如何使用自動完成處理

Question

$(".productspecification").autocomplete({ 
      source: '/static/components/autocomplete/listspecification.ashx' 
    }); 

這是我的處理程序

public void ProcessRequest (HttpContext context) { 
    context.Response.ContentType = "application/javascript"; 
    StringBuilder sbSpecs = new StringBuilder(); 
    string[] lines = System.IO.File.ReadAllLines(HttpContext.Current.Server.MapPath("~/YKIOSK/static/components/autocomplete/specifications.txt")); 
    ArrayList result = new ArrayList(); 
    foreach (string s in lines) 
    { 
     if (s.ToLower().Contains(context.Request.QueryString["term"].ToLower())) 
     { 
      result.Add(s); 
     } 
    } 
    context.Response.Write(new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(result)); 
} 

我要到位specifications.txt

你需要使用Ajax的添加web服務獲取數據，然後成功創建自動完成項目。

$("#productspecification").autocomplete({ 
    source: function (request, response) { 
     $.ajax({ 
      url: "/static/components/autocomplete/listspecification.ashx", 
      type: "GET", 
      data: request, 
      success: function (data) { 
       response($.map(data, function (el) { 
        return { 
         label: yourLabel, 
         value: Yourvalue 
        }; 
       })); 
      } 
     }); 
    }, 

然後尋找，如何訪問web服務c＃，asp.net。

//Use the Web Service that your Web server provides. 
     localhost.Service1 MyService = new localhost.Service1(); 
     //Invoke the public WebMethod of the serice. 
var webdata= MyService.MyMethod(); 

或使用web client，http client

Using Client As New HttpClient() 
Dim APIhostUri As String = 「http://localhost:2025/” 
Dim APIResponse As HttpResponseMessage 
Client.BaseAddress = New Uri(APIhostUri)

首先，我想你應該溝處理程序，並從你的腳本中調用Web服務來得到這樣

$("#productspecification").autocomplete({ 
source: function (request, response) { 
    $.ajax({ 
     url: "url to your web method", 
     type: "GET", 
     data: request, 
     success: function (data) { 
      response($.map(data, function (el) { 
       return { 
        label: yourLabel, 
        value: Yourvalue 
       }; 
      })); 
     } 
    }); 
}, 

，如果你仍然是你自動完成數據想要使用處理程序，那麼你需要插入一個web服務消費者模塊來從web服務獲取數據並作爲響應返回。

就是這樣。

public void ProcessRequest (HttpContext context) { 
context.Response.ContentType = "application/javascript"; 
StringBuilder sbSpecs = new StringBuilder(); 
var wcfClient=new YourWcfProxy(); 
var term=context.Request.QueryString["term"]; 
string[] lines = wcfClient.GetLinesFor(term); 
context.Response.Write(new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(result)); 
}
