项目上用到solr搜索引擎，在输入框输入字符的时候，想做到类似百度的效果，下拉框出现10个建议词条，为此，用上了jQuery UI Autocomplete 做自动补全
jsp页面样例：
<%@ page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>
<%@ include file="/WEB-INF/views/include.jsp" %>
<html>
<head>
<meta charset="utf-8" />
<title>jQuery UI Autocomplete</title>
<link href="${baseURL}/resources/js/jquery-ui/jquery-ui-1.8.17.custom.css" rel="stylesheet" />
<script src="${baseURL}/resources/js/jquery/jquery-1.7.1.min.js"></script>
<script src="${baseURL}/resources/js/jquery-ui/jquery-ui-1.8.17.custom.min.js"></script>
<script>
$(function() {
$("#address").autocomplete({
source: function(request, response) {
$.ajax({
url: "${baseURL}/demoAction/getSuggestions.action",
dataType: "json",
data : {
"address" : $("#address").val(),
"max":10,
"_type":"json"
},
cache : false,
success: function(data) {
//返回的data为List<Address(Long id, String address)>
response( $.map(data, function( item ) {
return {
label: item.address,
value: item.address
}
}));
},
error : function(suggestionRequest, textStatus, error) {
alert(error);
}
});
}
});
});
</script>
</head>
<body>
<h1>jQuery UI Autocomplete</h1>
<input id="address" type="text" />
</body>
</html>
Action类：
package cn.sniper.springmvc.action;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import cn.sniper.springmvc.po.Address;
@Controller
@RequestMapping("/demoAction")
public class DemoAction {
@RequestMapping("/suggestion.action")
public String suggestion() {
return "/demo/demoD";
}
/**
* ajax请求调用
* @return
*/
@RequestMapping("/getSuggestions.action")
public @ResponseBody List<Address> getSuggestions(String address, Integer max) {
List<Address> addressList = new ArrayList<Address>();
addressList.add(new Address(1L, "admin-1"));
addressList.add(new Address(2L, "admin-2"));
return addressList;
}
}
