const replayInputRef = useRef(null)
<textarea
className={styles['com-btm-reply-text']}
id='re_input'
ref={replayInputRef}
onKeyDown={replayInputText}
placeholder="Enter发送,Shift+Enter换行"

autoFocus={true} >
</textarea>
// @ts-ignore
const replayInputText = (e) => {
const replayInputRefCurrent = replayInputRef.current as unknown as HTMLDivElement as any
const replayText = replayInputRefCurrent.value//获取输入的值
// enter回车键判断和shit+enter的判断,因为默认enter有enter+shif的换行功能
if (!e.shiftKey && e.keyCode === 13) {
e.cancelBubble = true; //ie阻止冒泡行为
e.stopPropagation();//Firefox阻止冒泡行为
e.preventDefault(); //取消事件的默认动作*换行
setOnEnter('onEnter')//按下回车键onEnter为true
replayInputRefCurrent.value = ''//Enter之后情况输入的文本
// 将输入的内容push到指定显示内容的位置
setList([
...list,
id: list.length + 1,
useId: 'User_10',
time: '2022-10-10 08:00:00',
solve: 'solved',
content: replayText
tsx中,如果不使用any的,就用这第二种方式
// @ts-ignore
const replayInputText = (e) => {
let replayInputRefCurrent = (document.getElementById('re_input') as HTMLInputElement).value; //获取输入的值
// enter回车键判断和shit+enter的判断,因为默认enter有enter+shif的换行功能
if (!e.shiftKey && e.keyCode === 13) {
e.cancelBubble = true; //ie阻止冒泡行为
e.stopPropagation();//Firefox阻止冒泡行为
e.preventDefault(); //取消事件的默认动作*换行
setOnEnter('onEnter');//按下回车键onEnter为true
(document.getElementById('re_input') as HTMLInputElement).value = ''
setList([
...list,
id: list.length + 1,
useId: 'User_10',
time: '2022-10-10 08:00:00',
solve: 'solved',
content: replayInputRefCurrent
在TSX中的用法
const replayInputText = (e: React.KeyboardEvent) => {
const replayInputRefCurrent = (document.getElementById('re_input') as HTMLInputElement).value
// enter回车键
if (!e.shiftKey && e.key === 'Enter') {
// e.cancelBubble = true //ie阻止冒泡行为,React.KeyboardEvent不支持
e.stopPropagation() //Firefox阻止冒泡行为
e.preventDefault() //取消事件的默认动作*换行
setOnEnter('onEnter') //按下回车键onEnter为true
; (document.getElementById('re_input') as HTMLInputElement).value = '' //Enter发送成功后清空value
setList([
...list,
id: list.length + 1,
useId: 'User_10',
time: '2022-10-10 08:00:00',
solve: 'solved',
content: replayInputRefCurrent
