Detailed explanation of toggle replacement method in jQuery

This article mainly introduces the relevant information of jQuery toggle alternative method. Friends who need it can refer to it

The specific content is as follows:

$('.back_left dt').toggle(function(){
$(this).addClass("selected");
$(this).siblings('dd').slideUp();
},function(){
$(this).removeClass("selected");
$(this).siblings('dd').slideDown();
});

Today in When I was working on a project, I copied a code from someone else's website and found that it couldn't be implemented. When I was so anxious that I didn't want to do it anymore, I thought, could it be a jquery version problem? Then I lowered the jquery version to 1.8 and the function was implemented. My own jqurey version is 1.11.1. It turned out to be a version problem. Once I found the reason, it was easy to solve. After searching on Baidu, I found that the toggle method was in version 1.9. It has beendeleted. Changing the version can solve the problem, but I don't want to use the lower version anymore. I still want to use the 1.11.1 version. What method can I use to replace toggle?

After testing, you can use the following method instead:

$(document).ready(function(){ 
$('.back_left dt').click(function(){
if($(this).hasClass("selected")){
$(this).toggleClass("selected");
$(this).siblings('dd').slideDown();
}else{
$(this).toggleClass("selected");
$(this).siblings('dd').slideUp();
} 
}); 
});
