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:
<searchComponent name="spellcheck" class="solr.SpellCheckComponent"> <str name="queryAnalyzerFieldType">textSpell</str> <!-- Multiple "Spell Checkers" can be declared and used by this component --> <!-- a spellchecker built from a field of the main index, and written to disk --> <lst name="spellchecker"> <str name="name">default</str> <str name="field">name</str> <str name="buildOnCommit">true</str> <str name="spellcheckIndexDir">spellchecker</str> <!-- uncomment this to require terms to occur in 1% of the documents in order to be included in the dictionary --> <!-- <float name="thresholdTokenFrequency">.01</float> --> </lst> <!-- a spellchecker that uses a different distance measure --> <!-- <lst name="spellchecker"> <str name="name">jarowinkler</str> <str name="field">spell</str> <str name="distanceMeasure"> org.apache.lucene.search.spell.JaroWinklerDistance </str> <str name="spellcheckIndexDir">spellcheckerJaro</str> </lst> --> <!-- a spellchecker that use an alternate comparator comparatorClass be one of: 1. score (default) 2. freq (Frequency first, then score) 3.

当输入so的时候，如下图：
当选择solr时，如下图：
jquery autocomplete实现solr查询字段自动填充并执行查询
