jquery autocomplete实现solr查询字段自动填充并执行查询

页面引入三个JS：

<script type="text/javascript" src="js/jquery-1.7.2.js"></script>
        <script type="text/javascript" src="js/jquery-ui.js"></script>
                <script type="text/javascript" src="js/json.js"></script>

引入JQUERY UI的CSS文件

<link rel="stylesheet" href="css/redmond/jqstyle.css" type="text/css"></link></head>

$(function() {

    function log( message ) {
            $( "<div/>" ).text( message ).prependTo( "#log" );
            $( "#log" ).scrollTop( 0 );
        }

    //http://localhost:8088/solr-src/core0/suggest?q=so&wt=json
    //搜索引擎关键字自动填充
    $( "#city" ).autocomplete({
            source: function( request, response ) {
                $.ajax({

                    url: "http://localhost:8088/solr-src/core0/suggest",
                    dataType: "json",
                    data: {
                        wt:"json",
                        q: request.term
                    },
                    success: function( data ) {

                        response(data.spellcheck.suggestions[1].suggestion)
                    /*
                        response( $.map( data, function( item ) {
                            return {
                                label: item.username,
                                value: item.username
                            }
                        }));
                    */
                    }
                });
            },
            minLength: 2,//输入两个字符才会发送请求

            select: function( event, ui ) {
                log( ui.item ?
                    "Selected: " + ui.item.label :
                    "Nothing selected, input was " + this.value);
                //执行搜索
                $.getJSON("http://localhost:8088/solr-src/core0/select",
                { "q": ui.item.label, "version": "2.2","start":0,"rows":10,"indent":"on","wt":"json" },
                 function(result) {
                 //显示搜索结果,这里简单显示json字符串
                 $("div#content").append(JSON.stringify(result.response.docs));


            });

            },
            open: function() {
                $( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
            },
            close: function() {
                $( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
            }

        });
});

 

html代码：

<div class="ui-widget">
    <label for="city">Your city: </label>
    <input id="city" />
</div>

<div class="ui-widget" style="margin-top:2em; font-family:Arial">
    Result:
    <div id="log" style="height: 200px; width: 300px; overflow: auto;" class="ui-widget-content"></div>
</div>

</div>

solrconfig.xml中配置拼写检查和自动补全组件:

  <!-- A request handler for demonstrating the spellcheck component.

       NOTE: This is purely as an example.  The whole purpose of the
       SpellCheckComponent is to hook it into the request handler that
       handles your normal user queries so that a separate request is
       not needed to get suggestions.

       IN OTHER WORDS, THERE IS REALLY GOOD CHANCE THE SETUP BELOW IS
       NOT WHAT YOU WANT FOR YOUR PRODUCTION SYSTEM!

       See http://wiki.apache.org/solr/SpellCheckComponent for details
       on the request parameters.
