Utilizing Vue to bind data for asynchronous Axios requests

Having an issue with my Vue function that is triggered by a button click. It makes an axios call, but the problem is that no matter what I type in the textarea (v-model taskCommentBody), it sends the data commentBody as blank. Not sure what's causing this issue.

Any insights on what could be going wrong here?

<div class="form-group row">
                <textarea v-model="taskCommentBody" class="form-control col" rows="6" placeholder="What are your thoughts on this task?" name="task-comment"></textarea>
</div>
<button v-on:click="saveTaskComment" role="button" class="btn btn-primary" type="submit">
                Save Comment
</button>

 /**/
saveTaskComment() {
            axios.post('/task/comment/save', {
                    commentBody: this.taskCommentBody
                })
                .then((response) => {
                    // handle success
                    this.comments.unshift(response.data.content);
                })
                .catch(function (error) {
                    // handle error
                })
                .finally(() => {
                    this.$root.taskCommentBody = '';
                });
        }

Answer №1

Although I sense there may be a solution already out there for this issue, I haven't been able to find it. So, here's my take on providing a definitive answer...

It is crucial that any value you wish to be responsive in a Vue component or instance is explicitly defined within the data property. Failure to do so will prevent Vue from generating the necessary observable properties required for reading and writing values with v-model bindings.

Therefore, in your scenario, you should have something like

data: () => ({
  comments: [],
  taskCommentBody: ''
})

If someone can identify an existing post, I am open to marking this as a duplicate and transforming this answer into a community wiki.
