1.vue密码校验：

data() {
  const equalToPassword = (rule, value, callback) => {
    if (this.user.newPassword !== value) {
      callback(new Error("两次输入的密码不一致"));
    } else {callback();}
  };
  return {
    user: {
      oldPassword: undefined,
      newPassword: undefined,
      confirmPassword: undefined,
    },
    // 表单校验
    rules: {
      oldPassword: [
        { required: true, message: "旧密码不能为空", trigger: "blur" },
      ],
      newPassword: [
        { required: true, message: "新密码不能为空", trigger: "blur" },
        {
          validator: (rule, value, callback) => {
            const reg = /(?=.*\d)(?=.*[a-zA-Z])(?=.*[^a-zA-Z0-9]).{6,16}/;
            if (reg.test(value)) { callback();} else {
              callback(new Error());
            }
          },
          message: "密码必须由数字、字母、特殊字符组合,请输入6-16位",trigger: "blur",
        },
      ],
      confirmPassword: [
        { required: true, message: "确认密码不能为空", trigger: "blur" },
        { required: true, validator: equalToPassword, trigger: "blur" },
      ],
    },
  };
},

2.js密码校验：

let reg = /^(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[0-9])(?=.*?[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]).{8,18}$/;
const password="1653#Ww250"
if(reg.test(password)){
console.log(`${password}：长度为${password.length}通过正则表达式密码校验`);
}else{
console.error(`${password}：${password.length}未通过正则表达式密码校验`);

}
