replyThis should be a bug in the framework. I can't see the code for your left menu now, and I don't know the specific situation.
You can use the js method on the left menu. After clicking, execute the event and change the src value of the iframe. That's it.
replyTeacher, the value of src can be accessed separately. The only situation that cannot be solved is that the iframe page will keep loading. I dare not change the files in the H UI and keep them as they are. I looked for the files in JS if(!bStop){
creatIframe(href,title);
min_titleList();
}
else{
show_navLi.removeClass("active").eq(bStopIndex).addClass("active");
iframe_box.find(".show_iframe").hide().eq(bStopIndex).show().find("iframe").attr("src",href);
}
Didn't see the corresponding event
