I want to clear the input after clicking submit button, how do I do it?

<div class="reply">
        <div class="reply_to">
          <p style="float: left"><span style="color: gray">Reply To :</span> User Report Name</p>
        </div>
        <div contenteditable="true" ref="replyingReport" class="reply_report"></div>
        <div @click="submit" class="reply_send"><b>Send</b></div>
</div>

above is the code I have, and I want to clear the div with class “reply_report”
