The example in this article describes the method of jQuery controlling frames and frame page JS. Share it with everyone for your reference, the details are as follows:

<script src="jquery-1.3.2.min.js" type="text/javascript" ></script>
<script>
var _intervalx,steplengthx
steplengthx=1000; //第一次触发时间
nextstepx=10000 ; //以后的触发时间
$(document).ready(function(){
 _intervalx=setInterval("CheckUser()",steplengthx);
});
function CheckUser() //发送查找程序
{
  if(parent.frames["frmMain"].location.pathname!="/SysMan/user_agent.asp") //如果是在user_agent.asp页面下就不提示
  {
   $.post("../webchat/chat.asp",{"action":"checkuser"},function(data)//初始化留言
   {
    if(parseInt(data)>0) //
    {
      if($(window.parent.frames["frmMain"].document).find("#message").length<1) //如果页面已经添加就不再添加
      {
      var messages="<div id=message><ul><li>有新客户发出客服申请</li><li><a href=../SysMan/user_agent.asp target=_self>在线客服</a></li></ul></div>"
      }
      $(window.parent.frames["frmMain"].document).find("body").append(messages)
      $(window.parent.frames["frmMain"].document).find("#message").show();
      TimeOut();
    }
   });
   clearInterval(_intervalx);
   _intervalx=setInterval("CheckUser()",nextstepx);
  }
}
function TimeOut()
{
  setTimeout(function(){$(window.parent.frames["frmMain"].document).find("#message").hide("slow");},5000) //3秒关闭
}
</script>
