Find the next element that is not immediate?

问题:

I want to find the first span element after class counter, in code something like this:

<div class="counter"></div>
<p></p>
<span></span>

It seems like the next() function only finds the immediate next element, so something like this:

$(".counter").next("span")

Won't work. The way I have been using is a bit lengthy and I was wondering if there was a shorter way, it is this:

$(".counter").nextAll("span").eq(0)

I think the closest() method in jQuery 3 will do the trick, but I am using 1.2.6 -- is there a better way to do this (am I just using next() wrong?)

回答1:

I think your method is the best way. And if you feel it doesn't look good just turn it into a plugin:

jQuery.fn.firstAfter = function(filter){
 return this.nextAll(filter).eq(0);
}

回答2:

Similar to the marked answer but looks a little cleaner using the :first selector:

$('.counter').nextAll('span:first')

回答3:

I think the siblings() function is what you are looking for. Try something like this:

$(".counter").siblings("span");

I'm not sure that the closest method will do the trick, but if so... maybe you can extract the closest method from 1.3 and turning it into a plugin?

I haven't had a chance to try this, but give it a shot. It can't hurt:

(function($) {
  $.fn.closest = function (selector) {
    return this.map(function(){
      var cur = this;
      while ( cur && cur.ownerDocument ) {
        if ( $(cur).is(selector) )
          return cur;
        cur = cur.parentNode;
      }
    });
  }
})(jQuery);

Try something like this:

$(".counter ~ span:first");

Hope that helps!

$(".counter + span")
