前端使用config中設定值

//定義ajax設定
var settings = 
{
    "url": "http://xxx.xxx",
    "method": "POST",
    "timeout": 0,
    "headers": {
        "Content-Type": "application/json"
    },
    "data": JSON.stringify({
        "IsinCode": parameterIsinCode,
        "UserID": parameterUserID
    }),
};

//呼叫API
$.ajax(settings).done(function (response)
{
    response = jQuery.parseJSON(response);
    if (response.ResponseCode == '0000')
    {
        alert('新增成功');
    }
    else
    {
        alert('新增失敗' + response.ResponseMessage);
    }
    
});

"url": "<%=$"{System.Configuration.ConfigurationManager.AppSettings["WsWebAPI"]}Observable/Add"%>",

"url": "http://xxx.xxx",
