VUE PC端实现滑块验证效果

1.定义自定义组件

<template>
  <div class="jc-component__range">
    <div class="jc-range" :class="rangeStatus?'success':''">
      <i @mousedown="rangeMove" :class="rangeStatus?successIcon:startIcon"></i>
      {{rangeStatus?successText:startText}}
    </div>
  </div>
</template>
<script>
export default {
  props: {
    // 成功之后的函数
    successFun: {
      type: Function
    },
    //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: "拖动滑块至最右端"
    },
    //失败之后的函数
    errorFun: {
      type: Function
    },
    //或者用值来进行监听
    status: {
      type: String
    }
  },
  name: "Silder",
  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)';
                    //执行成功的函数
                    this.errorFun && this.errorFun();
                }else{
                    this.rangeStatus = true;
                    if(this.status){
                        this.$parent[this.status] = true;
                    }
                    //执行成功的函数
                    this.successFun && this.successFun();
                }
                document.onmousemove = null;
                document.onmouseup = null;
            }
        }
  
  }
};
</script>
<style scoped>
    .jc-range{
    width: 262px;
    background-color: #EEEEEE;
    position: relative;
    transition: 1s all;
    user-select: none;
    color: #333;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 45px; /*no*/
    border-radius: 10px;
    color: #999999;
}
.jc-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;
    border-radius: 10px;
}
.jc-range.success{
    background-color: #7AC23C;
    color: #fff;
}
.jc-range.success i{
    background: transparent;
    border: 0;
    color: #fff;
    font-size: 35px;
}
</style>

2.在需要使用的组件内调用组件

<slider status="status" :successFun="这里传递你的函数(成功)" :errorFun="这里传递你的函数(失败)"/>
import slider from '@/components/component/slider.vue'
components:{
    slider
  },
//定义值status
