Question

我试图将一系列的参数传到C# ASP。 NET web services using jQuery Ajax. 这里是我的抽样网络方法。注:该功能接受一定数量的参数。当我管理 j时,我获得了500台内服务器Error。使用jquery 1.6.2和NET3.5

[WebMethod]
public string Concat(params string[] arr)
{
    string result = "";
    for (int i = 0; i < arr.Length; i++)
    {
        result += arr[i];
    }
    return result;
}

Here is the jquery:

$(document).ready(function() {

    var myCars=new Array(); 
    myCars[0]="Saab";      
    myCars[1]="Volvo";
    myCars[2]="BMW";

    $.ajax({
        type: "POST",
        url: "WebService.asmx/Concat",
        data: {arr: myCars},        //can t figure out what to put here     
        success: onSuccess,
        Error: onError
    });
});

function onSuccess()
{
    alert("testing");
}

function onError() 
{
    alert("fail");
}

</script>

任何帮助都值得赞赏。

Answer 1

Revised server-side code:

[WebMethod]
public string Concat(List<string> arr)
{
    string result = "";
    for (int i = 0; i < arr.Count; i++)
    {
        result += arr[i];
    }
    return result;
}

此外,在以下表格中添加:Webservice:

[System.Web.Script.Services.ScriptService]

Revised client-side code:

    $(document).ready(function () {

        var myCars = new Array();
        myCars[0] = "Saab";
        myCars[1] = "Volvo";
        myCars[2] = "BMW";

        $.ajax({
            type: "POST",
            url: "WebService.asmx/Concat",
            data: JSON.stringify({ arr: myCars }),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: onSuccess,
            failure: onError
        });
    });

    function onSuccess(response) {
        alert(response.d);
    }

    function onError() {
        alert("fail");
    }

此外,在上述文字中,还提及JSON2,例如:

<script src="http://ajax.cdnjs.com/ajax/libs/json2/20110223/json2.js"></script>

注:

I have tested this under .NET 4 and using jQuery 1.6.4.
Make sure you keep the client and server variable names in sync:
public string Concat(List<string> arr)
data: JSON.stringify({ arr: myCars })
