                    </form>
        </div><!-- End Search Menu -->

我需要关注输入 id="ara"当点击 id="arabutton"

我怎样才能做到这一点？它是一个实时搜索系统。当单击按钮时，会出现类型覆盖输入字段。

您应该使用 JavaScript:

document.addEventListener('DOMContentLoaded', () => {
  const input = document.getElementById('ara');
  const button = document.getElementById('arabutton');

  button.addEventListener('click', () => {
    input.focus();
  })
})
