New sorting method with Jade & Flexbox

index.html

//The slice, sort, and for loop are not necessary.  However, they are there for your conveinence when adding new price keys.  If you want to drop those things, then you would have to add and change a new "order" key & value each time you add a new price key & value.  For example, in this demo, $245 is the highest price.  You would want a priceAry.order value of 0 for it (or the corresponding CSS order property value).  You can see how manual changes can become unmaintainable.  I wanted to handle this side of things in the template and not on the client side JS.
- var priceAry = [{"price":"25"},{"price":"245"},{"price":"15"},{"price":"55"},{"price":"50"},{"price":"35"},{"price":"75"},{"price":"150"},{"price":"175"},{"price":"55"},{"price":"125"},{"price":"100"}]
- var newAry = priceAry.slice(0);
- priceAry.sort(function(a, b){
 - return b.price-a.price
- })
- for (var i = 0; i < priceAry.length; i++) {
  - priceAry[i].order = i
- }
.button-wrapper
  button#default Arrange by relevance (default)
  button#high-to-low Arrange highest to lowest
  button#low-to-high Arrange lowest to highest
ul#grid
  each val, index in newAry
    li(class="sortable", data-order=val.order, data-default=index)
      i.fa.fa-picture-o.fake-image
      span.price= "$" + val.price

New sorting method with Jade & Flexbox

Generally, sorting is pretty easy. So is there a way to make it even easier? We can take advantage of CSS order to sort by 3 options. Here's the kicker: we don't need to use an array or object sort, and we don't need to use .append(). Most of the work is done in the Jade template. To watch it adapt to new data, add a new "price" key in the priceAry variable.

document.getElementById("high-to-low").addEventListener("click",function(){
  sortItems("order");
});
/*You are probably thinking to yourself, hey why not use row-reverse on the grid id?  I tried that originally, but is was only reversing individual rows.  If you wanted multiple rows then you were out of luck.  This works even better.*/

  sortItems("order","-");

  sortable[sortable.length-1].addEventListener("transitionend", function(){
    for (var i = 0; i < sortable.length; i++) {
    //Get the element by data-order and change the order style.  That's all you have to do!  You could probably substitute data-order for an id, but the data attribute seemed more logical
    var dataSelect = document.querySelector("[data-" + dataType + "='" + i + "']")
    dataSelect.style.order = neg + i;
      dataSelect.style.opacity = 1;
      dataSelect.style.transitionDelay = (delay -= 0.02) + "s";
