Question

假设我有这个选择：

<select class="required form-control parameter-criteria" selectpicker="" data-id="2" tabindex="-98">
    <optgroup label="criterio 2">
        <option value="1" data-content="<span class=&quot;badge-min filter d-inline-flex&quot; style=&quot;background-color:#ff0000;&quot;> </span>CRITERIO 1 [0 - 50] - CRITERIO 2" id-criteria="2">CRITERIO 1
        </option>
       <option value="2" data-content="<span class=&quot;badge-min filter d-inline-flex&quot; style=&quot;background-color:#ffb700;&quot;> </span>CRITERIO 2 [51 - 60] - CRITERIO 2" id-criteria="2">CRITERIO 2
       </option>
       <option value="3" data-content="<span class=&quot;badge-min filter d-inline-flex&quot; style=&quot;background-color:#66ff00;&quot;> </span>CRITERIO 3 [61 - 100] - CRITERIO 2" id-criteria="2">CRITERIO 3
       </option>
     </optgroup>
</select>

我试图选择具有id-criteria=2和value = 3的选项，所以我这样做了：

$('.parameter-criteria[data-id=2]')
   .find('option[value=3]')
   .find('id-criteria', 2).prop('selected', true);

但这行不通，知道吗？

您可以将两个条件都指定为.find('option[value=3][id-criteria=2]')。

$('.parameter-criteria[data-id=2]')
   .find('option[value=3][id-criteria=2]')
   .prop('selected', true);

        </option>
       <option value="2" data-content="<span class=&quot;badge-min filter d-inline-flex&quot; style=&quot;background-color:#ffb700;&quot;> </span>CRITERIO 2 [51 - 60] - CRITERIO 2" id-criteria="2">CRITERIO 2
       </option>
       <option value="3" data-content="<span class=&quot;badge-min filter d-inline-flex&quot; style=&quot;background-color:#66ff00;&quot;> </span>CRITERIO 3 [61 - 100] - CRITERIO 2" id-criteria="2">CRITERIO 3
       </option>
     </optgroup>
</select>

如何基于多个属性选择特定选项？
