VUE实现移动端列表筛选功能

最近兴趣所致，打算使用vant搭建一个webapp，由于需要使用列表筛选，没有找到合适组件，于是写了一个简单的功能，权当记录。

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\">确定</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,

     ]
    },
    {
     name: \"口味\",
     value: 2,
     isShow: false,
     multiple: true,
     data: [

      { name: \"养生\", value: 3, selected: false }
     ]
    },
    {
     name: \"适合人群\",
     value: 3,
     isShow: false,
     multiple: true,
     data: [
      { name: \"老人\", value: 1, selected: false },
      { name: \"婴儿\", 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: \"做过最多\", value: 1, selected: false },
      { name: \"点赞最多\", 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>
