Vue滑块验证

登陆时加入滑块验证

1、在src\components新建SilderVerify\index.vue文件

<template>
  <div class="silder-range" :class="rangeStatus?'success':''">
    <i @mousedown="rangeMove" :class="rangeStatus?successIcon:startIcon"></i>
    {{rangeStatus?successText:startText}}
  </div>
</template>
<script>
export default {
  props: {
    //成功图标
    successIcon: {
      type: String,
      default: "el-icon-success"
    },
    //成功文字
    successText: {
      type: String,
      default: "验证成功"
    },
    //开始的图标
    startIcon: {
      type: String,
      default: "el-icon-d-arrow-right"
    },
    //开始的文字
    startText: {
      type: String,
      default: "拖动滑块到最右侧"
    }
  },
  name: "SilderVerify",
  data() {
    return {
        rangeStatus:'',
        
    };
  },
  methods: {
    rangeMove(e){
            let ele = e.target;
            let startX = e.clientX;
            let eleWidth = ele.offsetWidth;
            let parentWidth =  ele.parentElement.offsetWidth;
            let MaxX = parentWidth - eleWidth;
            if(this.rangeStatus){//不运行
                return false;
            }
            document.onmousemove = (e) => {
                let endX = e.clientX;
                this.disX = endX - startX;
                if(this.disX<=0){
                    this.disX = 0;
                }
                if(this.disX>=MaxX-eleWidth){//减去滑块的宽度,体验效果更好
                    this.disX = MaxX;
                }
                ele.style.transition = '.1s all';
                ele.style.transform = 'translateX('+this.disX+'px)';
                e.preventDefault();
            }
            document.onmouseup = ()=> {
                if(this.disX !== MaxX){
                    ele.style.transition = '.5s all';
                    ele.style.transform = 'translateX(0)';

          this.$emit("failed", this.rangeStatus);
                    
                }else{
                    this.rangeStatus = true;

          this.$emit("success", this.rangeStatus);
                    
                }
                document.onmousemove = null;
                document.onmouseup = null;
            }
        }
  
  }
};
</script>
<style scoped>
.silder-range{
    background-color: #e3e4e6;
    position: relative;
    transition: 1s all;
    user-select: none;
    color: #333;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 45px; /*no*/
}
.silder-range i{
    position: absolute;
    left: 0;
    width: 60px;/*no*/
    height: 100%;
    color: #919191;
    background-color: #fff;
    border: 1px solid #bbb;
    cursor: pointer;
    display: flex;
    justify-content: center;
    align-items: center;
}
.silder-range.success{
    background-color: #7AC23C;
    color: #fff;
}
.silder-range.success i{
    color: #7AC23C;
}
</style>

2、在登录页面引入组件     

import SilderVerify from '@/components/SilderVerify' 


 components:{
    SilderVerify
  }

3、加表单验证

    status: [{ validator: validatestatus, trigger: "change" }]

    const validatestatus = (rule, value, callback)=> {
      if (!value) {
        callback(new Error('请拖动滑块完成验证'))
      } else {
        callback()
      }
    }

4、密码框下方使用组件，success为成功后回调，failed为失败后回调

      <el-form-item prop="status">  
        <silder-verify @success="handleSuccess" @failed="handleError"></silder-verify >
      </el-form-item>

    handleSuccess(){
      this.loginForm.status = true
      this.$refs.loginForm.validateField("status")
    }

5、效果展示
