特效介绍
智能判断密码框密码强度的jQuery特效,输入前,会提示“6-16位,由字母(区分大小写)、数字、符号组成”并呈现灰显,输入框获取焦点会变成红色。输入框下面有判断强度的三个色条,也呈现灰显。当输入1个字符时,色条的第一个会呈现红色,表示非常弱,输入到6个字符时,后面提示文字消失。随着输入字符的复杂化,第二个色条会显示,表示密码强度中等,到输入非常复杂时,第三个色条会显示,表示非常强。当输入超过16个字符时,你会发现,再输入也输不进去了。使用方法
1、在head区域引入jQuery库和css文件:<script src="http://www.5imoban.net/download/jquery/jquery-1.8.3.min.js" type="text/javascript"></script> <link href="Css/style.css" rel="stylesheet" type="text/css" />2、在body区域引入下面的代码:
<form name="form1" method="post" action="register.aspx" id="form1"> <div id="pnBefore" class="t_zc_tc_a_tizhuce_a"> <div class="t_zc_tc_a_tizhuce_bg"> <div class="ywz_zhuce_bao" style="height: 580px; padding: 40px 0 0 0 !important; border-right: none !important; margin-bottom: 0px;"> <div class="t_ywz_fuzai_yi"></div> <div class="t_ywz_fuzai_yi"></div> <div class="ywz_zhucexiaobo"> <div class="ywz_zhuce_youjian"> 设置密码:</div> <div class="ywz_zhuce_xiaoxiaobao"> <div class="ywz_zhuce_kuangzi"> <input name="tbPassword" type="password" id="tbPassword" class="ywz_zhuce_kuangwenzi1" /> </div> <div class="ywz_zhuce_huixian" id='pwdLevel_1'> </div> <div class="ywz_zhuce_huixian" id='pwdLevel_2'> </div> <div class="ywz_zhuce_huixian" id='pwdLevel_3'> </div> <div class="ywz_zhuce_hongxianwenzi"> 弱</div> <div class="ywz_zhuce_hongxianwenzi"> 中</div> <div class="ywz_zhuce_hongxianwenzi"> 强</div> </div> <div class="ywz_zhuce_yongyu1"> <span id="pwd_tip" style="color: #898989"><font style="color: #F00">*</font> 6-16位,由字母(区分大小写)、数字、符号组成</span> <span id="pwd_err" style="color: #f00; display:none;">6-16位,由字母(区分大小写)、数字、符号组成</span> </div> </div> </div> </div> </div> </div> <script type="text/javascript"> $('#tbPassword').focus(function () { $('#pwdLevel_1').attr('class', 'ywz_zhuce_hongxian'); $('#tbPassword').keyup(); }); $('#tbPassword').keyup(function () { var __th = $(this); if (!__th.val()) { $('#pwd_tip').hide(); $('#pwd_err').show(); Primary(); return; } if (__th.val().length < 6) { $('#pwd_tip').hide(); $('#pwd_err').show(); Weak(); return; } var _r = checkPassword(__th); if (_r < 1) { $('#pwd_tip').hide(); $('#pwd_err').show(); Primary(); return; } if (_r > 0 && _r < 2) { Weak(); } else if (_r >= 2 && _r < 4) { Medium(); } else if (_r >= 4) { Tough(); } $('#pwd_tip').hide(); $('#pwd_err').hide(); }); function Primary() { $('#pwdLevel_1').attr('class', 'ywz_zhuce_huixian'); $('#pwdLevel_2').attr('class', 'ywz_zhuce_huixian'); $('#pwdLevel_3').attr('class', 'ywz_zhuce_huixian'); } function Weak() { $('#pwdLevel_1').attr('class', 'ywz_zhuce_hongxian'); $('#pwdLevel_2').attr('class', 'ywz_zhuce_huixian'); $('#pwdLevel_3').attr('class', 'ywz_zhuce_huixian'); } function Medium() { $('#pwdLevel_1').attr('class', 'ywz_zhuce_hongxian'); $('#pwdLevel_2').attr('class', 'ywz_zhuce_hongxian2'); $('#pwdLevel_3').attr('class', 'ywz_zhuce_huixian'); } function Tough() { $('#pwdLevel_1').attr('class', 'ywz_zhuce_hongxian'); $('#pwdLevel_2').attr('class', 'ywz_zhuce_hongxian2'); $('#pwdLevel_3').attr('class', 'ywz_zhuce_hongxian3'); } function checkPassword(pwdinput) { var maths, smalls, bigs, corps, cat, num; var str = $(pwdinput).val() var len = str.length; var cat = /.{16}/g if (len == 0) return 1; if (len > 16) { $(pwdinput).val(str.match(cat)[0]); } cat = /.*[\u4e00-\u9fa5]+.*$/ if (cat.test(str)) { return -1; } cat = /\d/; var maths = cat.test(str); cat = /[a-z]/; var smalls = cat.test(str); cat = /[A-Z]/; var bigs = cat.test(str); var corps = corpses(pwdinput); var num = maths + smalls + bigs + corps; if (len < 6) { return 1; } if (len >= 6 && len <= 8) { if (num == 1) return 1; if (num == 2 || num == 3) return 2; if (num == 4) return 3; } if (len > 8 && len <= 11) { if (num == 1) return 2; if (num == 2) return 3; if (num == 3) return 4; if (num == 4) return 5; } if (len > 11) { if (num == 1) return 3; if (num == 2) return 4; if (num > 2) return 5; } } function corpses(pwdinput) { var cat = /./g var str = $(pwdinput).val(); var sz = str.match(cat) for (var i = 0; i < sz.length; i++) { cat = /\d/; maths_01 = cat.test(sz[i]); cat = /[a-z]/; smalls_01 = cat.test(sz[i]); cat = /[A-Z]/; bigs_01 = cat.test(sz[i]); if (!maths_01 && !smalls_01 && !bigs_01) { return true; } } return false; } </script> </form>
