功能键F2的键控代码 [英] keycode for function key F2

问题描述

大家好，

在F2中，按下文本框按键事件，我需要显示一个弹出窗口.即使我使用F2的键码为113，也无法正常工作.我在javascript中将此ketpress事件编写为

if(window.event&& window.event.keyCode == 113)
{
popup.show();
}

但这是行不通的.可以问一个理由或为F2提供合适的代码吗?

Hi every one,

{
popup.show();
}

but this is not working. can any one sujjest the reason or provide the suitable code for F2 press

推荐答案

您可以使用jQuery捕获按键事件.

jQuery .keypress() [

You can use jQuery to trap the keypress events.

jQuery .keypress()[^] - View the demo provided on this page.

Swathi，

试试这个

Hi Swat

Try this

<script language="javascript">
document.onkeyup = KeyCheck;

function KeyCheck(e)
{
   var KeyID = (window.event) ? event.keyCode : e.keyCode;
   if(KeyID == 113)
   {
      alert("hi");
   }
}
</script>

document.onkeydown =函数Open(event){

if(window.event && window.event.keyCode == 113)
{
document.getElementById(''ctl00_ContentPlaceHolder1_ImageButton5'').click();
}
否则if(event.which == 113)
{
document.getElementById(''ctl00_ContentPlaceHolder1_ImageButton5'').click();

}


}

document.onkeydown = function Open(event){

if(window.event && window.event.keyCode == 113)
{
document.getElementById(''ctl00_ContentPlaceHolder1_ImageButton5'').click();
}
else if(event.which == 113)
{
document.getElementById(''ctl00_ContentPlaceHolder1_ImageButton5'').click();

}


}
