一、前端检查 案例

 <title> 密码强度检测 </title>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 <style type="text/css">
 input{float: left; font-size: 14px; width: 250px; height: 25px; border: 1px solid #ccc; padding-left: 10px;}
 #tips{float: left; font-size: 12px; width: 400px; height: 25px; margin: 4px 0 0 20px;}
 #tips span{float: left; width: 40px; height: 20px; color: #fff; overflow:hidden; margin-right: 10px; background: #D7D9DD; line-height:20px; text-align: center; }

 <body>
 <input type="text" id="password" value="" maxlength="16" />
 <div id="tips">
 <span>弱</span>
 <span>中</span>
 <span>强</span>
 <span>很强</span>
 </div>
</body>
 <script type="text/javascript">
 var password = document.getElementById("password"); //获取文本框的对象

  var index = checkPassWord(this.value);
  for(var i = 0; i <spanDoms.length; i++){

   if(index){//0 代表false 其余代表true

   }
  }
 }
 //校验密码强度
 function checkPassWord(value){
  // 0： 表示第一个级别 1：表示第二个级别 2：表示第三个级别
  // 3： 表示第四个级别 4：表示第五个级别
  var modes = 0;
  if(value.length < 6){//最初级别

二、后端检查案例

三、vue专项检查案例

http://www.datouwang.com/jiaoben/973.html

主要代码：

/* DaTouWang URL: www.datouwang.com */
var app = new Vue({
  el: "#app",

  data: {
    password: null,
    password_length: 0,
    typed: false,
    contains_lovercase: false,
    contains_number: false,
    contains_uppercase: false,
    valid_password_length: false,
    valid_password: false
  },

  methods: {
    p_len: function() {
      this.password_length = this.password.length;
      if (this.password_length > 7) {
        this.valid_password_length = true;
      } else {
        this.valid_password_length = false;
      }

      if (this.password_length > 0) {
        this.typed = true;
      } else {
        this.typed = false;
      }

      this.contains_lovercase = /[a-z]/.test(this.password);
      this.contains_number = /\d/.test(this.password);
      this.contains_uppercase = /[A-Z]/.test(this.password);

      // Check if the password is valid
      if (this.contains_lovercase == true && this.contains_number == true) {
        this.valid_password = false;
        if (
          this.contains_uppercase == true &&
          this.valid_password_length == true
        )
          this.valid_password = true;
      } else {
        this.valid_password = false;
      }
    }
  }
});

　　

四、vue实际应用：

<style lang="css" scoped>
 #tips{float: left; font-size: 12px; width: 400px; height: 25px; margin: 4px 0 0 20px;}
 #tips span{float: left; width: 40px; height: 20px; color: #fff; overflow:hidden; margin-right: 10px; background: #D7D9DD; line-height:20px; text-align: center; }
 #tips .s1{background: #F45A68;}/*红色*/
 #tips .s2{background: #fc0;}/*橙色*/
 #tips .s3{background: #cc0;}/*黄色*/
 #tips .s4{background: #14B12F;}/*绿色*/

</style>
<template>
  <div>

    <!-- <sticky class-name="sub-navbar white">
