输入搜索关键词试试
<script>var xhr = null;
$('#keyword').bind('input propertychange', function () { if (xhr) {
xhr.abort();//如果存在ajax的请求，就放弃请求 } var inputText = $.trim(this.value); if (inputText != "") { //检测键盘输入的内容是否为空，为空就不发出请求 xhr = $.ajax({
type: 'POST',
url: '/index.php/index/index/search',//注意这里输入框输入进行及时提示的方法与action方法不同
cache: false,//不从浏览器缓存中加载请求信息
// data: "keyword=" + inputText, data: {keyword: inputText},
dataType: 'json',
success: function (json) { //console.log(json); json是返回的json数据
if (json.count != 0) { //检测返回的结果是否为空
var lists = ""; // console.log(json[0]._source.title)；
//由于返回多条数据，进行each遍历
$.each(json, function (index, obj) {
//返回多条数据，index是第几条，obj是内容 //处理高亮关键词(这里是输入关键词自动出现的列表的样式) console.log(json[index]._source.title); var searchContent = json[index]._source.title;//标题 var suggestItem = ''; if (searchContent.toLowerCase().indexOf(inputText.toLowerCase()) > -1) { var searchRegExp = new RegExp('(' + inputText + ')', "gi");
suggestItem = searchContent.replace(searchRegExp, ("$1"));
}
suggestItem = suggestItem + " - " + json[index]._type + ' * ' + json[index]._id + ""; //遍历出每一条返回的数据 lists += "
- <a href='/index.php/index/index/search?id=
以上是html部分，下面是php部分
public function getsearch(){
//这个方法是表单点击搜索时action提交的方法 $client = ClientBuilder::create()->build(); $keys = Request::instance()->param('keyword'); $keys = $keys ? $keys : '测试'; $params = [ 'index' => 'article_index',
'type' => 'article_type',
'body' => [ 'query' => [ 'match' => [ 'content' => $keys
]
]
]
]; $response = $client->search($params); $str = ''; $list = $response['hits']['hits']; //pp($list);die;
$str .= '';
$str .= 'idtitlecontent'; foreach ($list as $k => $v) { $str .= '' . $v['_source']['id'] . '' . $v['_source']['title'] . '' . $v['_source']['content'] . '';
} $str .=''; return $str;
} public function search() {
//这部分方法是ajax 在搜索框输入文字时进行提示的方法 /*$client = ClientBuilder::create()->setHosts($hosts)->build();*/
//实例化es类；在项目中引入自动加载文件，并且实例化一个客户端：
$client = ClientBuilder::create()->build(); $keys = Request::instance()->param('keyword');//tp5方法，获取get post数据自动辨别 $keys = $keys ? $keys : '6'; $params = [ 'index' => 'article_index',
'type' => 'article_type',
'body' => [ 'query' => [ 'match' => [ 'content' => $keys
]
]
]
]; $response = $client->search($params); return json($response['hits']['hits']); //pp($response['hits']['hits']);
die;
}
最终效果
