vue中el-autocomplete与el-select的异同

    <el-autocomplete
      v-model="value"
      :fetch-suggestions="querySearchAsync"
      placeholder="请输入内容"
    ></el-autocomplete>
    
    export default {
     data () {
         return {
           value: ''
         }
     },
     methods: {
        querySearchAsync (queryString, cb) {
          setTimeout(() => {
            cb([{value: '答案cp3'}])
          }, 200)
        }
    }

    <el-select
      v-model="value"
      filterable
      remote
      reserve-keyword
      placeholder="请输入关键词"
      :remote-method="remoteMethod"
      :loading="reqLoading"
    >
      <el-option v-for="item in options" :key="item.value" :label="item.label" :value="item.value"></el-option>
    </el-select>
    
    export default {
     data () {
         return {
           value: '',
           reqLoading: false,
           options: []
         }
     },
     methods: {
        remoteMethod (query) {
          if (query !== '') {
            this.reqLoading = true
            setTimeout(() => {
              this.reqLoading = false
              this.options = [{label: '答案cp3',value: '答案cp3'}]
            }, 200)
          } else {
            this.options = []
          }
        }
    }
