[easyUI] autocomplete 简单自动完成以及ajax从服务器端完成

 ???String query = request.getParameter("term");//获取要匹配的参数 ???String[] sources = {"ActionScript", ???????????"AppleScript", ???????????"Asp", ???????????"BASIC", ???????????"C", ???????????"C++", ???????????"Clojure", ???????????"COBOL", ???????????"ColdFusion", ???????????"Erlang", ???????????"Fortran", ???????????"Groovy", ???????????"Haskell", ???????????"Java", ???????????"JavaScript", ???????????"Lisp", ???????????"Perl", ???????????"PHP", ???????????"Python", ???????????"Ruby", ???????????"Scala", ???????????"Scheme"}; ???StringBuilder builder = new StringBuilder("["); ???for(int i=0;i<sources.length;i++){//遍历目标数组，返回符合条件的结果 ???????if(null != query){ ???????????if(sources[i].indexOf(query) >= 0){//表示如果输入了query,sources[i]的String包含String query ???????????????builder.append("{\"label\":\""+sources[i]+"\"},");//拼接成{"label":sources[i]}的JSON数据 ???????????} ???????}else{//如果不输入query,返回所有的sources[i]成为JSON数组. ???????????builder.append("{\"label\":\""+sources[i]+"\"},"); ???????} ???} ???String result = builder.toString();//转换为字符串. ???if(result.endsWith(",")){//因为拼接的结果转换成字符串后,数组内会多出"," ???????result = result.substring(0,result.length()-1);//需要截去最后一个逗号. ???} ???result+="]";//拼接"]" ???out.print(result); ???

 ???$(function() { ???????$( "#tags" ).autocomplete({ ???????????source:function(request,response){ ???????????//request.term估计是将input内容提交后的字符串."term=‘字符串‘",其实等价于传入一个 ???????????//{"term":"字符串"}的JSON数据. 具体在jQuery1.11.10的帮助文档中有所描述,搜get第二个即是. ???????????????$.get("server/demo4_server.jsp","term="+request.term,function(data){ ???????????????//url(目标地址),data(传入数据),callback(回调函数) ???????????????????var result = $.parseJSON(data); ???????????????????response(result);// 输出返回结果 ???????????????}); ???????????} ???????}); ???});
