Question

我正在尝试通过AJAX将JSON数组传递到vb.net Web函数中，但是我收到了错误。

var retDets = {};


for (var i = 0, len = inputs.length; i < len; i++) {
    if (inputs[i].type === "hidden") {
        if (inputs[i].value !== "") {
            value.push(inputs[i].value)
            name.push(inputs[i].name)
            retDets[inputs[i].name] = inputs[i].value;
        }

//console.log(JSON.stringify(retDets))

args = '{"retDets":"' + JSON.stringify(retDets) + '"}';
aj('payment2', returnFunc, args, failedCallBack);

它假设要调用的web函数是这个（仅用于测试目的）

<WebMethod()>
Public Function payment2(retDets() As String) As String
    Dim a As String() = retDets
    Dim b As String
    Return b
End Function

我收到以下错误：

{"readyState":4,"responseText":"{\"Message\":\"Invalid object passed in, \\u0027:\\u0027 or \\u0027}\\u0027 expected.

执行此操作时：

args = '{"retDets":"' + JSON.stringify(retDets) + '"}';

输出将具有嵌套引号。

{"retDets":"{"asdasd":"asdasdas","ASdasdsad":"khkjhkjhjkh"}"}';

删掉引号

args = '{"retDets":' + JSON.stringify(retDets) + '}';

AJAX JSON格式无效
