标签:des style code c color width 网上转载的一段代码,留着以后用, js文件: //判断输入密码的类型 //显示颜色 页面:
function CharMode(iN){
if (iN>=48 && iN
return 1;
if (iN>=65 && iN return 2;
if (iN>=97 && iN return 4;
else
return 8;
}
//bitTotal函数
//计算密码模式
function bitTotal(num){
modes=0;
for (i=0;i if
(num & 1) modes++;
num>>>=1;
}
return modes;
}
//返回强度级别
function checkStrong(sPW){
if
(sPW.length return 0; //密码太短
Modes=0;
for
(i=0;i
Modes|=CharMode(sPW.charCodeAt(i));
}
return bitTotal(Modes);
}
function pwStrength(pwd){
O_color="#eeeeee";
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;
}
