This time I will bring you the navigation effect of using .active dynamically. What are the precautions for using .active dynamically to achieve navigation effect? The following is a practical case. Let’s take a look.

Get the link to the page you open through jq window.location.pathname;

Add an ID to your li in HTML. The naming of the id is the same as the href in the URL link

Find the corresponding li through the jq include method and add the active class name to it

Then. . There's no after that. . .

jq code:

$(function() {
 varli = $(".title_ul").children("li");
 for(vari = 0; i < li.length; i++) {
 varurl = window.location.pathname;
 varurl = url.replace("/","");
 if(url.indexOf(li[i].id)!=-1) {
  li[i].firstChild.className ="active";
 
 }else{
  li[i].firstChild.className ="";
 }
 }
})
