JS - 基于value属性隐藏选项

Question

当value属性> 23时,我需要隐藏所有选项

<select id="category_ids" class="cat-search-pb" multiple >
    <option value="20">Condo for Sale</option>
    <option value="24">&nbsp;&nbsp;- Jomtien</option>
    <option value="25">&nbsp;&nbsp;- Bang Saray</option>
    <option value="21">Condo for Rent</option>
    <option value="22">House for Sale</option>
    <option value="23">House for Rent</option>
    <option value="14">Land</option>
    <option value="15">Commercial</option>
    <option value="18">New Condo Projects</option>
    <option value="19">New House Projects</option> 
</select>

但是这段代码不起作用:

$(document).ready(function () {
   $(".cat-search-pb option[value>23]").closest('option').hide();
});

谢谢你的想法!

您可以使用具有该属性的选项jquery filter()-请参阅下面的演示：value

$(document).ready(function() {
  $(".cat-search-pb option[value]").filter(function() {
    return +$(this).val() > 23;
  }).hide();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="category_ids" class="cat-search-pb" multiple>

  <option value="20">Condo for Sale</option>
  <option value="24">&nbsp;&nbsp;- Jomtien</option>
  <option value="25">&nbsp;&nbsp;- Bang Saray</option>
  <option value="21">Condo for Rent</option>
  <option value="22">House for Sale</option>
  <option value="23">House for Rent</option>
  <option value="14">Land</option>
  <option value="15">Commercial</option>
  <option value="18">New Condo Projects</option>
  <option value="19">New House Projects</option>
</select>
