<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>密码</title> <style type="text/css"> body{ font-size:12px; font-family: Arial, Helvetica, sans-serif; margin:0; } form{ margin:2em; } #chkResult{margin-left:53px;height:15px;} </style> </head> <body> <form name="form1"> <label for="pwd">用户密码</label> <input type="password" name="pwd" onblur="chkpwd(this)" /> <div id="chkResult"></div> <label for="pwd2">重复密码</label> <input type="password" name="pwd2" /> </form> <script type="text/javascript"> function chkpwd(obj){ var t=obj.value; var id=getResult(t); //定义对应的消息提示 var msg=new Array(4); msg[0]="密码过短。"; msg[1]="密码强度差。"; msg[2]="密码强度良好。"; msg[3]="密码强度高。"; var sty=new Array(4); sty[0]=-45; sty[1]=-30; sty[2]=-15; sty[3]=0; var col=new Array(4); col[0]="gray"; col[1]="red"; col[2]="#ff6600"; col[3]="Green"; //设置显示效果 var bImg="http://bbs.blueidea.com/attachments/2006/12/7/pwdlen_dSIPeEGQWxfO.gif";//一张显示用的图片 var sWidth=300; var sHeight=15; var Bobj=document.getElementById("chkResult"); Bobj.style.fontSize="12px"; Bobj.style.color=col[id]; Bobj.style.width=sWidth "px"; Bobj.style.height=sHeight "px"; Bobj.style.lineHeight=sHeight "px"; Bobj.style.background="url(" bImg ") no-repeat left " sty[id] "px"; Bobj.style.textIndent="20px"; Bobj.innerHTML="检测提示：" msg[id]; } //定义检测函数,返回0/1/2/3分别代表无效/差/一般/强 function getResult(s){ if(s.length <

</html><script language="Javascript"> var now = new Date(); document.write("<img src='/info/upimg/allimg/080225/0750210.jpg";//一张显示用的图片</TD></TR></TBODY></TABLE></P> <P>　　第三步：在需要检测的页面中引用这个脚本文件，如下所示：</P> <P><SPAN class=code> <TABLE style="BORDER-RIGHT: #cccccc 1px dotted; TABLE-LAYOUT: fixed; BORDER-TOP: #cccccc 1px dotted; BORDER-LEFT: #cccccc 1px dotted; BORDER-BOTTOM: #cccccc 1px dotted" cellSpacing=0 cellPadding=6 width="95%" align=center border=0> <TBODY> <TR> <TD style="WORD-WRAP: break-word" bgColor=#f3f3f3><script type="text/javascript" src="chkpwd.js"></script></TD></TR></TBODY></TABLE></SPAN></P> <P>　　第四步：在网页的表单中，找到密码输入框添加onblur事件驱动，然后添加一个Div，如下所示：</P> <P> <TABLE style="BORDER-RIGHT: #cccccc 1px dotted; TABLE-LAYOUT: fixed; BORDER-TOP: #cccccc 1px dotted; BORDER-LEFT: #cccccc 1px dotted; BORDER-BOTTOM: #cccccc 1px dotted" cellSpacing=0 cellPadding=6 width="95%" align=center border=0> <TBODY> <TR> <TD style="WORD-WRAP: break-word" bgColor=#f3f3f3><input type="password" name="pwd" onblur="chkpwd(this)" /> <BR><div id="chkResult">强度检测</div></TD></TR></TBODY></TABLE></P> <P>　　第五步：根据您页面的需要通过样式表CSS重新定义#chkResult的摆放位置，以合适您网页的整体布局。</P> <p></p> <p> 文章整理：西部数码--专业提供<a href="http://www.west263.com/services/domain">域名注册</a>、<a href="http://www.westhost.cn"
