vue中@input的时候在InputEvent中传递额外的参数

        <div
          class="edit-text-area"
          contentEditable="true"
          @input="
            e => {
              templateValueChange(e, item);
            }
          "
          data-schema-template-id="1"
          style="width: calc(100% - 2em);"
          v-html="item.value"
        >
        </div>
