jquery仿淘寶搜索下拉列表實現效果如下：
網上搜索教程：
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>jQuery UI Autocomplete - Default functionality</title>
<link rel="stylesheet" />
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
<script>
$(function() {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL高",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Per高l",
"PHP",
"Python",
"Ruby",
"Scala",
"Sche高"
];
$( "#tags1" ).autocomplete({
source: availableTags
});
$("#tags2").autocomplete({
source: ["a", "b", "c"]
});
//頁面加載
$("#tags3").autocomplete({
source: DataSouce1()
});
//數據庫
$("#tags4").autocomplete({
source: function( request, response ) {
var name=$.ui.autocomplete.escapeRegex( request.term );
response( $.grep( DataSouce2(name), function( item ){
return item;
}) );
}
});
//利用ajax頁面加載就獲取到數據源
function DataSouce1()
{
var mycars=new Array()
for (var i = 0; i <100; i++) {
mycars[i]="高"+i;
};
return mycars;
}
//利用ajax根據輸入的到數據庫查找 相當于
function DataSouce2(name)
{
var mycars=new Array()
for (var i = 0; i <100; i++) {
mycars[i]=name+"_"+i;
};
return mycars;
}
});
</script>
</head>
<body>
<div class="ui-widget">
<label for="tags">Tags: </label>
<input id="tags1" />
<input id="tags2" />
<input id="tags3" />
<input id="tags4" />
</div>
</body>
</html>
使用第四種方法（tags4）實現：
注意：
1.要開啟ajax的同步（true異步，false同步），即：async:false,
2.聲明和返回的集合要寫在 $.ajax({})之外！
3.導包
<link rel="stylesheet"/>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<scriptsrc="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
代碼如下：
<script type="text/javascript">
$("#querys").autocomplete({
source: function( request, response ) {
var name=$.ui.autocomplete.escapeRegex( request.term );
response( $.grep( DataSouce(name), function( item ){
return item;
}) );
}
});
function DataSouce(name)
{
var querylist=new Array();
$.ajax({
type: "get",
data:{q:name},
url:"query",
dataType:'json',
contentType: "application/json",
async:false,
success:function(data){
$(data.data.searchPOJOList).each(function(i){
querylist[i]=data.data.searchPOJOList[i].goodsName;
})
}
})
return querylist;
}
</script>
