使用js 设置组合快捷键
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 }

<script type="text/javascript">
//当onkeydown 事件发生时调用hotkey函数
$("#CarNo").keydown(function (e) {
if (e.keyCode == 13)
{
alert("你按了键盘ENTER.");
}
});
</script>
