JQuery chosen插件，实现select多选

步骤：1、js

2、在select标签上添加 multiple="multiple" 属性

3、添加class=" chosen-select" 属性

即可实现多选

默认值选定：

　　1、获取标签默认值，根据格式拆分数据

　　2、使用

$(‘.chosen-select‘).chosen({
			allow_single_deselect : true
		});

		$(‘.chosen-select‘).trigger("liszt:updated");

　　eg:

<div class="form-group ">
		<label class="col-sm-2 control-label no-padding-right" for="moonComplications">中期并发症：</label>
		<select multiple="multiple" class="col-xs-5 col-sm-3 chosen-select" name="moonComplications">
			<option value="ADIPOSEATROPHY">注射部位皮下脂肪萎缩或增生</option>
			<option value="JOINTILL">关节活动障碍</option>
			<option value="GROWSICK">生长障碍</option>
			<option value="CATARACT">白内障</option>
			<option value="OSTEOPOROSIS">骨质疏松</option>
		</select>
	</div>

var $disease = $(‘#diseaseTable‘);
		$(‘#editDisease‘).click(
				function() {
					var objs = $disease.find(‘span‘);
					for ( var index in objs) {
						var obj = objs.eq(index);
						if(obj.attr(‘id‘) == ‘fastComplications‘ || obj.attr(‘id‘) == ‘moonComplications‘ || obj.attr(‘id‘) == ‘slowComplications‘){
							var value = obj.text();
							var selValue = value.split(‘,‘);
							for ( var sel in selValue) {
								$("select[name=‘"+obj.attr(‘id‘)+"‘]").chosen("destroy");
								$("select[name=‘"+obj.attr(‘id‘)+"‘] option[value=‘"+selValue[sel]+"‘]").attr("selected","selected");
								$("select[name=‘"+obj.attr(‘id‘)+"‘]").trigger("liszt:updated");
								$("select[name=‘"+obj.attr(‘id‘)+"‘]").chosen({
									allow_single_deselect : true
								});
							}
						}else{
							$diseaseDialog.find("[name=‘" + obj.attr(‘id‘) + "‘]")
								.val(obj.text());
						}
					}
					//打开对话框
					$diseaseDialog.dialog($.extend(dialogOption, {
						title : "修改"
					}));
					$diseaseDialog.dialog("open");
				});

	$(‘.chosen-select‘).chosen({
			allow_single_deselect : true
		});

		$(‘.chosen-select‘).trigger("liszt:updated");
