<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.multiselect/3.3.10/jquery.multiselect.min.js"></script>

<select id="multiselect">
  <option value="option1">Option 1</option>
  <option value="option2">Option 2</option>
  <option value="option3">Option 3</option>
</select>

// 获取多选框
var multiselect = $("#multiselect").multiselect();

// 获取多选框中选中的值
var selectedValues = multiselect.val();

// 将选中值输出到控制台
console.log("Selected values:", selectedValues);
