vue.js - vuejs 搜索过滤器“TypeError：无法读取 null 的属性‘过滤器’”

问题描述

我想按表中的 tc 编号搜索。我利用了https://element.eleme.io/#/en-US/component/table。但我收到如下错误。

“TypeError：无法读取 null 的属性‘过滤器’”

我写的代码如下。

<template>
 <div class="app-container">
  <div class="filter-container">
   <el-input :placeholder="TC arama" v-model="search" style="width: 
     200px;" class="filter-item"/>
  </div>
  <el-table
   :data="list.filter(data => !search || 
    data.tc.toLowerCase().includes(search.toLowerCase()))"
   border
   fit
   highlight-current-row
   style="width: 100%;">
   <el-table-column :label="ID" prop="id" width="65"/>
   <el-table-column :label="TC" prop="tc" min-width="110px"/>
 </el-table>
</div>
</template>

<script>
export default {
    data() {
        return {
            filter: '',
            search: '',
            list: [{
                id: 1,
                tc: "12345678944"
            }, {
                id: 2,
                tc: "25639874532"
            }, {
                id: 3,
                tc: "23669874120"
            }]
        }
    }
}
</script>
