我的尝试：



在控制器中：



public JsonResult Langs（字符串前缀）

{

CRA_DBEntities dbname = new CRA_DBEntities（）;

var dbnames = new object（）;

// List< string> dbnames;

var dbnameswithid = new object（）;

dbnameswithid = dbname.ConstantDatabaseTypes.Where（x => x.DatabaseName.Contains（Prefix））。选择（ y => new {id = y.ConstDatabaseTypeID，label = y.DatabaseName}）。ToList（）;

// dbnames = dbname.ConstantDatabaseTypes.Where（x => x.DatabaseName。包含（前缀））。选择（y => y.DatabaseName）.ToList（）;

// dbnames = dbname.ConstantDatabaseTypes.Where（x => x.DatabaseName.Contains（term） ））。选择（y => new {y.ConstDatabaseTypeID，y.DatabaseName}）。ToList（）;

// ViewData [dbnamewithid] = dbnameswithid;



返回Json（dbnameswithid，JsonRequestBehavior.AllowGet）;



}







我的JS是：

$（函数（）{

调试器;

var ter = $（＃dbComplete）。val

$（'＃dbComp lete'）。autocomplete（{

source：function（request，response）{

$ .ajax（{

url：'@ Url .Action（Langs）'，

类型：POST，

数据类型：json，

数据：{前缀： request.term}，

成功：函数（数据）

{

响应（$。map（data，function（item）{

alert（item.Name）

}））;

}，

错误：警告（'错误' ）



}）;



}

}）;

}）;

What I have tried:

In controller:

public JsonResult Langs(string Prefix)
{
CRA_DBEntities dbname = new CRA_DBEntities();
var dbnames = new object();
//List<string> dbnames;
var dbnameswithid = new object();
dbnameswithid = dbname.ConstantDatabaseTypes.Where(x => x.DatabaseName.Contains(Prefix)).Select(y => new { id = y.ConstDatabaseTypeID, label = y.DatabaseName }).ToList();
//dbnames = dbname.ConstantDatabaseTypes.Where(x => x.DatabaseName.Contains(Prefix)).Select(y => y.DatabaseName).ToList();
//dbnames = dbname.ConstantDatabaseTypes.Where(x => x.DatabaseName.Contains(term)).Select(y => new { y.ConstDatabaseTypeID, y.DatabaseName }).ToList();
//ViewData["dbnamewithid"] = dbnameswithid;

return Json(dbnameswithid, JsonRequestBehavior.AllowGet);

}



In my JS is:
$(function () {
debugger;
var ter=$("#dbComplete").val
$('#dbComplete').autocomplete({
source: function (request, response) {
$.ajax({
url: '@Url.Action("Langs")',
type: "POST",
datatype: "json",
data: { Prefix: request.term },
success:function(data)
{
response($.map(data, function (item) {
alert(item.Name)
}));
},
error:alert('error')

});

}
});
});

推荐答案

（function（）{

debugge r;

var ter =

(function () {
debugger;
var ter=

（＃dbComplete）。val

("#dbComplete").val

（'＃ dbComplete'）。autocomplete（{

source：function（request，response）{

('#dbComplete').autocomplete({
source: function (request, response) {
