vue滑块滑动校验，兼容移动端/pc端

效果图 

一：可以将样式写到组件中

1.html部分

<template>
  <div class="drag" ref="dragDiv">
    <div class="drag_bg"></div>
    <div class="drag_text">{
   
   { confirmWords }}</div>
    
    <div
      ref="moveDiv"
      @mousedown="mouseDownFn" @touchstart="mouseDownFn"
      :class="{ handler_ok_bg: confirmSuccess }"
      class="handler handler_bg"
      style="position: absolute; top: 0px; left: 0px"
    ></div>
  </div>
</template>

 2.js部分

<script>
export default {
  data() {
    return {
      beginClientX: 0 /*距离屏幕左端距离*/,
      mouseMoveState: false /*触发拖动状态  判断*/,
      maxWidth: "" /*拖动最大宽度，依据滑块宽度算出来的*/,
      confirmWords: "请按住滑块，拖动到最右边" /*滑块文字*/,
      confirmSuccess: false /*验证成功判断*/,
    };
  },
    mounted() {
      this.maxWidth =this.$refs.dragDiv.clientWidth - this.$refs.moveDiv.clientWidth;
      document.getElementsByTagName("html")[0].addEventListener("mousemove", this.mouseMoveFn);
      document.getElementsByTagName("html")[0].addEventListener("mouseup", this.moseUpFn);
      document.getElementsByTagName("html")[0].addEventListener("touchmove",this.mouseMoveFn );
      document.getElementsByTagName("html")[0].addEventListener("touchend", this.moseUpFn);
  },
  methods: {
    //mousedown 事件
    mouseDownFn: function (e) {
      if (!this.confirmSuccess) {
        e.preventDefault && e.preventDefault(); //阻止文字选中等 浏览器默认事件
        this.mouseMoveState = true;
        this.beginClientX = e.clientX?e.clientX:e.changedTouches[0].clientX;

      }
    },
    //验证成功函数
    successFunction() {
      this.confirmSuccess = true;
      this.confirmWords = "验证通过";
      if (window.addEventListener) {
        document.getElementsByTagName("html")[0].removeEventListener("mousemove", this.mouseMoveFn);
        document.getElementsByTagName("html")[0].removeEventListener("mouseup", this.moseUpFn);
        document.getElementsByTagName("html")[0].removeEventListener("touchmove",this.mouseMoveFn );
        document.getElementsByTagName("html")[0].removeEventListener("touchend", this.moseUpFn);

      } else {
        document.getElementsByTagName("html")[0].removeEventListener("mouseup", () => {});
        document.getElementsByTagName("html")[0].removeEventListener("touchend", () => {});
      }
      document.getElementsByClassName("drag_text")[0].style.color = "#fff";
      document.getElementsByClassName("handler")[0].style.left =this.maxWidth + "px";
      document.getElementsByClassName("drag_bg")[0].style.width =this.maxWidth + "px";
    },
    //mousemove事件
    mouseMoveFn(e) {
      if (this.mouseMoveState) {
        let numX=e.clientX?e.clientX:e.changedTouches[0].clientX
        let width =  numX - this.beginClientX;
        if (width > 0 && width <= this.maxWidth) {
          document.getElementsByClassName("handler")[0].style.left =width + "px";
          document.getElementsByClassName("drag_bg")[0].style.width = width + "px";
        } else if (width > this.maxWidth) {
          this.successFunction();
        }
      }
    },
    //mouseup事件
    moseUpFn(e) {
      this.mouseMoveState = false;
      let numX=e.clientX?e.clientX:e.changedTouches[0].clientX
      var width =  numX- this.beginClientX;
      if (width < this.maxWidth) {
        document.getElementsByClassName("handler")[0].style.left = 0 + "px";
        document.getElementsByClassName("drag_bg")[0].style.width = 0 + "px";
      }
    },
  },

};
</script>

3.css部分

二：在页面中调用

<template>
 <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
            <el-form-item label="滑动验证" prop="slider">
                <div><slider ref="slider"></slider></div>
            </el-form-item>
</el-form>
</template>
<script>
// 调用组件
import slider from '../../components/slider.vue'
export default {
    data(){
        return{
            ruleForm:{},
    },
    components: {
        slider
    },
    methods: {
        submitForm() {
            if(this.$refs['slider']) {
                // 未通过验证时，提示错误信息并返回
                if (!this.$refs['slider'].confirmSuccess) {
                    console.log(this.$refs['slider'].confirmSuccess)
                    this.$message.error("请拖动滑块验证");
                    return
                }else{
                    this.$message.success("验证成功，可提交");
                    console.log(this.$refs['slider'].confirmSuccess)
           
                }
            }
        },
    }
}
</script>
