就在我添加数据，改变路由的时候，报错了

代码：

<template>

<div>

<p>标题</p>

<input type="text" v-model="title">

<p>内容</p>

<input type="text" v-model="content">

<div class="btn" @click="add()">添加</div>

</div>

</template>

<script>

import store from '@/store'

export default {

name: 'Add',

data () {

return {

title: '',

content: ''

}

},

methods: {

add() {

store.commit('addItem', {

title: this.title,

content: this.content

})

this.title = ''

this.content = ''

this.$router.push('/home/list')

}

}

}

</script>

<style scoped>

</style>
