jQuery->如何找到具有特定ID的div，然后添加class（'activeFeaturedNews'）;

Question

$('.btnReadMore').click(function(){
   var tempId = $(this).attr('id');
   $('div#'+tempId).addClass('activeFeaturedNews');
});

From the first page, When I click on an anchor tag it will pass its Id to the next page then find the div with the same id then add class.

Answer 1

On click of the anchor tag you can keep the id in the localStorage and on next page use getItem interface to get the stored element

$('.btnReadMore').click(function(){
   localStorage.setTime("tempId",$(this).attr('id');
})

On next page

var getItemId = localStorage.getItem("tempId");
$("body").$('div#'+tempId).addClass('activeFeaturedNews');

Answer 2

The problem is without redirecting it to the next page how come you can addClass? During the click function, first redirect it to the second page. Then addClass as you did.

Answer 3

You can simply pass the id as hash parameter in href eg href="http://example.com/about#your-id"

Now, on next page, you can get the hash using javascript ie

var curHash = window.location.hash;
$(""+curHash).addClass('activeFeaturedNews');
