基于jquery的文本框与autocomplete结合使用(asp.net+json)

JS脚本引用
复制代码 代码如下:

<script src="/scripts/Jquery.autocomplete/jquery.autocomplete.js" type="text/javascript"></script>

样式引用
复制代码 代码如下:

<style type="text/css" media="all">
@import url("/scripts/Jquery.autocomplete/css/jquery.autocomplete.css");
</style>

JS代码
复制代码 代码如下:

?$(document).ready(function () {
$("#<%=_SearchKeyGame.ClientID %>").autocomplete("./AjaxHandle/AutoComplete.ashx?type=game", {
minChars: 0,
max: 9,
width: 150,
matchContains: true,
autoFill: false,
formatItem: function (row, i, max) {
return row.name;
},
formatMatch: function (row, i, max) {
return row.name + " ";
},
formatResult: function (row) {
return row.name;
}
});
jQuery("#<%=_SearchKeyGame.ClientID %>").result(function (event, data, formatted) {
if (data) {
jQuery("#_SearchKeyGame").attr("value", data.name);
}
else {
}
});
$("#<%=_SearchKeyPlat.ClientID %>").autocomplete("./AjaxHandle/AutoComplete.ashx?type=plat", {
minChars: 0,
max: 9,
width: 150,
matchContains: true,
autoFill: false,
formatItem: function (row, i, max) {
return row.name;
},
formatMatch: function (row, i, max) {
return row.name + " ";
},
formatResult: function (row) {
return row.name;
}
});

AutoComplete 。ashx返回JOSON值
复制代码 代码如下:

string queryStr = context.Request.QueryString["q"];
context.Response.ContentType = "text/plain";
context.Response.Cache.SetNoStore();
string jsponString = "[";
string where = string.Format(" (select dbo.[f_GetPy](platname)) like %{0}% or platname like %{0}%", Common.Common.ToSql(queryStr));
DataTable dt = new Models.Plat().GetDataTable(where,10);
if (dt.Rows.Count > 0)
{
for (int i = 0; i < dt.Rows.Count; i++)
{
jsponString += "{id:\"" + dt.Rows[i]["PlatID"].ToString() + "\",name:\"" + dt.Rows[i]["PlatName"].ToString() + "\"},";
}
}
jsponString = jsponString.Trim(new char[] { , });
jsponString += "]";
context.Response.Write(jsponString);
context.Response.End();
