选择城市组件(多选)

效果：

1、在页面引入css和js文件：

<link href="${staticPath}/resources/js/flcheckbox/css/powerFloat.css" rel="stylesheet" type="text/css" />
<link href="${staticPath}/resources/js/flcheckbox/css/fl-checkbox.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" language="javascript" src="${staticPath}/resources/js/flcheckbox/jquery-powerFloat-min.js"></script>
<script type="text/javascript" language="javascript" src="${staticPath}/resources/js/flcheckbox/jquery-fl-checkbox.js"></script>

2、指定输入框：

$(function(){
	var city = $("#city").FlCheckBox({
		width:$("#city").width(),
		height:300,
		eventType:"click", //事件类型 支持focus click hover
		targetId:"fl-ckb-city",//弹出层
		position:"1-4",
		value:""
	});
		
	$("#choose_city").click(function(){
		city.click();
	});
});

 3、输入框：

<input type="text" id="city" value="" readonly="readonly" style="width:390px;text-overflow:ellipsis;"/>
	<input type="button" id="choose_city" value="选择" />
	<div id="fl-ckb-city" class="fl-ckb" style="display: none;">
		<!--数据选项区-->
		<div class="fl-ckb-items">
			<c:set var="ch" value="" />
			<table width="100%">
				<c:forEach items="${cityListCh}" var="o" varStatus="n">
					<c:if test="${o.ch ne ch}">
						<c:if test="${ch ne ''}">
							</ul></td></tr>
						</c:if>
						<tr>
						<td valign="top">
							<font style="padding-left:15px;font-size: 22px;font-weight: bold;">${o.ch}</font>
						</td><td><ul>
					</c:if>
					<li>
						<input type="checkbox" value="${o.fconfigid }" name="fconfigid" />
						<label title="${o.cityname}">${fn:replace(o.cityname,'市','')}</label>
					</li>
					<c:set var="ch" value="${o.ch}" />
				</c:forEach>
				</ul></td></tr>
			</table>
		</div>
	</div>

 4、数据源“cityListCh”：

//[{fconfigid=69288840, ch=a, cityname=安庆市}, {fconfigid=226719382, ch=a, cityname=安顺市}, {fconfigid=166004284, ch=a, cityname=鞍山市}]
List<Map<String, Object>> cityListCh = findcityList();
//对城市列表按名称的首字拼音进行排序
model.addAttribute("cityListCh", PinyinHelperUtils.cityListCh(cityListCh));
