Using next() x number of times with jQuery
What's an easy way to iterate x number of times using next()
(applying the same function each time)?
I am working in Sharepoint and have limited control of the HTML; what I can do is find an element by its ID, track down the closest <td>
, hide()
it, and then move on to the next one (I don't want all the <td>
's, just about 7 or 8 in a row).
The code below works but it's not that pretty.
$("#my-easily-identifiable-id").closest("td").hide();
$("#my-easily-identifiable-id").closest("td").next().hide();
$("#my-easily-identifiable-id").closest("td").next().next().hide();
$("#my-easily-identifiable-id").closest("td").next().next().next().hide();
[ ... etc ... ]
What's a better way to do this?

PS: added a fiddle (genius)
Use .nextAll()
+ .andSelf()
with .slice()
.
$("#my-easily-identifiable-id").closest("td").nextAll().andSelf().slice(0, 7);
I think a simpler solution than those posted so far would be .nextUntil()
:
//to get next 8 elements
var i = $('#my-easily-identifiable-id').index();
$('#my-easily-identifiable-id').closest('td').nextUntil('', ':lt(' + (i+8) + ')');
//to get self and next 3
var i = $('#my-easily-identifiable-id').index();
$('#my-easily-identifiable-id').closest('td').nextUntil('', ':lt(' + (i+3) + ')').andSelf();
Grabs all "next" elements until the filter is hit (in this case we choose the next 8 elements). Verified by jsFiddle.
I've not tried it, but perhaps the following might work (I'll test momentarily):
$("#my-easily-identifiable-id").siblings().slice($(this).index(),($(this).index() + 8)).hide();
Tested and verified with a JS Fiddle demo.
Maybe something like this:
$("#my-easily-identifiable-id").closest("td").hide();
$("#my-easily-identifiable-id").closest("td").nextAll().hide();
