vue 底部footer导航组件问题

vue底部footer导航组件

底部导航一定要用路径!!! 贼关键

举个例子：

你随便定义了一个变量, flag : 0 跳转首页, falg:1,跳转我的,

底部导航的组件不可能全项目使用, 点击我的页面  这个时候flag 已经变成了1,

从我的页面进入详情页,从详情页返回的时候,虽然路由没有变,但是flag 已经初始化成了0,

我们的判断条件没办法自定义,每次从详情页返回的时候都会被初始化,

!!! 判断一定要用路径

$route.path

<template>
  <div class="footer">
  <div class="costlist1" @click="choicestate('/dashboard/analysis')">
      <img class="costurl" v-if="$route.path==='/dashboard/analysis'" src="../../assets/img/bot-apply0.png" />
      <img class="costurl" v-else src="../../assets/img/bot-apply1.png" />
      <div
        class="costname"
        :style="{color:$route.path==='/dashboard/analysis'?'rgb(18,139,232)':'rgba(0, 0, 0, 0.65)'}"
      >首页</div>
    </div>
    <div class="costlist1" @click="choicestate('/dashboard/toexamine')">
      <a-badge :count="this.$store.state.applynum">
        <img class="costurl" v-if="$route.path==='/dashboard/toexamine'" src="../../assets/img/1.png" />
        <img class="costurl" v-else src="../../assets/img/0.png" />
      </a-badge>
      <div
        class="costname"
        :style="{color:$route.path==='/dashboard/toexamine'?'rgb(18,139,232)':'rgba(0, 0, 0, 0.65)'}"
      >审核</div>
    </div>
    <div class="costlist1" @click="choicestate('/dashboard/mine')">
      <img class="costurl" v-if="$route.path==='/dashboard/mine'" src="../../assets/img/mine11.png" />
      <img class="costurl" v-else src="../../assets/img/mine12.png" />
      <div
        class="costname"
        :style="{color:$route.path==='/dashboard/mine'?'rgb(18,139,232)':'rgba(0, 0, 0, 0.65)'}"
      >我的</div>
  </div>
  </div>
</template>

<script>
export default {
  name: 'layoutfooter',
  data() {
    return {
      applynum: 0,
      reimbnum: 0,
      wgtver: ''
    }
}
  methods: {
    choicestate(path) {
      this.$router.push(path)
    }
  }
}
</script>

<style lang="scss" scoped>
.footer {
  position: fixed;
  bottom: 0;
  width: 100%;
  display: flex;
  justify-content: space-between;
  height: 58px;
  background: #eff0f6;
  align-items: center;
  .costlist1 {
    display: flex;
    flex-direction: column;
    justify-content: center;
    flex: 1;
    height: 58px;
    align-items: center;
    img {
      width: 20px;
      height: 22px;
    }
    .costname {
      text-align: center;
    }
  }
}
.ant-carousel >>> .slick-slide {
  text-align: center;
  height: 160px !important;
  line-height: 160px;

vue抽取的footer组件,可复用

<template>
  <div class="app-foot">
    {{footermsgcopyright}}
    <span class="source">{{footermsgname}}</span>
  </div>
</template>

<script>
export default {
  name: 'appfoot',
  data() {
    return {
      // 版权说明的文字
      footermsgcopyright: 'copyright © 2020-2021 xxxx平台 - powered by ',
      // 单位
      footermsgname: 'xxxx实验室'
    }
  }
}
</script>

<style scoped>
.app-foot {
  /* footer 固定在页面底部 */
  min-height: 35px;
  background-color: #eeeeee;
  width: 100%;
  font-size: 14px;
  display: flex;
  align-items: center;
  justify-content: center;
}
.source{
  font-weight: 600;
}
</style>

复用时直接调用组件

主页面设定高度时，要把footer的高度空出来，其style可以如下：

<style>
.main-container{
  /*  35 = footer  */
  min-height: calc(100vh - 35px);
}
</style>

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
