如何将JSON数组{{this.row}}传递给commit（）函数，以使用Axios.post进行发布

Question

this.row正在将表单输入生成到JSON数组中，我正尝试使用Axios通过Submit函数将其发布，但无法提供该值，请帮助出什么问题？

Axios邮政编码

axios.post('/submit', this.rows).then(response => {
                        this.rows; //Clear input fields.
                        this.loaded = true;

这是我的完整代码

    <template>
    <form @submit.prevent="submit">
        {{ /* These are 3 buttons which are calling 3 different function to create input boxes  */ }}
        <div class="d-flex mt-5"><div>
            <label>Add A</label>
            <button type="button"  @click="addRow">01</button>
        </div>
            <div> <label>Add B</label>
                <button type="button"  @click="addRow1">02</button>
            </div>
            <div> <label>Add c</label>
                <button type="button"  @click="addRow3">03</button>
            </div>
        </div>
{{ /* this section calls button-counter template from script code  */ }}
        <div v-for="row in rows" :key="row.id">
            <button-counter :name ="row.name" :id="row.id" :value.sync="row.value"></button-counter>
        </div>

        <div>
            <button type="submit" class="btn btn-primary">Add Points</button>

        </div>


        <div v-if="success" class="alert alert-success mt-3">
            Message sent!
        </div>
    </form>
</template>

        },
/* This is my template which gets called fro the addition of new inputs ...guess here I need to add v-model so that dynamically generated fields will be posted but I'm unable to get it posted */

您可以使用JSON.stringify(array_to_convert_in_string_to_send_in_ajax)，但您还必须在后端服务器中对其进行json_decode解码

例如在服务器部分中的laravel：

$result = json_decode($request->your_array);
