在加载WEB页面时，是否可以自动创建从键盘按键的效果？

<script type="text/javascript">
$(document).keypress(function(event){
var key = (event.keyCode ? event.keyCode : event.which);
var ch=String.fromCharCode(key);
alert('You pressed key : ' +ch);
$("inputSelector").trigger($.Event("keypress", { keyCode: 90 }));
});
</script>

您需要一个EventListener。
试试这个：
document.addEventListener('keypress', logKey);
function logKey(e) {
alert( `You pressed key: ${e.code}`);
}
