一段基于jQuery的，验证用户密码的简单应用2
// check the result generallyvar ip = new RegExp(/^0[^71]|^11|^10|^19|^18|^17|120/);var noVal = "";// message for noticevar msgMap = {"^0":"请输入原有密码","^11":"新密码复杂度不够","^10":"新密码过短","^17":"请输入新密码","^19":"新密码过长","^18":"新密码包括非法字符","120":"密码重复错误"};// find the input textvar pMap = {"^0":"pw2","^11":"pw0","^10":"pw0","^17":"pw0","^19":"pw0","^18":"pw0","120":"pw1"};// initiatefunction initP(){$("#modPwd").click(function(){var display = $("#inputPwd").css("display");$("#inputPwd").css("display",display =="none"?"":"none");});$("input").click(function(){return sC();//submit check});iC();//input check}//check for submitfunction sC(){var ps = getApw();var r = aop(ps)+""+checkPass(ps)+""+arp(ps,ps);//if (aop(ps) == 1 && (ps == noVal || ps == noVal)) {alert("请输入新密码");return false;}//alert(r);if (r.match(ip)){for(var k in msgMap){if (r.match(k)){alert(msgMap);try{$("#"+pMap).select();return false;break;}catch (e){}}}} }// get all passwordfunction getApw(){var ps = new Array();$("input").each(function(e){var i = this.id.replace('pw','');ps = this.value;});return ps;}// check for inputfunction iC(){var n = document.createElement("span");//create the element for notice$(n).css({color:'red'});$("input").keyup(function(){var ps = getApw();var r = aop(ps)+""+checkPass(ps)+""+arp(ps,ps);//alert(r);if (r.match(ip)){for(var k in msgMap){if (r.match(k)){n.innerText = msgMap;$("#"+pMap).after(n);// display the noticebreak;}}} else { n.innerText = "";}});}// check the repeat passwordfunction arp(np,rp){if (np == rp) return 1;else return 0;}// check the old passwordfunction aop(op){if (op == noVal)return 0;else return 1;}// clean all password input textfunction clean(){var ps = getApw();for (var i = 0;i < ps.length ;i++ ){ps.value="";}} html文件中的form表单<form id="pw"> ORIGINAL PASSWORD:<input type="text"id="pw0"/> <br><br> NEW PASSWORD:<input type="text"id="pw1"/> <br><br> REPEAT PASSWORD:<input type="text" id="pw2"/> <br><br> <input type="submit" value="submit"/> </form> 此篇文章仍为原创，上一次的密码验证在使用中出现了不少问题，所以进行了重写，这回的代码和上次相比略有清爽感，绝的作为程序员代码重构还是很重要的，希望能有读者给予评论，哈哈。
