這篇文章主要介紹了VUE實(shí)現(xiàn)移動(dòng)端列表篩選功能，非常不錯(cuò)，具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

最近興趣所致，打算使用vant搭建一個(gè)webapp，由于需要使用列表篩選，沒有找到合適組件，于是寫了一個(gè)簡單的功能，權(quán)當(dāng)記錄。

效果如下：

HTML:

<div class="filterbar">
   <div class="filterbar-title">
    <ul class="title-ul">
     <li
      :class="{'title-li':true, 'current': item.isShow}"
      v-for="(item, index) in barMenus"
      :key="index"
     >
      <span @click="handerClickMenu(item)">
       {{item.name}}
       <van-icon :name="item.isShow ? 'arrow-up' :'arrow-down'" />
      </span>
      <div class="filterbar-content" v-on:click.stop v-if="item.isShow">
       <ul class="content-ul">
        <li
         v-for="(child, number) in item.data"
         :key="number"
         :class="{'current': child.selected}"
         @click="handerClickContent(item, child)"
        >
         {{child.name}}
         <van-icon v-if="child.selected" name="success" />
        </li>
       </ul>
       <div class="button-div" v-if="item.multiple">
        <van-button plain type="default" @click="handerClear(item)">清空</van-button>
        <van-button type="info" @click="search">確定</van-button>
       </div>
      </div>
     </li>
    </ul>
   </div>
   <div class="bg-filterbar" v-if="isBgFilterbarShow" @click="handerClickMenu"></div>
  </div>

CSS:

.filterbar {
  position: fixed;
  z-index: 2;
  left: 0;
  top: 3.1em;
  width: 100%;
  background-color: #fff;
  height: 2em;

  .bg-filterbar {
   position: fixed;
   width: 100%;
   height: 100%;
   background-color: black;
   opacity: 0.2;
   z-index: 1;
   left: 0;
   top: 4.2em;
  }
  .filterbar-title {
   width: 100%;
   .title-ul {
    height: 1.4em;
    margin-bottom: 0.5em;
    border-bottom: 1px solid #eee;
   }
   ul .title-li {
    width: 24%;
    float: left;
    text-align: center;
    font-size: 0.9em;

    .filterbar-content {
     position: absolute;
     left: 0;
     width: 100%;
     padding: 0.5em;
     background-color: #fff;
     z-index: 2;
     top: 1.24em;
    }
    .content-ul li {
     text-align: left;
     color: #111;
     font-weight: 400;
     padding-left: 1.5em;
     padding-top: 0.7em;
    }
    .content-ul .current {
     color: #1989fa;
    }
   }
   ul .current {
    color: #1989fa;
    font-weight: 600;
   }
   ul:after {
    content: "";
    display: block;
    clear: both;
   }
   .content-ul .van-icon {
    float: right;
    margin-right: 2.5em;
   }
   ul .van-icon {
    vertical-align: middle;
   }
  }
  .button-div {
   margin-top: 1.5em;
   text-align: center;

   button {
    width: 48%;
    float: left;
   }
   .van-button {
    height: 3em;
    line-height: 3em;
    font-size: 1em;
    font-weight: 400;
   }
  }
 }

JS:

<script>
export default {
 data() {
  return {
   barMenus: [
    {
     name: "菜系",
     value: 1,
     isShow: false,
     multiple: true,
     data: [
      { name: "川菜", value: 1, selected: false },
      { name: "粵菜", value: 2, selected: false },
      { name: "湘菜", value: 3, selected: false },
      { name: "蘇菜", value: 4, selected: false },
      { name: "閩菜", value: 5, selected: false },
      { name: "徽菜", value: 6, selected: false },
      { name: "浙菜", value: 7, selected: false },
      { name: "魯菜", value: 8, selected: false }
     ]
    },
    {
     name: "口味",
     value: 2,
     isShow: false,
     multiple: true,
     data: [
      { name: "清淡", value: 1, selected: false },
      { name: "麻辣", value: 2, selected: false },
      { name: "養(yǎng)生", value: 3, selected: false }
     ]
    },
    {
     name: "適合人群",
     value: 3,
     isShow: false,
     multiple: true,
     data: [
      { name: "老人", value: 1, selected: false },
      { name: "嬰兒", value: 2, selected: false },
      { name: "小孩", value: 2, selected: false },
      { name: "病人", value: 2, selected: false }
     ]
    },
    {
     name: "排序",
     value: 4,
     isShow: false,
     multiple: false,
     data: [
      { name: "做過最多", value: 1, selected: false },
      { name: "點(diǎn)贊最多", value: 2, selected: false }
     ]
    }
   ]
  };
 },

 computed: {
  isBgFilterbarShow: {
   get() {
    let isBgShow = false;
    this.barMenus.forEach(function(currentValue, index, arr) {
     if (currentValue.isShow) {
      isBgShow = true;
     }
    });
    return isBgShow;
   }
  }
 },

 methods: {
  search() {
   this.handerClose();
  },

  handerClose() {
   this.barMenus.forEach(function(currentValue, index, arr) {
    currentValue.isShow = false;
   });
  },

  handerClickMenu(item) {
   if (!item) {
    return;
   }

   this.barMenus.forEach(function(currentValue, index, arr) {
    if (currentValue.value == item.value) {
     currentValue.isShow = !currentValue.isShow;
    } else {
     currentValue.isShow = false;
    }
   });
  },

  handerClickContent(item, child) {
   if (!item.multiple) {
    this.handerClear(item);
    this.handerClose(item);
   }

   child.selected = !child.selected;
  },

  handerClear(item) {
   item.data.forEach(function(currentValue, index, arr) {
    currentValue.selected = false;
   });
  }
 }
};
</script>

參數(shù)說明：

name：篩選項(xiàng)顯示名稱
value：篩選項(xiàng)code
isShow：是否顯示
multiple: 是否多選，為true時(shí)會(huì)有清空和確定功能按鈕
data：篩選列表項(xiàng)
