Wrap every 3 divs in a div

Question

Is it possible to use nth-child selectors to wrap 3 divs using .wrapAll? I can\'t seem to work out the correct equation.

so...

Answer 1

I've written a generic chunk function that makes this quite easy to do:

$.fn.chunk = function(size) {
    var arr = [];
    for (var i = 0; i < this.length; i += size) {
        arr.push(this.slice(i, i + size));
    }
    return this.pushStack(arr, "chunk", size);
}

$("div > div").chunk(3).wrap('
');

$.fn.chunk = function(size) {
  var arr = [];
  for (var i = 0; i < this.length; i += size) {
    arr.push(this.slice(i, i + size));
  }
  return this.pushStack(arr, "chunk", size);
}

$("div > div").chunk(3).wrap('
');

div > div {
  width: 50px;
  height: 50px;
  background: blue;
  margin: 2px;
  float: left;
}

div.new {
  background: red;
  height: auto;
  width: auto;
  overflow: auto;
}
