【微信小程序】在 wxml 文件中不能使用 Array.includes 方法问题

gengboxb 2022-04-28 275 0

wxs 中写一个方法

<wxs module="tools">
  var includes = function (array, searchElement) {
    return array.indexOf(searchElement) !== -1
  }
  module.exports = {
    includes:includes
  }
</wxs>

使用：

<view class="btn_wrap" wx:if="{{tools.includes(item.containType,type)}}">
    <view>test</view>
</view>
