js，vue，element 密码设置密码最小长度8个字符,必须包含数字大小写字母,特殊符号

1.先说一下原生js的几个正则：this.contains_lovercase = /[a-z]/.test(this.password); //小写this.contains_number = /\d/.test(this.password); //数字this.contains_uppercase = /[A-Z]/.test(this.password); //大写var p...

1.先说一下原生js的几个正则：

this.contains_lovercase = /[a-z]/.test(this.password); //小写

this.contains_number = /\d/.test(this.password); //数字

this.contains_uppercase = /[A-Z]/.test(this.password); //大写

var pattern = new RegExp("[`~!@#$^&*()=|{}':;',\\[\\].<>/?~！@#￥……&*（）——|{}【】‘；：”“'。，、？]")

2.在写入vue代码中需要设置一些样式及判断，本人也是参考了网上其他友人的代码，如有冒犯请见谅

html中：

<span v-bind:class="{ valid_password_length: valid_password_length , show_password_length: typed}" class="password_length">{{password_length}}</span>

<path class="tick" v-bind:class="{checked: valid_password }"

d="M10,50 l25,40 l95,-70" />

</svg>

</div>

</div>

<p style="color:red;fontSize:10px">温馨提示：密码最小长度8个字符,必须包含数字大小写字母,特殊符号</p>

<el-button @click="passwordTpl = false">取消</el-button>

<el-button type="primary" @click="passwordTrue">确定</el-button>

</div>

css中：

/* 设置勾号大小 */

.el-checkbox__inner::after {

height: 13px;

left: 8px;

}

/* 设置选择框大小 */

.el-checkbox__inner {

width: 20px;

注意适用的框架，如果不是vue element 可自行改动一下，，核心点在于正则的校验以及长度的校验
