最近接到這樣一個需求滑塊進(jìn)度與輸入框為一致,默認(rèn)值為80,最小不能小于30,最大為100，怎么實現(xiàn)這個聯(lián)動效果呢，下面小編給大家分享下基于vue+Ant?Design進(jìn)度條滑塊與input聯(lián)動效果的實現(xiàn)，感興趣的朋友跟隨小編一起看看吧

需求:滑塊進(jìn)度與輸入框為一致,默認(rèn)值為80,最小不能小于30,最大為100

子組件:

<template>
  <div class="progress-box">
    <div
      ref="slider"
      class="slider"
    >
      <div
        class="process"
        :style="{ width }"
      ></div>
      <div
        ref="trunk"
        class="thunk"
        :style="{ left }"
      >
        <div class="block"></div>
      </div>
    </div>
    <div>

      type: Number,
      default: 0

  data() {
    return {
      slider: null, // 滾動條DOM元素
      thunk: null, // 拖拽DOM元素
      per: Math.max(this.sliderMin, this.value) // 當(dāng)前值
    }
  },
  computed: {
    // 設(shè)置一個百分比，提供計算slider進(jìn)度寬度和trunk的left值
    scale() { // 百分比

    },

      if (this.slider) { // 設(shè)置進(jìn)度激活的寬度
        return (this.slider.offsetWidth * this.scale) + 'px'
      } else {

      }
    },
    left() { // trunk left = slider進(jìn)度width + trunk寬度/2
      if (this.slider) { // 設(shè)置圓點所在的位置
        return (this.slider.offsetWidth * this.scale) - this.thunk.offsetWidth / 2 + 'px'
      } else {
        return 0 + 'px'
      }
    }
  },
  // 渲染到頁面的時候
  mounted() {
    this.slider = this.$refs.slider
    this.thunk = this.$refs.trunk
    const _this = this
    this.thunk.onmousedown = function(e) {
      const width = parseInt(_this.width)
      const disX = e.clientX
      document.onmousemove = function(e) {
        // 拖拽的時候獲取的新width
        const newWidth = (e.clientX - disX + width)
        // 拖拽的時候得到新的百分比
        const scale = newWidth / _this.slider.offsetWidth
        _this.per = Math.ceil((_this.sliderMax) * scale)// 對一個數(shù)進(jìn)行上取整把小數(shù)轉(zhuǎn)為整數(shù)(0.3=>30)
        _this.per = Math.max(_this.per, _this.sliderMin)
        _this.per = Math.min(_this.per, _this.sliderMax)
        _this.$emit('input', _this.per)
      }
      document.onmouseup = function() {

補(bǔ)充知識

ant-design-vue 動態(tài)添加input行及動態(tài)校驗

這里涉及到動態(tài)input表單校驗我僅給自己記錄一下

<!-- 動態(tài)添加行 -->
   <a-form-model-item
       :wrapper-col="newWrapper"
       style="padding-left:63px;padding-right:40px;"
       v-for="(item, index) in form.information"
       :key="item.key"
       >
       <a-form-model-item class="fl" :prop="'information.' + index + '.name'"
       :rules="{
           required: true,
           message: '店鋪名不能為空',
           trigger: ['blur','change'],
       }">
           <a-input
               v-model.trim="form.information[index].name"
               placeholder="請輸入店鋪名稱"
               style="margin-right: 1%"
           />
       </a-form-model-item>
       <a-form-model-item class="fl" :prop="'information.' + index + '.address'"
       :rules="{
           required: true,
           message: '店鋪地址不能為空',
           trigger: ['blur','change'],
       }">
           <a-input
               v-model.trim="form.information[index].address"
               placeholder="請輸入店鋪地址"
               style="margin-right: 1%"
           />
       </a-form-model-item>
       <a-form-model-item class="fl" :prop="'information.' + index + '.storeManagerName'"
       :rules="{
           required: true,
           message: '店長姓名不能為空',
           trigger: ['blur','change'],
       }">
           <a-input
               v-model.trim="form.information[index].storeManagerName"
               placeholder="請輸入店長姓名"
               style="margin-right: 1%"
           />
       </a-form-model-item>
       <a-form-model-item class="fl" style="margin-right: 3%;" :prop="'information.' + index + '.storeManagerPhone'"
       :rules="[{required: true,message: '店長手機(jī)不能為空',trigger: ['blur','change']},
               {validator: mobilephoneValidate,trigger: ['blur','change'] }]"          
       >
           <a-input
               v-model.trim="form.information[index].storeManagerPhone"
               placeholder="請輸入店長手機(jī)號"
           />
       </a-form-model-item>
       <a
       v-if="form.information.length > 1"
       :disabled="form.information.length === 1"
       @click="removeRows(item)"
       >刪除</a>
   </a-form-model-item>

添加刪除的方法

// 動態(tài)刪除添加輸入行
        removeRows(item) {
            let index = this.form.information.indexOf(item);
            if (index !== -1) {
                this.form.information.splice(index, 1);
            }
        },
        addRows() {
            this.form.information.push({
                name: '',
                address: '',
                storeManagerName: '',
                storeManagerPhone: '',
                key: Date.now(),
            });
        },

手機(jī)號或者其他單獨的表單校驗寫在methods里

// 動態(tài)添加行 店長手機(jī)號驗證
        testMobilephone: function (str) {
            const regex = /^1[3456789]\d{9}$/
            if (!regex.test(str)) {
            return false
            } else {
            return true
            }
        },
        mobilephoneValidate (rule, value, callback) {
        // 主要就是添加一個對undefined和空串的判斷
        if (typeof (value) === 'undefined' || value === '') {
            callback()
            } else {
                if (!this.testMobilephone(value)) {
                callback(new Error('請輸入正確手機(jī)格式'))
                }
                callback()
            }
        },

這里information數(shù)組在data里寫上一組空對象是為了保證有一組input行顯示出來不寫input行則會隱藏掉
