使用js 设置组合快捷键
使用js设置快捷键的本质就是获得你要设置的这个键的keyCode 的值，如果要加ctrl，alt，shift，那么就添加一个ctrlkey，altKey，shiftKey来判断下，所以关键在于获取keycode的值。
(1) 设置 ctrl +enter 提交
1 if (e.ctrlKey && e.keyCode == 13){
2 return submit();
3 }
(2) 设置 Alt+ 方向键 ←提交
1 if (e.altKey&& e.keyCode == 37){
2 return submit();
3 }
(3) 设置 shift+F10 提交
1 if (e.shiftKey&& e.keyCode == 37){
2 return submit();
3
4 }
(4) 设置enter 提交
1 if (e.keyCode == 13){
2 return submit();
3 }

{
alert("你按了键盘ENTER.");
}
});
</script>
