?
??? function checkStrong(sPW){?
??????? if (sPW.length<=4)?
??????? return 0; //密碼太短?
??????? Modes=0;?
??????? for (i=0;i<sPW.length;i++){?
??????? //測試每一個字符的類別并統計一共有多少種模式.?
??????? Modes|=CharMode(sPW.charCodeAt(i));?
??????? }?
??????? return bitTotal(Modes);?
??? }?
??? //pwStrength函數?
??? //當用戶放開鍵盤或密碼輸入框失去焦點時,根據不同的級別顯示不同的顏色?
??? function pwStrength(pwd){?
??????? O_color="#e0f0ff";?
??????? L_color="#FF0000";?
??????? M_color="#FF9900";?
??????? H_color="#33CC00";?
??????? if (pwd==null||pwd==''){?
??????????? Lcolor=Mcolor=Hcolor=O_color;?
??????? }?
??????? else
??????? {?
??????????? S_level=checkStrong(pwd);?
??????????? switch(S_level)
??????????? {?
??????????????? case 0:?
??????????????? Lcolor=Mcolor=Hcolor=O_color;?
??????????????? case 1:?
??????????????? Lcolor=L_color;?
??????????????? Mcolor=Hcolor=O_color;?
??????????????? break;?
??????????????? case 2:?
??????????????? Lcolor=Mcolor=M_color;?
??????????????? Hcolor=O_color;?
??????????????? break;?
??????????????? default:?
??????????????? Lcolor=Mcolor=Hcolor=H_color;?
??????????? }?
??????? }?
??????? document.getElementById("strength_L").style.background=Lcolor;?
??????? document.getElementById("strength_M").style.background=Mcolor;?
??????? document.getElementById("strength_H").style.background=Hcolor;?
??????? return;?
??? }?
</script>?
<body>
??? <form id="form1" runat="server">
??? <div>
??????? 輸入密碼:<asp:TextBox ID="TextBox1" runat="server" onKeyUp=pwStrength(this.value) onBlur=pwStrength(this.value) ></asp:TextBox><br />
??????? 密碼強度:
??????? <table border="1" cellpadding="1" borderColorDark="#fdfeff" borderColorLight="#99ccff" cellspacing="1" style="width: 200px; display: inline; background-color:#e0f0ff">
??????????? <tr>
??????????????? <td id="strength_L" style="width: 100px; height: 19px;" align="center">
??????????????????? 弱</td>
??????????????? <td id="strength_M" style="width: 100px; height: 19px;" align="center">
??????????????????? 中</td>
??????????????? <td id="strength_H" style="width: 100px; height: 19px;" align="center">
??????????????????? 強</td>
??????????? </tr>
??????? </table>
??? </div>
??? </form>
</body>
</html>
?
2、Default.aspx.cs代碼如下：
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
public partial class _Default : System.Web.UI.Page
{
??? protected void Page_Load(object sender, EventArgs e)
??? {
??? }
}
?
3：運行效果如下：
