$(document).ready(function(){
$('#search').keyup(function() {
var search = $('#search').val();
if(search.length>2){
$.ajax({
type:"POST",
url: "searchuser",
cache:false,
data: 'search=' + $("#search").val() ,
success: function(response){
$.each(response, function (index, value) {
alert(value);
}
);
},
error: function(e){
alert('Error: ' + e);
}
});
}
});
});
</script>

<body>
<form>
<input id="search" type="text" name="search" />
</form>
</body>
</html>
我从数据库获取值并能够使用alert弹出值但我想使用该值实现自动完成任何人都可以建议我如何使用spring MVC上的示例

而不是上面的代码,只需使用jqueryUI autocompete功能。它将为您提供所需的所有句柄。
$( "#search" ).autocomplete({
source: "searchuser",
minLength: 3,
select: function( event, ui ) {
console.log( ui.item ?
"Selected: " + ui.item.value + " aka " + ui.item.id :
"Nothing selected, input was " + this.value );
}
});
在服务器端,
@RequestMapping(value = "/searchuser", method = RequestMethod.GET)
public void searchUser(HttpServletResponse response,@RequestParam Map<String, String> params) {
String jsonResponse = null;
//Get params.get("term") --> It will be search criteria
String jsonResponse= "[{\"fname\":\"atul\",\"userId\":1,\"name\":\"atul kumar\",\"value\":\"atul kumar\",\"label\":\"atul kumar\"}]";
response.setContentType("application/json");
try {
response.getOutputStream().print(jsonResponse);
} catch (IOException e) {
e.printStackTrace();
}
}
PS:在返回的JSON中,标签和值很重要,因为标签显示在下拉列表中,值是默认设置为输入文本。您也可以使用其他值(如示例中所示)。可以在select:functions(event,ui){}
中进行进一步处理希望它能够消除疑虑。您还应该检查jqueryUI的API和demo
