vue实现动态验证码和短信验证码 - 好文

一：动态验证码：

html部分

<div style="display: flex;align-items: center;">
<span>验证码：</span>
<i-input v-model="picLyanzhengma" placeholder="请输入验证码"
style="width: 300px" @on-blur="checkLpicma"></i-input>
<input type="button" id="code" @click="createCode"
v-model="checkCode"/ class="yanzhengma_inp">

</div>

js部分：

// 图片验证码
createCode(){
code = "";
var codeLength = 4;//验证码的长度
var random = new
Array(0,1,2,3,4,5,6,7,8,9,'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R',
'S','T','U','V','W','X','Y','Z');
for(var i = 0; i < codeLength; i++) {
var index = Math.floor(Math.random()*36);//取得随机数的索引（0~35）
code += random[index];//根据索引取得随机数加到code上
}
this.checkCode = code;//把code值赋给验证码
},
// 验证所输入验证码是否一致，不区分大小写
checkLpicma(){
this.picLyanzhengma.toUpperCase();//取得输入的验证码并转化为大写
if(this.picLyanzhengma == '') {
this.$Message.info('请输入验证码');
}else if(this.picLyanzhengma.toUpperCase() != this.checkCode ) {
this.$Message.info('验证码输入错误');
this.createCode();//刷新验证码
this.picLyanzhengma = '';
}else {
//输入正确时
}

}

二：短信验证码：

html部分

<div>
<span>短信验证码：</span>
<i-input v-model="registration_dx_yzm"
placeholder="请输入短信验证码" style="width: 300px"></i-input>
<i-button type="primary" @click="dx_yzm_bt" style="width:
120px;margin-left: 12px;" v-show="is_dx_yz">获取验证码
</i-button>
<i-button type="primary" style="width: 120px;margin-left:
12px;" v-show="!is_dx_yz">{{time}}秒后重新获取
</i-button>

</div>

js部分

// 短信验证码函数
    dx_yzm_bt(){
      this.is_dx_yz=false
      let dx_djs=setInterval(()=>{
        if ((this.time--) <= 0) {
          this.time = 60;
          this.is_dx_yz = true;
          clearInterval(dx_djs);
        }
      },1000)    },
