请问各位大佬如何替换原网页中的按键监听事件
```$(document).keydown(function (event) {//alert(event.keyCode);
switch (event.keyCode) {
case 13: //Enter
if (chooseNo == "saleorder.sourceid") {
$("input").focus();
return false;
}
if (chooseNo == "saleorder.remark") {
$("input").blur();
beginAddDetail();
}
if (chooseNo == "unitnum") {
$("input").focus();
return false;
}
if (chooseNo == "auxnum") {
$("input").focus();
return false;
}
if (chooseNo == "overnum") {
if ($("input").attr("readonly") == "readonly") {
$("input").focus();
}
else {
$("input").focus();
}
return false;
}
if (chooseNo == "taxprice") {
$("input").focus();
return false;
}
if (chooseNo == "boxprice") {
$("input").focus();
return false;
}
if (chooseNo == "remark") {
$("input").click();
return false;
}
break;
case 27: //Esc
$("#sales-remark-swapOrderDetailAddPage").focus();
$("#sales-dialog-swapOrderAddPage-content").dialog('close');
break;
//case 37: //←
// $("#button-back").click();
//break;
//case 39: //→
// $("#button-next").click();
//break;
case 38://↑
var detaildialog = $("#sales-dialog-swapOrderAddPage-content").length;
if(detaildialog == 0 ){
var row = $wareList.datagrid('getSelected');//console.log(row);
var selectindex = $wareList.datagrid('getRowIndex', row);
if(selectindex == -1){
selectindex = 0;
}else{
$wareList.datagrid('unselectRow',selectindex);
-- selectindex;
}
$wareList.datagrid('selectRow',selectindex);
var selectRow =$wareList.datagrid('getRows');
var customerid = $("#sales-customer-hidden-swapOrderAddPage").val();
if (priceFloat > 0 && selectindex > -1) {
showPirceMenu(selectindex,customerid, selectRow.goodsid);
}else{
$("#sales-goodsPriceMenu-orderPage").menu('hide');
}
}
break;
case 40://↓
var detaildialog = $("#sales-dialog-swapOrderAddPage-content").length;
if(detaildialog == 0 ){
var row = $wareList.datagrid('getSelected');//console.log(row);
var selectindex = $wareList.datagrid('getRowIndex', row);
if(selectindex == -1){
selectindex = 0;
}else{
$wareList.datagrid('unselectRow',selectindex);
++ selectindex;
}
$wareList.datagrid('selectRow',selectindex);
var selectRow =$wareList.datagrid('getRows');
var customerid = $("#sales-customer-hidden-swapOrderAddPage").val();
if (priceFloat > 0&& selectRow != undefined && selectRow.goodsid != undefined) {
showPirceMenu(selectindex,customerid, selectRow.goodsid);
}else{
$("#sales-goodsPriceMenu-orderPage").menu('hide');
}
}
break;
case 65: //a
if (event.altKey) {
$("#button-add").click();
}
break;
case 83: //s
if (event.ctrlKey) {
$("#button-save").click();
return false;
}
break;
}
});
```
以上是原代码，主要想改原网页里按回车input获得焦点的顺序，我用removeEventListener不成功。 ```
window.addEventListener("keydown", (event) => {
const e = window.event || event
const k = e.keyCode || e.which
event.stopPropagation()
if (e.ctrlKey || e.shiftKey || e.altKey || e.metaKey) return
switch (k) {
case 32:
alert("success!")
break
}
}, true)
``` 虽不算完美，也谢谢大佬解答
