引导导航栏活动状态

Question

• I have a website with a common heading.
• That heading is included a navigation bar.
• When I click a navigation item in the bar page load happens.
• Considering the context how can I set the Bootstrap navigation bar active state for navigation item which is related to the loaded page.

Since there is a page load when clicking on a navigation bar item, I cannot just use

 $(".nav a").on("click", function(){ $(".nav").find(".active").removeClass("active"); $(this).parent().addClass("active"); }); 

Please provide me a better solution.

Answer 1

When the page is loaded you have to check if the links of the anchors match with the page location.

$(".nav a").each(function() {
  if(document.location.href.indexOf(this.href)>=0) {
      $(this).parent().addClass("active");
    }
});

Answer 2

As a solution for my issue, I followed the following way.

I added HTML IDs for each of my navigation bar items. Then in each page related to each navigation bar item, I added Bootstrap active class using javascript as follows.

$("#ID_of_the_navi_bar_item").addClass('active');
