标签：el loading return list item input New select

项目场景：

例如：项目中很多情况 用到el-input  el-select单有时间 他会调取浏览器默认保存的用户名密码出来就很不爽，网上找了很多方法没一个靠谱的 ，反正我试了都不行都不能完美解决这个问题。

如图：

问题描我们通常写法如下：

提示：这里以el-select为实例  input同理

<template>
  <el-select
    v-model="value"
    multiple
    filterable
    remote
    reserve-keyword
    placeholder="请输入关键词"
    :remote-method="remoteMethod"
    :loading="loading">
    <el-option
      v-for="item in options"
      :key="item.value"
      :label="item.label"
      :value="item.value">
    </el-option>
  </el-select>
</template>

<script>
  export default {
    data() {
      return {
        options: [],
        value: [],
        list: [],
        loading: false,
        states: ["Alabama", "Alaska", "Arizona",
        "Arkansas", "California", "Colorado",
        "Connecticut", "Delaware", "Florida",
        "Georgia", "Hawaii", "Idaho", "Illinois",
        "Indiana", "Iowa", "Kansas", "Kentucky",
        "Louisiana", "Maine", "Maryland",
        "Massachusetts", "Michigan", "Minnesota",
        "Mississippi", "Missouri", "Montana",
        "Nebraska", "Nevada", "New Hampshire",
        "New Jersey", "New Mexico", "New York",
        "North Carolina", "North Dakota", "Ohio",
        "Oklahoma", "Oregon", "Pennsylvania",
        "Rhode Island", "South Carolina",
        "South Dakota", "Tennessee", "Texas",
        "Utah", "Vermont", "Virginia",
        "Washington", "West Virginia", "Wisconsin",
        "Wyoming"]
      }
    },
    mounted() {
      this.list = this.states.map(item => {
        return { value: `value:${item}`, label: `label:${item}` };
      });
    },
    methods: {
      remoteMethod(query) {
        if (query !== '') {
          this.loading = true;
          setTimeout(() => {
            this.loading = false;
            this.options = this.list.filter(item => {
              return item.label.toLowerCase()
                .indexOf(query.toLowerCase()) > -1;
            });
          }, 200);
        } else {
          this.options = [];
        }
      }
    }
  }
</script>

解决方案：

例如：新建一个el-input放在 上线出现输入框的上面（<el-input  style="position: absolute;z-index: -999"></el-input>）
代码如下：

<template>
  <el-select
    v-model="value"
    multiple
    filterable
    remote
    reserve-keyword
    placeholder="请输入关键词"
    :remote-method="remoteMethod"
    :loading="loading">
    <el-option
      v-for="item in options"
      :key="item.value"
      :label="item.label"
      :value="item.value">
    </el-option>
  </el-select>
<!--这里就是解决问题的代码了-->
<el-input  style="position: absolute;z-index: -999"></el-input>
</template>

<script>
  export default {
    data() {
      return {
        options: [],
        value: [],
        list: [],
        loading: false,
        states: ["Alabama", "Alaska", "Arizona",
        "Arkansas", "California", "Colorado",
        "Connecticut", "Delaware", "Florida",
        "Georgia", "Hawaii", "Idaho", "Illinois",
        "Indiana", "Iowa", "Kansas", "Kentucky",
        "Louisiana", "Maine", "Maryland",
        "Massachusetts", "Michigan", "Minnesota",
        "Mississippi", "Missouri", "Montana",
        "Nebraska", "Nevada", "New Hampshire",
        "New Jersey", "New Mexico", "New York",
        "North Carolina", "North Dakota", "Ohio",
        "Oklahoma", "Oregon", "Pennsylvania",
        "Rhode Island", "South Carolina",
        "South Dakota", "Tennessee", "Texas",
        "Utah", "Vermont", "Virginia",
        "Washington", "West Virginia", "Wisconsin",
        "Wyoming"]
      }
    },
    mounted() {
      this.list = this.states.map(item => {
        return { value: `value:${item}`, label: `label:${item}` };
      });
    },
    methods: {
      remoteMethod(query) {
        if (query !== '') {
          this.loading = true;
          setTimeout(() => {
            this.loading = false;
            this.options = this.list.filter(item => {
              return item.label.toLowerCase()
                .indexOf(query.toLowerCase()) > -1;
            });
          }, 200);
        } else {
          this.options = [];
        }
      }
    }
  }
</script>
