问题描述

我需要将所有数据属性从选项标签传输到UI选择菜单项（li标签）。这怎么用API？

I need to transfer all data-attributes from option tags to to UI selectmenu items (li tags). How do this with API ?

<select class="select" id="" name="PROPERTY[126]">
  <option value="315" data-filter="flat">Квартира</option>
  <option value="316" data-show="standart" data-filter="room">Комната</option>
  <option value="317" data-filter="house" data-hide="standart flat room uchastok" data-show="house zarub elite">Коттедж</option>
  <option value="318" data-filter="uchastok" data-show="zarub uchastok elite" data-hide="standart flat room house">Участок</option>
  <option value="319" data-filter="zarub" data-show="elite" data-hide="standart">Зарубежная недвижимость</option>
</select>

<script>$("select").selectmenu()</script>

推荐答案

将此添加到您的代码中，数据属性将复制：

add this to your code and data attributes will copy:

$.widget( "ui.selectmenu", $.ui.selectmenu, {
   _renderItem: function( ul, item ) {
        elementdata = item.element.context.dataset;
        attributesObj = {};
        Object.keys(elementdata).forEach(function(x){
            attributesObj["data-"+x] = elementdata[x]; 
        });
        return $( '<li>' )
         .attr(attributesObj)
            .append(item.label)
            .appendTo( ul );
   } 
});
