Autocomplete处理XML数据

用jQuery UI的autocomplete插件来实现文本框自动完成功能。

页面代码如下：

    <link rel="Stylesheet" href="Scripts/jquery-ui-1.10.3/themes/base/jquery-ui.css" />
    <link rel="Stylesheet" href="Scripts/jquery-ui-1.10.3/themes/base/jquery.ui.autocomplete.css" />
    <script type="text/javascript" src="Scripts/jquery-ui-1.10.3/jquery-1.9.1.js"></script>
    <script type="text/javascript" src="Scripts/jquery-ui-1.10.3/ui/jquery-ui.js"></script>
    <script type="text/javascript" src="Scripts/jquery-ui-1.10.3/ui/jquery.ui.autocomplete.js"></script>
    <script type="text/javascript">
        jQuery(function () {
            jQuery("#iptbook").autocomplete({
                source: function (request, response) {
                    jQuery.ajax({
                        url: "AutoComplete.aspx",
                        dataType: "xml",
                        data: { key: escape(request.term), ts: new Date().getSeconds() },
                        success: function (data) {
                            response(jQuery("Book", data).map(function () {
                                return {
                                    value: jQuery("title", this).text(),
                                    title: jQuery("title", this).text()
                                }
                            }));
                        }
                    });
                },
                minLength: 1,
                select: function (event, ui) {
                    alert(ui.item.title);
                }
            });

        });
    </script>

<input type="text" id="iptbook" name="iptbook" value="" />

后台代码 输出XML格式数据

    protected override void OnLoad(EventArgs e)
    {
        //简化为直接输出xml
　　　　 StringBuilder xml = new StringBuilder();
        xml.Append("<?xml version="1.0" encoding="gb2312"?>");
        xml.Append("<Books>");
        xml.Append("<Book><id>1</id><title>C#高级编程</title></Book>");
        xml.Append("<Book><id>2</id><title>JavaScript高级程序设计</title></Book>");
        xml.Append("</Books>");
        Response.Write(xml.ToString());
        try
        {
            Response.End();
        }
        catch (Exception ex)
        {

        }

        base.OnLoad(e);
    }
