vue vant ui 教程&注意事项

01

vant 插件PullRefresh下拉刷新 会出现滚动就刷新的情况

常见问题:

1.父级容器不存在overflow：hidden

2.当使用Refresh插件时，如果存在当van-refresh组件的父级overfow-y:scorll 的样式时，选中的滚动条为父级元素，此时当body内部容器撑开页面元素时（也就是body存在滚动条时）

解决方式:

1.给父级容器加上overflow:hidden

2.设置van-refresh组件的父级组件的正确高度，使body的高度不会出现滚动条。

.van-pull-refresh {
     height: 100vh;
     overflow: auto !important;
}

PullRefresh 的内容未填满屏幕时，只有一部分区域可以下拉？默认情况下，下拉区域的高度是和内容高度保持一致的，如果需要让下拉区域始终为全屏，可以给 PullRefresh 设置一个与屏幕大小相等的最小高度：

vant van-icon使用自定义图标

iconfont图标库： https://www.iconfont.cn/

搜索自己喜好的图标 添加入库

点击我的图标库 选择对应的项目 点击确定

点击更新代码

复制css代码到 Vue项目中

引入到项目中的位置 切记打包时 要配置http或https的形式

可以在App.vue 或main.js 我这里是配置在main.js中

vue文件中的使用

<template>
  <div id="tabbar">
    <!-- 给tabbar route属性  然后给每一项to属性就可以路由跳转了 -->
    <van-tabbar  route>
      <van-tabbar-item icon="home-o" to="/">书架</van-tabbar-item>
      <van-tabbar-item to="/bookShop" >
        <div class="customTabbarItem">
          <!--引入自定义图标-->
          <van-icon class="iconfont iconicon_huabanfuben icon_margin"/>
          <span>书城</span>
        </div>
      </van-tabbar-item>
      <van-tabbar-item to="/bookClass" >
        <div class="customTabbarItem">
          <!--引入自定义图标-->
          <van-icon class="iconfont iconleimupinleifenleileibie icon_margin"/>
          <span>分类</span>
        </div>
      </van-tabbar-item>
      <van-tabbar-item icon="user-o" to="/profile">我的</van-tabbar-item>
    </van-tabbar>
  </div>
</template>
