3.密码强度的实现
如果开发中遇到这样的功能，完成可以照搬ecshop4这个功能
它的是原理：根据Unicode 编码来判断密码的强弱。
代码语言：txt复制 <tr>
<td align="right">{$lang.label_password}</td>
<td>
<input name="password" type="password" id="password1" onblur="check_password(this.value);"
onkeyup="checkIntensity(this.value)" class="inputBg" style="width:179px;" />
<span style="color:#FF0000" id="password_notice"> *</span>
</td>
</tr>
<tr>
<td align="right">{$lang.label_password_intensity}</td>
<td>
<table width="145" border="0" cellspacing="0" cellpadding="1">
<tr align="center">
<td width="33%" id="pwd_lower">{$lang.pwd_lower}</td>
<td width="33%" id="pwd_middle">{$lang.pwd_middle}</td>
<td width="33%" id="pwd_high">{$lang.pwd_high}</td>
</tr>
</table>
</td>
</tr>checkIntensity(this.value)这个函数就是判断密码强度，它写在user.js里面
代码语言：txt复制/* *
* 检测密码强度
* @param string pwd 密码
*/
function checkIntensity(pwd)
{
var Mcolor = "#FFF",Lcolor = "#FFF",Hcolor = "#FFF";//定义三种颜色，强、中、弱
var m=0;
var Modes = 0;
for (i=0; i<pwd.length; i )
{
var charType = 0;
var t = pwd.charCodeAt(i); //得出Unicode 编码编码，值越大，密码就越复杂
if (t>=48 && t <=57)
{
charType = 1;
}
else if (t>=65 && t <=90)
{
charType = 2;
}
else if (t>=97 && t <=122)
charType = 4;
else
charType = 4;
Modes |= charType;
}
for (i=0;i<4;i )
{
if (Modes & 1) m ;
Modes>>>=1;
}
if (pwd.length<=4)
{
m = 1;
}
switch(m)
{
case 1 :
Lcolor = "2px solid red";
Mcolor = Hcolor = "2px solid #DADADA";
break;
case 2 :
Mcolor = "2px solid #f90";
Lcolor = Hcolor = "2px solid #DADADA";
break;
case 3 :
Hcolor = "2px solid #3c0";
Lcolor = Mcolor = "2px solid #DADADA";
break;
case 4 :
Hcolor = "2px solid #3c0";
Lcolor = Mcolor = "2px solid #DADADA";
break;
default :
Hcolor = Mcolor = Lcolor = "";
break;
}
if (document.getElementById("pwd_lower"))
{
document.getElementById("pwd_lower").style.borderBottom = Lcolor;
document.getElementById("pwd_middle").style.borderBottom = Mcolor;
document.getElementById("pwd_high").style.borderBottom = Hcolor;
}
}
