}

Web方法：

       Dim wstr As String
       ........................
       ........................
       ........................

       Json_STP = getJson4Table(ds.Tables(0).DefaultView.ToTable, True)
       Json_STP = " var STP=[" + Json_STP + "]" + ";"

       Json_STP_dist = getJson4Table(ds.Tables(0).DefaultView.ToTable(True, StrColumn), True)
       Json_STP_dist = " var STP_dist=[" + Json_STP_dist + "]" + ";"
       Json_STP = Json_STP + vbCrLf + Json_STP_dist

它显示未定义..

but after onSuccess of pageMethod i am unable to access variable "STP_dist"
it showing undefined..
please help me...

推荐答案

function OnSuccess(result) {
     v = STP_dist[0]
}

您需要从结果中获取返回的数据函数的参数，而不是来自 STP_dist [0] ，这里似乎未定义。

You need to get returned data from result argument of function, not from STP_dist[0], which seems undefined here.
