vue中，本页面中如何获取products的数据？

Question

问题遇到的现象和发生背景

想直接从页面获取products里面的数据，但是系统一直报products is not defined

问题相关代码，请勿粘贴截图

<template>
  <div class="search">
    <input type="text" placeholder="输入搜索内容" v-model="searchContent">
    <button type="button" @click="search">搜素</button>
    <ul v-for="(booklist) in book">
      <li>{{ booklist }}</li>
    </ul>
  </div>
</template>

<script>
export default {
  name:"search",
  data(){
    return{
      searchContent:"",
      booklist:[],
      book:[],
    products:[
      {name:"世界地图册",price:"$45",number:1001},
      {name:"古埃及历史",price:"$40",number:1002},
      {name:"一千零一夜",price:"$55",number:1003},
      {name:"李清照词传",price:"$25",number:1004},
      {name:"日俄战争纪实",price:"$35",number:1005},
      {name:"白夜",price:"$30",number:1006},
    ],
    }
  },
  methods:{
    search(){
      if(this.searchContent){
        if(!isNaN(parseInt(this.searchContent))){
          for(i in products){
            if(products[i].number == parseInt(this.searchContent)){
              this["book"].push(this.products[i]);
            };
          };
        } else {
          for(i in products){
            if(products[i].name.indexOf(this.searchContent) >= 0){
              this["book"].push(products[i]);
            };
          };
        };
      }else{
        alert("请正确输入筛选条件！")
      };
    }
  },
}
</script>

运行结果及报错内容

我的解答思路和尝试过的方法

上网各种搜索，都不符合这样的情况

我想要达到的结果

输入number或者name实现搜索功能

请教一下大家，如何修改代码，才能实现效果？

你没有写this.

<script>
export default {
  name:"search",
  data(){
    return{
      searchContent:"",
      booklist:[],
      book:[],
    products:[
      {name:"世界地图册",price:"$45",number:1001},
      {name:"古埃及历史",price:"$40",number:1002},
      {name:"一千零一夜",price:"$55",number:1003},
      {name:"李清照词传",price:"$25",number:1004},
      {name:"日俄战争纪实",price:"$35",number:1005},
      {name:"白夜",price:"$30",number:1006},
    ],
    }
  },
  methods:{
    search(){
      if(this.searchContent){
        if(!isNaN(parseInt(this.searchContent))){
          for(i in this.products){
            if(this.products[i].number == parseInt(this.searchContent)){
              this["book"].push(this.products[i]);
            };
          };
        } else {
          for(i in this.products){
            if(this.products[i].name.indexOf(this.searchContent) >= 0){
              this["book"].push(this.products[i]);
            };
          };
        };
      }else{
        alert("请正确输入筛选条件！")
      };
    }
  },
}
</script>
