请问老师ace admin中的多选组件不能正常使用

Question

如图，我一项一项的检查并补全了模板中的css,js引用到本项目的index.html中，但是还是不正常。

我的显示是这样的：

我估计是模板文件中的这段JS没正常执行，如下：

<script type="text/javascript">
			jQuery(function($){
			    var demo1 = $('select[name="duallistbox_demo1[]"]').bootstrapDualListbox({infoTextFiltered: '<span class="label label-purple label-lg">Filtered</span>'});
				var container1 = demo1.bootstrapDualListbox('getContainer');
				container1.find('.btn').addClass('btn-white btn-info btn-bold');
			
				/**var setRatingColors = function() {
					$(this).find('.star-on-png,.star-half-png').addClass('orange2').removeClass('grey');
					$(this).find('.star-off-png').removeClass('orange2').addClass('grey');
				}*/
				$('.rating').raty({
					'cancel' : true,
					'half': true,
					'starType' : 'i'
					/**,
					
					'click': function() {
						setRatingColors.call(this);
					},
					'mouseover': function() {
						setRatingColors.call(this);
					},
					'mouseout': function() {
						setRatingColors.call(this);
					}*/
				})//.find('i:not(.star-raty)').addClass('grey');
				
				
				
				//////////////////
				//select2
				$('.select2').css('width','200px').select2({allowClear:true})
				$('#select2-multiple-style .btn').on('click', function(e){
					var target = $(this).find('input[type=radio]');
					var which = parseInt(target.val());
					if(which == 2) $('.select2').addClass('tag-input-style');
					 else $('.select2').removeClass('tag-input-style');
				});
				
				//////////////////

				 enableFiltering: true,

				 }
				});

				//typeahead.js
				//example taken from plugin's page at: https://twitter.github.io/typeahead.js/examples/
				var substringMatcher = function(strs) {
					return function findMatches(q, cb) {
						var matches, substringRegex;
					 
						// an array that will be populated with substring matches
						matches = [];
					 
						// regex used to determine if a string contains the substring `q`
						substrRegex = new RegExp(q, 'i');
					 
						// iterate through the pool of strings and for any string that
						// contains the substring `q`, add it to the `matches` array
						$.each(strs, function(i, str) {

								// the typeahead jQuery plugin expects suggestions to a
								// JavaScript object, refer to typeahead docs for more info

						cb(matches);

		</script>

老师，这段代码要在vue中怎么正常运行呢？我要怎么样才能使用模板中的多选框呢？

老师，我是这样添加的，把没用到的组件相关初始化代码去掉了，但是效果没变，浏览器还报了这个错误：

Uncaught TypeError: $(...).multiselect is not a function
    at HTMLDocument.eval (course.vue?98a3:302)
    at j (jquery-2.1.4.min.js:2)
    at Object.fireWith [as resolveWith] (jquery-2.1.4.min.js:2)
    at Function.ready (jquery-2.1.4.min.js:2)
    at HTMLDocument.I (jquery-2.1.4.min.js:2)

添加到mounted函数中的代码如下：

jQuery(function($){
  //////////////////
  $('.multiselect').multiselect({
    enableFiltering: true,
    enableHTML: true,
    buttonClass: 'btn btn-white btn-primary',
    templates: {
      button: '<button type="button" class="multiselect dropdown-toggle" data-toggle="dropdown"><span class="multiselect-selected-text"></span> &nbsp;<b class="fa fa-caret-down"></b></button>',
      ul: '<ul class="multiselect-container dropdown-menu"></ul>',
      filter: '<li class="multiselect-item filter"><div class="input-group"><span class="input-group-addon"><i class="fa fa-search"></i></span><input class="form-control multiselect-search" type="text"></div></li>',
      filterClearBtn: '<span class="input-group-btn"><button class="btn btn-default btn-white btn-grey multiselect-clear-filter" type="button"><i class="fa fa-times-circle red2"></i></button></span>',
      li: '<li><a tabindex="0"><label></label></a></li>',
      divider: '<li class="multiselect-item divider"></li>',
      liGroup: '<li class="multiselect-item multiselect-group"><label></label></li>'
    }
  });

有些组件是需要初始执行一些js脚本的，像你这个。

可以在你所在的vue页面的mounted方法，把你这段代码加进去，初始化一下

  老师，我放到mounted中了，还是没解决，浏览器还报了错误：
  Uncaught TypeError: $(...).multiselect is not a function
      at HTMLDocument.eval (course.vue?98a3:302)
      at j (jquery-2.1.4.min.js:2)

      at HTMLDocument.I (jquery-2.1.4.min.js:2)
