jquery sortable serialize returns empty string
html, jquery, jquery-ui-sortable
Solution
The id attributes on your li's need to look like this:
<ul id="categories_list" class="ui-sortable">
<li class="catRow_1" style=""> item1 </li>
<li class="catRow_2" style=""> item2 </li>
<li class="catRow_3"> item3 </li>
</ul>
You need to have the order number seperated by an underscore as per here.
Problem
HTML: ``` <ul id="categories_list" class="ui-sortable"> <li class="cat_row" style=""> item1 </li> <li class="cat_row" style=""> item2 </li> <li class="cat_row"> item3 </li> </ul> ``` Javascript: ``` $("#categories_list").sortable({ placeholder: 'sortable_placeholder', update : function () { var order = $("#categories_list").sortable('serialize'); console.log(order); } }); ``` order returns "empty string" why is that?
