javascript - .next() jquery function skips next sibling -

-

i trying remove class element , add class next element. problem next element gets skipped. here javascript:

var $active = this.$view.find('.active'); if ($active.index() !== this.$view.children().length - 1) {     $active.next('.list-group-item').addclass('active');     $active.removeclass('active'); }

here html:

 <div>      <a class="list-group-item active">1</a>      <a class="list-group-item active">2</a>      <a class="list-group-item active">3</a>      <a class="list-group-item active">4</a>  </div> 

$('.list-group-item').on('click',function(){      debugger;      var $active = $(this).parent().find('.active');      if ($active.index() !== $(this).parent().children().length - 1) {          $active.next('.list-group-item').addclass('active');          $active.removeclass('active');      }  });
.active{      font-weight:bolder;  }
<div>       <a class="list-group-item active">1</a>       <a class="list-group-item ">2</a>       <a class="list-group-item ">3</a>       <a class="list-group-item ">4</a>  </div>

points first

  • .active class given tags.
  • then after finding tag's children element never coz it's not having.

i have corrected desired code way change prospective work

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
