MVC3----JQuery UI 自动完成部件

1，标签
<input type="text" data-autocomplete-source="@Url.Action("QuickSearch","Demo")" />

2，需要引用样式和脚本
<link href="@Url.Content("~/Content/themes/base/jquery.ui.all.css")" rel="Stylesheet" type="text/css" />
<script type="text/javascript" class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="@Url.Content("~/Scripts/jquery-ui-1.8.11.min.js")"></script>

3，脚本代码
<script type="text/javascript">
    $(function () {
        $("input[data-autocomplete-source]").each(function () {
            $(this).autocomplete({ source: $(this).attr("data-autocomplete-source") });
        });

    });
</script>

4，控制器代码
public JsonResult QuickSearch(string term)
{
    var s = db.Demos.Where(r => r.Name.Contains(term)).ToList().Select(a => new { value = a.Name });
    //必须允许来自客户端的GET请求。不过这样会出现安全隐患
    return Json(s, JsonRequestBehavior.AllowGet);
}
