textarea根据内容自动增加高度

<textarea v-model="cureInfo.Symptom" id="symptomTxt" oninput="autoTextAreaHeight(this)" ></textarea>

js处理:

    function autoTextAreaHeight(o) {        o.style.height = o.scrollTop + o.scrollHeight + "px";    }    $(function () {        var ele = document.getElementById("symptomTxt");        autoTextAreaHeight(ele);    })
