使用bootstrap multiselect+thymeleaf实现下拉多选

    <div class="form-group">    
    <label class="col-sm-3 control-label">添加控制点：label>
    <div class="col-sm-3">
        <select class="form-control" id="controlIds" name="controlIds"  multiple="multiple">
            <option th:each="auditControl:${auditControlList}"
                    th:value="${auditControl.id}"
                    th:text="${auditControl.controlDescribe}">
            option>
        select>
    div>
div>

js

<script type="application/javascript" th:src="@{/js/bootstrap-multiselect.js}">
script>
<link rel="stylesheet" th:href="@{/css/bootstrap-multiselect.css}" type="text/css"/>

                for (var i = 0;ifor (var j = 0; j < controlIdsValueArr.length; j++) {
                        if (controlOptions.options[i].value==controlIdsValueArr[j]){
                            console.log(controlIdsValueArr[j])
