我的 aspx 页面中有标签，目前我已将其设计为在 onclick 事件上加载。我正在尝试加载按键事件。按键事件未触发，如果我尝试向下/向上箭头，则选项卡正在导航。任何人都可以请帮忙。

    $(function () {

    });       
   $(document).ready(function () {
       if ('<%=Session["ProjectID"]%>' != "") {
           $('#Contacts').attr('href', '#ContactsPage');
           $('#Comments').attr('href', '#CommentsPage');
           $('#RiskSummary').attr('href', '#RiskAssessmentSummaryPage');

尝试使用 onfocus而不是onkeypress

像这样

<li><a id="Contacts"  href="#iframeInitiative" onclick="return loadIframe( 'ifrm', 'Contacts.aspx')" onfocus="return loadIframe( 'ifrm', 'Contacts.aspx')">Contacts</a></li>

添加此代码

代码

  $(function(){
    $('a:first').focus
    var id=$('a:first').focus();
});
$(document).on('keydown',function(e)
   {
       if(e.which==40)
       {
          id=$("*:focus");
          id.parents('li').next().find('a').focus();
       }
       else if(e.which==38)
       {
           id=$("*:focus");
           id.parents('li').prev().find('a').focus();

       }
 });
