找不到来源 - 404错误 [英] Source not found - 404 error

问题描述

我正在尝试使用jquery从数据库访问数据。我在我的脚本标签中写了以下代码。

 < script     type   =  text / javascript     语言  =  javascript > ;  
 $（document）.ready（function（）{
  //   function search（）{ 
 $ .ajax（{
 type：  GET ，
 url：location.pathname +   Home / AllCities， 
数据：  {}，
 dataType：  json ，
 contentType：  application / json; charset = utf-8，
成功：OnSuccess，
错误：onerror 
 
}）; 
}）; 
函数onerror （数据）{
 alert（ 错误）; 
 
  var  list =  < select>; 
  for （ var  i =  0 ; i <  data.d.length; i ++）{
 list + =   < option> + data.d [i] .CityName +  < / option>; 
} 
 list + =  < / select>; 
 $（ ＃displayDdl）。append（list）; 
} 
函数OnSuccess（数据）{
 alert（  in success function ）; 
  var  list =  < select> ; 
  for （ var  i =  0 ; i <  data.d.length; i ++）{
 list + =  < option> + data.d [i] .CityName +  < /选项> 中; 
} 
 list + =  < / select>; 
 $（ ＃displayDdl）。append（list）; 
} 
 
 
 < /   script  < span class =code-keyword>>  

我已将所有必要的文件包含在imlement jquery中。

无论路径如何我写在location.pathname之后的url它总是给出404错误。任何人都可以提出为什么会发生这种情况？

解决方案

（document）.ready（function（）{
// function search（）{

.ajax（{
type： GET，
url：location。 pathname + Home / AllCities，
data： {}，
dataType： json，
contentType： application / json; charset = utf-8，
成功：OnSuccess，
错误：onerror

}）;
}）;
函数onerror （数据）{
alert（ 错误）;

var list = < select>;
for （ var i = 0 ; i < data.d.length; i ++）{
list + = < option> + data.d [i] .CityName + < / option>;
}
list + = < / select>;

（ ＃displayDdl）。append（list）;
}
函数OnSuccess（数据）{
alert（ in success function ）;
var list = < select> ;
for （ var i = 0 ; i < data.d.length; i ++）{
list + = < option> + data.d [i] .CityName + < /选项> 中;
}
list + = < / select>;

I am trying to access data from database using jquery. I have written following code in my script tag.

<script type="text/javascript"  language="javascript">
     $(document).ready(function () {
         //function search(){
         $.ajax({
             type: "GET",
             url: location.pathname +"Home/AllCities",
             data: "{}",
             dataType: "json",
             contentType: "application/json; charset=utf-8",
             success: OnSuccess,
             error: onerror

         });
     });
     function onerror(data) {
         alert("error");
         
         var list = "<select>";
         for (var i = 0; i < data.d.length; i++) {
             list += " <option>" + data.d[i].CityName + "</option>";
         }
         list += "</select>";
         $("#displayDdl").append(list);
     }
     function OnSuccess(data) {
         alert("in success function");
         var list = "<select>" ;
         for (var i = 0; i < data.d.length; i++ ) {
             list += " <option>" + data.d[i].CityName + "</option>";
         }
         list += "</select>"; 
         $("#displayDdl").append(list);
     }
    
 
 </script>

I have included all necessary files to imlement jquery.
whatever path i write in the url following location.pathname it always gives 404 error.Can anybody suggest why it is happening?

解决方案

(document).ready(function () { //function search(){

.ajax({ type: "GET", url: location.pathname +"Home/AllCities", data: "{}", dataType: "json", contentType: "application/json; charset=utf-8", success: OnSuccess, error: onerror }); }); function onerror(data) { alert("error"); var list = "<select>"; for (var i = 0; i < data.d.length; i++) { list += " <option>" + data.d[i].CityName + "</option>"; } list += "</select>";

("#displayDdl").append(list); } function OnSuccess(data) { alert("in success function"); var list = "<select>" ; for (var i = 0; i < data.d.length; i++ ) { list += " <option>" + data.d[i].CityName + "</option>"; } list += "</select>";
