jquery-ui 输入提示demo

  记录一下工作中点滴,将jquery-ui autocomplete+springmvc+mybatis+oracle 实现输入提示的demo 与大家共享一下.
  具备功能：
  1)支持中文，英文，数字 输入提示
  2)支持按中文首字母提示

  js
 

/**
 * 输入提示
 * @param $searchInput 查询条件input
 * @param url 查询匹配内容的server url
 */
function onAutocomplete($searchInput , url)
{
	 
	$searchInput.autocomplete
	 ({
		source:function(val,parse)
		{
			//获得查询内容
			var searchKeyWord = $.trim(val.term) ;
			if(isNull(searchKeyWord)){
				return ;
			}
			
			//判断查询内容是否为英文
			var isEn = searchKeyWord.isEn() ;
			
            $.ajax({
                url:url,
                data:{caseName:$searchInput.val(),isEn:isEn},
                dataType:'json',
                success:function(r){
                    parse(r);
                }
            });
	    } 
	 });	
}

/**
 * 输入提示
 * 默认在name为‘searchKeyword’ input元素上添加提示功能
 * @param url 查询匹配内容的server url
 */
function onDefaultAutocomplete(url)
{
	var $searchInput = $("input[name='searchKeyword']") ;
	onAutocomplete($searchInput , url);
}

/*
 * 是否为英文
 * 
 */
String.prototype.isEn = function(){
	var reg=/^[a-zA-Z]*$/gi;
	
	if(reg.test(this))
		return true ;
	
	return false;
};

  

  controller
 

@RequestMapping("searchHelp")
	@ResponseBody
	public List<String> searchHelp(@RequestParam(value = "caseName") String caseName,
			@RequestParam(value = "isEn") boolean isEn) throws InterruptedException{
		String userID = PsaspUtils.getLoginUser().getId();
		return this.caseInfoService.getCaseNamesByUserId(caseName,userID,isEn);
	}

  

  service 略
  dao
 

public List<String> getCaseNamesByUserId(String name ,String userID,boolean isEn) {
		Map<String, Object> map=new HashMap<String, Object>();
		map.put("userID", userID);
		map.put("isEn", isEn);
		if(StringUtils.isNotBlank(name))
		{
			map.put("name", "%"+name+"%");
		}
		return getSqlSession().selectList(getGlobalSqlId("getCaseNamesByUserId"),map);
	}
  

  sqlmapper
 

   <select id="getCaseNamesByUserId" parameterType="map" resultType="String">
	 SELECT CI.NAME FROM CASE_INFO CI RIGHT JOIN CDB_SCHEME CS ON CI.SCHEME_ID = CS.ID
	 WHERE ( CI.USER_ID = #{userID} OR (CI.USER_ID != #{userID} AND CI.IS_SHARE = 1))
	  <if test="name != null">
	     <choose>
	        <when test="isEn">
	       	 	AND UPPER(F_PINYIN(CI.NAME)) LIKE '%'||UPPER(#{name})||'%'
