aspjson

Classic ASP JSON Class Reading/Writing

ASPJSON is a free to use project for generating and reading JSON data into a classic ASP object. The class can be used for reading a string of JSON data as well as writing JSON output from an AJAX file. Below are 2 simple examples of both.

Read Json Example:

Json內(nèi)容：

{
  "firstName": "John",
  "lastName" : "Smith",
  "age"      : 25,
  "address"  :
  {
    "streetAddress": "21 2nd Street",
    "city"         : "New York",
    "state"        : "NY",
    "postalCode"   : "10021"
  },
  "phoneNumbers":
  [
    {
        "type"  : "home",
        "number": "212 555-1234"
      },
      {
        "type"  : "fax",
        "number": "646 555-4567"
    }
  ]
}

讀取Json代碼：

<%
Set oJSON = New aspJSON


'Load JSON string
oJSON.loadJSON(jsonstring)


'Get single value
Response.Write oJSON.data("firstName") & "<br>"
Response.Write oJSON.data("address").item("streetAddress") & "<br>"


'Loop through collection
For Each phonenr In oJSON.data("phoneNumbers")
    Set this = oJSON.data("phoneNumbers").item(phonenr)
    Response.Write _
    this.item("type") & ": " & _
    this.item("number") & "<br>"
Next


'Update/Add value
oJSON.data("firstName") = "James"


'Return json string
Response.Write oJSON.JSONoutput()
%>

Write Json Example:

Json內(nèi)容：

{
  "familyName": "Smith",
  "familyMembers":
  [
    {
      "firstName": "John",
      "age": 41,
      "job": 
      {
        "function": "Webdeveloper",
        "salary": 70000
      }
    },
    {
      "firstName": "Suzan",
      "age": 38,
      "interests":
      [
        "Reading",
        "Tennis",
        "Painting"
      ]
    },
    {
      "firstName": "John Jr.",
      "age": 2.5
    }
  ]
}

寫入Json代碼：

<%
Set oJSON = New aspJSON
With oJSON.data
    .Add "familyName", "Smith"                      'Create value
    .Add "familyMembers", oJSON.Collection()
    With oJSON.data("familyMembers")
        .Add 0, oJSON.Collection()                  'Create unnamed object
        With .item(0)
            .Add "firstName", "John"
            .Add "age", 41
            .Add "job", oJSON.Collection()          'Create named object
            With .item("job")
                .Add "function", "Webdeveloper"
                .Add "salary", 70000
            End With
        End With
        .Add 1, oJSON.Collection()
        With .item(1)
            .Add "firstName", "Suzan"
            .Add "age", 38
            .Add "interests", oJSON.Collection()    'Create array
            With .item("interests")
                .Add 0, "Reading"
                .Add 1, "Tennis"
                .Add 2, "Painting"
            End With
        End With
        .Add 2, oJSON.Collection()
        With .item(2)
            .Add "firstName", "John Jr."
            .Add "age", 2.5
        End With
    End With
End With


Response.Write oJSON.JSONoutput()                   'Return json string
