我想在Vue中使用“includes”来处理我的v-model和Vue.js日志错误，但是如果我写（.includes（“blabla））->就好了。
问题是什么？
如何返回所有数组if（if）？
像这样.emojiesByCategory.push（）？
请帮帮忙

<template>
    <div id="app">
        <div class="emoji_picker">
            <div class="picker_container">
                <input v-model="search">
                <div class="category"
                     v-for="category in categories"
                     :key="`category_${category}`"
                >
                    <span>{{ category }}</span>
                    <div class="emojis_container">
                        <button
                            v-for="(emoji, index) in category_emojis(category)" // ERROR HERE
                            :key="`emoji_${index}`"
                        >
                            {{ emoji }}
                        </button>
                    </div>
                </div>

        </div>
    </div>
</template>

        return {
            search: "",
            emojiesByCategory: ""
        }
    },
    computed: {
        categories() {
            return Object.keys(data);
        },

        category_emojis: () => (category) => {
            for (let i = 0; i < Object.keys(data[category]).length; i++) {
                if (Object.keys(data[category])[i].includes(this.search)) { // ERROR THERE !!!
                    console.log(Object.values(data[category])[i]) 
            }
            return Object.values(data[category])
        }
    },
}
</script>
