请求的ajax页的写法:
protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { if (pTxtValue != "") { Response.Write(GetCity(pTxtValue)); } } } protected string pTxtValue { get { if (!string.IsNullOrEmpty(Request.QueryString["q"])) { return Request.QueryString["q"].Trim(); } else { return ""; } } } protected string GetCity(string cityName) { List<City> lst = CityObject.GetCacheCityList(); FindCity fc = new FindCity(cityName); System.Predicate<City> CityPredicate = new System.Predicate<City>(fc.CityPredicate); List<City> clst = lst.FindAll(CityPredicate); City tmp = null; StringBuilder Builder = new StringBuilder(); for (int i = 0; i < clst.Count; i++) { tmp = (City)clst[i]; Builder.AppendLine(""+tmp.Ename+"|" + tmp.Cname + "|" + tmp.Code + ""); } return Builder.ToString(); } public class FindCity { private string strcity; public FindCity(string city) { this.strcity = city; } public bool CityPredicate(City city) { bool rtn; if (city.Ename.ToLower().StartsWith(strcity.ToLower().Trim()) || city.Cname.StartsWith(strcity.Trim())) { rtn = true; } else { rtn = false; } return rtn; } }
经过测试autocomplete.js文件增加escape对参数进行编码还是不起作用,中文还是乱码。
