本文实例为大家分享了JS正则表达式验证密码强度的具体代码,供大家参考,具体内容如下
代码1:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <style type="text/css"> #dv{ width: 300px; height:200px; position: absolute; left:300px; top:100px; } .strengthLv0 { height: 6px; width: 120px; border: 1px solid #ccc; padding: 2px; } .strengthLv1 { background: red; height: 6px; width: 40px; border: 1px solid #ccc; padding: 2px; } .strengthLv2 { background: orange; height: 6px; width: 80px; border: 1px solid #ccc; padding: 2px; } .strengthLv3 { background: green; height: 6px; width: 120px; border: 1px solid #ccc; padding: 2px; } </style> <body> <div id="dv"> <label for="pwd">密码</label> <input type="text" id="pwd" maxlength="16"><!--课外话题--> <div> <em>密码强度:</em> <em id="strength"></em> <div id="strengthLevel" class="strengthLv0"></div> </div> </div> <script src="/UploadFiles/2021-04-02/common.js">优化代码2:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> </head> <style type="text/css"> #dv{ width: 300px; height:200px; position: absolute; left:300px; top:100px; } .strengthLv0 { height: 6px; width: 120px; border: 1px solid #ccc; padding: 2px; } .strengthLv1 { background: red; height: 6px; width: 40px; border: 1px solid #ccc; padding: 2px; } .strengthLv2 { background: orange; height: 6px; width: 80px; border: 1px solid #ccc; padding: 2px; } .strengthLv3 { background: green; height: 6px; width: 120px; border: 1px solid #ccc; padding: 2px; } </style> <body> <div id="dv"> <label for="pwd">密码</label> <input type="text" id="pwd" maxlength="16"><!--课外话题--> <div> <em>密码强度:</em> <em id="strength"></em> <div id="strengthLevel" class="strengthLv0"></div> </div> </div> <script src="/UploadFiles/2021-04-02/common.js">/** * 获取指定标签对象 * @param id 标签的id属性值 * @returns {Element}根据id属性值返回指定标签对象 */ function my$(id) { return document.getElementById(id); }以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
