listbox return wrong value in wordpress3.9
问题 I used the listbox UI element in Wordpress 3.8, but it does not work in its newer version (3.9). I wrote this JS code to test it: (function() { var ICONS; var icon = function(id) { return '<i class="fa fa-' + id + '"></i>'; } ICONS = ["rub", "ruble", "rouble", "pagelines", "stack-exchange", "arrow-circle-o-right", "arrow-circle-o-left", "caret-square-o-left", "toggle-left", "dot-circle-o", "wheelchair", "vimeo-square", "try", "adjust", "anchor", "archive", "arrows", "arrows-h", "arrows-v",
